This is the 2329th article of Da Yi Xiao Hu.

Up to now, there have been three epidemic outbreaks caused by coronavirus in this century, namely, Severe Acute Respiratory Syndrome (SARS) in 2002-2003, Middle East Respiratory Syndrome (MERS) that began to spread in 2012, and novel coronavirus (COVID-19) that appeared at the end of 2019. China is a country with severe disasters in SARS and this time in novel coronavirus.

First, what is coronavirus?

Coronavirus exists widely in nature. Coronavirus was first isolated from chickens in 1930s, and it was isolated from human nasal wash more than 20 years later by scholars and named B814 virus. Later, scholars made an in-depth study of the virus from its morphology, and found that the envelope of the virus had a spinous process like a corona and a king’s crown, so the coronavirus was named from this. Its natural hosts are mainly vertebrates, and people, cows, pigs, cats and bats are all its natural hosts.

Coronavirus is slightly spherical in shape, with a diameter of 80-160nm. The "crown" on its surface is a fiber process of 12-24nm, and the end of the fiber process is also spherical. The envelope of the virus consists of two layers of lipids, with membrane protein M and fibrillary protein S interspersed between them, and some coronaviruses also have hemagglutinin glycoprotein HE. The interior of the virus is composed of RNA and nucleocapsid protein N, showing a spiral structure.

S protein is the key protein of coronavirus-infected cells, which contains host cell receptor recognition sites and is the main determinant of virus virulence. M protein is the main protein responsible for virus particle assembly. N protein is closely combined with viral RNA, which can protect viral genomic RNA through spiral stacking and encapsulation. At the same time, it can delay the growth of infected cells and make them stay in the division period for a longer time, so that viral RNA can be translated to the greatest extent. HE protein plays a key role in the formation of virus particles.

As far as virus classification is concerned, coronavirus belongs to single-strand positive-strand RNA virus, which indicates that the genetic information of coronavirus is carried by RNA, and the cloned progeny virus has a high mutation rate. After entering the host cell, it directly uses ribosomes in the host cell to produce protein needed for virus replication without transcription. Coronavirus can kill cells, thus damaging various organs, and persistent infection occurs simultaneously with acute infection, mainly attacking gastrointestinal tract, respiratory tract and nervous system.

Second, the coronavirus that humans have fought.

Before SARS, it was thought that only two kinds of coronaviruses could cause human infection. At present, there are seven kinds of coronaviruses that can infect humans, including highly lethal coronaviruses, severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV) and novel coronavirus virus (COVID-19).

The common feature of coronavirus is that it is generally sensitive to heat, and it is moderately stable in a suitable maintenance solution at 4℃, and can be stored for several years at -60℃. With the increase of temperature, the virus resistance decreases. Coronavirus is acid-resistant and alkali-resistant, and sensitive to organic solvents and disinfectants such as alcohol and ether.

The symptoms of coronavirus infection are mostly similar, mainly fever, chills, cough and so on. The main routes of transmission are droplet transmission and contact transmission.

1. SARS coronavirus (SARS-CoV)

Severe acute respiratory syndrome (SARS) was caused by SARS-CoV. By July 2003, it had spread to 24 provinces, autonomous regions, municipalities directly under the Central Government and 28 other countries in China. A total of 8096 clinically diagnosed cases were reported worldwide, and 774 cases died. Nearly 20%~30% of the patients needed mechanical ventilation due to respiratory failure, and the mortality rate was 9.6%. Epidemiology in many provinces and cities showed that the mortality rate increased with age, mostly over 60 years old. Its incubation period is within 2 weeks, usually 2~10 days. The population is generally susceptible and has a strong epidemic degree. The main onset age is 20-30 years old. The source hosts may be bats and civets. The transmission routes are mainly from person to person: droplet transmission in close respiratory tract, aerosol transmission and hand-to-hand contact transmission; Animals and people: civets/bats ~ people (possible). SARS-CoV has the general characteristics of coronavirus, but it is not a mutant of other known coronaviruses, nor is it a recombinant of known coronaviruses. SARS-CoV infects lung epithelial cells, and its S protein binds to angiotensin converting enzyme 2(hACE2) receptor, which invades and replicates in vivo. Because hACE2 is mainly in the lower respiratory tract, the symptoms of the upper respiratory tract are lacking, and the virus often peaks when hospitalized, which is easy to cause nosocomial infection of the lower respiratory tract.

2. MERS coronavirus (MERS-CoV)

Middle East Respiratory Syndrome (MERS) was caused by MERS-CoV, which was first confirmed in Saudi Arabia in 2012, affecting 27 countries and regions around the world, with a mortality rate of about 35%. According to statistics of a case, the mortality rate increases with age. The mortality rate is 39% in people younger than 50 years old and 75% in people over 60 years old. The longest incubation period is 14 days, and the population is generally susceptible. The median age of onset is 49 years old. Source host: it may be camel or bat. Transmission route: animal and human: dromedary ~ human (possible); People: Close contact. The infection site is epithelial cells in the lung, which causes explosive nosocomial transmission, and has obvious gastrointestinal symptoms and renal failure. It mainly binds to dipeptidyl peptidase 4(DPP4) in the lower respiratory tract, gastrointestinal tract and kidney, and there is no mutation that enhances human infection.

3. 2019 novel coronavirus (2019-nCOV)

Novel coronavirus was caused by 2019-nCOV. From mid-December 2019 to the beginning of 2020, 59 cases of unexplained pneumonia were reported in Wuhan, and similar cases were found in other regions and countries. On January 7, 2020, it was initially identified as "novel coronavirus", and on January 12, the WHO named the virus 2019-nCoV. Up to now, more than 70,000 cases have been diagnosed, and more than 2,400 cases have died, with a mortality rate of about 3.1%. It has spread to most provinces and cities in China and nearly 30 countries. The transmission routes may be droplet transmission, contact transmission and aerosol transmission. The incubation period is 1~14 days. At present, the source host may be a bat. Shi Zhengli’s team from Wuhan Institute of Virology has found that its genome is 79.5% identical to SARS-CoV and 40% similar to MERS-CoV. 2019-nCOV, like SARS-CoV, invaded by combining with human angiotensin converting enzyme 2(hACE2), infecting respiratory system, gastrointestinal tract and testis, affecting heart function and liver function. According to the current data, compared with SARS and MERS, it is more contagious and the mortality rate is not as high as the first two.

Third, actively protect against novel coronavirus

Personal protection requires frequent hand washing and hand hygiene. Cover your mouth and nose with paper towels when coughing or sneezing, which can effectively prevent the spread of droplets. Wear masks in public places, avoid contact with animals with unknown health conditions, and reduce the trading of live birds and wild animals.

At present, various industries have started to return to work. For the office, everyone should actively declare their health. If there are suspicious symptoms such as fever, fatigue and cough, it is recommended to seek medical advice in time, avoid going to work sick, strengthen ventilation and ventilation in public areas, clean and disinfect public areas and public goods regularly, keep the environment clean and hygienic, keep a proper distance when there are many people in the unified office area, and reduce centralized meetings by video and teleconference.

We must adhere to the general tone of striving for progress while maintaining stability, maintain strategic strength, adhere to the supply-side structural reform as the main line, continue to expand effective demand, focus on revitalizing the real economy, actively respond to external challenges, prevent and resolve potential risks, guide and stabilize social expectations, and scientifically and comprehensively promote steady growth, promote reform, adjust structure, benefit people’s livelihood, and prevent risks to ensure stable and healthy economic operation.

Wu Zhenyu, the two film emperors’ rival in love, spoiled Sun Honglei on the spot.

　　"The Warring States" is based on the unprecedented tragic hegemony of the Seven Heroes of the Warring States in history, and describes the epic legend that two legendary militarists, Sun Bin and Pang Juan, evolved from close brothers to enemies and finally fought a decisive battle on the battlefield. Sun Honglei plays Sun Bin, who is kind-hearted, and Wu Zhenyu plays Pang Juan, who is fierce. The fate of the Warring States troubled times makes the two film emperors struggle in the play and become rivals in love. When it comes to the conflict between love and friendship, Sun Honglei faltered and finally reluctantly said, "Brothers come first, love comes second." Wu Zhenyu said helplessly, "I choose beauty, but beauty doesn’t choose me. When I chose my brother, my brother left me. "

　　"I think Sun Bin is wandering between a genius and an idiot. He has great talent in military affairs, but he doesn’t even have the basic ability to live in life. This time it’s more risky, and I hope it won’t thunder everyone." In order to experience the role, Sun Honglei also came to Sun Bin’s hometown and made a trip. "Bitter risks, cross the rubicon, deviance, etc. are all strategies used by Sun Bin in the movie." Sun Honglei said that the film shows the interlocking military strategies in a suspenseful way.

　　Although Wu Zhenyu has always been famous for playing a role with strange personality, he gently spoiled Sun Honglei at the scene that day. At that time, the host asked Wu Zhenyu to call Sun Honglei in three identities: brother, rival in love and enemy. Wu Zhenyu was shy and shouted, "Mmm!" Make a scene.
　

The Xingtu brand, which debuted at the 2017 Frankfurt Motor Show, can be regarded as a new force in the autonomous high-end field. It has three models: LX, TX and TXL, covering the mainstream compact SUV and medium-sized SUV segments. In order to achieve further upward breakthroughs in the brand and cater to its own high-end positioning, Xingtu planned a medium and large SUV model VX very early, but due to various reasons, the release time has been repeatedly delayed, which has whetted consumers’ appetite. Finally, the new car is determined to be officially launched on March 18, 2021, and the Chinese name Lanyue has been announced.

As the fourth SUV model launched by the Xingtu brand, Lanyue is no longer named with simple English letters, indicating that the new car will have a unique positioning. Due to the largest size in the Xingtu brand, and the use of exclusive M3X architecture and a large number of advanced technologies, Lanyue undoubtedly plays the role of family flagship. The listing of Xingtu Lanyue launched a total of 6 models, respectively equipped with the group’s latest 1.6T and 2.0T turbocharged engines, priced at 16.89-22 9,900 yuan. For a high-end mid-to-large SUV, consumers will definitely value its comprehensive configuration performance when purchasing, so which of the 6 models is more cost-effective?

Brief description of the model

Lanyue is based on the latest M3X Mars architecture of the Xingtu brand. Compared with previous products, Lanyue has a comprehensive improvement in safety and technology. Of course, as a family flagship model, Lanyue also shows a good temperament.

The appearance of Lanyue restores the design of the Xingtu VX concept car to the greatest extent, and the overall shape is slightly tough and full of futuristic atmosphere. The front face is more square, and the inside of the polygonal air intake grille is decorated with banner chrome, with large-sized headlights on both sides, which is full of momentum. The trapezoidal lower grille is wrapped in silver chrome decoration, and the fog lamp area on both sides also adds vent decoration, which looks more youthful and fashionable.

The side has the stable temperament of a medium and large SUV, and the straight waist line and wide eyebrows show a certain sense of strength. The tail shape is relatively heavy, and the through-type LED taillights play a finishing touch to the overall design. The reflector design on both sides echoes the fog lights on the front of the car. The bottom silver lower guard and chrome-plated double tail row add a sporty atmosphere.

The Lanyue series offers two sizes of rims, among which the entry-level Star Enjoy Edition and the three Star Yao Edition models are all in the 19-inch double five-spoke Y shape, and they are painted in black, which is full of sports. The tires are made of Magis Victra Sport 5 series products, which focus on sports and handling. The tire specifications are 235/55 R19; while the high-end Star Rui version and Star Zun version are equipped with 20-inch two-tone multi-spoke rims, which has a stronger design sense. The tires are made of Continental MaxContact MC6 series products, which have excellent safety and comfort. The tire specifications are 245/45 R20.

In terms of appearance color, Lanyue offers 5 body colors to choose from, namely meteorite gray, star track blue, Haoyue white, nebula purple, and phantom night black. The main color is star track blue, which shows a stable temperament without losing a sense of fashion. Haoyue white and phantom night black two colors are biased towards the style, while meteorite gray and nebula purple are obviously more personalized.

The interior design of Lanyue generally continues the family design style. The regular layout and a large number of horizontal lines effectively stretch the visual width. The full LCD instrument and central control screen use the mainstream dual-screen floating design, which has a strong sense of technology. In addition, as a high-end brand, Lanyue is also more particular about the materials used. The center console, front and rear door panels and other parts have added dark wood grain decoration, and the seats are also made of Meridian punched leather with diamond-shaped pattern design, creating a more luxurious atmosphere.

In terms of configuration, all Lanyue models come standard with full LED headlights, headlight height adjustment, keyless entry/start and other functions. In terms of multimedia, it is equipped with Lion4.0 Lion Zhiyun system, which supports FOTA cloud upgrade, remote start, GPS real-time car navigation, smart home interconnection, mobile phone interconnection/mapping Apple CarPlay and other functions. The high-end models are also equipped with L2.5-level automatic driving assistance system, including ACC adaptive cruise, FCW front collision warning, LKA lane keeping, TJA traffic congestion assistance and other functions.

In terms of power, Lanyue is equipped with the latest third-generation ACTECO engine, providing 1.6TGDI and 2.0TGDI engines, with maximum power of 197 horsepower and 254 horsepower respectively, and peak torque of 290 Nm and 390 Nm respectively. The transmission system is matched with a 7-speed wet dual-clutch gearbox and is equipped with a timely four-wheel drive system.

II. Vehicle configuration highlights and recommendations

The 290T two-wheel drive Star Enjoy Edition is an entry-level model for the whole series of Lanyue, priced at 168,900 yuan. Although the price is advantageous for a mid-to-large SUV positioned at the high end, a closer look at the configuration sheet shows that there are not many bright spots, which only meet the basic needs. First, the entry-level model is equipped with a 1.6TGDI engine. Although the maximum power is not much different from the 2.0TGDI version, the maximum torque is still 100 Nm apart. Secondly, in terms of frequently used lights and auxiliary driving functions, the entry-level model is only equipped with LED near and far lights, and does not provide the two practical functions of automatic headlights and adaptive near and far lights, which are currently more popular. In addition, the entry-level model only provides the rear radar and ordinary reversing image functions, and the lack of front radar and 360-degree panoramic images may affect driving or parking at narrow intersections. In terms of active and passive safety, the configuration performance of the entry-level model is not comprehensive enough. Not only is it not equipped with the L2.5 level automatic driving assistance system promoted by the manufacturer, but even the airbag only provides the front and side four configurations, and lacks the protection of the head airbag. In addition, in terms of seat configuration, the performance of the entry-level model is also quite decent. The seat is made of ordinary leather material, only the main driver’s seat is electrically adjusted, and it is not equipped with a practical waist support adjustment function, which greatly reduces the ride comfort. Of course, the entry-level model’s configuration performance in multimedia and air conditioning is still worthy of recognition. The whole system is equipped with a 12.3-inch central control display, and the commonly used navigation, automatic speech recognition, mobile phone interconnection, vehicle to everything and OTA upgrades are also readily available. Air conditioners are equipped with three-zone automatic air conditioners as standard in the whole system, and the rear row also provides a separate trend and control area. Considering the low power and configuration of the entry-level model, combined with its relatively affordable price, it is only suitable for consumers who have a small budget and do not have high requirements for power and configuration.

III. Difference analysis of recommended vehicle configurations

As a low-end model, the 290T two-wheel drive Xingyao version priced at 179,900 yuan is 10,000 yuan more expensive than the entry-level model. The added configuration mainly focuses on convenience and comfort, including front radar and 360-degree panoramic images, electric trunk with induction function, leather seats, lumbar support adjustment, front seat heating, driver’s seat memory, etc., which greatly improves the car experience. At the same time, the model has also been slightly upgraded for lighting multimedia, adding functions such as automatic headlights, facial recognition and the original driving recorder. But from the configuration and price point of view, the cost performance of this model is still OK. If you don’t care about the lack of 1.6TGDI engine power, then the 290T two-wheel drive Xingyao version is a good choice.

Compared with the two 290T models, the four 390T models not only have better power performance, but also have a higher overall configuration level. Especially in terms of active safety and lighting, the 390T models are equipped with L2.5-level automatic driving assistance systems, including ACC adaptive cruise, FCW front collision warning, LKA lane keeping, TJA traffic congestion assistance and other functions. In addition, the 390T models are also equipped with adaptive far and near light to improve night driving safety.

Among the four 390T models, the editor’s key recommendation is the 390T two-wheel drive Xingyao version priced at 188,900 yuan. On the basis of the configuration of the 290T two-wheel drive Xingyao version, in addition to adding the L2.5 level automatic driving assistance system, the HUD head-up display and adaptive far and near light functions are also added to further improve safety. Although some configurations are also reduced accordingly, such as front radar, front mobile phone wireless charging, waist support adjustment, etc., it has little impact on daily car use, and the value of the increased configuration is much higher than the reduced configuration, and the comprehensive cost performance is higher.

The overall configuration of the 390T four-wheel drive version is very close to the recommended model, the difference is only that it is equipped with a timely four-wheel drive system, and the price has also increased by 12,000 yuan. Considering that the timely four-wheel drive system has limited improvement in the actual performance of the vehicle, and the fuel consumption of the four-wheel drive model is relatively higher, if the car environment is mainly urban roads, then the 390T four-wheel drive version is also not recommended. As for the two high-end models, on the one hand, the price is relatively high, and on the other hand, the added configuration plays a more icing on the cake role. Including parallel assist, reversing car side warning, seat ventilation, 8-speaker SONY audio, steering assist light, exterior rearview mirror memory, exterior rearview mirror reversing automatic down, automatic anti-glare interior rearview mirror, negative ion generator, etc. These configurations can certainly enhance the luxury temperament of the vehicle, but they are not very helpful for daily use. Therefore, from the perspective of comprehensive price and various configurations, the 390T two-wheel drive Xingyao version has a more obvious cost-effective advantage among all models of Xingtu Lanyue, and it is recommended to give priority when purchasing.

As a top actress in the entertainment industry, Yang Ying’s every move has attracted much attention. However, as her popularity continues to rise, so does her responsibility. As a public figure, her words and deeds are magnified, as if she is enjoying the benefits of starlight, but also forgetting the self-discipline and norms that a top star should have.

The recent Crazy Horse episode has put Yang Ying’s image at an unprecedented risk. What was originally a niche entertainment experience has entered the public eye because of Yang Ying’s visit. The incident has raised questions not only about Yang Ying’s personal character, but also about her sense of responsibility as a public figure. Unfortunately, this time she does not seem to have delivered satisfactory answers.

In the turmoil caused by the Crazy Horse show incident, Yang Ying’s social account was banned for up to three months. This is undoubtedly a heavy blow for Yang Ying. In the digital world, this is almost equivalent to disappearing from the public eye. Fans are thrown into confusion and unease for a while. After all, in this era of face-seeing, no exposure means being forgotten. However, this may be an opportunity to reflect and replan their own star path.

Despite the ban, Yang Ying has not completely faded from the public eye. Within a week, it was revealed that she was involved in the shooting of a magazine. Although this time her photo did not appear on the cover, it became the inside page, a low-key approach that was both cautious and revealed her determination not to give up. After the halo faded, Yang Ying chose a more restrained and low-key way to show the world that she is still trying to move forward.

Once upon a time, Yang Ying’s acting skills were widely criticized, but her performance in variety shows undoubtedly gave her a lot of credit. Now, although the Crazy Horse show incident has caused her reputation to drop to the bottom, she has not given up. Amid the public ridicule, Yang Ying seems to be answering the question of "soft ban" with action. She is no longer the actress who only shines under the spotlight, but quietly works behind the scenes to prepare for her next appearance.

During this time, she learned how to grow in the trough and how to find a way out in the controversy. Her transformation has shown us a more mature and confident Yang Ying. Although the road ahead is not smooth, she is ready to face new challenges.

Today’s Yang Ying has stepped down from the position of a top star, but she is not far away from the entertainment industry. She began to try more roles and constantly push her comfort zone. Her performances also began to become more realistic and natural, no longer just superficial forms. Her efforts and persistence have allowed us to see a more comprehensive and in-depth Yang Ying.

Looking back at Yang Ying’s ups and downs in life, we see a growing and improving her. Although she has encountered setbacks, she did not give up but honed herself in the face of difficulties and continuously improved herself. Her story tells us not to give up easily even when facing difficulties. Only by persevering in hard work can we achieve success.

Let’s look forward to Yang Ying’s next role together as she continues to create her own brilliance in the entertainment industry!

Nongfu Spring, which has repeatedly said that there is no need to list, finally decided to list on the Hong Kong Stock Exchange. The company that mainly produces "a little sweet" mineral water has a financing scale of no more than 1 billion US dollars, but it is a high probability event that it will enter the 100 billion market value club after listing.

We carefully read the prospectus submitted by Nongfu Spring to the Hong Kong Stock Exchange and found that the company had mixed feelings.

Nongfu Spring "not bad money"

Nongfu Spring was established in 1996, and its founder Zhong Liangyi holds 87.4% of the shares. The company’s main business contributes about 95% of the total operating income. The main products include drinking water, tea beverages, functional beverages and fruit juice beverages, accounting for 60%, 13%, 16% and 10% of the revenue respectively. Among them, drinking water and fruit juice beverages have grown rapidly.

According to the prospectus, Nongfu Spring has maintained steady growth in the past three years. From 2017 to 2019, the income was 17.491 billion yuan, 20.475 billion yuan and 24.021 billion yuan respectively, with a compound annual growth rate of 17.2%. Nongfu Spring achieved net profit of 3.385 billion yuan, 3.612 billion yuan and 4.954 billion yuan in the past three years, with a compound annual growth rate of 21.0%.

In 2019, the comprehensive gross profit margin of Nongfu Spring was as high as 55.4%. Mainly due to the gross profit margin of 60.2% of the largest drinking water product. The gross profit margins of other categories such as tea beverages, functional beverages and fruit juice beverages were 59.7%, 50.9% and 34.7% respectively.

In terms of net profit, the net profit rate of Nongfu Spring rose to 22.8% in 2019, of which sales expenses accounted for the largest proportion of the three fees. Specifically, sales expenses accounted for 24.2% of operating income, and the most important ones were transportation expenses and advertising expenses, which were 2.53 billion and 1.22 billion yuan respectively, accounting for 10.5% and 5.1% of operating income, respectively.

In terms of cash, Nongfu Spring adopts the first payment and then the goods transaction method, and the book receivables are very small. From 2017 to 2019, the company’s net operating cash inflow was greater than the net profit of the year, especially in 2019, the net operating cash inflow was as high as 8.73 billion yuan. From 2017 to 2019, the book structured deposits were 2.04 billion, 3.60 billion and 200 million yuan respectively. The average interest rate earned was between 4.0% and 4.9%.

The sharp decrease in cash in 2019 was due to the concentrated dividend of Nongfu Spring up to 9.50 billion yuan before listing. Among them, the major shareholders received 8.20 billion yuan. Previously, although Nongfu Spring also had annual dividends, the amount was 2-300 million yuan. And the total financing of Nongfu Spring is only 1 billion US dollars.It is certain that Nongfu Spring did not choose to go public because of a lack of funds.

What is the valuation after going public?

Master Kong Holdings, the equivalent producer of mineral water in Nongfu Spring, has been listed on the Hong Kong stock market. In 2019, Master Kong Holdings’ beverage business contributed HK $39.70 billion to operating income, which was greater than Nongfu Spring’s operating income. But net profit was only HK $3.72 billion, far less than Nongfu Spring’s 4.95 billion yuan.

At present, the market value of Tingyi Holdings is 77.20 billion Hong Kong dollars, corresponding to the price-to-earnings ratio of about 20.8 times in 2019. It is estimated that the total market value of Nongfu Spring after listing is at least about 130 billion Hong Kong dollars. In fact, Nongfu Spring is better than Tingyi Holdings in terms of profitability and growth, and the market may give a higher valuation.

According to the prospectus, the drinking water market is still in a stage of rapid development. According to Nielsen’s forecast, it is still expected to maintain a growth rate of about 10% in the next five years. Compared with the beer and condiment market, the drinking water market has more room. Based on the high concentration of the drinking water market, it is also possible to produce a leader with a larger market value than Budweiser Asia Pacific (1876.HK) and Haitian Flavor (603288.SH) in the long run. The average price-to-earnings ratio valuation of beer in the Hong Kong stock market is 30-40 times. The average valuation of soy sauce and vinegar in the class A share market is more than 40 times. Based on this, we have predicted the market value of Nongfu Spring.

The troubles of Nongfu Spring

Although the situation is good, Nongfu Spring is not a smooth road.

First of all, the drinking water business depends on the source of water, and the bottleneck facing the long-term growth of Nongfu Spring is the limited source of water. According to relevant laws and regulations, units and individuals who directly extract water from natural resources (such as rivers, lakes and groundwater) need to obtain a water extraction license and pay a water resource fee. Enterprises need to extract water according to the approved annual water extraction plan. Moreover, mineral water has the dual attributes of water resources and mineral resources. The production of mineral water should also apply for a mining license according to law. In other words, the scarcity of water sources on the one hand helps enterprises to establish high industry barriers, and on the other hand restricts enterprises to expand production capacity. It is conceivable that with the development of the industry, there are fewer and fewer untapped water sources.

The situation of Nongfu Spring’s newly obtained water sources in recent years is not optimistic. At present, Nongfu Spring has a total of 10 water sources. The main production bases are still Qiandao Lake in Zhejiang, Changbai Mountain in Jilin, Danjiangkou in Hubei and Wanlv Lake in Guangdong, which were obtained before 2005. With the increase in environmental awareness, the water withdrawal from water sources obtained by Nongfu Spring in recent years has become smaller and smaller. In 2019, the newly obtained water withdrawal from water sources was only 504 thousand cubic meters per year. Although the approved water withdrawal from water sources currently owned by Nongfu Spring is much larger than the actual production capacity of the company, the company does not have the problem of insufficient water withdrawal in the short term. However, products concentrated in water sources in Zhejiang, Guangdong, Jilin and Hubei are also limited by the transportation radius.

Nongfu Spring has less water sources that can produce mineral water, which is not conducive to product upgrades in the future. In addition, the average ton price of Nongfu Spring drinking water has declined for two consecutive years, the company explained, because of the increase in sales of large-packaged drinking water with lower unit prices. In the short term, Nongfu Spring may face the risk of lower gross margins.

Due to the scarcity of domestic water sources, Nongfu Spring has begun to go overseas. Nongfu Spring has acquired Otakiri Springs, a New Zealand bottled water company. The prospectus revealed that Nongfu Spring will look for suitable acquisition targets in the future. However, the overseas market is more mature than the Chinese market, and the growth space is limited. The risk of "going out" is really not small.

Secondly, Nongfu Spring also faces the problem of "succession". The company has five executive directors. Among them, the founder Zhong Shuzi currently serves as the chairperson and general manager of the company, with a shareholding of 87%. Appropriately reducing the founder’s shareholding ratio through listing can achieve the effect of optimizing the shareholding structure and reducing decision-making risks. At present, Zhong Shuzi is 66 years old and has been deeply involved in the operation of Nongfu Spring. Another executive director, Guo Zhen, deputy general manager in charge of the overall operation and production of Nongfu Spring, is also 62 years old. Zhong Shuzi, the son of Zhong Shuzi, is currently a non-executive director of the company and does not participate in daily operations. Zhong Shuzi joined the group in 2014 and is currently the general manager of Yangshengtang (Nongfu Spring Holding Company) Brand Center.

It is worth mentioning that at the same time as the listing of Nongfu Spring, another company controlled by founder Zhong Shanyuan, 603392.SH, landed on the class A share main board on April 29. The current market value is 6 billion yuan, and the daily limit has not been opened. In the Hurun wealth list in 2020, Zhong Shanyuan was listed with 14.10 billion yuan. With the listing of the above two companies, his worth is expected to rank among the top five on the rich list.

　　Recently, the General Office of the Ministry of Education issued the Notice on Further Strengthening the Sleep Management of Primary and Secondary School Students (hereinafter referred to as the Notice), further emphasizing the need to ensure adequate sleep time for students and refining relevant management measures. The "Notice" requires that students’ sleep monitoring and supervision should be strengthened, students’ sleep status should be included in the physical health monitoring and education quality evaluation and monitoring system, included in the scope of daily supervision and the supervision and evaluation of the government’s performance of educational duties, and a supervision and reporting telephone or network platform should be set up to ensure that the requirements are in place and effectively ensure students’ good sleep.

　　We should fully improve our understanding of the importance of sleep health.

　　The Notice puts forward three "important times". The first is the necessary sleep time. Primary school students should sleep for 10 hours a day, junior high school students should sleep for 9 hours and senior high school students should sleep for 8 hours. The second is the school schedule. Class starts at 8: 20 in the morning in primary schools and 8: 00 in middle schools. At the same time, it is emphasized that schools should not require students to arrive at school in advance, and necessary lunch breaks should be guaranteed if conditions permit. The third is bedtime at night. Pupils are generally not later than 21: 20, junior high school students are generally not later than 22: 00, and senior high school students are generally not later than 23: 00. At the same time, guide parents and students, make schedules for students’ work and rest, promote autonomous management, work and rest regularly, and go to bed on time. Only by controlling the school schedule and students’ bedtime at night can students’ necessary sleep time be effectively guaranteed.

　　Lv Yugang, director of the Department of Basic Education of the Ministry of Education, pointed out that schools can manage the morning classes. The more important time is bedtime at night. Some bad living habits, such as watching mobile phones, playing computers and indulging in the Internet, affect students’ bedtime. Whether you can sleep at night depends on the students’ self-management ability and the guidance, cooperation and consultation between parents and students. In this process, we should strengthen the education of students, strengthen the guidance of parents, and strive to ensure that the bedtime at night can be achieved.

　　Zhu Dongbin, deputy director of the Department of Basic Education of the Ministry of Education, said that places and schools with conditions should guarantee students the necessary lunch break. We also encourage all localities and schools to explore all kinds of good experiences and practices that help students sleep according to the actual situation and school facilities. Sleep is a big event, and we should be able to reach a consensus that we should not lose big because of small things, let alone give up the basics.

　　Jiang Fan, secretary of the Party Committee of Shanghai Jiaotong University School of Medicine, director of the Center for Diagnosis and Treatment of Children’s Sleep Disorders, and head of the Children’s Sleep Study Group of the Sleep Medicine Committee of the Chinese Medical Doctor Association, said: The majority of primary and secondary schools, teachers, parents and students should fully raise their awareness of the importance of sleep health, and enhance their understanding of the requirements of sleep time required by different age groups and healthy sleep habits. According to the Notice, the length of sleep students should get every day is consistent with the internationally recognized recommended length of sleep. This requirement is implemented on individuals, and parents also need to master individual differences. Primary school students need 9-12 hours of sleep every day, and middle school students need 8-10 hours. Teachers and parents can strengthen communication with their children, work out schedules suitable for individual students together, and at the same time, they can know whether they sleep well or not from the aspects of children’s mental state and self-feeling, and make adjustments to the schedules according to the actual situation.

　　Sacrificing sleep time for study can’t be exchanged for improving academic performance.

　　In view of the external factors affecting students’ sleep, the Notice puts forward three "interruption mechanisms", requiring homework, off-campus training and games to make way for students’ sleep.

　　The first is the "interruption" of homework, which requires primary school students to basically complete their written homework in school, and middle school students to complete most of their written homework in school. If individual students have not finished their homework by bedtime after efforts, parents should urge them to go to bed on time and not stay up late to ensure adequate sleep. Of course, teachers should conduct targeted analysis, strengthen counseling, and adjust the content and amount of homework if necessary. The second is the "interruption" of off-campus training time, which requires that the off-campus offline training end time should not be later than 20: 30, and the online live training end time should not be later than 21: 00. Homework should not be arranged in any form such as pre-class preparation, after-class consolidation, homework practice, and WeChat group punching. The third is the "interruption" of the game, which requires local education departments to strengthen supervision with relevant departments in accordance with their management authority to ensure that no game services are provided to minors from 22: 00 to 8: 00 the next day.

　　Lv Yugang said that schools should have a sound homework management mechanism, and all subject groups should co-ordinate homework, so as to grasp a reasonable amount of homework and improve the quality of homework. Students should not be allowed to finish their homework during recess when they should go out for activities and jump around the playground, or during the lunch break. Schools and teachers should strengthen the guidance for students to complete their homework, especially to help students with learning difficulties, and increase the intensity of counseling and answering questions so that students can complete their homework within the specified time.

　　Lu Haifeng, director of the Education and Sports Bureau of Qidong City, Jiangsu Province, reminded schools to avoid the thinking mode of split thinking and binary opposition, and make efforts to properly handle several groups of relationships. The first is the relationship between "sleeping less" and "sleeping late" and "getting up early". According to the requirements of the Notice, schools should reasonably determine the schedule of work and rest, enhance the soft power in the publicity of work and rest, and enhance the hard power in the implementation of work and rest, and do not artificially require students to arrive at school in advance, and do not artificially occupy students’ school time. At the same time, they should be flexible and flexible in strictly implementing work and rest, for example, properly resettle individual students who arrive at school in advance due to special family circumstances; The second is the relationship between "less sleep" and "more homework" and "difficult homework". Schools should make great efforts in classroom research and win the light burden of schoolwork with the high efficiency of classroom; Pay attention to homework management and win the light load of homework with the high quality of design; The third is the relationship between "sleeping well" and "sleeping well" and "growing well". Schools should face students face to face, educate students to understand the importance of adequate sleep and develop good sleep habits. Heart-to-heart with parents to guide parents to be the guarantors of their children’s adequate sleep; Join hands with the society and participate in the governance of off-campus training institutions as much as possible to reduce the academic burden of students.

　　At the same time, Jiang Fan said that parents should take appropriate restrictions on children’s use of electronic products, and at the same time, they should set an example and consciously maintain a good work and rest, so that children can clearly understand the importance of sleep and develop a good habit of maintaining regular work and rest independently. Their team research shows that sacrificing sleep time for study can not bring about improvement in academic performance, but will cause extensive damage to executive function and affect the academic performance of children and adolescents.
