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.

　　What is "internet plus"? How does it affect our life step by step? Simply put, "internet plus" is the combination of traditional industries and the Internet. Relying on advanced Internet technology, Internet platform and Internet industry chain, various traditional industries have deeply integrated the Internet with traditional industries and created new economic forms. Worldwide, internet plus has set off an upsurge of upgrading traditional industries.

　　In this upsurge, both large and medium-sized enterprises and small and micro enterprises are gearing up for transformation. When all enterprises are seeking transformation, relying on their unique resources, platforms and user advantages, large enterprises can often quickly connect with the Internet in a very short time. For example, Intime Department Store teamed up with Alibaba to build an online payment platform; Midea and Xiaomi married and launched intelligent induction air conditioning.

　　Faced with the transformation of large and medium-sized enterprises, some small and micro enterprises began to become anxious. The transformation of large enterprises is either a platform, a system or an industrial chain. They have rich resources, huge user groups and detailed data … which small and micro enterprises do not have. Without a platform, data, users, resources and internet marketing technology, how can small and micro enterprises transform?

　　Fortunately, the opportunities that the Internet brings to everyone are equal. Make good use of Internet technology to make the Internet the source of its own power, and every enterprise in the development of the Internet industry has the opportunity to achieve itself on the Internet.

　　This book is different from the previous books about "internet plus". There is no lofty theory or unreachable routine. It is all about concrete, operable and ready-to-use strategies for internet plus’s transformation.

　　In this book, I summed up my many years of working experience and practical experience in guiding small and medium-sized enterprises all over the country, and discussed in detail how small and micro enterprises can achieve themselves with "internet plus", and how small and micro enterprises and entrepreneurial enterprises can survive in the cracks when all walks of life are carrying out "internet plus".

　　Under the current situation, there are many entrepreneurial enterprises at home and abroad, with a large base. Faced with the opportunities brought about by the vigorous development of the Internet, many young people want to join in and break out of their own world.

　　Then, in the Internet age, young people want to start a business and small and micro enterprises want to develop. How should they do their own Internet marketing? In fact, as long as we make good use of some artifacts on the Internet, both individual entrepreneurs and small and micro enterprises can achieve good development.

　　Liu Pengfei, a young man born in 1980s from a poor mountainous area, discovered a business opportunity by an unexpected opportunity-selling Kongming lanterns. Kongming Lantern has a simple structure and almost no technical content. Liu Pengfei can do it himself.

　　After getting the salary of 1,400 yuan in the first month, Liu Pengfei fired his boss "Squid", and used 400 yuan to buy more than 100 Kongming lanterns to start e-commerce.

　　Through online inquiry, Liu Pengfei found that no one sold Kongming Lantern on Alibaba and China-made platforms, but there were merchants abroad searching for Kongming Lantern through Google search engine. Liu Pengfei thought it was an opportunity and began to make great efforts to produce Kongming lanterns. At this stage, Liu Pengfei found the first bucket of gold in his life.

　　In 2008, the number of manufacturers of Kongming lanterns in China increased sharply, and the competition was fierce. The major manufacturers started a price war. Liu Pengfei realized that Kongming Lantern must be promoted to the international market. As a result, Liu Pengfei introduced the "Flying China Lantern" to the world through Alibaba’s export link and Google search engine.

　　In August, 2008, Liu Pengfei accepted the order of 1.5 million Kongming lanterns from the third largest German retailer. He expanded the scale of the enterprise, which made the enterprise’s benefits grow by leaps and bounds again and again, and realized the soaring 400 yuan to 70 million yuan.

　　It doesn’t matter if you don’t have a platform, just use the existing platform. Without its own platform, Liu Pengfei, a young man born in 1980s, can still succeed in starting a business, which gives us profound enlightenment. In the Internet age, as long as you are good at using all available Internet resources around you, you can also succeed in starting a business.

　　What are the most available resources around us for small and micro enterprises and some individual entrepreneurs? Mobile apps such as WeChat and Weibo are indispensable in people’s daily life.

　　The pace of modern life is accelerating, and mobile phones have become an important part of people’s daily life. As long as we can make a fuss about customers’ mobile phones, we can attract customers to the maximum extent and complete the perfect connection between enterprises and the Internet.

　　How to make good use of existing resources to do a good job in internet plus marketing? We must master four modes and four stages of fan marketing.

　　What are the four marketing models in internet plus? It is a fan mode, a free mode, a mobile Internet mode and a self-media mode. None of these four modes requires enterprises to invest too much manpower and material resources, but the effect is obvious. For example, the sliding screen unlocking software means that by cutting into the user’s mobile phone, the mobile phone user can download other APP applications through sliding screen unlocking, and can get corresponding benefits, which greatly mobilizes the user’s enthusiasm for participation.

　　What are the four stages of fan marketing in internet plus? We often say "no fans, no marketing". In the Internet age, if you want to keep your fans, you need to do these four stages: First, get your circle of friends; Second, learn to run your own WeChat official account; Third, you must have your own APP；; Fourth, establish your own ecological circle.

　　Through gradual deepening and upgrading step by step, every start-up enterprise or individual can master the essence of internet plus, make internet plus’s theory and routines work for me, and do well in the Internet field.

Biden, who has rich experience, also got the president’s name wrong during the Great Depression.

　　Beijing, Sept. 24 (Xinhua)-In the current US general election, from the primary election of the two major parties to the current campaign, it seems that it has become a common occurrence for candidates or candidates to make slips of the tongue, say the wrong words or quote wrong data. Biden, the Democratic vice presidential candidate, made a mistake in the name of the American president in the Great Depression when he was interviewed by a TV station recently and expressed his views on the recent financial tsunami.

　　According to Sing Tao Global Network, Biden said in an interview with the CBS evening news program that the leaders of today’s generation should learn from history books and learn from the late American President Roosevelt how to respond to the financial crisis.

　　Biden said: "Do you know? When the stock market crashed, Roosevelt went on TV, not only complaining about how greedy others were. He said,’ Look! This is happening now!’ "

　　However, looking up the history books, when the American stock market plunged in October 1929, which opened the curtain for the Great Depression, the president was not Roosevelt who belonged to the Democratic Party, but Hoover who belonged to the Republican Party. Roosevelt was elected to the White House three years later, that is, in the election year of 1932, and Hoover failed in his re-election. During his campaign, Roosevelt promised to take new actions to lead the country out of economic difficulties.

　　It seems that Democrats often want to deliberately remind the public and voters that when the stock market crash triggered the Great Depression in 1929, the Republican Party was in charge. In the election year of 2004, the then Democratic candidate Kerry also repeatedly used Hoover as a topic, saying that he was the president who witnessed the shrinking employment position during his last term of office, followed by Bush.

　　Commenting on the recent stock market crash, Biden said that leaders of today’s generation should explain to the public the current economic crisis and how to solve it. He pointed out: "As a leader, what you should do is to slowly restore the public’s confidence, show that they know what happened, and communicate with the public to explain how to solve the problem."

　　This is not the first time that this presidential candidate or primary candidate has said something wrong. I remember that during the Democratic primary election, Hillary Clinton, a female senator from New York, once boasted and recalled the scene of bullets at the airport when she arrived in Bosnia by plane, but the reporter looked at the news clips and there was no such thing at all.

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.
