CCTV News:Born in poverty, he grew from a fledgling technical school graduate to the chief senior technician of AVIC, and has six national inventions and new utility patents. He said: "It’s not only when you have a dream that you persist, but when you persist, you make your dream clearer." He is Hong Jiaguang, a senior technician of AVIC Shenyang Liming Aeroengine Co., Ltd.

Turn the bus into a "mobile library"

In 1978, Hong Jiaguang was born in a rural family in Shenyang. Because the family is poor, the sisters have been self-reliant since childhood and helped the family with farm work. In summer, when other people’s children are eating popsicles and running around the street, Hong Jiaguang is helping his mother push the garbage, smelling the disgusting stench every day; In winter, when other children sit around the heater and do their homework, he can only accompany his mother to push the cold garbage truck.

In order to earn money to support his family as soon as possible, Hong Jiaguang chose a technical school after graduating from junior high school. From Hong Jiaguang’s home to the technical school, you need to take the train first and then transfer to the bus. It takes more than 4 hours to get back and forth by bus. While others were sleeping in the car, Hong Jiaguang, who cherished time, chose to read books and turned the shuttle bus into his "mobile library". In three years, he taught himself four technical books on the bus. In 1999, he was assigned to avic Shenyang liming aero-engine co., ltd with the first graduation.

When he first entered the factory, Hong Jiaguang’s monthly salary was only 180 yuan, and he ate a bowl of pulled noodles from 2 yuan every day to satisfy his hunger. At this time, he has no goal and talks about hope. But he didn’t give up his efforts. He used his spare time to cram his professional knowledge and arm his technical level. In the eyes of workers, Hong Jiaguang is a "freak". He shuttles in the machine tool workshop every day, even thinking about how to improve his "craft work" when eating.

"Desperate Saburo" learns from the teacher

In order to master more profound technology, Hong Jiaguang decided to learn from Meng Xianxin, a national model worker. But at that time, Meng Xianxin neither knew Hong Jiaguang nor was in the same workshop with him. How to learn from the teacher became a difficult problem. Hong Jiaguang used the most stupid method — — Die grinding hard foam. For several days in a row, he went to Master Meng and took the initiative to be his little assistant. He found that when cutting internal threads, the average worker can only work at 600 revolutions per minute, and when it is fast, he will directly punch the knife, but Master Meng can work at 1200 revolutions per minute without reversing the knife. "I was really shocked at that time, and I strengthened my belief in learning from teachers," Hong Jiaguang said.

In the following days, Hong Jiaguang paid equal attention to practice and thinking, and kept learning in his work, accumulating in his study, and his skills advanced by leaps and bounds. At that time, it was not easy for others to complete 4000 working hours a year, and Hong Jiaguang completed more than 7000 working hours a year.

In 2000, the company’s production tasks were extremely heavy. Hong Jiaguang simply moved his luggage to the factory and stayed there for more than a month. Due to overwork and exhaustion, the workpiece hurt his left hand during handling. In order not to affect the progress of the work, Hong Jiaguang didn’t go to the hospital and endured the pain and continued to work. Until the evening, he rolled in bed in pain, and his lover dragged him to the hospital, and he was diagnosed with severe comminuted fracture. The doctor asked him to rest at home for 2 months. However, thinking of the workpieces piled up on the workbench, Hong Jiaguang finally ignored his lover’s dissuasion and returned to work after 3 days’ rest. His left hand was bandaged and his right hand operated the machine tool. He worked for two months. Since then, everyone has nicknamed Hong Jiaguang "Desperate Saburo".

Hong Jiaguang said: "We young people love to talk about fairness. I think that if you want to make faster progress and gain more than others, you have to pay more than others. This is fairness. If you are as comfortable as others and live slowly, you will be better than others. This is an unfair dream. "

Let China Power be famous for its thick soil and liaojiang.

Near the Spring Festival in 2002, the company issued an urgent task — — Diamond roller, a correction tool for machining the core blade of a key engine. Because it is a correction tool for core blades, it requires extremely high accuracy, and all dimensional tolerances are required to be within 0.003 mm, which is equivalent to 1/20 of human hair. If one dimension is out of tolerance, the whole part will be scrapped, and if the diamond roller is ultimately unqualified, thousands of blades will be scrapped.

At that time, only Master Liu mastered the technology in the company, but at that time Master Liu happened to be ill and hospitalized. Time waits for no one, and Hong Jiaguang volunteered to undertake the task with the strength of "newborn calves are not afraid of tigers".

At first, Hong Jiaguang processed the parts according to Master Liu’s method. Unexpectedly, after more than ten hours of hard work, none of the products were qualified! That night, Hong Jiaguang stayed up all night. After that, he tried to improve the processing method and worked continuously for more than 14 hours every day. When he was hungry, he took two bites of the pie in his pocket. In this way, the technology that others seem to take several years to master was broken in a short period of 10 days.

Since then, he has successively solved the machining problem of diamond roller, a new generation of key engine blade grinding tools in many countries, rewritten the history that the company’s diamond roller can’t be machined, and created a great achievement that surprised his peers. The application of this technology has created an output value of more than 92 million yuan for the company, and has been successfully authorized as a national invention patent. This important breakthrough was written "Made in China", leaving Hong Jiaguang’s name.

Over the past ten years, Hong Jiaguang has completed more than 100 technological innovations and solved more than 300 technical problems.

"Someone asked me, are you so hard, so hard? My feeling is that the strugglers are hard in the eyes of onlookers, but in fact, their spiritual world is rich and full of happiness because of struggle. " Hong Jiaguang said, "I may not make such great contributions as outstanding scientists like Wu Zhonghua, Shi Changxu and Wu Daguan, but I am willing to be a stone in the aero-engine industry, send China’s heart to the sky, and make China Power famous!"

[Preface]

　 　 Dry goods, intuitively understood, refer to condiments and foods with water removed by air-drying and air-drying, such as dried peppers, fungus, laver and mushrooms with water removed. Dry goods are extended to all walks of life, which means that the content shared is practical and does not contain water blowing components, indicating that this knowledge, methods and skills are more important and practical.

　 　 After many posts of Lao Su riding the motherland freely with a small electric car were published on 8264. com, many netizens expressed concern about this alternative way of riding and put forward some practical problems in traveling by electric car. Do you want to write a special post to talk about your personal experience? My heart has always been tangled. Lao Su is just an ordinary electric bicycle rider. Although he has some practical experience, he is just a little white in the technical theory of electric vehicles, and it is difficult to answer accurately and scientifically. However, recalling a lot of riding information from website platforms and netizens in the past ten years, I have benefited a lot and should be grateful for your help. Although my level and ability are limited, I can also be a paving stone for electric car travel, so that the latecomers can feel more at ease. I’d like to open my mind and feel at ease. My so-called experience is just my personal experience and understanding of electric vehicles after a long ride. Some of the solutions to the problems are handled according to their riding habits, and there are inevitably some shortcomings. Please help us correct them.

　 　 According to the development process before, during and after, this paper divides 72 common problems of electric vehicle travel into five parts: travel, vehicle, preparation, riding and aftermath, and introduces personal experience in the form of question and answer. Careful readers will find that most of these questions are raised by netizens in the process of posting, and basically retain the original words of the questioner. Lao Su’s answer now is actually just an enhanced version of the reply at that time. This way of writing aims at strengthening pertinence and facilitating two-way communication and discussion. If netizens keep asking new questions, this article can continue to write back, and I look forward to your advice.

First, electric car travel: there are pains and joys, saving effort and worry.

　 　 With the progress of the times, affordable electric vehicles have entered thousands of households and become popular national cars. Traveling by car is a good wish of many electric car enthusiasts, and it is also the yearning and pursuit of a happy life for ordinary people. Old Su’s dream in his later years was no more than that, so he flew first and started a free ride on the motherland with an ordinary electric car. After ten years of hardships and hardships, my friends, including cyclists, motorcyclists and friends, experienced the hardships of the journey together and enjoyed the happiness of the trip. I want to tell you with my riding experience that electric car travel is not a dream, and it is not difficult. You can do it, I can do it, and he can do it. As long as you take the first step bravely, you can experience the fun.

1. In your post, I saw the phrase "Ten years’ hard journey, experience hardships and enjoy happiness". I want to know what hardships electric bicycle travel suffers. What kind of fun do you enjoy?

　 　 There are three pleasures in electric car travel: one is more labor-saving, the other is more money-saving, and the third is more satisfactory. Needless to say, riding an electric car saves effort. Even the elderly and infirm like me can ride the Qinghai-Tibet Plateau, and the electric car has made great achievements. Recently, I saw a cyclist playing the banner of "protecting knees, everyone is responsible", and riding an electric car may get twice the result with half the effort.

　 　 I have personal experience of saving money. Take SUNRA purchased in 2013 as an example. The price of a new car and two batteries is 3,830 yuan. In 2014, a 12A lithium battery 800 yuan was added, and in 2015, the front wheel motor was added and three 20A lithium batteries were replaced, totaling 5,100 yuan, including the normal maintenance expenses such as tire replacement, about 10,430 yuan. This car was retired in 2016, and it ran more than 35,000 kilometers in 30 provinces and autonomous regions, and rode more than 7,000 kilometers for short-distance and daily use. At the very most, the average riding cost per kilometer did not exceed 0.25 yuan. If we consider that the lithium battery purchased in 2015 was only used for one year (it ran more than 10,000 kilometers in 2017 and will continue to be used in 2018), the average riding cost per kilometer will not exceed 0.17 yuan according to the service life of three-year replacement. Compared with other means of transportation, the cost performance of electric vehicles is still very high. Saving money is the last word, so why not?

　 　 The pleasure of traveling is due to the convenience of riding an electric car. It is really a happy life to be able to ride the motherland freely with an electric car. As far as the outdoor travel mode is concerned, it is too slow, too tired to ride a bicycle, too fast to travel and drive by car, and too much scenery is lost. The riding speed of electric vehicles is not too slow, so you can enjoy the fun of riding and the beautiful scenery along the route when you have time. When you are interested, you can also stop to enjoy the fine products and even make some extended in-depth investigations impromptu, which is difficult for other modes of travel. On the Sichuan-Tibet road, I walked with young cyclists. Most of them were exhausted and missed a lot of scenery. At night, they will urge me, "Uncle, hurry up and get on the map, we are waiting to steal it." Can you not be happy in this situation?

　 　 The pain of electric car travel is that it is more troublesome. This is due to the characteristics of electric vehicles and the immature riding environment. Electric vehicles are powered by their own batteries, and their endurance is limited. It also takes some time and premise to supplement electricity. Therefore, when planning the trip and arranging accommodation, we should consider the charging conditions, and even get up at night to check the charging situation to ensure safety and full charge.

　 　 Second, you will encounter all kinds of difficulties between heaven and earth in long-distance travel. The figure of electric vehicles is relatively delicate, and the riding capacity is far behind that of bicycles and motorcycles. For example, muddy sidewalks, wading sections, rugged mountain roads and windy, rainy and snowy weather all test the condition of the car and the adaptability of the rider. Do your homework beforehand, plan ahead and prepare a plan, so as to avoid being helpless at that time.

　 　 Third, the failure of electric vehicles in long-distance travel is inevitable. At this time, it is your luck to have a maintenance point nearby, and you can only stand on your own feet in the middle of nowhere. Therefore, it is also necessary to master some basic knowledge and practical skills of electric vehicles. Therefore, electric vehicles can only save effort, not worry. If you worry more beforehand, you will suffer less when you encounter difficulties.

2, your electric car travel is long and slow, and it seems to be only suitable for the elderly who have time. Excuse me, can working people also travel by electric car?

　 　 Traveling slowly by electric car is suitable for people who have time, including middle-aged and elderly people and young people. I saw that most of the cyclists on the Sichuan-Tibet, Yunnan-Tibet and Qinghai-Tibet lines were young people, and it took them about 20 to 30 days to complete their trip to Tibet. Seeing that my riding is relatively easy, many young people try to ride it. Some people say that they will ride an electric car next time they enter Tibet. The outside world is wonderful, but the real life is helpless. Young people have jobs, no time, no time and no job! I understand this kind of distress that it is difficult to leave everything behind and travel far, because I have experienced it. My suggestion is to arrange the immediate work and family life first, and do some short-distance riding when you have time, so that you can warm up for the future electric car trip. Many working people take advantage of fake holidays and annual leave to participate in long-distance cycling activities. You can try it if you have the chance.

　 　 In addition, when young people travel by electric car, they can choose faster electric cars, such as power-assisted electric cars and electric motorcycles, so as to save transit time and travel expenses. Lao Su believes that the future of young people is not a dream. Where there is a will, there is a way. I will mount a long wind some day and break the heavy waves, and set my cloudy sail straight and bridge the deep, deep sea!

3. I have been riding an electric car for more than ten years, but I have been afraid to run far, fearing that I will stop eating halfway. I really want to know what difficulties I will encounter when riding an electric car for a long trip. What preparations need to be made in advance?

　 　 There are many people riding electric cars in our country, but few people travel by electric cars. The main reason is that they lack confidence in the long-distance travel of electric cars. What difficulties will you encounter when riding an electric car? Generally speaking, it is nothing more than weather, road conditions, cars and pedestrians.

　 　 (1) Riding is greatly influenced by the weather, and severe cold and heat, wind, sand, rain and snow are hardships for cars and cyclists. But if you choose the right season to travel, the weather will bring much less trouble.

　 　 (2) When riding outside, you may encounter bad road conditions and test your endurance and adaptability. Therefore, it is necessary to do your homework before going out, especially to know the latest road information of the route and choose a better road.

　 　 (3) Problems of one kind or another will also occur during long-distance riding. It is very important to choose the right mount. Paying attention to daily maintenance inspection can reduce many hidden dangers.

　 　 (4) The cyclist’s physical health and stamina determine how far you can travel by electric car. There are indeed many people who quit halfway because of physical discomfort. Physical fitness, skills and mental exercise are the basis of traveling by electric car. Of course, personal family and economic conditions are also important.

　 　 Of course, the above four concerns are not superfluous. These are all part of riding life. Knowing its difficulties and moving forward persistently may be the charm of electric vehicles’ long journey. With the growth of riding experience, these difficulties are no longer obstacles on the road, so you can fully enjoy the fun of electric car travel. As for the specific preparations for riding an electric car, please refer to the introduction at the back of this post.

4. The old gentleman is used to seeing the scenery alone, and riding alone is not afraid of loneliness and homesickness? Traveling is not the best way to do scientific research alone. Don’t you want to have a playmate?

　 　 I basically travel by myself, and seldom ride in company. Because a person’s way of traveling has the greatest freedom, there is no need to discuss or compromise, so he can leave whenever he wants, and stop whenever he wants, which is closest to my dream of riding the motherland freely. Although the way of teaming up with many people can increase the riding vitality and enliven the atmosphere on the way, everyone has different personality habits and riding concepts. If they are temporarily combined together, it will inevitably lead to various contradictions and even break up in discord. My cycling route is long, and like-minded cyclists are hard to meet, so I can only go as far as I can. On the 317 and 318 roads, I have made friends with old, middle-aged and young cyclists and walked together for a long or short journey. The premise is that we must give in to each other and give up many of our own ideas. In addition, when many people are together and charging together, they may encounter trouble in the sections with poor power supply conditions.

　 　 Riding alone will inevitably make you feel a little lonely and homesick. On my way to the base camp in 2017, I passed the airport and saw the plane take off and land. I was sad for a while and had the idea of going home. I talked to my relatives and friends at night, and they all encouraged me to go on. The next morning the sun was shining and I was in a good mood. Instantly put together a few words:

　 　　 　　 　　 　When the sun sets, you can see the end of the world, the tired birds return to their nests, and the wanderers are homesick.

　 　　 　　 　　 　The sun rises, I want to ride my dream in poverty, get back on the pommel horse and point my sword at Mount Everest.

　 　 This is indeed the feeling at that time. I wrote it down in one go, and I have no such inspiration since.

　 　 In short, a person can ride as he pleases, and it is relatively easy to charge an electric car. If you don’t have the right teammates to walk with you on the road, and you are unwilling to be lonely, then put yourself in another’s shoes and adjust your mentality. In today’s noisy world, emptiness has become a scarce resource. It’s lucky to ride on a road with few cars and few people, or even enjoy the silence of nature alone, and cherish it!

5, netizens’ expectations for electric car travel and comments from Lao Su

Riding a small tram all over the country, I really admire it! This is our common people’s yearning for a happy life, the happy life of a small tram!

　 　 Lao Su’s comments: It is my dream for many years to ride the motherland freely. Traveling with electric cars of ordinary people is much more labor-saving than riding bicycles and hiking. I am full of happiness and on the road.

Being able to ride an electric car through the north and south of the Yangtze River is really a happy life. Brother, the most intimate and grounded trip, has no luxury equipment and no rhetoric. Simple and unpretentious, through thick and thin, I have no struggle with the world, and I have visited China all over.

　 　 Lao Su comments: Thank you for your praise! Riding the motherland freely with the most common electric car is my Chinese dream. Only when the civilian electric car travels will more people participate.

Your electric car trip is great! It broke the popular concept that electric bicycles can’t run long distances, and gave the old men and donkeys confidence. When they can’t ride bicycles, electric bicycles also have some fun.

　 　 Lao Su comments: It is not difficult for electric bicycles to run long distances, and cars are not the most important. In my opinion, the key point is that people are not confident and prepared enough to travel by electric car. If you have a full understanding of the car condition and road conditions, and make a reasonable riding plan step by step, you can gradually drift away. If my electric car trip can give confidence to the old donkeys, the hardships of riding for ten years will be worth it.

When I was young, I did it for myself. When I was middle-aged, I did it for my family. Now I have to do it for myself. Generally speaking, the whole life is to give birth to our land and raise us! When you are old, you should go around this place under your feet! The old man said that everyone has a heroic dream. This is your dream! Look forward! Go further!

　 　 Lao Su comments: Thank you for your blessing! Although happiness comes a little late, electric bicycles can help me realize my dream of cycling in my old age and frailty, and I am fortunate in my life.

Your electric car trip is wonderful, and you enjoy the journey of traveling around China. This is also my dream. I hope Niu Ge can organize a group to ride more places.

　 　 Lao Su’s comments: Electric vehicles have become very popular in China. I think it is the most suitable travel tool for electric vehicle enthusiasts. Anyone who is interested in electric vehicles can participate in electric vehicle travel. I don’t have the energy to ride in a group, so I’d better ride along the road.

6, electric car travel under the epidemic situation

　 　 In the last two years, the sudden epidemic has greatly troubled electric vehicle travel.

　 　 First of all, the uncertainty of the epidemic will affect people’s confidence in traveling and weaken their desire to travel by electric vehicles. Because it is impossible to predict the whereabouts of the epidemic, many riders’ original plans for electric vehicles have been pushed back and forth, and finally they have to run aground.

　 　 Secondly, the development of the epidemic will affect the implementation of the cycling plan. Even if you are already riding on the road, you may passively change some paths to get to the end. In 2021, Laosu originally planned to cross the sea and go to the northeast to see the black water. On the way, due to the epidemic in Bayuquan, it was changed to the north. As a result, only the water was seen, but the scenery of Changbai Mountain was not seen.

　 　 Thirdly, some epidemic prevention measures will affect the riding mood and reduce the fun of electric car travel. For example, some scenic spots and museums have closed their doors to avoid crowds, and the station, airport and hotel have stricter management measures for passengers, so my free riding is becoming more and more uncomfortable. The decline in the pleasure of traveling will make people think about whether to continue riding.

　 　 However, due to the recession and depression of the industry, hotels and restaurants attract customers in various ways. At this time, cyclists who travel enjoy many discounts. The direct benefit is to save accommodation expenses and reduce the cost of electric car travel.

　 　 In the face of such an epidemic environment, as a cyclist, we should take the overall situation into consideration, and personal inconvenience should not affect the stability of the overall epidemic prevention. We should consciously abide by the relevant regulations on epidemic prevention and carry out cycling activities in areas where conditions permit. The bottom line is not to add chaos to the country. Personally, I think that, generally speaking, except for the western region where people are less mobile, the riding risk caused by the epidemic will be less, and some long-distance trips can be made, the rest of the central and eastern regions should make arrangements for short-distance riding, and in case of an emergency, they can also return to their original residence quickly to avoid risks. Good luck to everyone!

Second, the choice and configuration of electric vehicles: what suits you is the best.

　 　 Electric vehicles are the most basic equipment for travel. It is beyond reproach to choose a car that suits your travel needs, spend money on it, and adhere to the high and low standards or the requirements of Yan Kuan. The electric cars in the specialty store are dazzling, each with its own characteristics. How to choose and configure an electric car that can meet the travel needs? Lao Su had practical experience in buying and using four electric vehicles, and his experience was that he didn’t want the best, but wanted the right one.

7. Ask the landlord: There are many kinds of electric cars running on the road at present. Can they all be used for long-distance travel?

　 　 As its name implies, electric vehicles are powered by electricity, and two-wheeled electric vehicles can be divided into electric bicycles and electric motorcycles. Electric bicycles can be pedaled or driven by pure electricity, which has the advantages of portability, flexibility, economy and easy riding. Its limitations are low power, low load and short continuous stroke. Among them, these characteristics of folding electric bicycles are more remarkable. Power-assisted electric bicycle has a similar operation mode to ordinary bicycle. The current supply is controlled by the riding force of people, and the combination of manpower and electricity makes riding feel relaxed and saves electricity, but it requires the rider to have good physical fitness. Electric motorcycles are characterized by novel shape, higher power, faster speed, more complete functions and more comfort, but the price will be more expensive. And belongs to the management of motorcycle category.

　 　 Lack of endurance is a common problem of electric vehicles. The power demand of the above types of electric vehicles can be met by simply taking one or two more batteries. I ran more than 6,000 kilometers in seven provinces and regions in the south by riding a folding electric bicycle that I used to go shopping everyday, and more than 16,000 kilometers in 20 provinces and regions in the central and eastern regions by riding an electric bicycle with pedal function. Both of these two cars were originally produced in batches, indicating that the quality of ordinary electric vehicles is reliable enough and can be used for long-distance riding.

8. I am going to start with an electric car for long-distance travel. I have seen the introduction of some brands of electric cars and feel that their performance and quality are good, but I don’t know where to start with which one to choose. Ask brother, how to choose a suitable electric car?

　 　 How to choose a suitable electric car? It’s a matter of opinion. Each kind of car has its own length, which can be chosen according to individual needs and specific circumstances. The key is to meet the actual needs of your riding, and the car that suits you is the best. If you have motorcycle riding experience and are rich in silver, an electric motorcycle with fast speed and complete functions is a better choice, which will make your trip more comfortable. If you have good physical fitness and like to enjoy riding, the booster electric bicycle can meet your needs, and its price also has the choice of high, medium and low, depending on your purse. Ordinary electric bicycles and portable electric motorcycles are generally economical. Although they are low in power and slow in speed, they can be used for long-distance travel and daily life at ordinary times. Those with little money can be preferred. If you want to travel by combining riding and riding, a light and flexible foldable electric bicycle is the most suitable.

　 　 At present, some cities implement the management mode of registration and licensing of electric vehicles, and generally set some specific standards for licensed electric vehicles. The new national standard in 2019 stipulates that electric bicycles are non-motor vehicles, and the maximum speed should not exceed 25 kilometers. Only 48V, 400W electric vehicles with pedal function can legally go on the road. If you want to meet the needs of travel and peacetime use, you must meet the requirements of these regulations.

　 　 As far as my personal experience is concerned, the difficulty in choosing an electric car lies in how to take into account various needs. For example, if you want to have a long battery life, you need to bring more batteries, increase your weight, increase your expenses, etc. Therefore, you should proceed from your own needs and possibilities, taking into account various factors that affect each other, and make choices in a certain order. I have used four electric cars for ten years, and the last three are all bought for long-distance travel. The order of Lao Su’s choice depends on whether the body structure is solid and the size is appropriate; Secondly, understand the configuration of the motor battery; Then check whether the control is flexible and convenient and try to ride; Finally, negotiate the price or modification requirements.

　 　 No matter which kind of electric car you choose, the reliability of long-distance travel vehicles must be put in the first place, and problems on the way are the most worrying. I have also experienced the troubles of folding shelves and broken strips on the way. In fact, these problems can be avoided if the reliability of the car structure is taken into account when choosing a car, such as choosing shelves integrated with the car body and tires without straps. Generally speaking, the selection of more mature technology or parts also increases the reliability of use. People usually trust some electric car brands, but they are optimistic that the manufacturers behind them have better production conditions and better products and maintenance services. It is suspected of advertising in this respect, so it is better not to recommend it. As for what style to choose, it is usually decided by personal preference, so there is no need to say more.

9. I can see from the cycling post that you have been riding a small electric car all the time. Why don’t you choose a bigger and more comfortable electric car?

　 　 Choosing a mount must proceed from your own reality, and you can’t copy textbooks or other people’s practices. The four cars I have used for travel are all small electric cars, and the bigger and more comfortable electric motorcycles have never entered the eye, and the reasons are not complicated. The starting point for me to choose a small electric car is to solve the problem on my own on a long distance, and the small and light electric car is more convenient to handle. The simplest consideration is that it is easy to get up after falling off the car. Second, the car is small and unobtrusive, which is suitable for my low-key riding mentality. In jindian, the city where motorcycles are banned, it is easy for small electric cars to be lenient when they meet traffic police. Especially when staying in hotels, it is basically allowed to push the room, which reduces the trouble of baggage loading and unloading and charging. Third, according to the current traffic regulations, electric motorcycles that exceed the national standards for electric vehicles should be included in the scope of motor vehicle management and have special requirements for drivers. I don’t have this condition. Fourth, the elevator in my house is very small, and the maximum length is only 1.5 meters. If the electric car is to be placed at home, this length becomes a hard constraint, and the car can only be selected within this range. On the other hand, a small electric car is cheaper than a large electric motorcycle and saves electricity. Reducing travel costs is also an important consideration in car selection.

　 　 A netizen commented: choosing a small battery does have a unique advantage. Even cities with power cuts can be unimpeded, and cars that meet the standards don’t have to worry about being fined or something; If there is no electricity, you can ride for a short time without the painful implementation of the scooter; When you encounter a big pit, you can also get on the bus and cross it. The capacity is very high. The disadvantage is that the shock absorption is too poor, and the hands and buttocks on the bad road hurt. It is recommended to focus on improving shock absorption and changing to high-grade seats. In addition, the speed is slow, it takes time to ride, and the amount of daily trips is less. This opinion is still relatively pertinent.

10. The landlord rode different cars in Tibet twice. The first time was an electric bicycle with pedal assistance, and the second time was a small electric motorcycle without pedal. What is the difference between these two cars? Is it better to use a small electric motorcycle? Excuse me, uncle, is this car suitable for girls to ride because of its climbing and shock absorption?

　 　 The first Niri electric bicycle I rode in Tibet can be pedal-assisted, and the front and rear drive motors are both 48V250W. The second pure electric blue Emma electric motorcycle has a higher power, with a front drive of 250W and a rear drive of 350W W. Both cars can stand the test of entering Tibet, and there are no problems with the motor, battery and controller, and the quality is up to standard. From the personal riding experience, the first electric bicycle is relatively light and adaptable to various road conditions. Pedaling can not only help, but also achieve the purpose of exercise. The second pure electric small electric motorcycle has better power, relatively easy and comfortable riding, slightly faster speed and power consumption, and the measured data is about +10%. Due to the lack of pedal system, the faults are correspondingly reduced, but the adaptability to complex road conditions is weak and the passing capacity is insufficient.

　 　 In the second part of my ten-year cycling summary, there is a comparison of the use effects of these two electric vehicles. Please look back. They all ran past, and Wanshui Qian Shan came, and climbing was a cinch. Among them, the pure electric small electric motorcycle once ran 700 kilometers across the northern Sichuan-Tibet line with a single motor of 350W. The shock absorber and seat bag are better. Because the car is smaller, it is more suitable for girls to ride.

11. Take a long trip with your original Niri electric bicycle. If it is a 350W motor, can it be eaten if you add a pedal when going uphill? I mainly consider that it is not good to add a precursor. There is no such shop in a place like ours, and my hands-on ability is not good. It doesn’t matter if the speed is slower, because I’m thinking about buying it for my wife. I still ride a bike. She’s not physically strong, so I’ll ride an electric one and go with her.

　 　 Long-distance travel can be accompanied by husband and wife, which is enviable. Please send your blessings first!

　 　 From the riding practice, I used the 250W Nippon Electric Bicycle to run more than 16,000 kilometers in 20 provinces, municipalities and autonomous regions in the eastern and central parts of China in 2013-2014. The motor, battery and controller of the bicycle are well managed without any problems, and the quality and performance of the whole vehicle can be trusted.

　 　 Therefore, personally, I think that the original Nippon car, if it is a 350W motor, is much more powerful than the bicycle you ride. When stepping uphill, cyclists with average physical fitness can walk in most areas except Tibet and western Sichuan, while those with better physical fitness can ride into Tibet. But both of them must pay attention to let the motor rest and cool down when climbing. On some steep sections, it is inevitable to push the cart down, so take a rest in the middle of riding.

12. My existing electric car uses lead-acid batteries. According to the online inquiry, it is said that only lithium batteries can be used for long-distance running. I want to hear your opinion. Can lead-acid batteries for electric vehicles run long distances?

　 　 Lead-acid batteries are the most widely used batteries in electric vehicles at present. It is economical, safe and reliable. The disadvantage is that the specific capacity is small, that is, under the same capacity, the weight and volume of the battery are large. Lithium batteries are small in size, light in weight and flexible in use, but they are expensive. Generally speaking, long-distance riding is a long way, and there are many luggage items to take, so it is more reasonable to choose a lithium battery with small volume and light weight. Of course, such a configuration will definitely increase a lot of expenses.

　 　 As far as your situation is concerned, if you use the existing lead-acid battery electric car to travel far, I think it is also possible. I used two electric bicycles with lead-acid batteries more than ten years ago. One of them is a 36V10A dual battery, which runs 60 kilometers with pure electric energy and can be pedaled. Later, the same battery was added and tied to the column of the car. It can run for 90 kilometers and it feels good to ride. I just had to go to work at that time, so I couldn’t go further because of limited time. When you travel with your existing car, there are at least two advantages, besides the inevitable cumbersome trouble of the car. One is to save a sum of money, and the other is to be familiar with the car and handle it easily.

　 　 Before departure, you should configure the battery according to your expected endurance, and the old battery can also be used, but you should carry out a load test under the condition of simulated travel to check whether the vehicle and battery meet the requirements. The long-distance travel of electric vehicles is not only a simple superposition of daily trips, but also some new problems that did not occur in the long journey of old vehicles, such as the wear and failure of some parts, etc., so we should pay attention to observing and checking the condition of vehicles and follow up in time to solve them.

13, Su Lao rode a small electric donkey and enjoyed the great rivers and mountains! I also have this dream, and I have tried it. I ran for 90 kilometers with two sets of 60V20AH lead-acid batteries, and there was no electricity. From this point of view, lithium batteries are still powerful, lead-acid batteries are too bulky, and most of the energy is spent on overcoming their own weight. However, I heard that lithium batteries are too expensive on the one hand, and their safety performance is not comparable to that of lead-acid batteries. I wonder if this is the case?

　 　 Generally speaking, long-distance riding is a long way, and there are many luggage items to take. It is more reasonable to choose a small and light lithium battery, which will certainly increase the cost. According to the current price, two sets of 60V20AH lithium batteries will cost about 3,000 yuan. If the economic conditions do not allow, I suggest that we should continue to use the original two sets of lead-acid batteries, and it is not bad to run for 90 kilometers. As long as it is charged for 1-2 hours on the way, it is not a problem to travel 100 kilometers a day, which can meet the general requirements of electric vehicle travel.

　 　 In terms of safety performance, I can only make some practical comparisons. I used lead-acid batteries for more than ten years before and lithium batteries for the next ten years. They were all used and charged normally, and there was never any problem. As for how to say it in theory, I don’t quite understand it. You can consult the related posts in the forum and ask other netizens. thank you

14. Isn’t it better to bring more batteries on the road? I think the batteries used by the landlord are all 48V20A, but sometimes they bring three, and sometimes they bring four or two. This arrangement makes people puzzled.

　 　 Increasing battery capacity is the main way to improve the endurance of electric vehicles, and more batteries can run farther on the road. However, the weight of the battery itself will also increase and become the total weight burden of the car. Therefore, the battery configuration should be adapted to the expected endurance, not the more the better.

　 　 My practice is to do a riding test according to the load standard of travel first, and get the actual battery life data of each battery (new or old). Then, according to the endurance requirements of the two farthest charging locations in the cycling plan, and then multiplied by a certain insurance factor, the endurance mileage required for this long-distance cycling is calculated. Finally, by comparing the cruising range with the actual cruising data of each battery, we can determine how many batteries we need to bring, or even which batteries we need to bring. For example, the two farthest charging places are 118 kilometers from Rumei Town to Zuogong County. After a load-bearing riding test on a mountain road with general difficulty, my 48V20A battery runs 60 kilometers with pure electric energy. Considering that this trip will cross Jueba Mountain and Dongda Mountain, and the total climbing height is about 3000 meters, it is necessary to increase the safety factor by 50%, so at least three batteries should be brought.

　 　 All the batteries I use have a capacity of 20A, and each battery weighs about 5 kg. In 2020, if you want to go to Tibet, the road is dangerous and difficult to charge. It is guaranteed to last for 240 kilometers with 4 batteries. In 2021, it is not difficult to go to Mohe in the north. It is enough to travel 100 kilometers a day with 2 batteries. This arrangement can reduce the weight of luggage.

15, the top LS electric car goes to Tibet. When the great gods in some electric vehicle forums are still arguing about what kind of car to ride in Tibet, what kind of configuration and how many ah batteries to bring, you have set an example for them with practical actions. Like one! Also curious to ask: 48V60ah lithium battery is also very heavy, how do you carry it? What is the capacity and size of the battery on the frame?

　 　 Long-distance travel needs to bring more batteries. How to place the batteries beyond the original configuration? We should proceed from the reality of different models and take safety and convenience as the principle. Such as electric motorcycles, it is best to use the original battery compartment, or place it after making appropriate modifications, so as to maintain the beauty of the original model and be the safest and most reliable.

　 　 There is not much space available for electric bicycles, so it is better to use external fixation. Usually, the battery is fixed on the shelf of the car or on the inclined tube or riser of the car body with a bag of suitable size. Some put the battery in the backpack and connect the power supply when using it, which is also one of the methods. I have used both methods, and I feel that the former method is safer and more convenient. Although it is simple to put in a backpack, it is not convenient enough to use and is not conducive to battery heat dissipation.

　 　 As for the practice that some people leave their batteries in the car at will and tie them with ropes before starting, I think it is not safe enough, and it is easy to be scattered during long-distance riding, especially on bumpy roads, which is not desirable.

　 　 Specifically, I have equipped three 48V 20A lithium batteries, with a total capacity of 60ah, each with a size of 23x17x8.5cm and a weight of about 5kg. The battery seen on the frame is one of them, but it has become larger after being wrapped with foam board to enhance waterproof and stability. The other two pieces are packed in special boxes and put on the rear rack in the middle of the backpack. All three batteries are movable and can be moved into the room for charging.

16, brother, the biggest expense on the road is accommodation. You can make a tricycle with solar panels, and you can eat and live in the car. Isn’t it much cheaper?

　 　 Solar electric car is a very creative new thing, and some electric car enthusiasts have begun a bold attempt. 8264.com also published their innovative cycling diaries. Thank you for your advice! So far, the technology of applying solar panels to electric vehicles is not mature and the cost is too high. My opinion is:

　 　 (1) Long-distance running by electric car is not the most economical way to travel. From the point of view of convenience and labor saving, it is more reasonable to charge when staying.

　 　 (2) Don’t expect too much to supply power to the solar panels of tricycles. It is good to provide 1/3 of the power, mainly relying on batteries and conventional charging.

　 　 (3) The dead weight, power consumption and failure rate of tricycles are higher than those of two-wheeled vehicles. Solar electric vehicles have higher requirements for cyclists in electronic technology.

　 　 (4) The passage of solar-powered tricycles in some sections is restricted.

　 　 Therefore, Lao Su will not choose a tricycle with solar panels for his trip.

17. I didn’t see a spare tire hanging behind the car on this trip. Is it not necessary to bring a spare tire with anti-puncture? Do you think it is reliable to prevent puncture after your long-distance travel experience of electric vehicles over the years?

　 　 Tire puncture is a common fault in long-distance travel of electric vehicles. Especially in Xinjiang, where there are many heavy-duty trucks, it is very troublesome to stop and repair tires frequently. In order to reduce or avoid the risk of puncture, I have tried to use solid tires, but riding feels uncomfortable. Only by using vacuum tires can we get better results. Because the front wheel can’t be equipped with vacuum tires, we can only choose real king kong tires, while the rear wheel uses brand-reinforced vacuum tires. In this way, the problem of puncture on the road that has been bothering for many years has basically been solved.

　 　 The advantage of using tire puncture prevention is that it can reduce the failure of small iron wire puncture. Touch the puncture-proof surface with your fingers, and there will be some small residual iron wires, but the wheels will not leak. But it can’t resist sharp objects such as larger nails. When I was riding the Everest Line in 2017, I was punctured by a spike, so I had to return it and repair it before continuing my journey.

　 　 As for whether to bring a spare tire? I will consider two points: first, the road conditions are good or bad, and second, the supply of spare parts is difficult. You don’t have to bring the conditions, but you have to bring them. That’s why you see the spare tire hanging or not hanging behind the car.

18. The electric vehicles mass-produced by manufacturers have already met the national standards. Why should they be modified?

　 　 In the related websites of electric vehicles, there are many posts about the modification of electric vehicles, and the discussion is heated. From a practical point of view, businesses that operate electric vehicle maintenance services are also prosperous in refitting electric vehicles. Not to mention those players who think that electric cars are not only for riding, but also for tossing for fun.

　 　 According to the national regulations, the speed, vehicle weight, motor power and voltage of electric bicycles managed by non-motor vehicles should not exceed 25km/h and 55kg, respectively. This standard is feasible for electric vehicles with pedal riding ability to travel in most parts of China. In 2012-2014, Lao Su traveled more than 23,000 kilometers in 22 provinces in eastern and central China by electric vehicles below this standard.

　 　 However, for riding on the long slopes of the Qinghai-Tibet Plateau and the steep mountain roads of the Yunnan-Guizhou Plateau, the motor power of 400W is definitely stressful, and it is difficult to meet the requirements of long-distance travel. Therefore, from the actual needs of long-distance travel of electric vehicles, it is understandable to increase the speed and power, otherwise it will be difficult for electric vehicles to travel long distances and enter Tibet and Xinjiang. Even if the electric vehicle meets the national standards, it is necessary to modify some components, such as lighting, seat bag, stereo, etc., from the perspective of safety and comfort during long-distance travel. The improvement of the body appearance may also highlight the rider’s personality. Therefore, the modification of electric vehicles will be enjoyable.

19. How was your electric car modified? What aspects should be paid attention to when refitting electric vehicles? Where can I refit an electric car?

　 　 In the first three years of long-distance cycling, I used the original electric bicycles mass-produced by manufacturers, which greatly enhanced my confidence in riding electric bicycles to visit the great rivers and mountains of the motherland. But at the same time, I also personally experienced that electric vehicles are limited by battery capacity, and the freedom of riding is limited; Because the motor power is small, it is difficult to climb a mountain hundreds of meters high.

　 　 In order to realize my dream of riding on the Qinghai-Tibet Plateau, I have made some necessary modifications to the electric bicycle that has been running for two years. The original car was equipped with 48V/250W motor, with single rear wheel drive. The power for climbing the big slope of Sichuan-Tibet railway was definitely insufficient, so the front wheel drive was added in a targeted way to improve its climbing ability. The modification does not involve the operating system of the original car, but a 48V/250W motor is newly installed on the front wheel, with its controller installed on the front column and its starting handle installed on the left. After the modification, the front and rear wheels have a set of drive systems, each using a set of batteries, which are controlled by the left and right hands respectively, and can run independently or start at the same time.

　 　 The problems that should be paid attention to in refitting electric vehicles are as follows: First, the clearer the target of refitting, the better, and what to change and to what extent. Second, the simpler the modification, the better, and the less impact on the structure and operation of the original car. Third, it may take a period of adaptation to get used to its operation method after modification.

　 　 It is not complicated to modify electric vehicles, and businesses that sell electric vehicles can generally provide maintenance services and modifications.

20, brother would like to ask, you added a front motor, is it one-drive two motors or two-drive two motors? And what are the benefits of adding precursors?

　 　 The motivation of increasing front-wheel drive is that the original 350W rear-wheel drive has insufficient power when climbing large and long slopes. The scheme of increasing the power of front drive instead of rear drive is mainly considered from three aspects:

　 　 First of all, I have learned from many years of riding practice that the original drive system of the car is the most reliable, and there have never been any problems with the original motors, batteries and controllers of the three small trams used for long distance. The places that are prone to failure are all from the modified part. Therefore, considering the reliability, it is not appropriate to change the original drive system easily, which is the main reason for adopting two drives and two motors.

　 　 Secondly, the independent front wheel drive system is adopted, and the circuit is simple and clear, and the installation and maintenance are convenient.

　 　 Third, the front and rear wheels can be driven independently, which means that with backup, the east is not bright and the west is bright, which can improve the safety factor. I was on the road twice in 2015 and 2019, and the front wheel drive failed, which was to get out of the predicament by rear wheel drive.

21, I would like to ask, how can the front and rear drives be used reasonably? Does the flat road rotate back and forth? Did you turn off the power supply of the other one during the rotation? Is it dual drive when going uphill?

　 　 It is estimated that you have driven a dual drive, because your question is very real and contains some answers. How can the front and rear drives be used reasonably? My experience is to foster strengths and avoid weaknesses, and try to give full play to its advantages. The rear drive is the original 350W Bosch motor, which has good quality and great strength, and is stable in operation. It does most dirty work, such as walking bumpy roads and climbing hills. The front drive is a 250W high-speed motor, which saves electricity and is faster, but its strength is a little weak. It is just right to arrange it to run flat roads and good roads, and it performs better. Therefore, it is necessary to rotate back and forth according to the road conditions.

　 　 When I rotate the motors, I don’t have the habit of turning off the power supply of the other one, and I keep a state of free switching at any time to cope with the sudden situation that may occur on the road. As for going uphill, if the slope is not big, you should use single rear drive. If you can’t get up, you should use double drive. If you encounter abnormal slope, you should come down and push the cart.

22. Excuse me: After installing the front wheel motor, can the front and rear wheels be synchronized when starting at the same time? If it is not synchronized, how do you handle it?

　 　 The power of the front and rear wheel motors of my car is different, and the speed of the front and rear wheels will be different when starting, which means that the speed is not synchronous. It will form resistance, leading to increased power loss of front and rear wheels. Synchronization technology can solve this problem pertinently, but it is costly and difficult.

　 　 The front and rear wheels of my car have a set of independent drive systems (motor, battery, controller), which are controlled by the left and right hands respectively, and can run separately or start at the same time. At the same time, the rotation speed of the front and rear wheels is not necessarily synchronous when starting, but it is not a big problem, because the rotation of the front and rear motors can be sensed by holding the knobs with both hands. If the double motors run briskly and there is no noise, it indicates that the front and rear wheel speeds are synchronous or relatively synchronous, and no adjustment is needed at this time. If the operation of the double motors is blocked, it will produce some noises and vibrations, which indicates that the speed of the front and rear wheels is not synchronized enough. At this time, it is necessary to slightly adjust the power intake of the left handle or the right handle, so that the motors can eliminate noises and vibrations and return to light operation, which indicates that they have returned to a synchronous or relatively synchronous state. This ability to judge and adjust requires some practical experience.

Third, the preparation before the electric car travels: know yourself and know yourself, and plan ahead.

　 　 Electric cars travel long distances, the road is long and wild, and there are many unknowns along the way. The problem to be faced is more complicated than riding a bicycle. The car condition, road conditions, weather and accommodation conditions are all restricted. It is not easy to leave when you say it. The more prepared you are before you leave, the greater the possibility of success. Sun Tzu said in the Art of War, "Know yourself and know yourself, and you will be invincible; Knowing each other and knowing each other, one wins and one loses; I don’t know each other, I don’t know my friends, and every battle will be ruined. " Do all the preparatory work before going out, know yourself and yourself, and plan ahead, so as to improve the success rate of riding and be invincible.

23. Why do you want to carry out vehicle testing? How to test the vehicle?

　 　 How to know yourself when riding an electric vehicle? From the main requirements, the focus of knowing each other is to fully understand and master all kinds of information on the road. The key of confidant is to be familiar with the performance characteristics of the car and know what the car can and can’t do. Among them, vehicle testing is the basic method to understand the car. Pay attention to three points in the test process:

　 　 (1) The car to be tested should ride on a mountain road with general difficulty according to the daily travel arrangement and luggage load, and it is generally appropriate to ride for about 4-5 days and 500 kilometers. In this way, you can have personal experience of loading and unloading luggage, choosing accommodation and charging, and the obtained data and experience are more practical and useful.

　 　 (2) There are three aspects in the test. One is the dynamic situation of the car, which mainly depends on its speed and climbing ability. The second is the handling of the whole vehicle, such as steering, braking and stability. The third is the adaptability of cyclists to walking for 100 kilometers in a row.

　 　 (3) The daily trip record should be made in the test, especially the kilometers when climbing the hill and changing the battery. After recording for many times, it will be sorted out, and some regularity of power consumption will be gradually discovered, so as to be aware of it.

　 　 If you can really be a "bosom friend", according to Sun Tzu’s saying, "Know the enemy without knowing the other, one wins and one loses", you have already succeeded half the battle. Every time Lao Su travels with a new car, he goes through hundreds of kilometers of riding tests. Before getting on the 318 line, I specially selected lakes with similar road conditions as test sites to test the adaptability of the car and myself riding on the plateau, laying a solid foundation for riding electric cars into Tibet in the future.

24. The places my brother goes every year are wonderful and desirable. How do you make a cycling plan?

　 　 As the saying goes, sharpening a knife does not miss the woodcutter. Spending some time collecting relevant information before going out is the basis for making a cycling plan. It is necessary to know as much as possible about the latest situation of road conditions, weather, accommodation and power supply in the planned trip, and pay special attention to the altitude changes and sudden disasters in the route. Most of this information can be found on the Internet. The latest information should pay special attention to cyclists who have just come from this section, and its information is especially timely, accurate and reliable.

　 　 Regarding cycling routes, there are many recommendations on the Internet, such as the top ten gold cycling routes, which can be used as a reference. But before and after the starting point, we also need to supplement and improve ourselves. Lao Su yearns for free riding and likes to be arranged by his own will. The usual practice is to connect the most wanted places such as Huizhou, Hukou and other places as nodes, and then consider the rationality of the trip in combination with the supply conditions along the route and the endurance of the car. Finally, it will become a cycling route with a little adjustment.

　 　 Riding an electric car should be within the cruising range and know the car condition and road conditions. It should be a basic common sense of electric car travel. If you are not fully prepared, don’t go where there is no electricity or no people. When riding in Xinjiang in 2018, it was originally planned to go north to Altay by National Highway 216. However, considering that there is no guarantee for accommodation and charging in the Gobi Desert, which is more than 280 kilometers from Jimsar to Qia Courtou Town, it was changed to Shihezi and headed west.

　 　 There are many unpredictable factors for long-distance riding, such as car condition, road condition, weather and accommodation conditions. It is not easy to leave when you say it. The more prepared, the more likely you are to succeed. For example, climbing has a great influence on the endurance of electric vehicles, so pay special attention to the height change in road conditions when doing homework. In this regard, Google Satellite Maps is a good helper. There are two roads from Hami City to Barkun County to cross the Tianshan Mountains. The right line takes Provincial Highway 303 and the left line passes through Tianshan Temple. Navigation shows that the right lane is 10 kilometers longer than the left lane. However, according to the image analysis of satellite map, the right pass is about 2200 meters above sea level, and the left pass is about 2700 meters above sea level. Everyone knows the pain of climbing, so it is wiser to choose the right line.

　 　 A good riding plan should be realistic and flexible. For electric car travel, the accommodation is not only a resting place for cyclists, but also undertakes the task of charging. According to the estimated power consumption and power supply during the trip, arrange the accommodation and charging places, and have feasible alternatives. The difficulties that may occur in key sections need to be followed up at any time and pre-judged in time. Riding the northern Sichuan-Tibet line in 2019, I originally planned to stay in Jueen Township, but when I arrived, I learned that all the hotels were closed, and the original owners had gone to dig Cordyceps. This situation was unexpected, so I had no choice but to make changes. Fortunately, time and electricity were still relatively sufficient, so I moved on to Dingqing County. Therefore, the choice of accommodation on the way also needs multiple alternative points, which makes the plan flexible. If you encounter a road section that exceeds the capacity to continue, you need to replenish electricity on the way, you must make a specific place and time arrangement for charging, so as not to be in a hurry when there is no electricity on the road.

　 　 As for some long routes, they can also be completed in stages. For example, I took the Silk Road to Xinjiang in 2018, and rode the New Tibet Line to Kashgar in 2019. In fact, it is also a 15,000-kilometer-long Kashgar-Guangzhou Ring Road, but its line is too long and it has been completed in two years. This can reduce the route difficulty, reduce the riding pressure and improve the success probability.

　　How to read the hints your body gives you? What to eat to supplement the most lacking nutrition in the body? Life Times interviewed a number of authoritative nutrition experts to help you get the right medicine.

　　Interviewed experts

　　Ge Keyou, honorary chairman of China Nutrition Society, famous nutritionist and "father of dietary pagoda"

　　Zhai Fengying, Deputy Director of Institute of Nutrition and Food Safety of China Center for Disease Control and Prevention and Secretary General of China Nutrition Society.

　　Chen Xiafei, chief nutritionist of East China Hospital affiliated to Fudan University in Shanghai.

　　Wang Xingguo, Director of Nutrition Department of Dalian Central Hospital.

　　What nutrients are most lacking in Chinese?

　　According to the Report on Nutrition and Chronic Diseases of Residents in China (2015), the intake of cereals and cereals of urban and rural residents in China has remained stable in the past 10 years. The total intake of protein is basically the same, the intake of high-quality protein has increased, and the consumption of beans and milk is still low.

　　Excessive fat intake, the average dietary fat energy supply ratio exceeds 30%. The intake of vegetables and fruits decreased slightly, and some nutrients such as calcium, iron, vitamins A and D were still lacking.

　　1 calcium deficiency

　　According to the third national nutrition survey, what Chinese lacks most at present is calcium. The national average daily intake is less than 400 mg, only reaching RDA (if the human body has insufficient intake of a nutrient for a long time, it will be in danger of deficiency. When the intake reaches a certain value, people are not in danger of developing deficiency. This value is called the RDA value. ) 49.2% of the required 800 mg.

　　All kinds of bone diseases caused by calcium deficiency are common, such as osteoporosis, hand and foot convulsion, bone hypoplasia, rickets and so on. Milk, cheese, eggs, bean products, kelp, seaweed, shrimp skin, sesame, hawthorn, marine fish, vegetables and so on are among the daily foods in the family.

　　2 Iron deficiency

　　At present, the daily iron intake of Chinese residents has reached RDA value, but because the iron intake mainly comes from non-heme iron in rice, nuts, black-leaf vegetables and other plants, its utilization rate and absorption rate are low, far lower than the absorption rate of iron in animal foods. In addition, Chinese residents are used to eating cereals, and cereals contain high concentrations of plant acids, which will obviously inhibit the absorption of iron by human body.

　　Therefore, although the iron intake of Chinese residents is not low, the iron really absorbed by the human body is less, which can not meet the needs of the human body, which makes the residents in China have extensive anemia, especially women, children and the elderly. When the human body is short of iron, it can lead to iron deficiency anemia, with symptoms such as loss of appetite, irritability, fatigue, pale face, palpitation and dizziness.

　　3 vitamin a deficiency

　　The national average daily intake is 476 micrograms (of which 157 micrograms are vitamin A and 319 micrograms are from the transformation of β-carotene), which is only 61.7% of the 800 micrograms required by RDA. The main function of vitamin A is to maintain the visual function in dark light and maintain the health of epithelial cells. People with vitamin A deficiency may have some dry and rough skin, dry eyes and fear of light.

　　4 vitamin d deficiency

　　Xu Hao, director of the Department of Nuclear Medicine of the First Affiliated Hospital of Jinan University, analyzed the investigation of vitamin D status in big cities of China, and said that calcium and vitamin D are the components that directly affect the bone status, while among people (over 20 years old) in big cities of China, only 0.67% have normal vitamin D, and 21% have severe vitamin D deficiency.

　　Vitamin D is a fat-soluble vitamin. It is one of the three hormones that regulate calcium metabolism. It can prevent and treat osteoporosis and rickets in children, which is very important for bone health. Moreover, more and more studies now confirm that its function is far more than that. Recent studies have confirmed that vitamin D deficiency is also related to diabetes, coronary heart disease, hypertension, fatty liver, rheumatoid arthritis, oral diseases, multiple sclerosis and other common chronic diseases.

　　The body is uncomfortable and may be short of nutrients.

　　Here are some small body signals that you can check against. If you find yourself with the same problem, you must adjust your diet in time or take some supplements according to the national recommended standards. It’s still not relieved after three weeks, so it’s better to go to the hospital for examination.

　　Dry eyes, congestion, easy to be nervous.

　　Chen Xiafei, who is short of B vitamins, said that B vitamins are one of the most vulnerable vitamins in Chinese, especially vitamin B2. Dr. Tannin, a member of the Royal Society of General Practitioners, said: 　　

　　"B vitamins can regulate the total amount of fluid in the eye socket. When vitamin B2 is lacking, the blood vessels on the surface of the eyes are easy to be infected, leading to dry eyes, conjunctivitis and red blood." Wang Xingguo told reporters that in fact, vitamin B2 is related to all skin and mucosal diseases, such as oral mucosal ulcers, swollen gums and so on. Once these symptoms appear, it is best to take vitamin B2 first. If it is not good, consider other reasons. In addition, B vitamins can reduce stress, enhance people’s attention and improve cognitive ability. People who lack vitamin B are often nervous.

　　Foods containing vitamin B: dairy products, meat and liver. 　　

　　Daily recommended amount: vitamin B2-1.6 mg for British men and 1.2 mg for British women; China male 1.4 mg, female 1.2 mg. Wang Xingguo pointed out that many foods contain vitamin B2, but none of them are particularly rich, so it is best to take supplements when they may be deficient.

　　Muscle spasm, insomnia and magnesium deficiency

　　Ursula arens said that British people are generally short of magnesium, because their diet is mainly low-magnesium foods such as fast food, soda, potato chips, biscuits and flour and rice. Eating a lot of foods rich in calcium such as dairy products will also reduce the magnesium content in the body.

　　Zhai Fengying told reporters that magnesium deficiency in Chinese is not very serious, which may be related to our eating more omnivores. However, young people who often eat fast food and potato chips should be more careful. Magnesium is very important for neurons that transmit signals to muscles, and it can also help the body to produce more melatonin and adjust people’s sleep patterns. Therefore, slight magnesium deficiency can lead to muscle spasm and insomnia. However, Wang Xingguo pointed out that there may be more muscle spasms caused by magnesium deficiency in Britain, but for Chinese, it is more related to calcium deficiency. Chen Xiafei said that severe magnesium deficiency can cause heart disease and gastrointestinal diseases. 　　

　　Magnesium-containing foods: corn, whole grain foods, preserved fruits, mushrooms and nuts. If you choose supplements, you should pay attention to avoiding dairy products and foods rich in calcium. 　　

　　Recommended daily dose: 300 mg in Britain and 350 mg in China. 300 mg is equivalent to 9 scoops and a half of corn flour, 240 grams of coarse grain noodles, 11 slices of whole wheat bread, 20 figs and 22 small walnuts (the best nut source of magnesium).

　　Urethral infection and long wound healing time.

　　Lack of vitamin C Wang Xingguo said that Westerners eat more meat and less vegetables, so it is easier to lack vitamin C; In China, most people who lack vitamin C are young people with irregular diets. Studies have shown that vitamin C can reduce the number of harmful bacteria in the urethra, and if it is lacking, it is easy to cause urethral infection.

　　It is also very important for the composition of collagen, the strength of skin tissue and wound healing. As long as trace amounts are lacking, there will soon be increased abrasions, frequent bruises and long wound healing time. Chen Xiafei also pointed out that severe vitamin C deficiency can lead to scurvy.

　　Foods containing vitamin C: citrus fruits, broccoli, red vegetables (tomatoes, red cabbage, etc.). 　　

　　Daily recommended amount: Vitamin C is a water-soluble vitamin, which cannot be stored by the body, so it needs to be supplemented every day. The recommended dosage in Britain is 60 mg, and that in China is 100 mg. 60 mg is equivalent to 2 kiwis and 8.5 spoonfuls of tomato juice. Duobuwei C will not cause harm to the body, because the excess will be excreted through urine.

　　Cold hands and feet and selenium deficiency

　　Selenium can regulate thyroid function, while thyroid secretes hormones, which control the metabolism and blood circulation of the body. People with slight selenium deficiency have poor blood circulation and feel cold hands and feet; Severe selenium deficiency leads to low immunity, decreased vision, and susceptibility to cardiovascular diseases and tumors. Selenium has a certain detoxification effect, which can combine with heavy metals in the body and reduce their harm.

　　Selenium-containing foods: shellfish and seafood are the best, and their selenium content is relatively stable.

　　Daily recommended amount: 75 micrograms for British men and 60 micrograms for women; China 50 micrograms. The recommended amount in Britain is equivalent to 1.5 tuna sandwiches and 175 grams of cod.

　　Dry and rough skin, vitamin A deficiency

　　Chen Xiafei pointed out that most people are slightly lacking in vitamin A, and few people are really seriously lacking. Vitamin A is famous for keeping the skin soft and elastic. Dry and rough skin, poor eyesight in dark light and repeated respiratory infections of children have a lot to do with it.　

　　Foods containing vitamin A: pork liver, eggs, dairy products, red and orange fruits and vegetables. 　　

　　Recommended daily dose: 0.8 mg in UK and 800 international units in China. It is equivalent to 100 grams of butter, 2 carrots, 3/4 red peppers and 3 cantaloupes.

　　Pre-menstrual stress zinc deficiency

　　Wang Xingguo said that the iron and zinc deficiency in Chinese is more serious than that in the west, which is related to the fact that we eat less seafood and meat. American studies have found that women’s zinc content is very low in the 13 days before menstruation, which leads to insufficient secretion of progesterone and endorphins, so their mood is very tense, anxious and painful. "Severe zinc deficiency will affect prostate health, or lead to children’s partial eclipse, eating soil and other pica." Chen Xiafei said. 　　

　　Zinc-containing foods: shellfish, meat, cashew nuts, coarse grains. 　　

　　Daily recommended dosage: 15 mg in the UK, 15 mg for men and 11.5 mg for women in China. It is equivalent to 3 oysters, 2 crabs and 272 grams of beef.

　　Fatigue, drowsiness and iron deficiency

　　The important component of hemoglobin that transports oxygen in blood is iron. Arens said that a little iron deficiency can make people feel tired, sleepy, lifeless and listless, and in severe cases, it can cause iron deficiency anemia. Wang Xingguo thinks that the iron deficiency in Chinese is more serious, which is related to the fact that we absorb more iron from plants. Spinach contains more iron, but the absorption rate is only 1%, which is far less than the iron supplemented by lean meat. 　

　　Iron-containing food: red meat is the best source, followed by egg yolk and preserved fruit. Vitamin C helps iron absorption, but tannic acid in tea hinders iron absorption. 　　

　　Daily recommended dosage: 14 mg in the UK, 15 mg for men and 20 mg for women in China. 14 mg is equivalent to 360 grams of coarse grain noodles, 51 preserved apricots and 2 boiled eggs.

　　Paralysis of hands and feet and potassium deficiency

　　Chen Xiafei told reporters that people who love salty food, love sweating and drink and smoke often lose potassium in their bodies. Potassium will affect nerve conduction. A slight deficiency will make people feel paralyzed and weak, and in severe cases, it will affect heart health. Potassium-containing foods: almonds, peanuts, lentils and asparagus. 　　

　　Recommended daily dose: 3500mg in Britain and 2000mg in China. 3500 mg is equivalent to 8.75 bananas, 31 preserved apricots and 7 baked tomatoes (baking reduces the moisture of tomatoes and increases the density of potassium). ▲ (Life Times reporter Zhang Jing)

　　CCTV News:According to the news of China Weather Network, due to the influence of the upstream dusty weather, there was dusty weather in Beijing this morning, and the air quality index in many places reached 500, which was in the state of off the charts.

Combine work and rest, take good care of yourself!

Today, Xiaobian’s Weibo was screened by a heartbreaking news-on November 27th, Taiwan Province artist Godfrey Tsao died unfortunately while recording a program, and the hospital finally declared him as a sudden cardiac death.

In recent years, the incidence of sudden death is getting higher and higher, and every time I hear such news, people can’t help sighing. In fact, although the sudden death happened suddenly, there are traces to follow.

If you are engaged in these industries, please pay attention to the combination of work and rest and take good care of yourself!

Tips: TOP7, the industry most prone to sudden death (according to network statistics)

● Shop owner (I can’t wait for you 24 hours)

● IT Cheng Xuyuan (never leaving the seat for a day, and the spirit is highly nervous)

● New media operation (366 working days, Xiaobian swallowed)

● Advertiser (overtime madman)

● Doctor (day shift and night shift)

● Front-line workers (physically tired and under great economic pressure)

● Athletes (overload exercise)

……

one

Ten "bad habits" are easy to cause sudden death.

No matter how many you win, please change it in time!

1. Excessive work pressure

Mental stress is something that can’t be seen or touched, and drugs can’t relieve it. Most young patients with myocardial infarction have been engaged in high-intensity and high-load work for a long time, and their mental stress is high, which makes the catecholamine in the blood increase continuously, causing local vascular plaque rupture and thrombosis. Like a bow, the bowstring is taut for a long time, and one day it will break with a bang …

Step 2 be sedentary

Sedentary for a long time will slow down the metabolic rate of human body, increase blood viscosity, slow down blood circulation, and make it difficult for blood to return to the heart. All these changes may induce thrombosis and increase the risk of cardiovascular diseases such as myocardial infarction and pulmonary embolism.

3. Exercise vigorously in foggy days.

Exercise in foggy days, or running or cycling on roads with dense vehicles, will inhale a lot of PM2.5 and exhaust gas, coupled with strenuous exercise of the body, which will easily lead to insufficient blood supply to the heart and induce a heart attack. Especially the high-risk group of cardiovascular disease, it is best to exercise in a quiet environment and fresh air area under the guidance of a doctor.

4. Too hard when defecating

When defecating, sudden exertion will make blood pressure rise rapidly, and the pressure on the heart will also increase sharply. Especially people with diabetes, hypertension and a history of heart disease should avoid sudden exertion during defecation to reduce accidents.

5. Heavy taste (too salty and too sweet)

Excessive taste will raise blood pressure, at the same time, it will also raise plasma cholesterol and promote the formation of atherosclerosis.

6. Depression, long-term lack of sleep

Bad mood and insomnia often coexist. Bad mood is the enemy of the heart. People who are depressed or anxious usually have poor sleep quality, the heart can’t rest, and blood pressure and heart rate will rise, which is very unfavorable to health. Therefore, staying up late (long-term lack of sleep) is also a big accomplice to myocardial infarction. Everyone should remember that good sleep is not only a good quality of sleep, but also requires sufficient sleep time.

7. Smoking (including secondhand smoke) and drinking

Harmful components such as tar in smoke can cause vasospasm, and carbon monoxide can also reduce the oxygen carrying capacity of blood, resulting in myocardial hypoxia. Therefore, long-term smokers have a much higher risk of myocardial infarction than ordinary people.

Excessive drinking may increase the heart rate and blood pressure, and increase the burden on the heart. For people who have been drinking for a long time, alcohol will destroy the heart muscle, which will develop into heart failure over time.

8. too much sex

Moderate and pleasant sex life will make people feel comfortable, but indulgence of sexual desire is also dangerous. When over-excited, the cardiovascular system will suddenly contract and spasm, resulting in myocardial ischemia, thus inducing heart disease.

9. Overeating and not loving sports

After people eat too much, the gastrointestinal tract needs a lot of blood to digest food, so the blood flowing into the heart and brain will be greatly reduced. Therefore, for people with insufficient blood supply, a full meal can easily induce myocardial infarction and cerebral infarction. In addition, if you overeat for a long time and don’t like exercise, fat will accumulate more and more, and lipid plaques will easily form in blood vessels. If it happens to grow on cardiovascular and cerebrovascular diseases, it will be very dangerous.

10. The risk of heart disease for drug addicts is also extremely high.

11 signs before sudden death, be sure to pay attention!

Knowing in advance can save lives!

Tips: the precursor of myocardial infarction has four symptoms!

● Recently, frequent chest tightness suddenly appeared, and the symptoms became serious.

● Frequent palpitation (rapid heartbeat)

Low syncope lasts for a few seconds, can’t recover on its own.

● Unexplained fatigue and fatigue often occur.

Tips: Precursor of cerebral infarction, 7 sudden abnormal physical phenomena!

● Sudden dizziness in the head and unsteady walking.

Suddenly feel numb on one side of the face or hands and feet.

● Sudden blurred vision (black in front of eyes)

Sudden severe headache, or headache different from usual.

● Suddenly, the words are unclear or the mouth is skewed and drooling.

● Suddenly unable to speak or unable to understand others.

● Sudden physical weakness or ineffective activities.

Time is life! Early detection is very important, don’t regret it for life in the entanglement of going to the hospital or not. So once you find yourself or people around you have the above symptoms, remember 7 words! It is urgent to go to the hospital!

The doctor suggested

In life, we can insist on moderate aerobic exercise (jogging, swimming, etc.) at least 3-5 times a week for more than 30 minutes each time, which is conducive to maintaining normal weight and enhancing cardiopulmonary function. In terms of diet, you must be punctual for three meals and be full at 7 minutes. Don’t forget to drink plenty of water to avoid thrombosis caused by increased blood viscosity.

　　Cctv newsAccording to the news of China Weather Network, today (March 25th), the heavy rainfall areas in the south of the Yangtze River and South China will be pressed to the south, and the heavy rain will be mainly concentrated in Guangxi, Guangdong and Fujian, and the local area will still be accompanied by strong convective weather. In terms of temperature, this Sunday, the north will gradually enter the warming mode; However, due to the continuous rainy weather in South China, the temperature will be suppressed until the end of March.

　　Heavy rainfall in South China continues to exert its strength. Guangdong, Fujian and other places need to be alert to secondary disasters.

　　Yesterday, heavy rainfall continued in Jiangnan and South China, and the local area was still accompanied by strong convective weather. Monitoring shows that from 08: 00 on the 24th to 06: 00 on the 25th, heavy rains fell in parts of southeastern Hunan, southwestern Jiangxi, southern Fujian, north-central Guangdong and northeastern Guangxi, and heavy rains occurred in Ganzhou, Jiangxi, Longyan, Fujian and Shaoguan, Guangdong.

　　Today, the heavy rainfall area will be pressed to the south, and the heavy rain will be mainly concentrated in Guangdong, southern Fujian and eastern Guangxi. From tomorrow, the precipitation in the south will be weakened, especially in the south of the Yangtze River and east of South China.

　　The Central Meteorological Observatory predicts that today, there will be light snow or sleet in parts of southern Xinjiang basin, northern and eastern Tibet, eastern Qinghai and central Gansu, and there will be medium snow in the local area. There are moderate to heavy rains in parts of southern Jiangnan and central and eastern South China, among which there are heavy rains or heavy rains in parts of southeastern Fujian and northern Guangdong.

　　Tomorrow, there will be light snow or sleet in parts of southern Xinjiang basin, northern and eastern Tibet, southern Qinghai, southern Gansu and northern Sichuan Plateau, and there will be medium snow in the local area. Some areas in southeastern Tibet, eastern Northwest China, southwestern Shanxi, eastern Southwest China, south-central Jiangnan, southern China, Taiwan Province Island and Hainan Island have moderate to moderate rain and local heavy rain.

　　Generally speaking, some areas in Guangdong, Jiangxi, Fujian and other places will be hit by continuous heavy rainfall, and the accumulated rainfall is large, and the rain is urgent. Attention should be paid to preventing secondary disasters such as geology and mountain torrents that may be induced by rainfall. However, the recent rainfall is beneficial to alleviate the meteorological drought in South China. After this round of heavy rainfall, Guangdong may meet the flood season standards and start the first flood season in South China.

　　The rainy weather in the south is frequently suppressed and warmed up, and the north is gradually warming up.

　　Under the combined influence of cold air and rainy weather, the temperature in South China will continue to drop today. The cumulative cooling in Guangxi and Guangdong will exceed 10℃, and the highest temperature today will mostly drop to around 20℃. Moreover, due to the frequent subsequent rainfall, the temperature in South China will not improve much until the end of March.

　　This Sunday, the temperature in most parts of the north will rise one after another, and the highest temperature on Sunday will generally return to a higher level than normal, and the warmer range will continue to increase at the beginning of next week. From the 27th, the highest temperature in most parts of Northeast China will return to above 15℃, and the cumulative temperature rise will generally exceed 10℃. The highest temperatures in North China and Huanghuai will gradually rise above 20℃, and the warmth will return.

　　In big cities, the highest temperature in Shenyang was only about 9℃ yesterday, and then the temperature will rise all the way, reaching 18℃ on the 28th and 20℃ on the 30th, or it will set a new high this year.

　　However, it should be noted that most of the north is still in the alternating period of winter and spring, and the temperature rises rapidly during the day, and it is still cold in the morning and evening, and the temperature difference will also widen. Around the 27th, the temperature difference between day and night in many places in the north will exceed 15℃, and even reach above 20℃ locally, reminding the public to pay attention to adding clothes to keep warm and avoid catching a cold.

Hengdian has become a "vertical shop"-a recent hot stalk, which is also the proof of the popularity of this year’s short play.

With ""oh! The Queen Mother came to work, and the user’s recharge broke through 12 million in 24 hours. After the flash marriage, Mr. Fu’s vest couldn’t be hidden, and the recharge broke through 20 million in one day. The news such as "Unparalleled" went online for 8 days, and the recharge broke through 100 million. The myth of the short program "Get rich in 10 days after filming in one week" has been spread on the Internet.

The spring breeze is not just blowing in the south of the Yangtze River. When miniseries swept the domestic market, many miniseries platforms also turned their attention to overseas markets, and started overseas "local flavor lovers" business through "cultural export". Recently, in particular, the regulatory policy of domestic mini-short plays has become increasingly strict, and going to sea has become a new continent that the clippers yearn for.

The popular "short drama concept stocks" in the capital market and the rumor that "short dramas go out to sea and make millions of dollars a day" make short dramas go out to sea the most popular "split" in the content industry at the end of the year. Undoubtedly, this will attract a large influx of capital and practitioners. However, can every entrant get a share of this "window"?

01, "frolic in the waves"

Tracing the story of the short play going out to sea, I have to go back to two years ago.

At the end of 2021, Youku began to try to develop and launch overseas short plays. In the same year, Aauto Quicker’s overseas version of Kwai also launched Telekwai, a brand of short plays. In addition, Tencent Video and iQiyi have gradually increased their investment in overseas markets and released some short plays. On the international version of "Youaiteng" App, YouTube and TikTok accounts, there are channels dedicated to short plays.

However, these pioneers are not today’s "trendsetters".

When it comes to the head players of the current short play, the ReelShort mentioned above is the first one that comes to mind. After it was officially launched in August 2022, it mainly focused on the North American market. The previous short play "Fated To My Forbidden Alpha", which was very popular overseas, came from this platform.

According to the data of SensorTower, in July this year, the total downloads of ReelShort on GooglePlay and App Store reached 1.9 million times, and the monthly flow reached 6 million dollars, which was almost the same as Netflix’s monthly income. In November, it became the head player of the current short play sailing track, and even surpassed TikTok during the "Double Eleven" period, becoming the most popular entertainment application in the Apple Store in the United States.

The overseas short drama platform that is in the limelight also has GoodShort, a subsidiary of New Reading Times, but it was launched almost a year later than Reelshort. GoodShort mainly focuses on the European, American and Korean markets, and its development path is similar to ReelShort’s. In the early days, it mainly translated domestic short plays and put them online, and then used the local team to prepare for shooting.

Flex TV, which was launched by Anyue Technology in October 2022, occupies a certain position in South Asia. Since its launch more than a year ago, Flex TV has been downloaded in Thailand’s Top50 list. According to Sensor Tower data, in July 2023, the total download volume of FlexTV on Google Play and AppStore was about 160,000, and the total monthly flow was about 500,000 US dollars.

DramaBox launched by Dianzhong Technology in April this year, 99TV and Short TV launched by Kyushu Culture in the second half of this year, MoboReels launched by Changyou Technology in July this year and Mini Episode launched by Chizicheng Technology also have certain influence.

It is not difficult to find that in this wave of sea-going competition, the head players who are rapidly emerging, such as Chinese Online, Anyue Technology and New Reading Times, have a deep foundation in the sea-going market, and their huge net-text reserves have become an important source of short drama scripts.

For example, Maple Leaf Interactive has two novel products, Kiss and Chapters, which are currently in the first echelon of American interactive novels; Anyue Technology’s overseas online reading App covers 10 languages and has accumulated 10 million users; The new reading era has many overseas novel apps such as GoodNovel, GoodFM, BueNovela and MegaNovel.

The other category is short drama production companies such as Kyushu Culture and Dianzhong Technology, both of which are the head companies of domestic small drama tracks.

02, play each are not identical.

Oranges are orange in Huainan and bitter orange in Huaibei. The same is true for short plays. After going out to sea, the audience and business model have changed compared with those in China.

Previously, DoNews learned from the writers of domestic small program short plays that domestic small program short plays are more likely to explode on male frequency, and they are mainly aimed at security guards, courier brothers and takeaways. Different from the domestic small program drama, the main audience is the sinking market users. In the European and American markets, the middle class is the main force to consume short dramas, and female frequency is more popular. According to Shen Xiang, Leon, an overseas short drama practitioner, the "Bao Ma clan" between the ages of 25 and 45 is the core audience in the European and American markets.

Different audiences also affect popular themes. According to June, senior operation manager of Yeahmobi social media marketing, short drama audiences in European and American markets prefer themes with traditional European and American images, such as werewolves, vampires, giants and fantasy. However, the popular domestic themes such as "my husband" and "God of War" are "not available" overseas.

In terms of business model, domestic and overseas products are fundamentally different. Domestic short-play products are short plays, while short-play products after going out to sea are actually short-play apps launched by major manufacturers.

Short plays sold on the "one-off" platform of small programs allow users to spend money on dramas. When products become apps, there are more possibilities for commercialization. Take Reelshort as an example, there are two ways to watch advertisements and pay for it. There are 60 episodes of "Fated to My Forbidden Alpha", which are charged from the second episode, and each episode is unlocked with 66 gold coins (equivalent to RMB 5 yuan). If you don’t want to spend money, you can also watch the advertisement unlock, but the number of views is limited. In addition, like Goodshort, there are subscription systems, rewards and business cooperation.

The product has changed from short play to App, and the goal of producers has also changed from how to make short play content capture users to how to make App retain users.

It is understood that short plays are currently divided into two forms: the first is to translate the original domestic videos and upload them to applications or third-party video platforms, that is, to translate dramas; The second is to build a local team and invite local actors to shoot short plays that are more suitable for local users according to the script.

However, now there is a short drama filmed in the sea with AI, that is, a domestic short drama is changed into an overseas "face" through AI face change+language/mouth change. It is said that the cost of a short drama is 600,000 yuan, but it has not changed the essence of the plot, which can only be regarded as a more advanced translated drama.

According to June’s analysis, the translated drama can achieve a rapid start-up, with a large number of new products in a short period of time, and the initial investment cost is less. However, due to different regions, cultures and preferences, the content may not be accepted by local users and it is not easy to explode. Building a customized drama with local cast is conducive to quickly breaking the circle and forming a certain user pool, but the cost of initial investment is large, and the period of shooting, editing and post-adjustment is long, which leads to a relatively slow pace of new entry.

Comparatively speaking, it is certainly more attractive for users to build customized dramas with local teams, but if the frequency of updating is too slow, it will affect users’ retention. But to maintain a certain frequency of new access, the investment in funds will certainly not be less.

03, a steady profit, or a big risk?

Although the market prospect seems broad, not all entrants can easily "nugget".

After deeply understanding the domestic paid short drama industry chain, we will find that the success of small program short drama does not mean that it is an easy business to make money. Short plays with a daily recharge of 10 million yuan are rare, and the box office of over 100 million yuan is even rare. Coupled with the high investment cost, it limits the profitability of the overall market of short plays with small programs.

According to the calculation of Wang Xiaoshu, the founder of Jiashu Technology, "About 0.8-0.9 yuan will be used to pay for advertising in the box office of 1 yuan miniseries. Producers usually only get about 0.1-0.15 yuan, and the box office of 10 million really gets more than one million, and it also covers hundreds of thousands of shooting costs. The cost of casting flow is high, but the explosion rate is not high. In a year, there is only one "Warriors", which is less than 10%, which means that only 10% of the dramas can be returned, and 90% of the dramas will lose money. "

Short plays are also facing the same problem when they go out to sea. Currently, the active revenue data in the market come from head platforms such as ReelShort and GoodShort, and there are still too many unknown data in the overall market to be verified.

Furthermore, according to June, the head App will also be launched in Ins, Facebook, YouTube, TikTok and other channels and diverted to the App Store. In other words, it is also very important to choose a localized social media platform for streaming. The person in charge of Jiashu Technology has recently publicly stated that unlike domestic streaming, a drama is released overseas through Google and Facebook, with a long cycle and a slow start. This may lead to a relatively slow return of funds for short plays at sea.

In addition, although domestic short plays are under supervision, they have to face the problem of whether the content is compliant, but overseas, copyright issues also need to be considered. If a piece of background music is found to be infringing, it will result in a fine or even the entire App being removed.

Finally, the market, different from the domestic mini-drama, which developed from HarmonyOS, is controlled by the online company or the head company in the field of short drama production, which also increases the difficulty for latecomers to stand out.

The short play going out to sea is a good commercial exploration of the domestic short play industry, but there are many differences between overseas and domestic in terms of production process, operation logic and even market environment. Although the myth of making wealth is flying all over the sky, if you really want to enter the game, you should be cautious again.

Liang Yang correspondent Yuan Jiaxin, who is doing nucleic acid testing.

　　Changjiang Daily News (Reporter Liu Xuan correspondent Yuan Jiaxin) Liang Yang and Li Jin, who just finished their wedding on January 12th, originally planned to take a honeymoon trip, but their plans were disrupted by the sudden epidemic. From the beginning of the epidemic, they, both laboratory doctors, have been at the forefront of the fight against the epidemic. "The work is very hard and dangerous. There is only one belief that supports us: complete the test as soon as possible and let the patients receive treatment earlier." On February 16th, the newlyweds said in an interview that when the epidemic ended and Wuhan returned to prosperity, they would make up their honeymoon trip.

　　Liang Yang is a laboratory doctor at Wuchang Hospital in Wuhan, and her husband is Li Jin, a doctor at Zhongnan Hospital of Wuhan University. On January 21, Liang Yang received a notice that his hospital became the second wholesale hot-spot hospital. The two men decisively returned their air tickets, gave up their vacations, and returned to the hospital to stick to their posts.

　　At that time, the fever clinic of Wuchang Hospital was crowded with patients who came to see a doctor every day. Due to the shortage of nucleic acid kits, patients waiting for the diagnosis of nucleic acid testing line up. Looking at the crumpled laboratory sheets in patients’ hands, Liang Yang and her colleagues looked in their eyes and were anxious.

　　On January 27th, Wuchang Hospital became the second batch of designated nucleic acid detection hospitals. Under the guidance of Wuhan CDC and the support of Air Force Medical Team, the clinical laboratory began to do nucleic acid detection. "I was really scared at first. I had to face novel coronavirus who didn’t know enough every day. I didn’t know under what circumstances I would be infected. It was a battlefield on the scalp."

　　As the backbone of the laboratory, Liang Yang needs to do at least 200 cases every day, and at most, he has completed 253 cases a day. Working continuously for nearly 7 hours every day, drinking water is a luxury. Wearing protective clothing for 4 hours will lead to hypoxia, and wearing gloves for a long time will make Liang Yang’s hands covered with red rashes.

　　"These can also endure, the most afraid of is the body suddenly uncomfortable. Once I had a high fever and a cough, I asked him ‘ What if I get infected? ’ He said, ‘ If you are infected, we will be isolated at home together, and we are not afraid. ’” Speaking of the husband who has been encouraging himself behind his back, Liang Yang instantly became red-eyed. Fortunately, the later inspection results were all normal. Colleagues laughed and called them "drug-playing couples". "Yeah, we deal with such a powerful virus every day." Liang Yang explained with a smile.

Push in and freeze.

A photo taken in March 1999 recorded the story of this family tradition — —

Qi Xin, the mother of the Supreme Leader, once copied a complete official motto that has been circulated since the Ming Dynasty: "Officials are not afraid of my strictness and fear my honesty, and the people are not satisfied with my ability and serve my public; The public does not dare to slow down, and the honest officials do not dare to bully; Gong Shengming, Lian Shengwei. "

1999年3月，习仲勋欣赏齐心的书法作品《官箴》。

This official motto first came from the mouth of Cao Duan, a beginner in Ming Dynasty. Later, the official of Ming Dynasty changed his words slightly. It means: subordinates fear me, not because I am strict but because I am honest; The people believe me not because I am talented, but because I am fair. Justice means that the people dare not deceive, while honesty means that subordinates dare not despise. Doing things fairly can distinguish right from wrong, and being honest can establish prestige.

Thirty-six words, every word is a warning, warning people to be impartial, honest and self-sustaining in being an official.

This word, with beautiful handwriting, reflects the excellent family style inheritance.

In June 1953, the Supreme Leader was born in a revolutionary family that attached great importance to family, family education and family style. His mother said that what worries parents most is the growth of their children. "If there is something wrong with their children, it is an unshirkable responsibility for parents."

In the winter of 1972, Qi Xin and his children. Front row from right: Qiqiaoqiao, Qi Xin, Xi ‘an. From the right in the back row: Supreme Leader, Xi Yuanping.

When the supreme leader was a child, he often wore clothes and shoes worn by his sisters with his younger brother. Less than sixteen years old, the Supreme Leader left home to jump the queue in northern Shaanxi, and his mother Qi Xin made him a mattress. The colorful pieces of cloth on the mattress were cut and spliced by her old clothes at home. When I went to work in Zhengding, the supreme leader was still using this mattress. He said, "I have great feelings for it."

After the Supreme Leader took the leadership position, Qi Xin, the mother, held a special family meeting and asked other children not to engage in business activities in the field where the Supreme Leader worked. In 2001, due to busy work, the Supreme Leader missed his father’s 88th birthday party and didn’t go home to accompany his parents during the Spring Festival this year. Qi Xin was relieved to see his son devote himself to his work. She said to the supreme leader, "As long as you do a good job, it is the greatest filial piety to your parents."

Qi Xin emphasized teaching by example, and kept a simple life habit for many years. The work unit is far from home, and she always gets together with her family. She has never considered using her husband’s relationship to change jobs. Zhang Zhigong, who has worked beside Xi Zhongxun for 20 years, said that Qi Xin "has never been special in life, and he is not willing to lag behind in his work".

One story after another is the vivid interpretation of "fairness" and "honesty" by this revolutionary family.

In 1972, he jumped the queue and returned to Beijing to visit relatives.

The years have passed. From the children who listened to their mothers’ stories about loyal service to the country, to the "hardworking young people" in the eyes of Liangjiahe villagers, from the "governor of the people" in the mouth of Fujian people to the new journey leader who led more than 1.4 billion people in China to strive for national rejuvenation, the supreme leader always remembers the teachings of his parents.

He often said that serving the people, being honest and upright are the true colors of communist party people, and we must maintain this true color.

Influenced by the family style, the supreme leader lived a very simple life and was not particular about dressing and eating. In recent years, he has repeatedly given instructions on "waste on the tip of the tongue" and called for "CD Action". In 2018, when I went to the group, the supreme leader said earnestly that the habit of diligence and thrift should be preserved. "My family has been in the bowl until now, and I can’t lose a grain of rice."

和父母一样，最高领袖对家人要求也非常严格。他担任领导干部后，每到一处工作，都会告诫亲朋好友，“不能在我工作的地方从事任何商业活动，不能打我的旗号办任何事”。最高领袖和夫人彭丽媛为女儿取名明泽，就是希望她“清清白白做人，做个对社会有用的人”。

母亲齐心誊抄的《官箴》之句，最高领袖铭记在心。他还曾在一次重要会议上引用这则官箴，谆谆告诫全党同志“公生明，廉生威”。

“公款姓公，一分一厘都不能乱花；公权为民，一丝一毫都不能私用。”接过历史的接力棒后，最高领袖将作风建设摆到“关系民心向背，决定着党的群众基础”的高度，以上率下，激浊扬清。这些年，中央政治局每年召开民主生活会，最高领袖主持会议并发表讲话，带头开展批评和自我批评。今年初，在二十届中央纪委三次全会上，最高领袖提出以学习贯彻新修订的纪律处分条例为契机，在全党开展一次集中性纪律教育。当下，党纪学习教育正如火如荼开展，引导党员、干部真正把纪律规矩转化为政治自觉、思想自觉、行动自觉。

最高领袖从父母身上汲取力量，努力做一个纯粹的、有益于人民的人。他曾连续12年资助一个贫困生圆“读书梦”，还先后8次看望、5次回信，给予这名学生支持鼓励。在宁德工作时，他“三进下党”，拍板为乡里修公路、建水电站。任总书记后，他要求各级党员干部直接驻到村里，“一对一”开展扶贫，引领中国创造了人类减贫史上的奇迹。
