Original Dr. Wang Cardiovascular Doctor Wang Cardiovascular Doctor Wang

Every time Dr. Wang finishes prescribing statins in the outpatient department, he must tell the patients a few more words: Be sure to check again! Don’t have side effects that were not found in time!

Cardiovascular and cerebrovascular diseases have become the number one killer endangering our lives and health. Preventing and treating cardiovascular and cerebrovascular diseases is almost related to every family, because the number of cardiovascular diseases in China has reached 330 million at present, including 11 million coronary heart disease and 13 million stroke, so each of us is more or less inextricably linked with cardiovascular and cerebrovascular diseases.

Statins, as the cornerstone drugs for the prevention and treatment of cardiovascular and cerebrovascular diseases, have attracted more and more attention. On the one hand, statins can bring benefits to more patients, on the other hand, the side effects of statins must be paid enough attention.

As a representative of the third generation statins, rosuvastatin is gradually known by people.

Rosuvastatin is a lipid-regulating drug and an inhibitor of 3- hydroxy -3-methylglutaryl-CoA (HMG-CoA) reductase. Rosuvastatin can inhibit cholesterol synthesis and reduce blood lipid level, especially low-density lipoprotein. Rosuvastatin has the effects of stabilizing plaque, anti-inflammation and improving endothelial function, and it is one of the long-term drugs for patients with coronary heart disease and stroke.

In short, what benefits can rosuvastatin bring to us?

Reduce cholesterol, low density lipoprotein and triglyceride; At the same time, it can increase high density lipoprotein. Rosuvastatin also has the function of preventing and treating cardiovascular and cerebrovascular diseases.

Friends who take rosuvastatin for a long time are nothing more than dyslipidemia or to prevent and treat cardiovascular and cerebrovascular diseases. Moreover, patients with abnormal cholesterol or cardiovascular and cerebrovascular diseases generally need to take statins for a long time, because even if statins can reduce cholesterol and return to normal, once they stop taking drugs, their blood lipids will be abnormal again; Just like taking antihypertensive drugs for a long time for hypertension and taking hypoglycemic drugs for a long time for diabetes.

Of course, the emphasis is on coronary heart disease, cerebral infarction and other diseases. Even if blood lipids are normal, statins should be taken for a long time, because it is mentioned above that statins are not only lipid-regulating drugs, but also drugs that stabilize plaques, resist inflammation and improve endothelial function, which can effectively prevent and reduce the risk of cardiovascular and cerebrovascular diseases.

All drugs that need to be taken for a long time are the most troublesome thing for people. Once side effects occur, not only will their diseases not be cured, but they will increase their heart diseases. It is really impossible to catch chickens and eat rice.

Therefore, every time Dr. Wang prescribed rosuvastatin to a patient, he must repeatedly explain what are the side effects of rosuvastatin. What should I pay attention to?

Take rosuvastatin need to pay attention to:

1. If it is not for emergency use before taking it, it is best to check a liver function, four blood lipids, blood sugar and muscle enzymes.

2. Take liver function, blood lipid, blood sugar and muscle enzyme within 3 months.

A, if the transaminase is 3 times higher than the normal value, you should stop using this product or reduce it, because rosuvastatin will cause liver damage, which will lead to the increase of transaminase, especially in the first three months.

B. Attention should also be paid to the increase of muscle enzyme. It is generally suggested that the muscle enzyme should be stopped when it is increased by 10 times. However, once the muscle enzyme is found to be increased in clinic, we dare not wait until it is increased by 10 times, so we will stop taking the drug as soon as possible and observe. Stop using this product immediately when myalgia and myasthenia occur for unknown reasons or suspected myopathy, and check the muscle enzymes as soon as possible. Because statins cause muscle damage is a common side effect.

C, if blood sugar rises, it may be that statins are at work, but we can’t stop taking drugs just because rosuvastatin may cause new-onset diabetes. Statins themselves bring us more benefits than new-onset diabetes. Simply understanding statins to prevent 9 cardiovascular and cerebrovascular diseases may lead to 1 diabetes, and if we find that active control of diabetes can also reduce the risk caused by diabetes.

3. It may also occur: pharyngitis, pain, headache, flu-like syndrome, etc.

4. If there is no problem after the review in the first three months, it is recommended to review it once a year in the future.

Who uses it with caution?

Excessive drinkers should use it with caution; Use with caution in patients with a history of liver disease; Use with caution for lactating women.

Who is forbidden?

Statin allergy, active liver disease, myopathy, pregnant women.

Rosuvastatin can indeed bring us many benefits, such as adjusting blood lipids, reducing bad blood lipids, raising good blood lipids, reducing the occurrence of cardiovascular and cerebrovascular diseases, and preventing myocardial infarction and cerebral infarction; But any drug is a double-edged sword. If it is used well, it will help people, but if it is not used well, it will harm people.

Monitoring the side effects of rosuvastatin is very important for friends who take rosuvastatin!

shell of nuts

The following article comes from Guoke Children’s Academy, written by Xiao Tian.

In recent days, the epidemic situation in COVID-19 has been raging. At present, the number of new cases is still rising, and the cumulative number of confirmed cases has exceeded 70,000. The situation is still very grim.

Although there have been many articles on popular science home disinfection, there are still many people who are not at ease and often come to ask, is this disinfection effective? Can you kill Covid-19?

This article pushed by Nut Mom today, starting from the mechanism of disinfectant, makes you clear about the inactivation process of get virus, and at the same time, you are no longer anxious and calm!

one

Structural characteristics of Covid-19.

Novel coronavirus, which caused the pneumonia epidemic, has been identified as an enveloped virus. Besides the capsid formed by protein and its genetic material (single-stranded RNA), it also has an envelope.

Schematic diagram of Covid-19 structure

On the surface of the envelope structure, there are three kinds of glycoproteins, namely:

Spike glycoprotein (S, SpikeProtein, receptor binding site, cytolysis and major antigen site)

Small envelope glycoprotein (e, EnvelopeProtein).

Membrane glycoprotein (M, MembraneProtein, responsible for transmembrane transport of nutrients, budding release of newborn virus and formation of virus envelope)

Covid-19 electron micrograph

If disinfectants, or other environmental conditions, can destroy the structure of Covid-19, it should be able to effectively inactivate it.

2

The Mechanism of Common disinfection products

At present, disinfection products on the market can be classified according to the site of action, which can be summarized into the following two categories:

Nucleic acid directly acting on internal genetic material: ultraviolet disinfection

Protein is inactivated by most chemical disinfectants and high temperature.

The deactivation of protein mainly changes and destroys its secondary or tertiary structure by heating, dehydration, oxidation, salification, deamination and charge change.

three

How to choose an effective disinfection products?

one

Direct destruction of RNA

Representative products: ultraviolet lamp, ultraviolet disinfection cabinet.

Common disinfection lamp products

Ultraviolet is an electromagnetic wave, which can be generally divided into:

UVA (ultraviolet a, wavelength 320 ~ 400 nm, long wave)

UVB (wavelength 280 ~ 320 nm, medium wave)

UVC (wavelength 100 ~ 280 nm, short wave)

It should be pointed out that the wavelength below 200nm is vacuum ultraviolet, which can be absorbed by air. Therefore, the wavelength that UVC can pass through the atmosphere is between 200 ~ 280 nm, which is also the wavelength band selected by UV lamps in the market at present. Among them, the sterilization effect is the strongest at 253.7nm.

After Covid-19 is irradiated with UVC, it can undergo photochemical reaction with its genetic material RNA, causing the cleavage of phosphodiester bond and hydrogen bond, forming pyrimidine dimer (such as uracil cyclobutane dimer, uracil hydrate, cytosine hydrate, etc.), thus causing the virus to lose its replication ability.

Ultraviolet lamp disinfection, although effective, is not recommended.

matters need attention

Purchase ultraviolet lamps with 253.7 nm wavelength for disinfection and sterilization (different from decorative ultraviolet lamps, etc.);

Ultraviolet ray penetration is poor, so it should be directly irradiated on the surface of the object during sterilization and disinfection, and the distance from the irradiated object should not exceed 1 meter.

When disinfecting indoors, doors and windows should be closed, and personnel should avoid it. The irradiation time should be not less than half an hour, and after disinfection, it should be fully ventilated.

Ultraviolet rays can damage the skin and cornea, so people should not directly touch or stare, especially children.

2

Destroy protein and inactivate it.

01

Physical heating

Representative products: steam disinfection cabinet/pot/machine, etc.

Common steam boiler

This kind of products use the high temperature of water vapor to break the disulfide bonds and hydrogen bonds in the protein molecule of the virus to destroy its secondary structure; Peptide bonds will also break after a long time.

In this way, protein will change from a regular spiral, spherical and other spatial structures to an irregular extended peptide chain, resulting in irreversible inactivation.

This kind of products are mainly aimed at some heat-resistant items, such as tableware, toys, baby bottles and other small items. It is not recommended to buy it. Boil it directly in a pot or steam it in a steamer, and the same effect can be achieved.

It should be noted that for Covid-19, the temperature should be at least 56℃, and the disinfection time should be at least half an hour to ensure that the virus is fully inactivated.

02

dehydrate

Representative products: medical alcohol

Ethanol (commonly known as alcohol) can kill viruses with envelope structure, so it is effective for Covid-19 this time.

Specifically, alcohol has a certain fat solubility, and according to the principle of "similar compatibility", it can destroy the lipid envelope composed of phospholipid bilayer; At the same time, protein can be dehydrated and denatured when it comes into contact with glycoprotein on the surface of virus envelope, thus inactivating the virus.

It should be emphasized that the reason why 75% alcohol is used is that when the alcohol concentration is too high, the dehydration reaction will be too fast, which will cause the protein in contact to condense rapidly, thus forming a protective dura mater on the surface of the virus to prevent further infiltration of alcohol. When the concentration is too low, it is not enough to kill the virus.

At the concentration of about 75%, the antivirus effect is the best. Alcohol will dissolve the protein envelope first, and then penetrate into the virus a little bit to degrade the genetic material.

The concentration of medical alcohol in the market is mostly 95% and 75%, and the latter has better disinfection effect. If it is the former, it can be diluted with water (100 ml of 95% alcohol and 27 ml of distilled water) to make about 75% alcohol.

If you can’t buy medical alcohol, more than 75% liquor can also be used to disinfect the surface of objects, but because there are other substances besides ethanol, the effect is definitely not as good as medical alcohol. This is an emergency measure and is not recommended for long-term use.

When in use, the alcohol solution can be sprayed in a watering can, or it can be wiped with an alcohol cotton ball made of cotton swabs. Hands, mobile phones, remote controllers, door handles, buttons, keys, keyboards and mice can all be disinfected with it.

matters need attention

Don’t spray alcohol on infants, avoid touching a lot of alcohol on the body, and prevent allergies or alcoholism;

When using alcohol, don’t be close to the heat source, and don’t spray directly into the air to avoid fire;

Do not spray alcohol on clothes to prevent static electricity from causing fire;

When disinfecting the surface of electrical appliances, remember to cut off the power supply, and all items should be reused after the alcohol volatilizes;

Alcohol should be stored in a dark, cool and ventilated place to avoid children’s contact.

03

oxidate

Representative product 1: chlorine-containing disinfectant

All chlorine-containing disinfectants have one thing in common-they can generate hypochlorous acid (HClO) with microbicidal activity after being dissolved in water.

Hypochloric acid has a small molecular weight and strong oxidizing property. When it comes into contact with Covid-19, it will first oxidize the envelope protein to denature it, and at the same time damage its protein shell, so that its protein cross-linking function will be lost, thus further destroying the biological enzyme system and genetic genes and making it inactive.

Common chlorine-containing disinfectants in the market include bleach, bleach, 84 disinfectant, etc., which can be used for household daily necessities (such as tables and chairs, bedside tables, sanitary ware, door and window handles, etc.). It should be pointed out that not all disinfection products with the word "chlorine" are chlorine-containing disinfectants.

Although the main components of this chlorine-containing disinfectant are different, here is a trick for everyone: the main components of the product are "sodium hypochlorite" or "calcium hypochlorite", that is, chlorine-containing disinfectant (of course, the main components of chlorine-containing disinfectant also include hypochlorous acid, trisodium phosphate chloride, sodium dichloroisocyanurate, trichloroisocyanuric acid, chloramine, etc., but the first two are commonly used in household products).

When using, some solid disinfectants (such as bleaching powder) need to be prepared into a solution with a specified concentration for use; Liquid disinfectants (such as 84 disinfectant) need to be diluted with water in a certain proportion before use. Just follow the instructions.

matters need attention

Chlorine-containing disinfectants are generally irritating to some extent, so masks and gloves should be worn and protected when configuring and repackaging;

Chlorine-containing disinfectants are highly oxidizing, so they should be stored away from high temperature, fire sources and children.

Chlorine-containing disinfectants should avoid contact with metal objects and colored clothes to avoid corrosion or fading;

In particular, it should be noted that chlorine-containing disinfectants should not be used with alcohol or toilet cleaner at the same time, which will produce toxic gases and cause harm to human body.

Representative product 2: peroxide disinfectant

Peroxide disinfectant refers to a kind of disinfectant which contains divalent peroxy group "-O-O-" in its molecular structure and can produce active oxygen with bactericidal ability, and the representative is peracetic acid.

It also kills Covid-19 because of its strong oxidizing ability. When exposed to the virus, it can be damaged by removing the electrons of the virus envelope protein, and it can also attack the nucleotide base and sugar-phosphate skeleton, thus destroying the biological structure and function of the virus.

Besides peracetic acid, peroxide disinfectants also include hydrogen peroxide (hydrogen peroxide) and chlorine dioxide.

This is a kind of safe and green disinfectant. Among them, the products containing peracetic acid have the pungent smell of acetic acid, which are mostly used for industrial and agricultural disinfection, and are generally not recommended for household use. Hydrogen peroxide is very suitable for home use, and can be used on tables, nightstands, sanitary ware, door and window handles, stair handrails and other surfaces.

When in use, according to the national standard GB26371-2010 hygienic standard for peroxide disinfectants, "on the surface of general objects, use 0.1% ~ 0.2% peracetic acid or 3.0% hydrogen peroxide for disinfection for 30 minutes, and then rinse with clear water to remove residual disinfectants", or operate according to the product instructions.

matters need attention

Peroxide disinfectants are highly oxidizing and irritating to skin and mucosa, so be careful not to let children touch them.

Peroxide disinfectants should be stored in a ventilated and cool place to avoid high temperature and metal to prevent explosion danger;

Hydrogen peroxide is unstable, and its disinfection ability will fail if it is stored for a long time. Therefore, it is recommended to store it in the dark and seal it tightly, and use it as soon as possible after opening.

It is worth mentioning that disinfection products (such as Di Lu, Verus, etc.) whose main component is "p-chloroxylenol" is controversial at present.

Dew disinfectant

P-Chloro-m-xylenol (PCMX for short) belongs to phenolic disinfectant, and there are few reports on its action on coronavirus. According to the experimental results in recent years, this kind of disinfectant is effective for SARS-CoV SARS virus, human coronavirus 229E and MHV coronavirus.

In view of the high homology between Covid-19 and SRAS virus, we infer that the disinfectant containing p-chloroxylenol may have a killing effect on novel coronavirus.

The best effective concentration of p-chloro-m-xylenol is 0.12%, and the specific products can be used according to the instructions or diluted with water.

Another one that is discussed more is the ozone machine.

Ozone machine, picture from Amazon.

In terms of mechanism, the strong oxidation of ozone is effective for viruses. Previously, there have been experimental reports on the inactivation of SARS virus by active oxygen and ozone, and a high inactivation efficiency has been achieved.

However, ozone is highly irritating, unstable in chemical properties, harmful to human body due to poor dose control, and the official has not given a clear conclusion at present, so it still needs to be used as a home disinfection method as appropriate.

That’s the summary of all the effective disinfection products for Covid-19. In view of the current outbreak of pneumonia, experts from the Health and Health Commission pointed out: "Disinfection is an important means to cut off the route of transmission and control the epidemic of infectious diseases."

I hope everyone will do a good job in home protection and scientific disinfection, so that the virus has no chance.

Core tips

"Three Ties and Three Worlds, visit Anxi."

Behind this hardcore cultural tourism brand, there are three world-class gold-lettered business cards: Tieguanyin, the world’s important agricultural cultural heritage and the intangible cultural heritage of mankind; Rattan technology, the only "rattan technology capital of the world" in the world; Smelting Iron, Qingyang Xiacaopu Iron Smelting Site is one of the 22 World Heritage Sites of "Quanzhou: the World Ocean Trade Center of China in Song and Yuan Dynasties".

In addition to gold-lettered signboards and gold-lettered business cards, Anxi has more-in the thick tea fragrance, this land is harmonious with nature and humanity, beautiful scenery, attractive food and fireworks, and material and intangible cultural heritage complement each other. Based on these unique resource advantages, in recent years, Anxi has actively promoted the deep integration of tea, culture and tourism, and the close and good interaction between the "three railways", and embarked on a new path of high-quality development of the cultural tourism economy in the county.

Pay attention to rewards

Melt out new wonderful "volumes" to new heights.

Anxi is rich in cultural tourism resources.

As the birthplace of Tieguanyin, there are beautiful scenery, fragrant tea fruits, 41 tea estates embedded in it, and three world-class cultural heritage business cards; Continue the context of the ancient county with a thousand years, where the cultural heritage is profound and the cultural heritage and intangible cultural heritage are scattered all over the place; Adhering to the humanistic spirit of "relying on one’s own bones to grow meat", it ranks among the top 100 counties in China from a national poverty-stricken county, with distinctive urban characteristics. The rapid development of industries in various fields, including tea industry, has also deeply accumulated the confidence of "ecological tourism" and "industrial tourism" for Anxi.

"The advantages of cultural tourism resources are not equal to the advantages of high-quality development of cultural tourism. We use lines and products as a bridge to promote the transformation of the two. " Cai Yajuan, director of Anxi County Cultural and Sports Tourism Bureau, introduced that last year, the bureau actively integrated the specialties, good things, scenery and industries of Anxi County, and launched four theme tourism products, namely, "Pinming Manor, Tea Rhyme Mountains and Seas", "Hot Spring Water Heating, Healthy Mountain and Seas", "Industrial Sightseeing, Smart Mountain and Seas" and "Tasting with the Tip of the Tongue". The market response was enthusiastic. Grasping the two routes of "Three Tiers and Three World Heritage" and Tea Travel, it has been well received by the industry. Among them, the trip of "Three Ties and Three Worlds, Enjoying the Life of Tea Fragrance" was awarded as the national tea town tourism boutique route in 2023, and the trip of "Haisi Tea Source Tea Tourism Resort" was selected as the national rural tourism boutique route in 2023.

The promotion of transformation consciousness, the cultivation of line products and the warming of response are behind the Anxi county party Committee and county government putting the development of cultural tourism economy on a more important agenda.

Last year, Anxi successively issued heavyweight documents such as the "Cultural Travel+"special action, the work plan for promoting the construction of national cultural and tourism consumption pilot cities, and the support and reward measures for promoting the integration, innovation and development of cultural tourism economy and industry, and set up a special working group to implement five major actions such as "upgrading the energy level of cultural tourism industry". Under the framework of this policy package, Anxi proposed to leverage the brand radiation influence of "China Haisi Quanzhou in Song and Yuan Dynasties" to highlight the cultural charm of Anxi’s "Three Ties and Three World Heritage", promote the deep integration and development of culture and tourism industry, and improve the quality and efficiency of cultural tourism consumption. To this end, the county finance budget is more than 15 million yuan per year, which is used for awards in the fields of brand creation, planning and preparation of cultural tourism, introduction of cultural tourism sources, exhibition marketing of cultural tourism festivals, creation of characteristic homestay tea manor, development and marketing of tourism gifts, development and marketing of tourism food, and improvement of cultural tourism facilities and services.

Under the attention and rewards, the brave man also achieved results. Take cultural tourism festivals and exhibitions as an example. In the past year, the activities of promoting cultural tourism and promoting consumption by "Xi Shi You Wei", Quanzhou Mountain Ecology (Anxi Tea Manor) Tourism Festival, Anxi Wenchuang Tourism Commodity Competition, Anxi Tourism and Food Life Festival, Anxi Tea Festival, and Anxi Spring Festival theme activities of "Searching for Dragons" were spectacular. Only before and after the Spring Festival in the Year of the Loong, nearly 100 cultural tourism theme activities were launched in Anxi for two months, which melted new splendor on the road of deep integration of cultural tourism, and scored new heights for Anxi, Quanzhou and Fujian cultural tourism.

Innovation and creativity

Cultivate the format and invigorate the market.

Innovation is productivity, and so is the field of economy. Anxi, which is led by innovation and creativity, has made full efforts to develop the six elements of "eating, living, traveling, buying and entertaining" in the integration of tea and cultural tourism, which is refreshing and "stirring a pool of spring water" in the cultural tourism market.

Eat, a table of "Xiangfu Family Banquet", fragrant and floating in the dining hall of Peking University. At the beginning of April, in Xinyuan canteen of Peking University Xinyanyuan Campus, Hutou snack, a part of the "Xiangfu Family Banquet", was widely praised and enthusiastically sought after by teachers and students. This delicious food lesson made teachers and students from Anxi and Fujian more attached to their hometown, and also made teachers and students from Peking University know about Anxi and get to know Anxi.

Eating is becoming more and more important in people’s travel nowadays. Many young people describe tourism as "eating and eating", which shows that eating, like shopping, is an important way to appreciate the unique local culture. Based on this understanding, Anxi developed and launched a "Xiangfu Family Banquet" with a table of dishes in one county, and held many food consumption and selection activities such as "Picking up in Huaxi and Picking up Taste in the Stream" 2023 Anxi Tourism and Food Life Festival. With great efforts, the "Xiangfu Family Banquet" became famous gradually, and six catering enterprises were selected as the "New Fujian Cuisine, the Most Southern Fujian" Quanzhou famous food stores and popular famous stores, in order to attract tourists to Anxi, "a wave of special catering points" was given.

Live, to explore and innovate and constantly enrich the choices, especially to provide citizens and tourists with an accommodation experience with the characteristics of tea country. Gande Town launched the first high-speed homestay in Fujian Province. In Guoxin Green Valley Tea Manor, B&B guests can find the pleasure of returning to the countryside from valleys, bamboo forests, sea of clouds and tea mountains during the day, and they can also watch the stars through the glass roof at night and go to a romantic appointment in the good ecology of the landscape tea village. Up to now, Anxi County has completed the upgrading of 29 "tea-scented homes" homestays.

Ok, to adapt to slow-paced travel, Anxi has opened six bus lines leading to scenic spots, and also completed the upgrading of parking lots in some scenic spots such as Fengshan.

Traveling, introducing technology and implanting AR technology in scenic spots have become a "sharp weapon" to attract young people. In Qingshuiyan Scenic Area, visitors only need to scan the QR code through their mobile phones and install small programs to experience the interaction. In addition, there are still many attempts to empower cultural tourism with the digital platform of "Anxi Tourism" and the album page of "Anxi Cultural Tourism Experience Hall" of Ctrip.

Buy, tea and the world, Anxi polite. In the first half of last year, Anxi released the first batch of 41 cultural and creative products in 10 series, covering cultural characteristics such as Anxi tea, rattan iron, faith and customs, and opera. At the end of last year, 52 tourist commodities were collected in the county, and online selection was carried out to vote for the most popular Anxi tourism gift.

Entertainment, named after the varieties and brands of tea trees, combines Anxi Gaojia Opera, Tieguanyin tea art, original ecological tea songs, Nanyin and other intangible heritages, and newly created stage drama Tieguanyin is a large-scale theme series sitcom of tea culture; Tieguanyin Men’s Team, with its "top flow" and tea songs and dances reflecting Tieguanyin’s unique wrapping skills, attracted warm applause every time it appeared.

"In fact, we not only focus on the six elements and single point, but also attach importance to cross-domain integration and innovation." For example, Cai Yajuan said that today’s Anxi, "sightseeing+culture", tea manor has become a tourist attraction; "Art+tourism", tea culture has become a tourist performance, "industry+tourism", tea factory has become a tourist factory; "Teahouse+Food", the night market has become a tea culture leisure block; "Tea+leisure", tea shops have become teahouses and teahouses; "Tea Master+Folk Custom", the ancient building has become a tourist homestay, and the endless new formats have brought full vitality. Now everyone’s new understanding of Anxi Tea Travel is delicious, delicious, fun, beautiful, easy to live, and easy to take away.

In the Internet era, online celebrity’s economy is reshaping the consumer market more and more profoundly. Facing up to the new trend of the development of this network era, Anxi braved the wind and waves, bravely stood at the forefront, and with a youthful move, grabbed the traffic and refused to admit defeat, promoting the "good wine" of Anxi Tea Travel, stepping out of the mountains, going to the country and going to the world.

"The most beautiful April day on earth, enjoy the cuckoo on Foer Mountain". On April 11th, Foer Mountain Buddha Tianyan in Xianghua Township, Anxi, amid the bright red of new green and azaleas, Gaojia opera, She costume show, Xianghua cook’s food promotion, healthy mountaineering and other scenes appeared in turn. Through the pictures and texts of media reporters and short videos of bloggers, they appeared on newspaper screens and social platforms, bringing heat and passenger flow to this "Inner Anxi" tea-scented town.

Xianghua’s spring marketing is the spontaneous initiative of villages and towns, and it is also a habit formed under the atmosphere that the county attaches importance to marketing. Event and event marketing, Anxi keeps walking-

County leaders set an example by themselves. From June to September, 2023, "Feng Ming Yu Xi-Anxi Historical and Cultural Exhibition" was exhibited in China National Museum. Wu Yuzhou, secretary of Anxi County Party Committee, also went to Guobo Lecture Hall to give a lecture on the theme of "A Talk on Anxi’s History and Culture" to promote and promote a thick, rich and flesh-and-blood Anxi. "Northeast old irons, I’d like you to meet a friend from Anxi, Fujian, also called" old irons ",whose name is" Tieguanyin ". This year, in the Year of the Loong, the Northeast Old Tiers also came to see the dragon in Anxi, the oolong in southern Fujian. " Harbin Fire Out of the Circle, Liu Yongqiang, the county magistrate of Anxi County, made an invitation to speak for Anxi Tea Travel through a short video. Inside and outside the province, at the scene of various tea and cultural tourism activities in Anxi County, there is always a deputy magistrate Lu Rongbin platform and promotion figure.

Non-legacy flash into the ancient city. On the eve of the Spring Festival, many activities such as Anxi Opera Song and Dance, Tea Song te amo, Gaojia Opera, the distribution of special cultural and creative products, and the exhibition of intangible cultural heritage of blue printed cloth gathered a sea of onlookers in the downtown area, which quickly filled the popularity and goodwill.

The non-legacy team went to Beijing. At the end of March, the cultural brigade of "Xi Shi You Wei" presented an intangible feast in the Forbidden City, Peking University and other places, including Tieguanyin and Hutou snacks tasting, Gaojia opera and tea song te amo performance. The Gaojia opera "Li Guangdi" was performed in Mei Lanfang Grand Theatre, which set off a wave of Anxi voices among the people and tourists in the capital.

With tea as the medium, around the "International Tea Day" on May 21 last year, the cultural exchange seminar and tasting promotion activities of "Tea and the World" and Yaji, which were mainly participated by Anxi, were held at the United Nations Headquarters in new york, USA. Ambassadors of various countries who were dumped by Oriental Jiaming took the initiative to announce some praises on social media.

Anxi also regards publicity and marketing as an "amplifier" of effects, and the traditional mainstream media, social platforms and self-owned media keep pace. In the past year, Anxi has opened a short video platform account, and the WeChat WeChat official account of Anxi County Cultural and Sports Tourism Bureau has repeatedly entered the top 10 of the monthly communication index of new media in cultural tourism in counties (cities, districts) of Fujian Province.

At the same time, Anxi is also thinking about such a profound topic with Quanzhou and the province-how to make the flow become "reserved", "online celebrity" become "long red" and attract more attention. With the project as the backbone, investment promotion as the stamina and talent team as the support, Anxi will look to the longer term.

The reporter was informed that Anxi exceeded its annual investment plan for key projects last year. This year, two cultural landmarks will be completed and put into use. Among them, Fengshan Academy (cultural center, museum, library) is included in this year’s "Project Excellence Year" completed project, which is expected to be put into use by the end of this year and will become a new landmark for the integration of cultural tourism in Anxi. The Opera Center is expected to be completed and accepted in May, and it will become the main position of Anxi traditional opera, drama, song and dance drama and other exhibitions, literary creation, and cultural travel performances, further enriching the night cultural travel life of the masses and tourists.

Attracting investment, last year, 37 cultural tourism projects were collected in the county, and the cultural tourism investment manual was compiled. There were 9 "going out" investment promotion activities throughout the year, and 34 cultural tourism economic projects were signed in the county with a total investment of 17.192 billion yuan. This year, we will strive to make new breakthroughs in the fields of "cultural tourism+"such as digital cultural creation, leisure and recreation, and film and television performing arts.

Talent echelon, has absorbed 14 cultural travel experts to form Anxi cultural travel think tank.

In 2024, Anxi put forward the high-quality development of cultural tourism economy, and will implement the special action of "upgrading cultural tourism", which will be deeply integrated into the overall situation of "Haisi starting point is fresh in Fujian" and "China Haisi Quanzhou in Song and Yuan Dynasties", so as to create a new glory in the deep integration and development of tea cultural tourism.

At the same time, the initial value of the annualized quarterly rate of the core PCE price index in the first quarter recorded 3.7%, the highest since Q2 last year. As a result, traders delayed the Fed’s expectation of the first rate cut until December. Goolsbee said that the Fed must readjust its policy after the high inflation data.

The company also paid a quarterly dividend for the first time in history and will buy back up to $70 billion in additional shares.

　　AI helped Microsoft’s first-quarter earnings report exceed expectations across the board, and cloud revenue once rose by more than 5% after the accelerated growth.

　　　　　　 CCTV News:The General Administration of Market Supervision issued an announcement last night (18th). In response to media reports that pork products such as dumplings were positive for African swine fever virus nucleic acid, the General Administration of Market Supervision and the Ministry of Agriculture and Rural Affairs have asked enterprises to immediately trace the source of pork raw materials and dispose of pork products. At present, the two departments have sent a joint inspection team to investigate and verify the relevant situation, requiring pork products manufacturers to further strengthen the control of pork raw materials, implement the inspection and quarantine ticket inspection regulations, improve the African swine fever detection and review system, and prevent infected pork raw materials from entering the food processing link. Enterprises that fail to fulfill their prevention and control responsibilities as required will be severely punished once they are found.

　　　　　　 Sanquan Food: Suspected batch products have been sealed.

　　　　　　 In this incident, it was revealed that several batches of soup dumplings produced in Sanquan Food were suspected of African swine fever virus. In this regard, Sanquan Food announced yesterday (18th) that the company had sealed all relevant suspected batches of products from all sales channels for the first time. At the same time, the Henan provincial government has sent a joint investigation team to Hunan and Gansu respectively to check the relevant situation with relevant local departments.

　　　　　　 Expert: There are four possibilities for quick-frozen food to be infected with virus.

　　　　　　 After the incident was exposed, netizens raised some questions, such as: How did African swine fever virus flow into frozen food? In this regard, a reporter from Voice of China interviewed Yi Zhu, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University. Yi Zhu pointed out that the most extreme situation is that sick and dead pork is mixed into the production process. In addition, there are three possibilities.

　　　　　　 Yi Zhu, Associate Professor of College of Food Science and Nutritional Engineering, China Agricultural University, said: "The first reason is that the detection methods have been greatly improved and the detection sensitivity is very high. Even if there are only a few viruses, it can be detected. The second reason is that when pork was imported and slaughtered, some pigs with latent disease were not identified. It has been carrying African swine fever virus, the incubation period is about 5 to 19 days, and there is no disease. If you don’t do special disease detection, you can’t see it with the naked eye, so that such pork is mixed into the supplied products. The third reason is that there is no problem with pork itself, but it is polluted by African swine fever virus in transportation, processing and packaging. "

　　　　　　 Expert: It will not infect people and will not affect food safety.

　　　　　　 Another question that everyone cares about is, is African swine fever virus harmful to human body? Can pork still be eaten?

　　　　　　 Experts from the Ministry of Agriculture and Rural Affairs have responded to this repeatedly mentioned question. African swine fever is not zoonotic and will not infect people. At the same time, it will not infect other animals except pigs and will not affect food safety. In addition, experts also said that high temperature can kill African swine fever virus, and continuous heating at 60 degrees Celsius for 20 minutes can kill the virus. Therefore, everyone can safely consume the quarantined pork.

　　　　　　 However, is African swine fever virus harmless to human body? In an interview with Yi Zhu, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, Yi Zhu said that although African swine fever virus does not pose a health risk to people, pigs with African swine fever belong to sick pigs, and there is no reason to walk on the shelves and dining tables.

　　　　　　 What is African swine fever? It was diagnosed in Africa in 1921 and ravaged many countries in 2018.

　　　　　　 African swine fever is an acute and severe infectious disease of pigs infected by African swine fever virus. It was first diagnosed in Kenya in 1921, and it raged in many countries around the world in 2018. More than 6,200 outbreaks were reported in 22 countries. In August 2018, the first African swine fever epidemic occurred in Shenbei New District, Shenyang, Liaoning Province. Subsequently, epidemics also occurred in Zhengzhou, Henan Province, Lianyungang, Jiangsu Province, and Wenzhou, Zhejiang Province.

　　　　　　 According to the survey, there are three main transmission routes of African swine fever in China: the transportation of pigs and their products in different places, the feeding of kitchen waste to pigs and the spread of viruses carried by people and vehicles, accounting for 16.3%, 42.9% and 40.8% respectively. Among them, the spread of viruses carried by kitchen waste feeding pigs and personnel vehicles accounts for the vast majority.

　　　　　　 In January this year, the Ministry of Agriculture and Rural Affairs formulated and issued the "Emergency Implementation Plan for African Classical Swine Fever Epidemic (2019 Edition)" to guide all localities to deal with the epidemic in a strict and standardized manner. The Ministry of Agriculture and Rural Affairs said that the current epidemic situation in China is in a state of sporadic distribution, and the epidemic situation is generally controllable. However, because the traditional farming structure is difficult to fundamentally change in a short period of time, the transmission route of the epidemic is complicated, and the prevention and control situation is still complicated and severe.

Every morning and evening rush hour or weekend, the surrounding area of Chaoyang Joy City is always full of traffic. The residential areas and office buildings here are connected together, gathering a large number of fashion brands and creative restaurants, which is not only the punching place for trendy people and foodies in Beijing, but also the regional "base camp" for takeaway brothers.

One by one, waiting beside the electric take-away cars on the roadside, the riders who have taken orders are in a hurry. They go in and out of various restaurants, and the lunch boxes in their hands may be freshly baked restaurant specialties, coffee, ice cream or midnight snack.

Chaoyang Joy City is just a microcosm of the take-away market. According to the report of iResearch, there are more and more young people and office workers in China who are willing to spend money on convenience. After five years, the online penetration rate of food consumption will reach 29.5%, which is about 14.1 trillion yuan.

Behind the busy riders is the protracted battlefield of the giants. After numerous melee, killing and subsidy wars, this year, Meituan Dianping finally went public as the world’s largest food and beverage delivery service provider and the largest in-store food and beverage service platform in China. However, Ali was hungry after integration, and Enemy at the Gates.

This year, in order to achieve the goal of gaining 50% share of the take-away market, Ali took out nearly three times the subsidy of the US delegation, and claimed that there was no upper limit for the recruitment of riders.

The ultimate battle around "eating" is underway. In addition to the first-tier cities such as Beishangguangshen and Shenzhen, the war is about to spread to more cities and counties in Ali and Meituan.

In the new retail industry logistics system that pursues efficiency and speed, the rider is the most basic element, and it is also an important link in the increasingly refined life industry chain. In the world of short video, riders, as individuals with emotions, are like detectors, reflecting the changes of the whole market, the vibration of industry and the transformation of society.

From factory to takeaway

Every year, Meituan Review publishes an "Annual Report on Takeaway Development". In the report, the daily average number of active distribution riders of the US Mission increased from 100,000 in 2015 to 531,000 in 2017.

According to the statistics of "Research Report on Takeaway Riders in 2018", 75% of riders come from rural areas, and nearly 70% of riders choose to leave their hometown to work hard in other places and struggle in first-and second-tier cities. Moreover, young people after 1980s and 1990s account for 82% of the riders.

In just three years, take-away riders have changed from marginal jobs to "reliable" jobs for young rural laborers in cities. The comments of the US delegation and Hungry have created more than one million jobs, and the work of "Lingzhi Xiaoxiao" belongs to this "one in a million".

At the beginning of this year, a 21-year-old Dong girl came to Hangzhou from her hometown of Yunnan. A friend introduced her to work in a clothing factory where many fellow villagers worked. In a workshop full of girls, she kept cutting clothes and car lines from morning till night. The first month’s salary was 2,800 yuan, the second month was 2,500 yuan, and the third month found that the salary was too low. She only worked for half a month and resigned after taking 1,500 yuan.

Later, she went to work in a restaurant. I heard from a familiar rider that Meituan crowdsourced her working hours flexibly and made more money, so she wanted to try it part-time. Unexpectedly, she found a sense of belonging in this man’s industry.

"When I arrived at the US Mission, I felt that I had been mixed up before." Novel, in the past, in the clothing factory, peers always wanted to eat, wear and play. After becoming a rider, I saw that my fellow riders were racing against time to make money, and the realistic pressure of "getting married and saving money" made her mature at once.

Unlike the assembly line in the factory, the rider needs a strong "motive force". Because part-time riders have no basic salary and earn as much as they do, the real-time income of sending a few dollars makes her very economical and punctual. Short stories, those riders who earn more than 10,000 yuan a month are very hard-working, running for 15 hours every day, and often finishing work at 3 or 4 in the morning. These role models make her even reluctant to talk about her boyfriend, because time is too precious and she is afraid it will cost too much money.

Xiaoxiao also found himself "more and more tough." I remember that in the first week as a rider, the delivery road was bumpy at 11 o’clock at night. Some soup spilled on the bag, and the customer looked ugly and slammed the door. She cried sadly, thinking about "bad reviews" and "I didn’t mean to". At that time, she took a video to record an unfortunate day. As a result, fans in Aauto Quicker left messages to cheer her up, and riders left messages to teach her how to deliver a soup meal and how to appease unhappy customers.

However, Xiaoxiao is afraid to tell her family that she is running a takeaway, because a little girl who works as a rider always makes people worry. She said that if there is no income from live broadcast on Aauto Quicker, she will often deliver meals until the early hours of the morning, which is the normal state of crowdsourcing riders.

In the past six months as a rider, Xiaoxiao recorded the ups and downs of being alone in a foreign land on Aauto Quicker in the form of short video, which is also her way to fight loneliness and pressure. She said that although there are only 14,000 fans, chatting with them live every night after work, and the fatigue and grievances of work have vanished.

Although she is not as stable as her fellow villagers, Xiaoxiao is not very satisfied with her job. She can earn four or five thousand yuan by delivering food every month, and her income is several times that of a girl from her hometown.

As shown in the World Development Report 2019: Changes in the Nature of Work released by the World Bank, technological progress has accelerated the growth of platform enterprises, and is also changing the way people work, creating more non-traditional jobs and short-term "odd jobs". From the small description, we can intuitively feel that the young labor force is shifting from the traditional agricultural and manufacturing fields to the service industry, and correspondingly, it will also accelerate the rapid development of local life business.

From the third and fourth lines to the first and second lines.

In July this year, Hungry announced that it had invested RMB 3 billion in the "Summer Campaign", and what this data shows is the way to attract cooperative large, medium and small businesses and riders and incite the take-away market.

Abo can list the policies such as unit price, rewards and subsidies for the US delegation and the hungry riders. He has experienced them from the US delegation to the hungry, from the first-tier cities to the fourth-tier counties.

In 1992, A Bo once worked as a part-time delivery man in Suzhou, and later returned to Luoyang County, Henan Province to be the stationmaster of the US group delivery station for two years. Because I heard that there are many orders in first-tier cities, the unit price is high, and the monthly income can exceed 10,000 yuan, I came to Beijing this fall to become a hungry hummingbird takeaway crowdsourcing.

A Bo explained that both the US delegation and the hungry have special delivery and crowdsourcing teams. The riders who just entered the business generally choose to do "special delivery", which can guarantee the basic income in the team, but the experienced riders choose to do "crowdsourcing". It takes a little longer to take orders freely, and the price of the list that runs far away is higher.

In Abo’s view, Meituan has a very high penetration rate in third-and fourth-tier cities and sinking markets. In 2016, Meituan has opened up county markets such as Luoning, and it was not until 2018 that it was hungry to accelerate its entry into these areas.

In Beijing, the two platforms give crowdsourcing riders "almost the same amount of tickets". If you are hungry, 9 yuan crowdsourcing each ticket, praised 1 yuan, and Meituan crowdsourcing each ticket, praised 1.5 yuan. Coupled with weather subsidies, praise, attendance and other rewards, there is no difference in the overall income of riders.

There is only one difference. When the US group crowdsources meals and delivery is delayed, the rider’s deduction needs to be exempted through online appeal; When you are hungry, hummingbird crowdsourcing directly cancels the time limit for picking up meals from merchants, reducing the deduction fee for overtime delivery.

Such a difference in process is important for ABO. A Bo has always been careful. He said, "You have to run at least 7,000 yuan a month to take care of your family." He and three riders huddled in a 20-square-meter bungalow, and went out at 7: 00 a.m. until the early morning to make money and save money. He said that when his parents are old, he also wants to "marry a daughter-in-law to repair the house", and his two roommates have to support their wives and children in their hometown.

Even if he delivers hungry takeout food, A Bo is proud to have been the "Minions" of the US group. Every time in the dead of night, A Bo always misses the days when he delivered takeout in his hometown, boasting and betting. At that time, he was the most famous takeaway brother of the US group. Until now, he has been wearing the work clothes of the US group when shooting videos.

At that time, whenever the take-away rush hour passed, A Bo would watch Aauto Quicker eat and shoot a video. The boss curiously bet with him that if his fans exceeded 10,000, he would give 500 yuan a reward. Unexpectedly, Abo shot more than 250 videos in one year and gained nearly 40,000 fans, which also brought him confidence and anticipation.

He said that he often feels inferior because of unclear speech. However, in Aauto Quicker, many users in the same city will follow him to order "the same paragraph" for take-out, and a little girl from school specially came to ask for his signature.

What makes A Bo most proud is a good thing he did when he was a rider of the US Mission. At that time, there were many "Bao Ma non-profit organizations" on hand. When they found him in the live broadcast room and asked Abo to help send the donated materials to the local poor households, he did not hesitate. He rode an electric car for more than ten kilometers in one breath and sent the materials and his own money to the poor families.

There are not a few take-away riders like Abo all over the country, and they grow up with the distribution system that pursues efficiency and speed. But from a personal point of view, they even hope that the competition of take-away platforms will last longer and they can get more subsidies themselves.

From sight to poetry and distance.

From the factory to the takeaway platform, from the third and fourth lines to the first and second lines, it is one of the manifestations of the continuous extension and scale of the industrial chain in the competition process of the takeaway platform. As ordinary people in the internet tide, Xiao Xiao and A Bo revealed their helplessness to the pressure of life and their longing for the future. Most riders are busy with "struggling in front of them", but some people dream of "poetry and distance".

When I met Zhou Lei, he was recording the annual finals of CCTV variety show "Avenue of Stars". His other two identity tags were "Little Takeaway Brother God" who had more than 300,000 fans in his hands and the first takeaway rider who won the monthly championship of "Avenue of Stars".

Zhou Lei, 31, has lived in the rural area of Qinhuangdao since childhood. She never thought that she would embark on the road of performing arts. Singing is just a way to entertain herself and relieve pressure.

Before joining the US Mission, Zhou Lei was unemployed at home and didn’t want to go out. He said that there were not many job opportunities in the county. He worked as an ore truck driver and sold potted plants on the roadside. In order to let his children enjoy a better education, he borrowed money to buy a house and moved to the city.

Last October, Zhou Lei took a video of singing in a fast hand wearing the take-away work clothes of Meituan. Unexpectedly, it suddenly became popular and attracted more and more fans’ attention. He said that every day, someone waited for him to sing and order songs in the live broadcast room. After two months, the income of fans’ rewards was actually 40,000 yuan, which suddenly eased the family’s economic pressure.

The real turning point comes from the attention of the "talent scout" on the fast hand. In November last year, Aauto Quicker, a private letter from Zhou Lei, received an invitation claiming to be "the crew of Jilin TV variety show Family Fun Show", and left the county life circle for the first time to start recording programs in big cities. Since then, it has moved to bigger stages such as "100 seconds of gold" and "Avenue of Stars".

Zhou Lei felt the power of the Internet. He said that TV editors and directors will not charge a penny for discovering "material" on a short video platform like Aauto Quicker. Moreover, there are many professional musicians in Kuaishou’s hands. They often interact and learn skills and give him professional guidance, which is a valuable resource for Zhou Lei who has never received professional music training.

Even when delivering takeout food, Zhou Lei obviously felt the love and respect of users. A customer named Zhou Lei to take delivery and asked him to sing a few songs on the spot. A local fast food restaurant also invited him to sing. Later, because of the popularity of Zhou Lei, it became the most famous "online celebrity Restaurant" in the county.

On Aauto Quicker, Zhou Lei was often teased by netizens as "a singer who was delayed by the take-away platform". However, he believes that it is the identity of the US group rider that makes him get more attention than others. Even on the performance stage of "Avenue of Stars", the yellow take-away uniform of the US Mission is his iconic image.

Zhou Lei, who became a monk halfway, hitchhiked on the Internet, and he became "the hope of the whole village" in the eyes of the villagers. More riders need to do their best to maintain the living needs of a wanderer and support their elderly parents and school children. More importantly, they all have light in their hearts, and they all have their own "poetry and distance", just like a small goal-to save money by their own efforts, to go back to their hometown to shoot a video of the mountain village one day, and to bring the villagers together to make a fortune.

"Meituan is a mysterious organization"

In fact, in the huge life industry chain composed of more than 500,000 riders, 4.4 million merchants and 380 million users, the rider profession is getting more and more recognition and respect. In the huge social and industrial transformation, riders are burdened with the confusion of life and the burden of family, and they are also looking forward to social recognition.

In the stories of several interviewees, take-away riders are a particularly mobile industry. Sometimes, a site with about 20 people changes more than a dozen people a month. Some people envy how much money they earn by sending takeout food. There are many experienced riders who have worked for several years. Some people leave because they can’t eat hard after working for a few days, and some people leave because of bad reviews from users and family reasons, just like a song sings, "When you say goodbye, you will leave."

For many riders, Aauto Quicker is a very special circle of friends. Usually, the original intention of sending videos is to cheer themselves up and tell strangers about their troubles that they can’t tell their family and friends, but they soon find out that they have found fellow villagers and peers here and found more understanding and recognition.

According to incomplete statistics, at present, there are more than 40,000 on-the-job riders in Aauto Quicker who use short videos to communicate, and there are not a few riders with tens of thousands and hundreds of thousands of fans. The "Little Fatty" with the most fans has attracted more than 950,000 people’s attention.

Xiao Pang said that in Aauto Quicker’s short videos, he could feel people’s goodwill and respect for the riders of the US Mission, and he also agreed that many videos reflected the hardships of riders’ lives.

For example, when a rider delivers food upstairs, the meal left downstairs is stolen, so he can only order another one at his own expense; When a rider comes across a slip with a wrong address or a hidden address, he can only call the customer again and again to explain it; Some riders have to pay for their own meals returned by customers because of overtime or spilled soup, so they have to take them home to eat; Some riders are sad in the center of the heavy rain, and they will stand on the road and cry while walking.

These common experiences give riders a natural sense of closeness. They cheer each other and share joys and sorrows. Xiao Pang said that he met many riders in Aauto Quicker, commented or interacted with each other live, and sometimes met and chatted in each other’s cities, just like they had known each other for many years. Now, Xiao Pang intends to transform into an e-commerce, and also find people to do business with through Aauto Quicker, and introduce and inspect the source of goods through the riders’ friends in Yiwu.

According to incomplete statistics, at present, there are more than 100,000 user-related and theme videos of Meituan riders published on Aauto Quicker platform, and many real stories of riders have been adapted into short video works. In these videos, riders use their own frustrations to dissuade boys who want to jump into the river and commit suicide. When they see kidnapped girls, they cleverly track and save people, take off their raincoats to take their babies out of the rain in the wind and rain, and try their best to rescue gas poisoning when taking meals in restaurants. They are "new urban youths" with ideals, skills and responsibilities, supporting the Internet life industry chain and conveying positive social energy, which has infected the fierce take-away business war with warmth.

In the eyes of more people in Aauto Quicker, "Meituan is a mysterious organization", because the rider brother in the video can do almost anything: they can catch thieves, help comatose old people, perform singing, play drums and even make a disc DJ in the street, draw a beautiful "Piggy Peggy" according to the requirements of the customer’s order, and even go to the kitchen to cook when the restaurant bursts …

According to the introduction of the official website of COMAC CHINA, "C919" is the abbreviation of the code name of "COMAC919", and "COMAC" is the abbreviation of the English name of China Commercial Aircraft Co., Ltd. The "C" in the abbreviation is not only the first letter of COMAC, but also the first letter of the English name of China in China, which reflects that the large passenger plane is the will of the country and the expectation of the people.

C919 large passenger plane is a short-range commercial trunk aircraft with independent intellectual property rights in China. The standard range design range of C919 aircraft is 4075km, and the extended range design range is 5555km, which can meet the operating requirements of airlines for different routes. The maximum take-off weight of the standard voyage aircraft is 72,500 kg, and the maximum designed economic life is 90,000 flight hours/60,000 flight cycles /30 calendar years. The basic full economy class layout is 168 seats, and the mixed class layout is 158 seats.

C919 passenger plane in the final assembly process

A large number of advanced technologies are adopted in the design of C919, including: advanced aerodynamic layout and new generation supercritical airfoil and other advanced aerodynamic design technologies; Advanced engine to reduce fuel consumption, noise and emissions; Advanced structural design technology and a large proportion of advanced metal materials and composite materials; Advanced fly-by-wire control and active control technology; Adopt advanced integrated avionics technology; Advanced cabin comprehensive design technology to improve cabin comfort; Advanced maintenance theory, technology and methods to reduce maintenance costs.

C919 will use a large number of advanced composite materials and advanced Al-Li alloys, among which the amount of composite materials will reach 20%, and then the weight of the aircraft will be reduced through the detailed design of the internal structure of the aircraft. In addition, C919 will use domestic aluminum alloys, titanium alloys and steel, which account for 20-30% of the structural weight of the whole aircraft. C919 adopts four-sided windshield. This technology is an advanced technology in the world. At present, only the latest Boeing 787 is used in trunk passenger aircraft. Its windshield has a large area and a wide field of vision. Because of relatively few openings, it simplifies the fuselage processing industry and reduces the aerodynamic resistance of the aircraft head.

The C919 uses the LEAP-1C turbofan engine developed by CFM International, a joint venture between American General Electric and French SNECMA (Safran Group). The core engine of this engine is a 10-stage high-pressure compressor driven by a two-stage high-pressure turbine, and its total pressure ratio is as high as 50, far exceeding the current CFM-56 level of about 25. The blade profile in the high-pressure turbine adopts the third generation three-dimensional aerodynamic design, which has advanced aerodynamic characteristics and adopts high-performance materials and advanced cooling technology. According to relevant data, LEAP-1 can reduce fuel consumption by 16%, carbon dioxide emission by 16%, nitrogen oxide emission by less than 60% and be quieter than the existing CFM-56.

C919 passenger plane in the final assembly process

It is estimated that the localization rate of C919 is about 50% at the first flight, and it will exceed 90% after 2025. A great deal of equipment on this aircraft is made by China itself: the nose radar is made by AVIC Tianjin. The nose is made by AVIC Chengdu. The tail and vertical tail are made by AVIC Harbin. The center wing box, outer wing box, wing section and aileron are manufactured by AVIC Xi ‘an. The front fuselage, middle fuselage section and rear fuselage equivalent section are manufactured by AVIC Hongdu. The leading edge flap and trailing edge flap are manufactured by AVIC Changhe. AVIC Shanghai is the first production line and assembly plant, and AVIC Hongdu is the proposed second production line and assembly plant. In order to support the production and final assembly of C919, Nanchang Aviation Industry City (the new site of AVIC Hongdu) started construction in 2009, and it is planned to start producing the main components of C919 in the fourth quarter of 2012.
