In the first three quarters, the agricultural and rural economy maintained a trend of continuous improvement, stability and progress. The agricultural production situation is good, the grain harvest is a foregone conclusion, and the output is expected to reach the best level in history; The income situation of farmers has improved quarter by quarter, the employment channels of farmers have been continuously broadened, and rural industries have increased their income. The role of ballast stones in agriculture, rural areas and farmers is more prominent, which provides strong support for stabilizing the overall situation of economic and social development.

Recently, the Ministry of Agriculture and Rural Affairs held a press conference on the operation of agricultural and rural economy in the first three quarters of this year. At present, the grain harvest is a foregone conclusion, and the output is expected to reach the best level in history; The added value of the primary industry was 4,812.3 billion yuan, a year-on-year increase of 2.3%; Farmers’ income was 12,297 yuan, up 1.6% year-on-year.

"In the first three quarters, the agricultural and rural economy maintained a trend of continuous improvement, stability and progress, and the role of’ three rural’ ballast stones became more prominent, providing strong support for stabilizing the overall economic and social development." Wei Baigang, chief economist of the Ministry of Agriculture and Rural Affairs and director of the Development Planning Department, said.

The agricultural production situation is good, and the annual grain harvest is a foregone conclusion.

In autumn and October, rice is fragrant, and this year’s agricultural harvest is hard to come by. The agricultural production situation is good, which has become a prominent highlight of the national economy.

There was another bumper harvest in the whole year, and the variety structure was further optimized. Wei Baigang introduced that summer grain and early rice have been harvested this year, with an increase of 2.42 billion Jin and 2.06 billion Jin respectively over the previous year. In particular, the area of early rice has reversed the downward trend for seven consecutive years. The harvest of autumn grain is close to 80%, and the harvest is a foregone conclusion. It is estimated that the annual grain output will hit a record high, and will remain above 1.3 trillion Jin for six consecutive years. The planting structure has been continuously optimized, with the proportion of high-quality special wheat reaching 35.8%, the area of high-quality rice further expanded, and the area of soybean is expected to increase for five consecutive years.

The green development of agriculture has been solidly promoted. The utilization rate of livestock manure resources reached 75%, achieving the set goal one year ahead of schedule; The protective farming area of black land in Northeast China reached 46 million mu, exceeding the annual target of 6 million mu; The quality and safety level of agricultural products has been steadily improved, and the supply of green and high-quality agricultural products has increased significantly. The pass rate of sampling inspection in the first three quarters has remained above 97%, which is stable at a high level.

The Yangtze River’s ban on catching and retreating has achieved phased results. A total of 84,000 fishing boats have been disposed of and 179,700 fishermen have withdrawn from the key waters of the Yangtze River Basin, basically completing the task of withdrawing fishing; 168,700 fishermen who have retired have implemented social security, accounting for 93.32% of the approved tasks; There were 118,400 people who changed jobs, accounting for 93.57% of the people who needed to change jobs; Clean up and ban 24,500 ships involved in fishing and 175,100 illegal nets, laying a solid foundation for the 10-year fishing ban in key waters of the Yangtze River basin from January 1 next year.

While doing a good job in autumn harvest, autumn and winter planting has been fully launched. The latest agricultural situation scheduling shows that the national winter wheat planting progress has reached nearly 60%, 3 percentage points faster than the same period of last year, and the winter rape planting has exceeded 40%. "Most of the areas planted in autumn this year are suitable for moisture, which is more conducive to the smooth development of autumn and winter planting." Liu Lihua, deputy director of the Planting Management Department of the Ministry of Agriculture and Rural Affairs, said.

The income situation of farmers has improved quarter by quarter, and the actual growth rate has turned from negative to positive.

At the beginning of this year, the epidemic in COVID-19 had a great impact on farmers’ income. What is the current income situation? "In general, with the effective expansion of farmers’ employment channels, high agricultural yield and income increase, the income situation of farmers has improved quarter by quarter." Wei Baigang said. In the first three quarters, the growth rate of farmers’ income turned from negative to positive, reaching 12,297 yuan, with a real increase of 1.6%, which was 0.9 percentage points higher than that of GDP and 1.9 percentage points higher than that of urban residents.

On the one hand, broaden farmers’ employment channels.

-For migrant workers who go out for employment, timely release employment information, carry out special recruitment, and organize "point-to-point" and "one-stop" direct delivery services to ensure safe and orderly return to work. At the end of the third quarter, the number of rural laborers who went out to work reached 179 million, an increase of 2 million over the second quarter; The average monthly income was 4,035 yuan, a year-on-year increase of 2.1%.

-For migrant workers who have returned from their hometowns, we will increase support for employment and entrepreneurship, implement a one-off entrepreneurship policy, carry out employment and entrepreneurship training, expand the scale of work-based relief, and create public welfare posts. At present, migrant workers who have returned to their hometowns have basically achieved stable employment or flexible employment nearby.

On the other hand, efforts should be made to increase the income of rural industries.

-improving the efficiency of agricultural production. Guide to expand the production of high-quality special wheat and rice, and promote order production; Vigorously develop production custody services such as substituting seeds for ploughing and unified prevention and control, and the agricultural socialization service area exceeds 1.5 billion mu; Establish a docking platform for production and marketing, and strive to achieve high quality and good price of agricultural products.

-Accelerate the recovery of rural industries. At present, the agricultural product processing industry has recovered to the same level as last year. It is estimated that the operating income of the agricultural product processing industry above designated size will exceed 10 trillion yuan in the first three quarters. Leisure agriculture and rural tourism projects, such as farmhouses, restaurants and homestays, are fully open, and 1,000 rural leisure tourism routes jointly recommended by the Ministry of Agriculture and Rural Affairs and the Ministry of Culture and Tourism have become punching places for urban and rural residents to enjoy autumn travel during the "Eleventh Five-Year Plan" period. Online sales of agricultural products have maintained double-digit growth, and it is estimated that the online retail sales in the first three quarters will exceed 300 billion yuan.

In the first three quarters, the growth rate of farmers’ income in poverty-stricken areas continued to be higher than the national average of rural residents. Wei Baigang introduced that at present, 832 poverty-stricken counties have implemented more than 1 million industrial poverty alleviation projects and built more than 300,000 industrial poverty alleviation bases. Each poverty-stricken county has formed 2-3 leading poverty alleviation industries with distinctive characteristics, and 72% of poor households have established interest links with new business entities. Industrial poverty alleviation has become a poverty alleviation measure with the widest coverage, the largest number of poor people and the greatest achievements.

"Last year, farmers’ income exceeded 16,000 yuan, doubling the target of 2010 one year ahead of schedule. As long as farmers’ income maintains positive growth this year, this goal can be consolidated. " Wei Baigang said that there are still nearly three months before the end of the year. In order to further consolidate the good momentum of increasing farmers’ income, the next step will be to implement the mid-late rice purchase policy, strengthen the connection between production and marketing, seize the window period to increase the income of migrant workers, and cooperate with the human and social departments to do a good job in supervising the unpaid wages of migrant workers at the end of the year, so that migrant workers who have worked hard for a year can get their income in full and on time and go home happily for the New Year.

Investment in agriculture and rural areas has rebounded rapidly, and infrastructure has been accelerated.

The decisive battle to get rid of poverty and build a well-off society in an all-round way has a heavy task in the field of agriculture, rural areas and farmers. This year, the No.1 Document of the Central Committee and the Government Work Report have made comprehensive arrangements for the work concerning agriculture, rural areas and farmers. Wei Baigang introduced that at the beginning of this year, the Ministry of Agriculture and Rural Affairs specially studied, formulated and issued the implementation opinions on the deployment of key tasks throughout the year, and identified 37 key tasks, which are progressing smoothly and many of them have been basically completed.

In July this year, seven ministries and commissions, including the Ministry of Agriculture and Rural Affairs, issued policy documents to expand effective investment in agriculture and rural areas, and identified 11 key areas to make up for shortcomings. Recently, the General Offices of the General Office of the Central Committee of the CPC and the State Council issued the Opinions on Adjusting and Perfecting the Use Scope of Land Transfer Income to Give Priority to Rural Revitalization, requiring that the proportion of local land transfer income used for agriculture and rural areas should reach more than 50% by the end of the 14th Five-Year Plan period.

Driven by a series of policies with high gold content, investment in agriculture and rural areas has rebounded rapidly, and the shortcomings of infrastructure have been accelerated. All localities have increased the support of local government bonds in the fields of agriculture, rural areas and farmers, focusing on supporting high-standard farmland, rural human settlements improvement, modern agricultural industrial parks, and cold chain logistics facilities for agricultural products storage and preservation. From January to August, it supported the issuance of bonds totaling 108.4 billion yuan. Driven by various policies and major projects, the investment in fixed assets in the primary industry reached 1,165.3 billion yuan in the first three quarters, up 14.5% year-on-year, achieving positive growth for four consecutive months, with the growth rate increasing by 16.7 percentage points over the same period of last year.

"Next, we must continue to strengthen the construction of agricultural and rural infrastructure." Wei Baigang introduced that the construction of high-standard farmland should ensure the completion of 80 million mu for the hard task of benchmarking this year; Complete the three-year action objectives and tasks of rural human settlements improvement in an all-round way, promote rural toilet improvement in an orderly manner, and promote rural domestic garbage sewage treatment as a whole; Improve the level of resource utilization of livestock manure, and ensure that the supporting facilities for manure treatment in large-scale farms reach 95% and that in large-scale farms reach 100%. At the same time, it is also necessary to support farmers’ cooperatives and family farms to build cold chain logistics facilities for agricultural products storage and preservation, and improve the level of commercialization of agricultural products.

Original title: Fantastic Animals 3: The Mystery of Dumbledore: Has the magical world lost its charm?

With the aura of "Harry Potter", Fantastic Animals 3: The Mystery of Dumbledore came at last under the impact of the COVID-19 epidemic, which can be described as full of ambition. However, the reality is not satisfactory. Whether it’s a die-hard Harry Potter fan, a new "magic animal" fan, or a passerby audience, it seems that they are not satisfied with this new film. Douban score has been falling all the way, from 7.7 in the first part to 7.0 in the second part, and now to 6.1 in the third part. Also directed by David Yates and written by J.K. Rowling, why did the quality of Fantastic Animals 3 drop so badly? To answer this question, we need to go back to the beginning of the whole "Harry Potter movie universe".

In 1997, Joanne Catherine Rowling, a 32-year-old English teacher living in Britain, applied for a grant of 13,000 pounds from the Scottish Art Association, and finally she was able to crystallize her years of hard work — — The novel Harry Potter and the Sorcerer’s Stone was delivered for publication. At that time, Joanne probably didn’t realize that the story of this little wizard, which she conceived on a train trip many years ago, will be translated into 73 languages in the next 20 years, with global sales exceeding 500 million copies and making her one of the richest women in the world.

"Harry Potter" can become the largest IP with the most global influence in the early 21st century, and Warner Pictures has contributed a lot. From the first film "Harry Potter and the Sorcerer’s Stone" in 2001 to the final chapter of the series in 2011, eight films were made in ten years, with a global box office of over 7.7 billion dollars. Because movies have stronger penetration ability than novels, although the content of novels inevitably gains and losses in the process of film adaptation, more audiences are familiar with Harry Potter’s story series through movies. Especially since the fifth part, novels and movies have started a mutual promotion development model, and through the iterative development of the global network new media community, the attention of the global audience has been continuously enhanced. Unfortunately, due to various restrictions, Harry Potter’s novels finally ended in the seventh Harry Potter and the Deathly Hallows. From the perspective of literary creation, the end of the seven-part series is not perfect, but it is quite wonderful enough to make J.K. Rowling a legendary writer in the history of children’s literature in the world. However, for Warner Pictures, the film producer, this is far from enough. Anyone who knows a little about the operation mode of modern commercial films will know that the biggest risk of the film industry comes from the uncertainty of the box office. And a film series can create a stable box office of about 960 million dollars per film in ten years. For film companies,Undoubtedly, it is an indispensable "cash cow" and an excellent material for the company’s management to "tell stories" about the capital market. Therefore, for film companies, the popularity of the Harry Potter series must continue in some form. This is what we know today as the "Fantastic Animals" series.

In the wizarding world of Harry Potter, Fantastic Beasts and Where to Find Them is a very important book, which describes all kinds of magical creatures in the wizarding world. This book was written by J.K. Rowling under the guise of "Newt Scarmand", which can be regarded as the author’s attempt to further present the "magical world" in his mind, and also laid the groundwork for the subsequent brand-new creative plan.

At the end of 2016, "Fantastic Beasts and Where to Find Them" was released as the first film in the Fantastic Animals series. This is the first original film based on "The Wizarding World of Harry Potter", and it is also the beginning of the prequel five-part series of Harry Potter. It is worth noting that in July of the same year, the stage play Harry Potter and the Cursed Child, as an orthodox sequel to the Harry Potter series, was released in Britain, which was also an original work without novel support. Connecting the two, it is not difficult to see that the consensus of all parties concerned with IP interests at this time is that not only the story system should be added, but also the business model should be subtracted — — It doesn’t matter whether there is an original novel or not. The name "Harry Potter" alone can pry open the public’s wallet.

But from the actual effect, it is not satisfactory. On closer inspection, the main stage of both novels and movies is at Hogwarts School of Witchcraft and Wizardry, which can be described as "small scenes and big scenes", and the creators can be as elaborate as ivory carvings. From novels to movies, professional film production teams can simplify the original works and highlight the backbone, so that the original party and passers-by audience can be satisfied separately.

However, in the series of Fantastic Animals, the film creation is gradually developing in the direction of collapse, and the key point is that all stakeholders in IP want too much — — It is necessary to position itself as a prequel to Harry Potter and show the long-cherished wish of Dumbledore and the first generation of "the Great Devil" Grindelwald; It is also necessary to show magical creatures and expand the scope of "the magical world of Harry Potter"; It is also necessary to get rid of the positioning of "youth movies" and March towards all ages, and even evolve into a "movie universe" … … Objectively speaking, Fantastic Beasts and Where to Find Them, the first film in the series, still maintains the consistent tonality of the Harry Potter series, J.K. Rowling’s iconic "suspense-reversal" narrative mode continues, and the display of magical animals is basically the driving factor of the main plot. However, in Fantastic Animals 2: The Crime of Grindelwald, because of too much consideration, a large number of plot designs went into a dead end, which destroyed the integrity of the narrative logic of the film. Because too many new characters are added, and there is not enough time to lay out the growth curve of the characters, both new and old characters tend to be instrumental. But finally left a fairly satisfactory plot hook at the end of the story.It left the audience with the expectation that the villain camp was about to make a big event.

Disappointingly, whether as a single film work or as a connecting link in the series, Fantastic Animals 3: The Mystery of Dumbledore is hardly qualified. First of all, as the focus of the last film, the villain Grindelwald’s "plan to seize power" and the fateful battle between Dumbledore and Grindelwald were all handled very hastily, giving people a feeling of "getting things done as soon as possible". Secondly, the behavioral motives of the characters are unclear, and the roles are collectively degraded. As the most important "magical animal" in the film, although it can be seen that the director tries to let them play the role of promoting the main plot, it actually makes the magical animal role more instrumental and even makes it a dispensable existence.

Although we don’t know the whole picture of the creative process of Fantastic Animals 3, judging from the state presented by the film, all stakeholders are not in a state of joint efforts, but in a state of mutual game. Fantastic Animals 3 is the greatest common denominator after this game, taking care of all aspects, but in the end no one is satisfied.

Before and after the release of Fantastic Animals 3, there were rumors that Warner Pictures intentionally suspended the production of this series after the management adjustment. In fact, whether it’s to finish this series, or to start a new business, as long as there are enough loyal fans in the Wizarding World of Harry Potter, the legend of the Wizarding World will continue. In short, as long as the capital never sleeps, the "story" can always go on.

The weather is getting hotter and hotter, and there are more and more annoying mosquitoes. Many friends who keep cats and dogs have the same confusion and trouble: will mosquito repellent products drive away their cats and dogs? What mosquito repellent products are safest for them?

Mosquito-repellent incense and electric mosquito-repellent incense: dogs can’t be cats.

Mosquito-repellent incense and electric mosquito-repellent incense are most commonly used at home, and the active ingredients of both are pyrethroids, such as permethrin, cypermethrin and deltamethrin. Its principle of killing mosquitoes is to affect the nervous system of mosquitoes. First, it induces mosquitoes to be excited, and then its nerve conduction is blocked, leading to paralysis and death.

Pyrethroids have low toxicity to humans, are difficult to be absorbed by human skin, are easily metabolized by the liver, and have low toxicity to dogs.

However, this component is highly toxic to fish, amphibians and reptiles, and it is also very toxic to cats. Cat’s liver can’t metabolize pyrethroids. If mosquito-repellent incense is lit and cats are kept in a closed environment at the same time, it may lead to cat poisoning, fever, epilepsy, ataxia and other symptoms, and may even cause cat death.

Does it mean that a cat can’t light mosquito-repellent incense? In fact, it is still possible to use the right method. You can close the doors and windows of the room first, then use mosquito-repellent incense or electric mosquito-repellent incense to repel mosquitoes, then open the doors and screens for ventilation, and let the cat in after the smell is completely dispersed, which is relatively safe.

In addition, mosquito-repellent incense has the risk of burns to cats and dogs. Bottom map: pixabay

Mosquito repellent: discuss separately

There are many kinds of mosquito repellent products on the market, and the effective components with mosquito repellent effect approved by the World Health Organization, the US Centers for Disease Control and Prevention and the US Environmental Protection Agency are as follows:

DEET (/diethyltoluamide, abbreviated as Deet)

Picaridin/Icaridin

Mosquito repellent ester (IR3535)

Lemon eucalyptus oil (OLE)

P-menthane diol (PMD)

2- undecanone

These six ingredients are different in nature and characteristics, so let’s talk about them one by one.

DEET: It should be all right.

DEET, also known as DEET, DEET and DEET, is the most widely used component of mosquito repellent liquid and the most recommended component of mosquito repellent liquid for children by American Academy of Pediatrics. So I have to say more about it.

DEET does not poison mosquitoes, but works by blocking the function of odor receptor of olfactory protein of mosquitoes. Simply put, it is to make mosquitoes unable to smell people and find people.

The mosquito repellent liquid containing DEET in the supermarket usually contains about 7% to 10% DEET. The concentration mainly affects the action time. The concentration of 7% can last for about 2 hours, and the concentration of 30% can last for 6 hours. But the higher the concentration, the better.

DEET is corrosive: high concentration of DEET can dissolve plastic, nylon, chemical fiber, leather and nail polish, etc., and the smell is not very good, and it is sticky. Therefore, as long as we spray it once every once in a while, even 7% mosquito repellent can have a good effect.

So how toxic is DEET to cats and dogs? The toxicological report of DEET issued by the United States Environment Agency shows that exposure to 9% DEET spray for cats and dogs will cause symptoms of depression, irritability, excessive salivation, ataxia, seizures and muscle tremor. Among them, dogs have higher tolerance to DEET than cats.

Higher concentrations of DEET mosquito repellent are more likely to cause poisoning in cats and dogs, mainly because they like to lick and bite, which is easy to be taken by mistake. However, in the guidance issued by the US Centers for Disease Control and Prevention and the US Environment Agency, it is also mentioned that DEET can be used to repel mosquitoes for good friends of humans such as cats, dogs and horses. A small amount of exposure to low concentrations of DEET may not be a big problem.

Patrick Redding: I don’t know.

Picaridin is currently considered as the most effective mosquito repellent besides DEET. When it was first declared, its name was Picaridin, and it became Icaridin after it was approved. So, whether it’s Patrick Redding or Ekredding, it’s one thing.

Pekaridin’s mosquito repellent principle is to interfere with mosquitoes’ receptors, so that they can’t judge the position of people. Compared with DEET, Pekaridin has more advantages: no odor, no irritation, no stickiness, no corrosion to plastic nylon, and less irritation to eyes and mouth; Disadvantages are that it is more expensive and not as easy to buy as DEET.

It may also have something to do with the difficulty in getting it. Peccaridine has little toxicological research on cats and dogs, and no cases of cat and dog poisoning have been found so far.

Figure pixabay

Most of the mosquito repellent solutions we can buy contain deet and pekaretin. Products containing the remaining mosquito repellent ingredients are more difficult to buy, and there is not much discussion value.

Unreliable mosquito repellent products: forget it

"Pure Plant" Products: Different opinions.

The above-mentioned DEET mosquito repellent liquid is a very safe and effective product. Ironically, many merchants specially marked it when launching mosquito repellent products: it does not contain DEET. The products launched by these merchants often claim to be natural insect repellent ingredients, such as citronella, geranium, clove, mint, eucalyptus essential oil and so on.

In fact, there is no conclusive evidence whether these ingredients can repel mosquitoes or even harm cats and dogs. If you think "no evidence" means safety, use it; Think that "no evidence" means unsafe, then choose other mosquito repellent products.

Mosquito killer: It’s useless.

Mosquito killer claims to use phototaxis to kill mosquitoes, but many mosquitoes don’t like light at all, and the effect is very limited. In addition, if you look directly at ultraviolet light for a long time, it will do harm to people’s eyesight.

At present, some mosquito killer are said to produce carbon dioxide and smell similar to that of human body to attract mosquitoes, but it is hard to say whether this lamp can attract mosquitoes when there are living people.

In a word, although these things are harmless to cats and dogs, it is not recommended that you buy such products, which really have no mosquito repellent effect.

Mosquito repellent stickers and mosquito repellent bracelets: useless.

Mosquito repellent stickers, mosquito repellent bracelets and hand straps are also not good mosquito repellent products.

In August 2018, the staff of Beijing Consumers Association randomly purchased 50 nominally pure plant mosquito repellent products from mother-baby stores, pharmacies, outdoor stores and online channels, involving domestic and some imported mosquito repellent stickers, mosquito repellent bracelets, mosquito repellent buckles, etc.; Beijing No.1 Station for Quality Supervision and Inspection of Light Industrial Products was entrusted to test the contents of effective components in the samples. The results show that all the samples have poor mosquito repellent effect, and the actual use effect is seriously inconsistent with its product promotion. Therefore, mosquito repellent stickers and mosquito repellent bracelets are ok for cats and dogs, but not for you.

In a word, physical mosquito prevention: the most traditional mosquito nets and the electric mosquito swatter are safe and reliable for you and cats and dogs.

Finally, I would like to remind you that mosquitoes at home are mainly related to stagnant water. Check regularly whether there is stagnant water under the refrigerator, flower pots and windowsills at home. Mosquitoes can’t live without water in their infancy. Clearing the stagnant water will also clear the growing environment of mosquitoes, which can reduce the chances of mosquitoes breeding at home from the source.

With the promotion of vaccination in COVID-19, many people have received vaccination notices one after another and made an appointment to vaccinate COVID-19 vaccine. But at the same time of vaccination, many people also questioned: what is the vaccine we are playing? Does it really work?In fact, there are many kinds of vaccines in Covid-19, including inactivated vaccine, adenovirus vector vaccine and mRNA vaccine, as well as COVID-19 vaccines such as recombinant subunit, synthetic peptides and DNA. Each vaccine has different ways and advantages.

Inactivated vaccine is the "base"

Inactivated vaccine is the most traditional vaccine preparation method. Inactivated vaccine can be simply understood as that by injecting artificially inactivated pathogenic microorganisms or their metabolites (antigens) into the body, the human body can recognize the antigens to produce specific antibodies. Once invaded by external specific viruses, these specific antibodies will mediate the body’s defense function and thus resist the invasion of viruses.

Inactivated vaccine is a mature technology, and its safety is good, but the production cycle is long (more than 60 days), and its immunogenicity becomes weak, so it needs multiple immunizations to strengthen the curative effect. Inactivated vaccines on the market include: Japanese encephalitis inactivated vaccine, hepatitis A inactivated vaccine, rabies vaccine, cholera vaccine, etc., which can be said to be widely used.

Figure 1: Inactivated vaccine (from IMMUNOLOGY.org)

COVID-19 inactivated vaccine, which contains inactivated virus SARS-CoV-2, still retains some antigenicity, but it will not cause the vaccinator to be infected with COVID-19; It can be recognized by the immune system and activate the immune response.After the successful establishment of immune memory, the immune system of the vaccinated person will have immune resistance to Covid-19 in the future. At present, Sinovac Kexing Bio, Sinopharm Chinese Medicine and COVID-19 Vaccine from Bharat Biotechnology are all inactivated vaccines.

However, due to the lack of activity, long production cycle and low vector conversion rate of inactivated vaccine, many countries have begun to develop the latest vaccine types …

Table 1: Some clinical trials of COVID-19 vaccine under study [1]

The development of nucleic acid vaccine is "the general trend"

As a newly emerging biological product at the gene level, nucleic acid vaccine plays a vital role in the prevention and control of many diseases such as bacteria, viruses, parasites and tumors.In recent years, with the emergence of various new diseases, the disadvantages of traditional vaccines are gradually exposed, which can no longer meet people’s needs. Traditional vaccines, such as attenuated vaccines and inactivated vaccines, are generally transformed by vectors, and their immune efficiency is low. Studies have found that attenuated vaccines may also have toxic residues, which may lead to the risk of secondary infection. As a new vaccine, nucleic acid vaccine can activate the immune mechanism of the body through specific channels, thus achieving the effect of rapid immunization, which is safer and more efficient than traditional vaccines [2].

Nucleic acid vaccines are mainly divided into DNA vaccines and RNA vaccines. DNA-based vaccines are mostly used in tumors, while the new COVID-19 vaccines currently under development are mostly mRNA-based vaccines. The inoculation method of nucleic acid vaccine and the regulation of influencing factors have great influence on inducing the expression of antigen protein in the body, especially the selection of promoter and vector. In addition, there are various inoculation methods of nucleic acid vaccine, and choosing the appropriate inoculation route of nucleic acid vaccine will help to improve the transformation rate of vaccine. In the future, nucleic acid vaccine will become an indispensable biological product in the fields of human disease prevention and treatment, and has broad application prospects.

MRNA vaccine is expected to become a "hard-core" vaccine against COVID-19 mutation quickly.

Essentially, a nucleic acid vaccine is to inject a plasmid vector with a specific pathogenic microorganism foreign antigen coding gene (mostly DNA) sequence into a specific host cell. Under the control of the vector plasmid, the foreign antigen gene is transcribed into a specific antigenic mRNA (this process usually requires the participation of a strong promoter), and a functional protein is generated through a series of signal transmission to activate the immune response.

At present, many vaccines developed by COVID-19 vaccine research and development companies are mRNA vaccines, and mRNA vaccines have obvious advantages compared with inactivated vaccines..Firstly, because mRNA vaccine does not depend on cell amplification, its detection and quality control are relatively simple. Secondly, the speed of vaccine production is also very important for the current situation because it saves the time of cell culture and expansion and greatly improves the vaccine productivity. At present, as the third generation vaccine technology, mRNA vaccine is a technical route vaccine used by many western developed countries. MRNA vaccine can accurately express antigen and activate the dual immune mechanism of "body fluid +T cells", which has strong immunogenicity and does not need adjuvant.

It is worth noting that on April 6th, 2021, the top medical journal, the New England Journal of Medicine (NEJM), published a communication article from the National Institutes of Health (NIH), reporting the antibody attenuation after 6 months of inoculation with mRNA COVID-19 vaccine (mRNA-1273).

Figure 3: Anti-body persistence through 6 months after the second dose of mRNA-1273 vacuum forcovid-19

In this study, the serum of 33 patients inoculated with two doses of mRNA-1273 was analyzed. Through two neutralization test methods, pseudovirus neutralization test and live virus FRNT test, it was found that the serum neutralization activity of mRNA-1273 vaccinators of all ages continued at ID50100 and above for up to 6 months after vaccination. It can be seen from the curve in the study that the neutralization activity of mRNA-1273 reached the peak 7 days after the second inoculation.

Table 3: Time course of SARS-CoV-2 antibody binding and neutralization reaction after 3：mRNA-1273 vaccination

From the kinetic curve of antibody metabolism provided by this study, it can be seen that the serum neutralizing antibody level is very stable after inoculation with mRNA-1273, and the antibody activity in all age groups remains at a high level on the 209th day of inoculation. Moreover, this result has been verified in three different types of tests. It should be noted that the antibody level does decrease with age.

Write it at the end

Based on the advantages of mRNA vaccine, the World Health Organization (WHO) has approved the urgent use of mRNA vaccine. At present, 68 countries and regions including the United States, Britain, China and Hongkong have introduced mRNA vaccine. But even if the mRNA vaccine is so superior, there are still many disadvantages.

First of all, from the principle of action, when the mRNA vaccine is injected into the host, there is a certain chance that the foreign antigen sequence fragment will be mistakenly integrated into the genome of the organism, causing the disease of the organism [2]. Secondly, from the technical point of view, RNA itself is unstable, and mRNA is likely to be degraded when it enters the body, so it needs to be delivered by additional vectors. In addition, transportation and storage may require very strict and low temperature conditions, which will be a great challenge in research and development.

However, it is undeniable that in the clinical trial reports of various mRNA vaccines, the antibodies produced by them can be maintained in the body for at least 6 months. Some experts believe: "With the research on antibodies and other related factors of immunity after vaccination in COVID-19, it is expected that we will observe that immunity will last for a longer time [4]." It can be predicted that mRNA vaccine represents the world’s leading nucleic acid vaccine route, and together with the traditional technical route vaccine, it will form a joint phalanx of vaccine research and development, which will bring dawn to the decisive victory of global anti-epidemic.

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.

Chronology of C919 Development Events

In January, 2006, China listed the large aircraft project as one of the 16 major projects in the national medium-and long-term science and technology planning.

　　Recently, Taicang, a county-level city under the jurisdiction of Suzhou, issued a "zero cost" entrepreneurship support policy for college students.

　　According to "Several Measures on Supporting Taicang University Science Park to Create the First Choice for College Students’ Innovation and Entrepreneurship in the Yangtze River Delta", the college students’ entrepreneurship project that came to Taitai for the first time directly gave 50,000 yuan of entrepreneurship funding; Those who have settled in the winning projects of the National College Students’ Innovation and Entrepreneurship Competition will be given entrepreneurship funding directly according to the first prize of 500,000 yuan, the second prize of 300,000 yuan and the third prize of 200,000 yuan.

　　In order to reduce the cost of college students’ entrepreneurship, the local government will also give the newly settled college students’ entrepreneurship project in Dakeyuan a three-year rent-free venue; Those who employ college graduates who have been employed for the first time in Taitai will be given a subsidy of 3,000 yuan per person after paying social security for 6 months.

　　On December 16th, the relevant person in charge of Taicang told CBN that they have no restrictions on the content and form of college students’ entrepreneurial projects, and any project can enjoy this policy. "As long as it is registered in Dake Park, this is the first in China". Once the registration is completed, the 50,000-yuan business start-up grant will be paid to the company account at one time.

　　This package of support policies for college students’ entrepreneurship is under the background that the Ministry of Education issued the Notice on Doing a Good Job in the Employment and Entrepreneurship of College Graduates in 2024 (hereinafter referred to as the Notice) on December 1. The "Notice" decided to implement the "Promotion Action for Employment and Entrepreneurship of College Graduates in 2024", continuously improve the employment and entrepreneurship service system for college graduates, and fully promote the high-quality and full employment of college graduates.

　　The above policy of Taicang will be implemented on January 1, 2024, with a trial period of one year, and the Talent Office of the Municipal Party Committee, High-tech Zone and relevant departments will be responsible for the interpretation.

　　Ceng Gang, dean of the Urban Development Research Institute of East China Normal University, told CBN that the latest policy issued by Taicang provides a new case for attracting talents from all over the country in the new era, and is generally implementing concrete actions for the integration and development of scientific and technological innovation and industrial innovation. "Taicang hopes that by holding ‘ Talent ’ This bull’s nose is a wise move to achieve the goal of innovation and high-quality development. From the perspective of specific fields, providing employment subsidies for talents and optimizing the ecological environment for innovation and entrepreneurship are effective and effective. "

　　However, Ceng Gang suggested that optimizing the investment environment and attracting foreign and local investment to promote college students’ employment should be the main and important policy direction. Considering the high risk of entrepreneurship and the lack of business experience of college students, it is debatable to take college students’ entrepreneurship as the first priority of preferential policies.

　　Taicang’s above-mentioned talent policy says it will increase financial support for entrepreneurship. For example, an angel investment fund of 300 million yuan was established, and the highest equity investment of 3 million yuan was given to the entrepreneurial projects of college students. We launched the "Loucheng College Students’ Entrepreneurship Loan", a government-enhanced financial product, to provide risk compensation, with a maximum loan of 1 million yuan for a single project. At the same time, increase subsidies in technology and finance, and grant loans to enterprises such as "Suke Loan" and "Louchengke Creation Loan" at the rate of 5&permil of the actual payment; Give a subsidy of up to 500,000 yuan/year; For enterprise intellectual property pledge financing, the maximum reward is 100,000 yuan according to 1% of the actual financing amount.

　　The goal of Taicang’s new policy is to create the first choice for college students’ innovation and entrepreneurship in the Yangtze River Delta. As the first choice for college students’ innovation and entrepreneurship in China, the war of grabbing people in the Yangtze River Delta region is becoming increasingly fierce.

　　In recent years, Anji County, Huzhou City, Zhejiang Province, which has increased its efforts to develop new economic industries, has also introduced a package of policies with great efforts around the strategic goal of "introducing 100,000 young college students" this year.

　　Among them, in terms of entrepreneurship subsidies, Anji gives college students or college students who come to start a business for the first time within five years after graduation an entrepreneurship subsidy of 2,500 yuan/month, which will be enjoyed from the next month after normal operation, with a subsidy period of one year. For eligible Qingchuang projects that have settled in Qingchuang Space, a startup subsidy of 2,500 yuan/month will be given, with a subsidy period of 1 year; Those selected as Class A, B, and C youth creation projects will be given 220,000 yuan, 90,000 yuan, and 30,000 yuan respectively, which will be allocated by 50% in two phases. Support the third-party operation and management of Qingchuang Space, and give a maximum financial reward of 150,000 yuan.

　　In addition to entrepreneurship subsidies, talents who come to Anji for employment and entrepreneurship can also receive monthly subsidies for settling down and renting houses. Among them, 2000 yuan/month for doctoral students, 1200 yuan/month for master students and "double-first-class" university graduates, 400 yuan/month for other undergraduate graduates and 250 yuan/month for college graduates. As for the rental subsidy, the period of subsidy is 2,200 yuan/month for doctoral students, 1,500 yuan/month for master students and "double-class" university graduates, 800 yuan/month for other undergraduate graduates and 650 yuan/month for junior college graduates.

　　In addition to Jiangsu and Zhejiang, Shanghai and Anhui have also introduced relevant measures for talent employment and entrepreneurship this year. Yao Kai, director of the Global Science and Technology Talents Development Research Center of Fudan University and chief expert of the Shanghai Talent Theory Research Base, said earlier that in the face of the complicated and changeable situation of attracting talents, a single talent development measure has been difficult to meet the needs of long-term sustainable development of talents. In addition to the attractive talent policy, it also needs to be equipped with comprehensive, systematic and operational support measures.

　　While the war of robbing people is escalating, the integration of talents in the Yangtze River Delta is also expected to accelerate. The 5th Yangtze River Delta G60 Science and Technology Corridor Talent Summit, which opened in Huzhou, Zhejiang Province on December 16th, focused on deeper talent integration, released the Implementation Plan of Yangtze River Delta G60 Science and Technology Corridor Talents Leading Innovation Highland Construction (2023-2025), signed a cooperation project on talent integration in nine cities of Yangtze River Delta G60 Science and Technology Corridor, and established a strategic cooperation alliance for the introduction and education of young talents in nine cities.

Recently, Insuramore, a British research institution, announced the top 15 insurance brokerage companies in the world in 2022. The three well-known brokerage companies, Wei Daxin, Aon and Wei Lai Tao Yue, still dominate the list, and other institutions on the list are relatively stable.

According to Insuramore’s data,In 2022, the total brokerage business of all brokerage companies in the world reached $151.393 billion, of which the top 300 brokerage companies accounted for 83.2% of the total brokerage income in the world..

The top 15 insurance brokerage companies in the world collected a total of 71.446 billion US dollars, accounting for 47.2% of the total brokerage business income of all brokerage companies in 2022, nearly half.. The total brokerage income of all other brokerage companies not on the list reached $79.948 billion, accounting for 52.81%.

Judging from the scale of brokerage income,The largest brokerage company in the world is still Wei Daxin, whose brokerage business income in 2022 was $16.338 billion., accounting for 78.9% of the total revenue, and its global market share reached 10.79%.

Aon ranked second with brokerage income of $11.557 billion., this revenue accounted for 92.6% of the total revenue, and the company’s global market share was 7.63%, which was slightly lower than that of Weidaxin. The brokerage income of these two companies is above 10 billion, and they are the only two companies on the list whose income exceeds 10 billion US dollars.

Wei Lai Tao Yue’s brokerage income in 2022 was $7.781 billion., accounting for 87.8% of the total revenue, and its market share in the world is only 5.14%, which is about half that of the first-place Vida letter.

As a company with strong development momentum, Gallagher’s brokerage income is second only to Weilai Taoyue, reaching 7.355 billion US dollars, with a global market share of 4.86%.

Among other companies on the list, companies with brokerage income of more than $3 billion include Acrisure, HUB and Lockton, which are $3.823 billion, $3.49 billion and $3.205 billion respectively. Alliant, Truist Insurance Holdings, AssuredPartners, USI Holdings and Brown &Brown have brokerage incomes ranging from 2 billion to 3 billion dollars, with brokerage incomes of 2.954 billion dollars, 2.509 billion dollars, 2.363 billion dollars, 2.343 billion dollars and 2.322 billion dollars respectively.

Judging from the compound growth rate from 2020 to 2022, basically the growth of insurance brokerage companies is considerable, and all of them have achieved positive growth. Among them, the highest compound annual growth rate was contributed by Howden Group Holdings, reaching 55.2%, which also promoted the company from the previous lower position to 13th place. Another company with a considerable growth rate is Acrisure, with a compound annual growth rate of 40.5%. However, considering the gap between its economic income scale and the previous one, it is estimated that it will not affect the ranking within one or two years. Except for a few head companies, the compound annual growth rate of the remaining companies is between 10% and 25%, which highlights the development of the brokerage market.

For several head companies, the compound annual growth rates of VITEX and Aon are 8.2% and 6.3% respectively. Considering their business scale, such growth is normal and represents the healthy development of the company’s business. However, it should be pointed out that Weilai Taoyue is the only company on the list with a negative compound annual growth rate, which is estimated to have a great relationship with the sale of the business after the company merged with Aon in the previous two years.

As can be seen from the following figure, basically,The business of insurance brokerage companies basically revolves around risk management, welfare, retirement, reinsurance, etc., and is essentially involved in more in-depth business links such as insurance risk control and product design., through their own professional knowledge accumulation, to provide added value for insurance companies.

The following is the detailed business situation of some companies.

Gallagher: risk management, consulting

Although not well-known, Gallagher is the second largest insurance brokerage company after the first three. In recent years, the brokerage income of this company has also increased rapidly, which greatly exceeds the momentum of Wei Lai Tao Yue.

Gallagher has served many industries, including aerospace, architecture, energy, shipping, higher education, real estate, religion, and community for the aged.

In the insurance industry, some solutions provided by it include alternative risks and self-insurance, casualties, claims settlement, commercial guarantee bonds, construction bonds, credit and political risks, crisis resilience insurance and consultation, network, data and analysis, workers’ compensation and so on..

Taking alternative risk solutions and self-insurance solutions as examples, Gallagher provides them through its wholly-owned subsidiary ARTEX, helping customers around the world in the fields of insurance and self-insurance management, project and facility management, insurance-related securities (ILS) and structured transaction management. Some specific service arrangements include:

Group exclusive insuranceGroup self-insurance provides insurance for the risks of a number of unrelated companies, each of which owns a small part of the insurance company.

Core exclusive insuranceAs a growing field in the exclusive market, core exclusive insurance allows the parent company to isolate risks into different accounts.

Self-insurance leaseThis kind of arrangement allows enterprises to flexibly join established or sponsored exclusive plans and share profits with other companies, but they don’t have to invest so much money in advance.

Medical stop lossSelf-funded plan to provide large employer pricing and risk management services for medium-sized companies.

Alliant: risk management, employee benefits and reinsurance

Alliant is one of the top five commercial retail insurance brokers in the United States.. The company’s business includes risk management, employee benefits and reinsurance. In terms of risk management, its business covers many industries such as agriculture, aerospace, construction, network, energy and shipping, and some risk solutions provided include claims settlement, safety and loss control, trade credit and so on.

In terms of employee welfare, it provides various solutions such as welfare strategy, health and productivity, global manpower consultation, employer technical consultation and stop loss.

Compared with foreign countries, the development of domestic insurance intermediary market is not smooth.

All along,Due to the large number of business maps and different development, the problem of "multi-scattered" development has long existed in the field of insurance intermediary. Therefore, the closure and retreat of traditional institutions have always existed..

According to the data of beijing business today. com, as of January this year, the local banking and insurance regulatory bureaus cancelled or planned to cancel 1,870 insurance intermediaries’ licenses for concurrent insurance agency business, of which 1,816 insurance intermediaries’ licenses were cancelled, and 43 insurance professional institutions and insurance companies’ mutual agency licenses were cancelled; Insurance intermediaries in the automotive sector still account for the bulk.

However, it is worth noting that with the entry of new participants, the overall domestic intermediary market is also improving. Although no company has entered the top 15 in the world in terms of revenue scale, with the blessing and application of new models and technologies, the power of the overall intermediary is also strengthening.

Specifically, listed Fanhua, Shuidi and Huixuan all performed well in the first quarter.. In the first quarter, the operating income of Fanhua Holdings was 830 million, a year-on-year increase of 21%; The operating profit was 60.355 million yuan, a year-on-year increase of 193%. From the perspective of premium income, Fanhua Holdings achieved a total premium of 4.44 billion yuan, a year-on-year increase of 29%, far exceeding the average growth rate of 8.9% in the industry. Among them, the new single premium scale was 850 million yuan, up 51.4% year-on-year, and the renewal premium was 3.59 billion yuan, up 24.6% year-on-year.

Similarly, in the first quarter, the net operating income of each business module of Shuidi Company was 606 million yuan and the net profit was 49.73 million yuan. In the insurance-related business, Didi Bao completed the first-year premium of 1.692 billion yuan in the first quarter, an increase of 6.3% over the previous quarter. As of March 31st, 2023, Shuidi Company had provided 876 insurance products for customers.

Looking at Huixuan, in the first quarter of 2023, Huixuan’s premium, revenue and profit all achieved double-digit growth compared with the previous quarter. Among them, Huixuan platform contributed a total premium of 1.93 billion yuan, an increase of 33.4% from the previous month; The total revenue was 300 million yuan, up 15.7% from the previous month; The net profit was 18.414 million yuan, an increase of 30.3% from the previous month.

While the new force of insurance intermediary has made steady progress, companies such as head insurance intermediary Mingya and Datong have also made rapid progress in recent years. In terms of data, Mingya achieved a scale premium of 14.7 billion yuan in 2022, including a new single premium of 7.424 billion yuan; In 2022, Fanhua realized a total premium of 12.78 billion yuan, a year-on-year increase of 10.4%.

These data and growth show that the domestic insurance intermediary market is also breaking the original chaos, developing in an orderly and positive direction through the adjustment and reconstruction of business model, introducing new forces and adding new technologies. In view of this, we also expect the domestic insurance intermediary to develop better.

Looking at the top 15 list of global insurance brokerage companies, we can see that,Basically, the development of foreign brokerage companies presents two characteristics: merger and specialization.. To a certain extent, these two trends influence each other and complement each other, helping various brokerage companies to build a moat of business.

The merger and acquisition of insurance brokerage companies has become the norm in the industry.

According to data released by Chicago investment bank and financial consulting firm Optis Partners LLC,In the first quarter of 2023, there were 158 mergers and acquisitions between insurance agents and brokerage companies, down 17% year-on-year, the lowest level since 2019.7% lower than the five-year average transaction volume.

The reasons for the lower volume of M&A transactions include the rise in interest rates and the restrictions imposed by the uncertain economic situation, which led some active buyers to slow down M&A transactions. However, it should be pointed out that M&A transactions have been going on.

The data expenditure of Optis Partners LLC, the most active buyer in the first quarter was BroadStreet Partners Inc, which made 14 mergers and acquisitions, followed by Inszone Insurance Services LLC and Hub International Ltd, with 10 transactions each; World Insurance Associates LLC conducted 9 transactions, while Risk Strategies Co conducted 8 transactions.

Among them, Arthur J. Gallagher & Co is the most active listed brokerage company. Although Optis Partners LLC pointed out that the company announced 7 transactions in the first quarter, we can see from its official website that there were 10 M&A transactions, the details are as follows.

As can be seen,One of the characteristics of these M&A targets is that they have been deeply involved in some relatively small and unpopular insurance and risk management fields for many years.. For example, Anderson Benson is a retail insurance broker and risk management company, with expertise in entertainment niche and expertise in hotels, buildings, transportation and private customers all over the United States; AT Squared Holdings Limited is an insurance broker specializing in the field of education in the UK. Besides providing services for independent schools and universities, it also pays special attention to continuing education.

Through these mergers and acquisitions, the brokerage company itself can quickly expand into different fields, and quickly gain a foothold in a certain field through the professional skills of the acquisition target, which is the fundamental significance of mergers and acquisitions. Of course, on another level, mergers and acquisitions can also rapidly expand the business map of brokerage companies and expand their geographical coverage.

The so-called specialization means that brokerage companies provide solutions to solve their business difficulties and pain points for enterprises, individuals and various institutions through their own professional knowledge accumulation and technical empowerment in risk management and consulting services..

Looking at the list, although some large insurance brokerage companies often conduct business in multiple markets around the world, forming the current volume, there are also some companies that have only been deeply cultivated in some markets in the United States and have developed into global Top insurance brokerage companies. Therefore,Insurance brokerage companies are bound to develop in the direction of specialization and diversification. They should not only have the ability of professional risk management and risk prevention in a certain field, but also need to cultivate in many fields to form their own core competitiveness.. As for China, which is the second largest insurance market in the world, we also look forward to the emergence of a world-class insurance intermediary company in China, which will clear the name of domestic intermediaries and lead the way for market development.

　　　　　　　　Last week, the mainland box office closed at 609 million yuan, which was about 22% lower than the previous week. Relay became the overlord last week, winning 64.72 million yuan at the box office on the first day, exceeding expectations; Another new film only received 16.03 million yuan on the first day of painting. Although this sci-fi film has a good reputation in North America, it has been cold in China. Although "Ace Agent 2" was attacked by two new films on Friday, it easily overtook "Blade Runner 2049" the next day and won the second place in a single day. By Sunday, the cumulative box office of the film had exceeded 400 million.

　

From October 23rd to October 29th, there were 1.82 million screenings, and the number of people watching the movie was about 20.31 million.

　

Global Storm’s box office exceeded expectations, and the popularity of disaster films continued unabated.

　　　　　　　　

　　　　　　　　As the only imported disaster film this year, according to the film’s publicity, "Global Storm" cost as much as 120 million US dollars, equivalent to about 800 million yuan. When the film was released in North America, the box office was bleak, and the reputation was not good. The freshness of rotten tomatoes was only 13%, but in China, it was the opposite situation. The Global Storm captured 64.84 million yuan at the box office on the first day, taking 51.5% of the market share on that day. Successfully won the weekly box office champion.

　 　 　 Stills of the movie Global Storm

　　　　　　　　

　　　　　　　　Recalling that the last imported disaster film was released in 2015, the audience had a certain demand for watching disaster movie. The arrival of Global Storm, a pure disaster film, really met the needs of mainland audiences. Although the film can’t be compared with the one released in 2009 in terms of production and box office, its three-day release at the top of the single-day box office list also proves that China audiences like disaster films.

　

The box office was forced by the street to be criticized by 3 D.

　　　　　　　　Compared with Global Storm, another newly released film, Blade Runner 2049, did not perform very well at the box office. The film scored 8.5 in IMDB, and the freshness of rotten tomatoes was 88%. Such a sci-fi masterpiece with excellent reputation did not perform well in the world, and it was even worse in China. It only earned 16.03 million yuan on the first day of painting, accounting for 12.74% of the box office.

　

　Stills of the movie Blade Runner 2049

　　　　　　　As a sequel to blade runner released in 1982, most audiences can’t understand the plot design in Blade Runner 2049, and the film has a slow pace and no impressive climax, which inevitably makes the audience feel boring. In addition, the film was shot with a 2D camera, and it was forced to be converted to 3D later, which caused some picture distortion and insufficient light contrast, and the 3D version shown in the cinema also made many people criticize.

　

Break 2.15 billion 683 billion and end successfully.

　　　　　　　　The newly released horror film has assembled high-quality film companies such as Louis Koo, Chilam and Charlene Choi. Although there is some controversy about word of mouth, it also got nearly 30 million box office in the first week, ranking sixth. "Shameful Iron Fist" broke through 2.1 billion box office last Saturday (28th), and overtook the new film "Blade Runner 2049" in the weekly box office list. The single-day box office remained at about 10 million a day for nearly four weeks, with a stable trend and a double harvest in word of mouth and box office. In addition, three months after its release, Wolf Warriors 2, the top box office winner in mainland film history, ended successfully with a cumulative box office of 5.683 billion yuan on the 28th.

　　　　　　　　Due to the loss of a large number of films by the new film, the single-day box office on Friday fell by about 30% month-on-month. Although the film failed to surpass the previous film in word of mouth, the cumulative box office in the mainland has reached 420 million yuan, and there is still a chance to surpass the first box office of 480 million yuan.

　　CCTV News (Reporter Chen Xin Wang Yuxi):The recent popularity of a film and television drama has once again attracted the attention of the group of "North drift".

　　In the play, in order to realize his acting dream, the hero came to Beijing with his bare hands, lived in a dark basement, lived on instant noodles and canned food, and ran around every day for an interview with the crew … … However, after ten years down and out, all I got was moving from the basement where I couldn’t see anything to the basement where I could see my feet. The best role I played was just a faceless "lion essence".

　　Video screenshot

　　The experience of the hero made the audience who followed the drama cry, and the topic in the play # Should I go after drifting in the North for ten years # also appeared on the hot search, which triggered a hot discussion among netizens. Many people who have experienced "drifting north" have also seen their own shadow more or less in it.

　　What can I get for drifting in the North for many years? Did you get ahead? Is there a moment when you want to escape?

　　"From the capsule-youth hostel-basement, I don’t know if I will drift down."

　　Yu Meng, a handsome young man from Xuzhou who has been in Beijing for more than 8 years, is engaged in public welfare activities. He said bluntly that he came to Beijing because he was lovelorn, and it happened that his relatives in Beijing called to let him come, which was an escape.

　　Not long after he arrived in Beijing, the accommodation conditions went downhill: express hotel-space capsule-youth hostel (one room for 10 people)-basement.

　　While staying in the hostel, he enthusiastically told the unfamiliar roommate the computer password on the phone when he was at work, and then he never found his beloved notebook again. Yu Meng, who had no money, had to find a cheap basement to live in.

　　"I haven’t lived in the basement before, but I didn’t know it was wet and damp until I lived there, and there was a musty smell everywhere. Why live in the basement? " Yu Meng said with a wry smile, "I don’t have much money, and I don’t want to ask my family for it."

　　"You can stay in a better hotel when you are on a business trip. As soon as you get back there, you feel like you have fallen from heaven to hell." Loneliness and inferiority crept into his body. Yu Meng once suspected that he had depression. He broke contact with his friends and rarely talked to his colleagues. After work, I always like to "stay" outside a cafe in Joy City. "I don’t want to go back to that boring and lonely place."

　　After getting alopecia areata and losing a piece of hair, Yu Meng decided to move. He found a rental house with a good environmental location, with a monthly rent of 2,000 yuan. After signing the contract and paying a deposit of 5,000 yuan, Yu Meng told his mother the "good news" with joy, but he didn’t want to be drenched with cold water.

　　"My mother didn’t advise me to live in such an expensive house and advised me to eat more bitterness. After all, I still have to pay back the mortgage of that house in my hometown, and I have to get more than 2,000 yuan a month, and my salary is not enough. " After calling, Yu Meng cried bitterly for a few minutes.

　　However, what made Yu Meng collapse even more was that he met a black intermediary, and the deposit finally hit Shui Piao. Yu Meng didn’t want to find another house, and continued to live in the basement for more than a year.

　　"Fortunately, I am a Xiaoqiang who can’t be killed. I survived that difficult time."

　　Today, Yu Meng lives in a clean and tidy shared room of more than 10 square meters, with a monthly rent of more than 2,000 yuan. The residential environment is good and it is close to the place where he goes to work.

　　In Yu Meng’s view, Beijing is a place that people love and hate.

　　"In recent years, my horizons have broadened a lot, and my living standards have improved, but my happiness is not high and I have no sense of belonging. I don’t know if I will continue to drift. If you are busy, you will forget the rest; Once I am free, I feel ‘ Empty, lonely and cold ’ . I have thought about fleeing and returning to my parents and brothers many times, but I am not willing. If there are no more people or things in Beijing that make me worth staying, I will go back to Nanjing to start a business. After all, I am closer to home. "

　　"Beijing is like a ‘ Love rat ’ I gave it my best youth, but it refused to give me a home. "

　　In her fifth year in Beijing, 28-year-old Li Meng sent a message to her mother: I want to quit my job and go home!

　　She felt that she was pushed to the limit by her work.

　　Appear bleary-eyed in the crowd at the morning rush hour of the subway every day. It takes an hour and a half to get to the unit by changing the subway three times and taking two bus stops. Waiting for her, there are endless planning cases and PPT. When there is a big event, it is normal to work overtime all night.

　　"I feel that my body and mind have been devastated." Li Meng said.

　　And let Li Meng made up his mind to go home, it is more than 12 o’clock one night, Li Meng was awakened by a hard knock on the door and asked who it was. No one answered, but he knocked harder and twisted the doorknob from time to time. Li Meng felt that her brain was blank. She ran to the kitchen and got a kitchen knife, and called 110. "I don’t know how long it took. The knock on the door outside the house stopped, and the property sent someone. I didn’t find anything unusual. They said that someone might be drunk and admit the wrong door."　 　

　　Li Meng never fell asleep again, and stayed alone in the studio of the old residential area outside the Fifth Ring Road, waiting for dawn. "It’s nice to turn to my friends in my hometown to bask in my children and husband, and they laugh so happily! Look at me again, poor thing! "

　　Early the next morning, she knocked down the WeChat that fled Beijing.

　　"At that time, I felt that Beijing was like a ‘ Love rat ’ I gave it my best youth, but it refused to give me a home. " Li Meng can’t remember where she saw this sentence, but she felt that she spoke her inner feelings very accurately.

　　However, Li Meng returned to his hometown in Northeast China for six months, but failed.

　　In my hometown, I can go to all places within an hour, and there are few people on the street after 9 pm. There are no endless exhibitions, plays and lectures, but there are many relatives and classmates who take pleasure in comparing with others. "In their eyes, they are not married at the age of 27 or 28; Do not want to take an examination of public institutions and civil servants; Get married and don’t have children. Think about Dink … … These behaviors are heterogeneous. "

　　Li Meng also tried to work in an Internet company in her hometown for two months, but she found that the employees’ overall business level was not high, and everyone’s ideas were conservative. They were used to the fast-paced working life in Beijing, but they didn’t adapt to it when they went home.

　　"Although Beijing has abused me thousands of times, I can only treat it like first love. After all, it really gave me an experience and vision that my hometown could not give. "

　　During these years in Beijing, Li Meng likes to go to the Film Archive and livehouse when he is free.

　　In this way, Li Meng once again returned to Beijing. She interviewed a large-scale real estate company to do event planning, and most of her team were young people. "The atmosphere here is more relaxed and free, you can meet people who used to only see in the news, and you often have the opportunity to go abroad for business trips. Such platforms and resources are unattainable in their hometown. "

　　Drawing lessons from previous renting, Li Meng "collected" a roommate online. The two girls rented a small two-bedroom apartment together. Although the monthly rent is twice as expensive, the community is new, with 24-hour security and safety.

　　Now, Li Meng, who has been drifting in the North for eight years, feels that she is more mature than before. "Difficulties always have to be experienced. In Beijing, more blood and tears mean more growth. I feel that my horizons are more open. My horizons are not the same as going to high-end places, using high-end products and living a luxurious life. Instead, I have the opportunity to contact the world more, embrace the world, and gain mature and diversified thinking. Perspective, critical thinking, and strong empathy are more important to me. "

　　"I was in debt for 300 thousand in the second year of my work, but I never thought of leaving Beijing."

　　Darren Liu, a young town man from Sichuan, made up his mind very early that he must go to Beijing in the future. "When I was very young, my parents went out to work, and only my grandfather took me at home. At that time, my grandfather told me that if I went to Beijing to study, I would be able to get ahead."

　　It is said that the harder you work, the luckier you will be. Darren Liu was admitted to a well-known university in the capital as he wished. Before graduating from university, he got a postgraduate degree. At the age of 24, he worked in the financial system and got a Beijing hukou more smoothly.

　　"When I got my hukou, I felt that I was finally going to get a foothold in Beijing. At that time, the house price had not risen. I figured how I could get a down payment on the house in a few years." However, it wasn’t long before Darren Liu found that the house seemed to be too late for him to save money to buy.

　　"When I went to work one day, a message popped up on the Internet saying that the average house price in Beijing’s Fifth Ring Road had reached 30,000. My first reaction at that time was that this was false news." Although he was dubious about the news, Darren Liu immediately made an appointment with a real estate agent. After work that day, he hurried to see the house.

　　Three months later, Darren Liu selected a small apartment outside the South Fourth Ring Road with a down payment of 500,000 yuan. My parents in my hometown took out all the savings of 200 thousand, but it was a far cry from it. Darren Liu had to bite the bullet and borrow from his colleagues, predecessors and leaders. The taste of borrowing money is not good, but Darren Liu can only do this: "If I miss this opportunity, I will never want to buy a house in Beijing in my life."

　　In the second year of work, 25-year-old Darren Liu was burdened with a foreign debt of 300,000 yuan, providing a monthly mortgage of nearly 10,000 yuan. This once "other people’s children" lived in Beijing with extra anxiety: working overtime desperately to change their performance, for fear that they would be eliminated by work if they relaxed; Rent a small bedroom of seven or eight square meters, and there is basically no extra space outside the bed; There is not a penny left, and when it is the most "bleak", you have to find one yuan and fifty cents in the piggy bank to collect lunch money; I don’t go out on weekends and holidays, and I have been rejected by my girlfriend for being stingy, boring and uninterested for countless times.

　　"Who doesn’t want to live a quality life, but you can’t be fake and exquisite without money." Although helpless, Darren Liu understands that it is not easy for a child who lives in a foreign country and has an ordinary family to really establish himself in Beijing. However, the thought of harvest, Darren Liu still feel particularly hopeful.

　　Darren Liu said that the happiest thing when renting a house is that his girlfriend will cook him a simple lunch on weekends.

　　In 2019, it was the 13th year that Liu Di came to Beijing. At the age of 31, he moved to a new unit and his salary tripled. Married his girlfriend and moved into a new home. For so many years of living in the North drift, Darren Liu said: "Although it is very hard, I have never given up. If I hadn’t stayed here, I wouldn’t have forced myself to grow up so fast. Stay in Beijing, but I feel practical. "

　　Darren Liu always disliked that the word "drifting north" was endowed with too much "desolation". "Beijing, though bigger and more crowded than other cities, also means more opportunities and more choices. The world of adults is not easy anywhere. drifting north is just a choice of life. Since you choose this life, you have to bear all the things it gives you. " (At the request of the interviewee, all the articles are pseudonyms.)
