Cross-border e-commerce is an opportunity. Thanks to the rapid rise of Internet business, more and more people have recognized online shopping. The rules of online shopping platform have been greatly improved to standardize the online transaction process. Governments have also seen the future economic development direction and encouraged enterprises to invest resources to develop Internet infrastructure and logistics facilities. In short, cross-border e-commerce has become an indispensable part of global business.

1. What impact does cross-border e-commerce have on global business?

Cross-border e-commerce can become the representative of Internet business, which has had an unimaginable influence on global trade for a long time. Just as there were basically no imported products in China before, few people were able to use imported products, but the trend of economic globalization began in the 1980s, and foreign capital and products entered the markets of various countries at will, enriching the lives of local people. However, the traditional trade route was difficult, and because of the high tariffs, It is also necessary to pay value-added tax and consumption tax. Many imported products have become luxury goods overnight, but they have changed hands from cheap products to luxury goods through multiple companies. This trade method is only suitable for brand channel providers, and enterprises that do not need special channels can completely benefit consumers, so that products can truly become the welfare of consumers.

The emergence of the Internet in the 1990s has enabled business to find a new platform, and business can be done all over the world quickly.

What impact does cross-border e-commerce have on global business?

First, cross-border e-commerce has turned "global selling, global buying" from a myth into a reality. Good business actually means that the more convenient it is, the more development potential it has. Cross-border e-commerce can make it easy for people living in Britain to buy goods made in the United States on the other side of the ocean without leaving Britain, and it can make it easy for people living in the United States to buy goods made in China without leaving the United States. Besides global buying, they can also sell French-made perfumes and cosmetics to the United States through cross-border e-commerce. You can also sell clothes made in China to the UK through cross-border e-commerce, and cross-border e-commerce uses the Internet to efficiently sell goods from manufacturing countries to demanding countries, thus realizing long-distance and high-efficiency trading.

Second, the rise of cross-border e-commerce has given birth to a number of emerging cross-border industries. In particular, the global logistics industry has developed rapidly. Cross-border e-commerce does not exist independently. It needs industrial support, such as delivering goods to foreign customers and passing through international logistics. The fastest way of international logistics is air transportation, which requires customs declaration in the destination country and finally delivery to customers. Logistics plays an important role in cross-border e-commerce transactions, as well as cross-border payment. It can ensure the safety of foreign customers’ funds and sellers’ funds, as well as intellectual property certification services. Trademark registration and VAT tax number registration are indispensable for cross-border e-commerce business. Certification must be done before platform stores operate to protect their brands from infringement. These emerging cross-border industries have developed very rapidly, thus continuing to promote the development of cross-border e-commerce.

Third, the rapid growth of cross-border e-commerce has brought tax revenue to governments all over the world, and also solved a large number of jobs, especially young people are very fond of Internet careers. In the past five years, the global cross-border e-commerce transaction volume has shown double-digit growth, especially some manufacturing countries have made great profits during the development period of cross-border e-commerce. Some mainstream cross-border e-commerce platforms such as Amazon, eBay, wish and AliExpress have great market environment potential, and manufactured products in underdeveloped areas can use these cross-border e-commerce platforms to obtain high profit returns.

2. What are the global policies for cross-border e-commerce?

The emergence of cross-border e-commerce is not only the result of market choice, but also the result of governments’ efforts to encourage the development of cross-border e-commerce. Without the platform technology of cross-border e-commerce, there would be no well-being of people around the world. Let’s take a look at how some mainstream market countries in the world develop cross-border e-commerce. Xiaobian has classified and summarized:

(1) On May 16, 2013, the United States passed the Market Fairness Act, which levied sales tax on cross-border e-commerce buyers. No tax was levied on goods below $200, and States levied sales tax on online retailers with annual sales of more than $1 million, and exempted tariffs on online transactions of intangible goods. These tax policies are encouraging local enterprises to actively develop cross-border e-commerce.

(2) Britain’s import declaration policy is loose. In Britain, which is in the predicament of Brexit, the British government encourages goods from other countries to transit to Britain. According to the Daily Mail survey, 80% of British netizens often shop online. The British government attaches great importance to the development of its own e-commerce market.

(3) In 1998, the European Union began to levy value-added tax on e-commerce and business tax on suppliers who provide online sales and services. In 1999, the European Commission announced the tax standards for online transactions, and no new tax or additional tax was levied. The European Union has formulated a tax system since the rise of e-commerce, without increasing the tax burden on online retailers.

(4) In 1998, Japan announced the basic guidelines for e-commerce activities, emphasizing the principles of fairness, tax neutrality and tax simplification in taxation to avoid double taxation and tax evasion.

(5) On March 7, 2015, the State Council agreed to set up China (Hangzhou) cross-border electronic commerce Comprehensive Experimental Zone, and on January 6, 2016, the State Council set up a number of cross-border electronic commerce Comprehensive Experimental Zones in 12 cities including Ningbo, Tianjin, Shanghai, Chongqing, Hefei, Zhengzhou, Guangzhou, Chengdu, Dalian, Qingdao, Shenzhen and Suzhou. On August 7, 2018, the State Council established cross-border electronic commerce Comprehensive in 22 cities including Beijing, Hohhot, Shenyang, Changchun, Harbin, Nanjing, Nanchang, Wuhan, Changsha, Nanning, Haikou, Guiyang, Kunming, Xi ‘an, Lanzhou, Xiamen, Tangshan, Wuxi, Weihai, Zhuhai, Dongguan and Yiwu. Up to now, 35 cross-border electronic commerce pilot zones have been set up in China, which is enough to show the support of the China government for cross-border e-commerce.

Third, what magical commercial power does Amazon have to achieve the largest platform for cross-border e-commerce

The development of Amazon is a shortened history of e-commerce in the world, catching up with the emerging Internet. Apart from the promotion of the Internet tide, there are also Amazon’s own reasons. Let’s talk about what magical business power Amazon has to achieve the largest platform for cross-border e-commerce, such as:

(1) The founder of Amazon has a unique vision and sees opportunities for e-commerce to surpass physical business in the future. Jeff Bezos, the founder of Amazon, just started his business and chose to use the Internet to sell books. Because books are a standard commodity, they are very suitable for online sales, so books have become a golden key to open the online retail market. At that time, Bezos saw that the online book market was far greater than the physical book market, and dared to make a bet to develop the online book retail market.

(2) Amazon saw the value of the Internet virtual community earlier, allowing sellers and buyers to communicate on the e-commerce platform, so that they could evaluate the goods. Later, the Prime membership system evolved, which greatly protected the rights and interests of online shopping users and spread the reputation of Amazon.

(3) Amazon saw the potential of cloud computing and the essence of Internet business during the period of platform growth. The platform must rely on powerful cloud service capabilities and ensure the security of every transaction. Amazon’s Excellence in technology has enabled Amazon to become the world’s largest e-commerce platform. (Source: Everyday Cross-border)

Today is the "International Day for the Blind". Do you think that blind people can’t see in broad daylight and how can they see in their dreams at night? It’s not that simple.

In fact, there are two kinds of blind people: congenital blind and acquired blind.

Image source: pexels

The first type: the acquired blind, who originally had perfect vision and had seen the world, can still see things in their dreams, although they became blind later.

The second kind: congenital blindness. People usually think that since they have never seen anything since they were born, they certainly have no vision in their dreams.

But in fact, is this really the case?

An experiment to depict dreams

In 2003, a Portuguese scientist claimed that people who were born blind could see images in their dreams. They designed such a set of experiments:

A total of 19 participants, 10 were born blind and 9 were visually sound.

The experiment requires that participants sleep normally at home.

However, there will be four alarm clocks to wake them up at night. After waking up, the participants described their dreams to the tape recorder and then went back to sleep.

The next morning, the sighted people asked to be blindfolded and draw their dreams on paper with other participants.

Here are the results. Can you identify which one was painted by a blind person?

The first hand-drawn dream map

Image source: reference [2]

The second hand-painted dream map

Image source: reference [2]

The answer is as follows ↓

The first picture is a dream recorded for the blind.

Therefore, Portuguese scientists have come to the conclusion that the description of dreams by the congenital blind and the visually sound is indistinguishable.

The way blind people see the world is not just their eyes.

Does this mean that the congenital blind have vision in their dreams? Not necessarily.

In fact, not only vision can produce images, but also the senses of touch and hearing.

Let’s talk about touch first. In the story of the blind touching the elephant, the blind touching the leg will draw a tree, the blind touching the body will draw a wall, and the blind touching the tail will draw a rope. If you touch the elephant’s whole body, the blind can draw a complete elephant. Just by touching, the brain can also form images and draw them. Scientists have studied congenital blind people and found that their tactile signals will flow into the visual cortex in the brain, thus creating images.

Image source: pexels

There are also some reports that the congenital blind can produce images by hearing. Like bats, they have the ability of echolocation, and they can hear the general structure of the house only by the echo of high heels stepping on the ground.

Some scientists also believe that blind people can see things in their dreams, which is actually a psychological experience similar to echolocation.

A study on blind people found that:

People who are born blind have no vision, nor do they dream;

People who are blind before the age of 5 will also lose their visual impression;

People who are blind after the age of 7 will always leave visual cognition;

In short, the scientific community still has no clear answer to the previous experimental results. But describing a dream is not necessarily because the blind man opened his eyes in the dream, but also because of his sense of touch and hearing.

Finally, let’s look at a picture of a dream painted by a congenital blind person.

Congenital blind people describe dreams:

The sun, sailboats, seabirds, clouds, coconut trees,

There are two happy people

Image source: reference [2]

Blind people have no vision, but this does not prevent them from making an accurate and poetic description of the world. Touch, smell and hearing can also become their "new eyes" to see the world.

After several months of plague, people can’t catch up with the speed of new bodies, and Constantinople, which was originally prosperous, has almost become an empty city. Many people go crazy before they die, run to the street and dance around, and then die suddenly and fall down. The corpse truck covered the corpse with flowers to cover its odor, and the ashes of burning corpse floated in the air. On July 5, the official micro-signal of Bayannaoer Health and Health Commission issued a notice, saying that the suspected plague cases reported by Urad Zhongqi Hospital on the 4th were diagnosed as bubonic plague cases by the expert group. On July 6, the patient’s condition was stable and life-threatening, and he is currently being treated in isolation in the infectious disease ward. Follow-up investigation of close contacts around it is still in progress. Beijing CDC issued an important reminder to stay away from the grassland, not to eat wild animals, and not to camp in the grassland for the night.

Characteristics and symptoms of plague

Plague is an ancient infectious disease, which is caused by Yersinia pestis. It is a special zoonosis that rodents and fleas transmit Yersinia pestis to humans and animals. It is a Class A infectious disease. The incubation period of plague is generally 1 to 6 days, and individual cases can reach 8 to 9 days. According to different modes of infection, the common plague can be manifested as bubonic plague, pneumonic plague and septicemia plague, and the patients in Bayannaoer this time are bubonic plague. The bubonic plague suddenly developed chills, high fever, headache, fatigue, general aches, nausea, vomiting, restlessness, skin ecchymosis and bleeding. The lymph nodes in the drainage area of rat flea bite were swollen and swollen, which developed rapidly and reached the peak on the 2 nd to 4 th day. Inguinal lymph nodes are most frequently involved, followed by axillary, cervical and submandibular lymph nodes. The route of transmission of plague is a natural focus disease, and the host animals carrying plague bacteria are mainly rodents such as rats and marmots. 1. The transmission of rat flea bites is the main route of transmission, which can spread pathogens (Yersinia pestis) from animals to people, forming a transmission mode of "rodents → fleas → people". 2. The respiratory secretions of patients with respiratory infection contain a large number of Yersinia pestis, which can spread from person to person through respiratory droplets and cause human plague pandemic. 3. Transmission through skin contact. The damaged skin mucosa of healthy people can be infected when it comes into contact with the pus and sputum of patients or the skin and blood of diseased rodents.

Bayannaoer City started the Class III early warning period of plague prevention and control on July 5, and the early warning period will last until the end of 2020. One case, as for letting the whole city "make a mountain out of a molehill" into an alarm state? This is no exaggeration at all. After all, living in modern times, we have never experienced the three "baptisms" of plague in human history, and it is understandable not to understand its horror. These three plagues were called "Justinian Plague", "Black Death" and "Yunnan Plague" by later generations. History cannot be erased, because it really affects human beings too much-according to the statistics and estimates of historians, plague killed at least 180 million people.

Since 542: natural disasters, divine punishment, and nothing can be done.

Patients always think that the end of the world is coming, and self-harm and self-abuse often occur.

In an era when medicine is still completely underdeveloped and even relies on shamans, witch doctors and alchemy to cure diseases, infectious diseases are no different from natural disasters. In 542 AD, the plague broke out in Africa, and then spread all over Europe and West Asia along the Mediterranean trade route. At that time, the scene was like death arrival. The doctor didn’t know what disease it was, where it came from, let alone how to treat it. All people could do was pray.

The symptoms of this great plague mainly include the following: first, patients are mostly manifested as unconsciousness and listlessness. After being affected by the plague, compared with normal people, patients always feel an illusory scene in front of them, always think that the end of the world is coming, and often suffer from self-harm and self-abuse due to this influence. Secondly, the lymph in the patient’s thigh is swollen and presents the appearance of decay. These superficial people tend to have thin thighs, persistent head fever and diarrhea. Third: There are many erythema on the patient’s body. At the beginning of the plague, only some parts of the body showed signs of erythema. After a period of time, the place where erythema had previously appeared began to fester, and finally the patient should die of physical ulceration and mental disorder.

As for the numerous unclaimed dead bodies caused by the plague, the emperor buried them on the spot. Because the number of dead people was too large, it was a very complicated job to bury them. In order to solve the stench of the dead bodies in the city, Justinian also ordered people to dig dozens of huge deep pits in the galata area of Golden Horn Bay to bury the dead bodies. In these pits, in order to keep enough space as much as possible, all the bodies were stacked together in a certain direction and order. It is said that each pit can bury about 70,000 bodies. Although this way of burying corpses may not be an effective measure to control the plague at present, it did play a certain role objectively under the conditions at that time.

Even the most powerful Eastern Roman Empire at that time lost 14 million people and even the emperor was bedridden. According to historians’ estimates, about 100 million people died in this disaster.

Beginning in 1348: a black nightmare that lasted for more than 70 years.

The plague is pervasive, has no national boundaries, and does not distinguish between races. No country can be exempted.

There is a famous "Church of Human Bone" in Kutnahola, a small town about 70 kilometers east of Prague. The decorations such as candlesticks and chandeliers are all patched together from different parts of human bones, and the scalp of the audience is numb. In Europe, it is not surprising that similar "human bone churches" exist in many cities. Most of these human bones came from the mid-14th century-the Black Death swept across Europe, killing about 25 million people (nearly half of the total population of Europe at that time) in a few years, and even killing people and leaving bones everywhere.

In 1346, a plague broke out in Kafa, a commercial colony of the Republic of Genoa on the Black Sea. Normal people fell down one by one, and the death toll soon exceeded that of the living. The government used wooden poles to push the bodies with nowhere to be buried into the sea nearby, and the port was abandoned. Infected people grow large lumps on their faces, necks, armpits and groins, and their skin appears dark spots. Most of them will die within 48 hours of infection. At that time, people gave this plague an image name-The Black Death.

A Genoese went to Piacenza, northern Italy, to visit his relatives and was forbidden to enter the city. At that time, it was raining, and he cried and begged outside the city gate until dark. His relatives really couldn’t bear to secretly open the city gate and take him home for the night. The next morning, the relative went to the streets … A few days later, there was no living person in Piacenza. A few weeks later, the Black Death marched into Milan, Turin, Verona and Florence … The whole of Italy suffered, and Florence was the worst, with 95,000 people in the city dying 55,000 people. "Florence suddenly became a hell on earth: pedestrians walked in the street and suddenly fell to the ground and died; People who stay at home die alone, and no one knows until the body odor is smelled; Every day, a large number of bodies are transported outside the city every hour; Cows wander around the streets of the city, but no one can be seen … "Boccaccio, an Italian writer who is known as the three outstanding figures in medieval literature, experienced the Black Death, which he wrote in his collection of novels decameron. In 1348, the plague soldiers divided into many ways and conquered the whole European continent. Except for the British Isles and Scandinavia, no country was spared. England also failed to survive the spring of 1349. The Black Death suddenly entered the Channel Islands from Calais, and then marched into Great Britain. By May, there were only 30,000 residents left in London. British merchant ships brought the virus to Scandinavia, and even Greenland suffered. People turned pale when they heard the Black Death, and the dark medieval Europe fell into a dark moment. The plague is pervasive, has no national boundaries, regardless of race,No country can be exempted. 　　

Compared with the first pandemic, medicine in this period not only failed to make progress, but even the sanitary conditions declined because of the war. In the 15th and 16th centuries, the plague tortured human beings for 300 years. The average life span of the population in the epidemic area was only 20 years old, which was not as good as that of primitive people. The European continent lost nearly half of its population.

"The usual source of infection is the black rat, sometimes called the old English rat. This animal is closely related to people, and it is a beautiful little guy with black fur. Unlike the brown mouse, it likes to live in houses and boats, rather than in farms and sewers. Being close to people makes it easy for fleas to jump from mice to people, which will also spread plague. This disease, whether it is for rats or people, has a high mortality rate once it is infected. " Frederick F Cartwright and Michael Biddis described it in "Disease Changed History". "Many people with carbuncle and swollen glands have survived, but no one lives vomited blood." This description comes from Karl Lechner’s book The Great German Plague: 1348-1351.　

"People who vomited blood died soon. Some people were healthy, but suddenly they vomited blood, and then they died. There is no medicine to cure. " The text is from Piacenza and Parma, written by Dominican friar John Descornes Zano. According to the records of Byzantine emperor John Kantakuzen, there is no cure for this disease. Neither a regular life nor a strong body can resist this disease. Whether you are strong or weak, you will be knocked down by the disease. A well-fed aristocrat is as hard to avoid death as a poor man with nothing. There are no other types of diseases this year, and all diseases are like this epidemic. Medicine is powerless in the face of the epidemic. The process of illness varies from patient to patient. Some patients die suddenly, some patients stay sick for one day, and others only last for one hour. Those whose illness can last for two or three days first have a high fever. Then the disease invaded the brain, and the patient lost his language ability, and he didn’t know anything about what was happening around him. He looked like a deep sleep. If the patient can wake up and want to talk, his tongue can’t move and he can only pronounce a few vague syllables because the patient’s nerves are paralyzed. Here we go. The patient suddenly died. Other patients don’t have symptoms in the head, but their lungs and respiratory organs become inflamed quickly, and they have severe chest pain and vomit blood. The patient’s exhaled breath became foul-smelling, and his throat and tongue became black and congested with high fever. 　 　 　 　　

Most people infected with this disease are doomed to death. People don’t know what to do except pray and run away. In extreme fear, people came up with various methods, such as smoking the room, taking a bath with urine, burning lymph nodes and putting dried toads on them … However, none of them worked. The government has introduced many measures, including mandatory reporting, isolating patients, burning the articles of the people who died of the Black Death, and issuing relevant laws prohibiting doctors from leaving infected areas. Plague doctors (who specialize in treating plague patients) can only wear "strange clothes" in order to protect themselves from being infected by "poisonous gas" with viruses. This kind of protective clothing is usually a jumpsuit consisting of a large piece of leather or batik canvas, a large piece of crystal glass and a long beak. The bird’s beak is stuffed with spices (such as camphor, mint, clove and myrrh), dried flowers (such as roses and carnations) and even a sponge stained with vinegar. Because the protective clothing can’t defend against the poisonous gas carrying the virus, the plague doctor can only hope that these articles with strong smell can dilute the poisonous gas. 　

Plague doctors usually carry a cane. According to the scholar G. L. Townsend, this kind of walking stick has a wide range of uses, such as: giving instructions to "ventilate" the patient’s dark house where toads and spiders are crawling everywhere, letting the patient "suck some bottled air", taking a bath with urine, eating laxatives or stimulants; Measure the patient’s pulse, take off the patient’s clothes, and push away patients who are too close to themselves. Plague doctors will sign a contract with the city government, which stipulates that they must wear this protective clothing. If this "humanoid bird" appears at the door, it means that death is not far away.

Plague doctors’ headgear in 17th century Germany/Austria. Even if there is a plague doctor in the German History Museum in Berlin, too many people can be infected and die too quickly. The cemetery was no longer enough, so people dug ditches and lined up hundreds of bodies like cargo on a ship. Sprinkle a little soil in the middle of each layer of corpses until the ditch is filled. 　 　

"medical team" Another Italian writer at that time commented: "A father will avoid his seriously ill son, a brother will avoid his sick brother, and a wife will stay away from her sick husband. Healthy people will be very careful to avoid patients. Priests and doctors are even afraid to go near patients. Everyone ran away when they saw the body. " 　 　

In the end, the second epidemic of plague lasted for more than 70 years, spreading to Europe, Asia and Africa, taking a quarter of the population of Europe. It once led to the collapse of European society and entered a state of chaos and disorder. The "Black Death" caused about 75 million deaths worldwide, including more than 25 million deaths in Europe. If we want to say the end of the second plague outbreak in the true sense, it will have to wait until the seventeenth century or even 1800. 　 　 　

Beginning in 1855: The culprit finally appeared. 　

Control traffic, isolate epidemic areas, cremate bodies, establish hospitals for treatment …

There are different opinions about the origin of this epidemic, but the mainstream thinks it was in Yunnan, China in 1855. Compared with the previous two pandemics, the third plague pandemic has obvious differences: firstly, its spreading speed is faster and its spreading area is far ahead of the previous two times, and it has spread to more than 60 countries in Asia, Europe, America and Africa in several decades; Secondly, although the death toll has reached an astonishing 12 million, compared with the previous two times and the vast scope, the death rate has been significantly reduced. 　 　 　　

The Man with the Plague Head Cover on Bo Veglia Island (1899) The plague pandemic didn’t end until 1959, and its historical influence dropped obviously compared with the two world wars. 　　

The biggest impact of this plague pandemic was to find the real cause of plague-Yersinia pestis: in 1894, the famous French biologist Yersin successfully discovered the pathogen of plague, and in the following year, he developed the anti-plague serum. Since then, human beings have scientific methods to prevent and treat plague.

It is worth mentioning that from 1910 to 1911, there was another plague that spread from Russia to the three northeastern provinces. This plague caused more than 60,000 deaths, and at one time there was a tragic situation of "the whole village lost its family and died of serious illness". In order to cope with the spread of plague in the three northeastern provinces, the Qing government immediately set up the "Jingshi Epidemic Prevention Bureau" and set up its inspection office in Shanhaiguan to conduct quarantine in Haikou. In addition, the Qing government also established the "World Plague Research Institute" in Fengtian (today’s Shenyang) at that time, and in 1911, it established the "Plague Research Institute" in Harbin. In these two institutions, Dr. Lien Teh Wu, a famous medical scientist, is the president and director of the research institute.

Lien Teh Wu took effective prevention and control measures such as controlling traffic, isolating epidemic areas, cremating corpses, and establishing hospitals, which made the plague that shocked China and foreign countries under control in less than four months. In recognition of Dr. Lien Teh Wu’s achievements in fighting the plague pandemic, the Qing government also awarded him the rank of Army Blue Ridge and a medical scholar, even known as the "Plague Fighter".

Now, the plague is very rare, but it has not completely disappeared, because it will still spread among rats and mice, and will spread to people whenever possible. In 1980s, plague was reported every year in Africa, Asia and South America. The plague that broke out in India in 1996 also became a major news in the world. At present, about 1000 to 2000 people are infected with plague every year. Even in the United States, on average, more than 10 people are infected with plague from wild rodents every year, and 1/7 patients die. After the founding of New China, the Chinese government attached great importance to the prevention and control of plague, and the number of cases dropped significantly. By the 1980s, an average of about 20 cases were reported every year. In the 1990s, the epidemic situation of plague in southern China rose briefly, and only sporadic cases were reported every year since 2010, mainly in some provinces in northwest China. Not long ago, in November 2019, two cases of pneumonic plague were also confirmed in Beijing. Everything tells us that the plague has never left.

How can the public do personal protection?

Experts remind the general public to do personal protection in strict accordance with the requirements of "three noes and three reports" for plague prevention and control, and to improve their awareness and ability of self-protection. 　　　

1. "Three noes": Do not hunt animals with epidemic focus, do not strip animals with epidemic focus, and do not bring animals with epidemic focus and their products out of the epidemic area without permission. 　　　

2. "Three Reports": report the discovery of sick (dead) marmots and other animals, report the discovery of suspected plague patients, and report the discovery of unexplained patients with high fever and sudden death. 3, should maintain good personal hygiene habits, try to avoid going to crowded places, go to medical institutions or personal symptoms such as fever, cough should wear a mask in time. 　　　

4. If you suspect that you have had contact with the case, you can take the initiative to report to the local disease control department and get professional guidance. Once you have symptoms such as fever, cough, lymph node pain, hemoptysis or bleeding, you should seek medical advice in time.　

5. When traveling, minimize contact with wild animals, don’t tease marmots with unknown health, prevent flea bites, avoid being bitten by fleas by using repellent, reduce body exposure, and don’t hunt and eat wild animals without permission.

Plague will constantly change its face and always coexist with the process of human development. Although plague is not an incurable disease and easy to control, the shadow left in people’s hearts by historical tragedies is hard to eliminate, and it is still regarded as the most horrible disease by many people.

Recently, Apple officially released the much-anticipated M4 chip, which has achieved a leap in performance.It surpasses its predecessors M3 and M2 in an all-round way, and at the same time, it maintains significant performance advantages for M3 Pro and Snapdragon X Elite.

M4 chip can achieve such a huge leap in performance, not only because Apple adopted TSMC’s second-generation 3nm process, but more importantly, it adopted a brand-new ARMv9 architecture.

The introduction of this architecture enables M4 to run complex workloads more effectively, which brings higher single-core and multi-core performance gains.

According to Geekbench 6 benchmark test results, the single-core and multi-core performance of M4 chip has reached a new high. The achievement of this achievement,It not only benefits from the frequency increase of M4 chip and the increase of core number, but also benefits from the introduction of ARMv9 architecture and the support of SME (Extensible Matrix Extension).

SME technology is an important feature of ARMv9 architecture, which can help the processor to handle complex data operations and matrix calculations more efficiently. In the test of Geekbench 6, with the support of SME technology, M4 chip has made significant improvement in both single-core and multi-core performance.

Compared with M2 chip, M4 improves the single-core performance by about 48%, and the multi-core performance by about 52%. This performance improvement is large enough to make M4 stand out in the current mobile processor market.

It is worth noting that although Apple didn’t mention that M4 adopted the ARMv9 architecture at the press conference, this fact has been widely recognized by the industry. The introduction of ARMv9 architecture not only improves the performance, but also brings higher security and energy efficiency ratio.

At the same time, there are rumors that the upcoming A18 Pro will also adopt the ARMv9 architecture and support SME technology.This will make A18 Pro comparable to M4 in performance and become a strong competitor of Apple’s new generation flagship processor.

Although more details about M4 chip have not been announced yet, its outstanding performance has attracted wide attention in the industry.

We look forward to seeing more reports on the application and performance of M4 chips in the future, and we also expect Apple to continue to introduce more high-performance and low-power processor products, which will bring users a better experience.

　　　 [Original Truck House] With the increasingly fierce competition in the domestic industry, various car companies have successively launched their own flagship brands in recent years. As a member of the heavy truck industry, I finally can’t make more tricks in the cab of Isuzu. So it came into being.

　　　 In fact, Ou Man GTL imitated it, and everyone knows this. We don’t have to judge whether it is good or not too much. After all, domestic car companies basically do this. As users, we pay more attention to the effect of use, and expect Ou Man GTL to give us a perfect answer.

　　　 In this article, we will show Ou Man GTL to you in more graphic ways. Please pay attention to other contents of Truck House about Ou Man GTL.

●　 The meaning of GTL in Ou Man

　　　 The three letters of GTL contain many meanings, such as "Global Technology Leader" (that is, world technology leader); It can also be interpreted as "Green Transport Landmark" (that is, a milestone of green transport); It can also be understood as "Gas To Liquid" (that is, natural gas synthetic oil, also known as "green dye"), but these explanations are not completely correct. In the special issue of the Mid-year Business Meeting in Ou Man, the product positioning and brand meaning of GTL were introduced in detail.

Ou Man GTL Product Positioning and Brand Meaning

●　 Ou Man GTL Appearance: Inheriting Ou Man Family Face.

　　　 As early as 2003, Ou Man began to design a new generation of cab. After seven years, Foton Motor made its debut in the GTL of Ou Man at the 2010 Beijing Auto Show. From the renderings to today’s production cars, it has made a qualitative leap. At last year’s annual meeting in Ou Man, we learned that Ou Man GTL cab can be divided into two types: flat floor cab and stepped floor cab. In addition, there is a single-row, flat-topped daytime cab. We only introduce the Ou Man GTL of the stepped floor cab here.

　　　 1. The air intake grille is upgraded without losing the family blood.

　　　 The air intake grille follows the style of Ou Man family, strengthens the brand characteristics, and is very harmonious as a whole, tough and delicate.

　　　 2. The new LOGO is more recognizable.

　　　 Ou Man GTL launched the brand-new LOGO of Foton Motor. From the appearance, the new LOGO is more distinctive and the recognition from a long distance has been improved a lot.

　　　 3. Bumper design is not well thought out

　　　 The drag hook is hidden behind the license plate frame, and the license plate can be turned down when in use; Only the lower pedal on the front bumper can stand people, and it has also been treated as anti-skid, while the upper pedal has not been treated at all. This makes it difficult to wipe the glass in daily driving.

　　　 4. Headlights with electric adjustment are rare.

　　　 GTL lighting in Ou Man adopts integrated headlights with lenses. It is commendable that its headlights have adjustable function, and the driver can adjust the illumination height of the lights inside the cab according to the weight of the cargo. This is the first time for domestic commercial vehicle manufacturers.

　　　 5. The front mask opening device has mixed opinions.

　　　 The opening device of Ou Man GTL front face mask is set on the front face, which means that the face mask can be opened without being in the cab. There may be different opinions about this design. However, Xiao Bian believes that even if it is opened, there is nothing to steal.

　　　 6. Modular design of pipeline layout-simplicity

　　　 When the mask is opened, it can be seen that the pipeline layout of GTL in Ou Man is in accordance with the modular design, and the cab adopts a four-point suspension airbag body suspension system to ensure the driver’s comfort during driving. Of course, the cab intake filter device, as a high-end model, is indispensable.

　　　 7. With a chrome-plated cover on the whistle, Fukuda is very kind.

　　　 The whistle is overhead, and a chrome-plated cover is added at the front end of the whistle, which also shows Ou Man’s "kindness" in workmanship. Its function is to prevent mosquitoes and rainwater from entering the whistle.

　　　 8. Ou Man GTL original fairing is quite powerful.

　　　 I feel that the work and quality of the spoiler components assembled on GTL in Ou Man are quite reliable, so I have specially "studied" them. The side plate of the spoiler can be folded inward, which is convenient for the driver to board the workbench for maintenance and operation.

●　 Ou Man GTL Interior: "Salute" to Mercedes-Benz Actros

　　　 Compared with the previous generation, the cab of GTL in Ou Man has been greatly improved in terms of internal space and comfort. Its interior is basically referenced, but some minor changes have been made in local positions. If it weren’t for the sign of Ou Man on the steering wheel, I would really think I got into an "improved" Actros. Let’s first test you with two pictures.

　　　 From the picture above, can you tell me which one is Ou Man GTL? Let me tell you, yes, it’s the picture on the left.

　　　 1. The cab layout imitates Mercedes-Benz Actros.

　　　 The main color of the cab is dark gray, and the local position is decorated with silver. Although the divisions of various functional areas have been slightly modified, it can still be seen that this is a replica of Mercedes-Benz Actros. If it weren’t for Fukuda’s LOGO on the steering wheel, I really thought I got into a Mercedes-Benz Actros.

　　　 2. High-end models can choose multi-function steering wheel.

　　　 The four steering wheels are designed with reference to Mercedes-Benz Actros, but the LOGO in the middle is changed to Fukuda’s. The steering wheel can be adjusted in four directions, and high-end models can also be equipped with a multi-function steering wheel, which can realize functions such as cruise control and volume increase and decrease of car stereo.

　　　 3. The top design is remarkable

　　　 A storage box, a player and some control buttons are designed in the front position inside the cab. As the flagship brand of Futian heavy truck, a skylight with insect-proof net is indispensable.

　　　 4. Standard (optional) airbag cushion seat to improve driving comfort.

　　　 The seat adopts airbag shock absorption, and the cab is suspended at four points. The driver’s driving comfort should be greatly improved, because it has not been measured and we are not sure. The right area of the seat is the gear lever and the parking brake operating switch.

　　　 5. The key layout is within reach.

　　　 The control buttons on the panel are all within reach, and the driver’s left-hand area is mainly designed with light height adjustment and backlight switch; The upper area on the driver’s right hand side is mainly composed of air conditioning knobs and control buttons; The lower area is the storage box and the cup holder.

　　　 6. The door design is simple, which improves the comfort of the legs when driving.

　　　 The lower part of the door is "clean" and there are not so many complicated settings, which makes the driver’s leg position more comfortable when driving. The driver’s door armrest integrates electric glass control, central locking, rearview mirror adjustment button, and high-end models are also equipped with mirror preheating function. The air outlet is spherical and can rotate 360 degrees or be completely closed.

　　　 7. Equipped with two power output interfaces with different voltages.

　　　 At the top of the center console, a trapezoidal storage box is designed, which can usually put some sundries. The air outlet and sundries box of the air conditioner are designed in the middle position, while in the lower position, besides the storage box, there are two power output interfaces with output voltages of 12V and 24V respectively.

　　　 8. Sleeper has more storage space.

　　　 As a driver’s other home, it is also important to rest during daily driving. Ou Man GTL high-top cab adopts double-deck sleeper. The left and right sides of the sleeper are equipped with storage boxes, reading lights and air conditioning outlets. The left side of the sleeper (driver’s side) is also equipped with keys such as cab light switch and air conditioning adjustment. The lower berth is divided into three independent storage boxes with partitions to facilitate the placement of tools.

　　　 9. The interior space is very spacious.

　　　 Ou Man GTL also has a major feature, and the drop of its internal stepped floor is very small. That is to say, the internal space is much larger than that of other domestic stepped floor models.

●　 Introduction of GTL chassis in Ou Man

　　　 The previous Fukuda Ou Man series models have always had the reputation of "no major faults, but no minor faults". Whether the appearance of GTL in Ou Man will change the brand image of Foton Ou Man Car Department is still unknown, and it is not easy to jump to conclusions. However, I am looking forward to Ou Man GTL giving us a good answer.

　　　 1. We will introduce some of them to you after the new car comes on the market.

　　　 2. The functional areas of the chassis are arranged compactly.

　　　 The Ou Man GTL we saw at the meeting place today is designed with a lightweight chassis. The front and rear steel plates are made of few leaf springs, and the front and rear axles are equipped with transverse stabilizer bars. The exhaust pipe, air storage tank, storage battery and urea tank are unknown from front to back on the left side of the car body; The right position is equipped with a largeCapacity fuel tankIt is worth mentioning that Ou Man GTL fuel tank is equipped with an independent heat source system, that is, a diesel boiler. Unfortunately, the oil-fired boiler assembled by GTL in Ou Man can only provide heating for the cab, but it cannot realize the preheating function of the water circulation system.

　　　 3. Saddle is adjustable and pipeline protection is in place.

　　　 The reserved hole on the girder allows the user to adjust the position of the saddle according to the requirements. The layout and protection of each pipeline are also in place.

●　 Editor’s note:

　　　 I believe there will be many different voices when Ou Man GTL goes public. However, judging from the appearance and interior design we saw today, the design of Ou Man GTL still took a lot of effort, and there is no complete "painting a tiger according to a cat". From the point of view of exterior modeling and interior coordination, it has greatly improved compared with previous Ou Man series models. However, we are more concerned about the performance of Ou Man GTL in future use. I hope this answer sheet can give us a satisfactory answer.

　　　 What do you think of GTL in Ou Man? Welcome to discuss with us.

　　No ability to coach, no time to coach, neither time nor ability to coach.

　　This spring, primary and secondary school students all over the country experienced a great learning migration. Once lively playgrounds and classrooms were silent, familiar deskmate teachers met online, and familiar blackboard books became electronic courseware.

　　With the arrival of the new semester, it is foreseeable that online classes will change from "freshness" to "new normal". From the first online course in Beijing 101 Middle School in 1996 to the present, all primary and secondary school students in China are online, and online education has been growing and popularizing. But at the same time, people also put forward higher requirements for online education. Online education also needs "self-evolution" on how to take educational value as the cornerstone and make full use of new technologies to improve students’ efficiency and reduce burdens.

　　"Self-evolution" of Good Teachers: From Fuzzy Experience to Accurate Data

　　What is a good teacher? The standards of each era are not the same.

　　In the past, a good teacher must have a solid classroom foundation and rich teaching experience. Grading homework and grading papers all the year round, so that they can walk the rivers and lakes with years of experience like old Chinese medicine practitioners. But in the era of online education, everything is changing gradually.

　　In the eyes of Liu Chang, the principal of the online school of learning together, students’ learning data has become the key to driving the whole teaching process. In the past, famous teachers relied on years of teaching experience, and one or two students could teach accurately according to their children’s learning characteristics. But once the number of students in the class is large, it is difficult for teachers to train according to the characteristics of each student. As a result, some children "do not have enough to eat" and some "can’t digest" in class.

　　"To a certain extent, this situation forces parents to sign up their children for off-campus training institutions."

　　Liu Chang believes that in order to solve the above problems, we must use information technology. Let each student learn data to form a user portrait, which is the key to drive the whole system to learn and improve continuously. Students produce a large number of data records in the daily learning process. Offline data can also be converted into online data through technologies such as photo correction and oral evaluation, and then analyzed through artificial intelligence technologies such as deep learning and data mining, so as to grasp the real learning situation of students.

　　Liu Chang believes that only when students learn data to drive real accurate teaching and bid farewell to "experiential" teaching can we truly "teach students in accordance with their aptitude".

　　In the front line of education, informatization has gradually penetrated into all aspects of learning. In the summer school of online school together, before each class starts, the lecturer will click on the students’ learning situation report to check the students’ weaknesses, and then design the specific content of this class to ensure targeted one-on-one explanation. After-class exercises will also be personalized according to the characteristics of students, so as to truly understand and master.

　　Obviously, a good teacher in the new era will gradually move from experience-based to data-based, and how to make better use of this information system and design a learning path for his students will become a standard to define a good teacher in the future.

　　"Self-evolution" of Good Tutoring: From Supervisor to Learning Companion

　　The parents of a student at Chengguan Primary School in Ganxian District, Ganzhou City, Jiangxi Province, have been running around for work all the year round. When he was young, he suffered from a low level of education, and he was unwilling to let his children go back to their old ways.

　　"Double-income workers like us have no time for counseling, and in the senior grades of primary school, I can’t do many questions. How can I help? Who will coach? " The parent said with emotion.

　　According to survey data, in China families, the difficulties parents encounter in their children’s extracurricular tutoring can be roughly divided into three types: no ability to tutor, no time to tutor, and neither time nor ability to tutor.

　　In essence, the tutor of the online school plays the role of the subject head teacher, taking the students to preview before class, following the students in class, and writing down the difficult points that the students feedback in the chat area. Although there is no need to make courseware, the tutor must also go deep into the subject system, knowledge points and test sites.

　　After class, the tutor can see the progress and accuracy of the exercises submitted by students in real time through the background, and give solutions to the weaknesses of different children.

　　How to be targeted and personalized? To this end, the online school of learning together launched the "Bian Que System" this year, which uses big data tools and teaching evaluation to make a systematic analysis of students’ homework, weekly test, monthly test and big test.

　　Tutors can learn about the weak links of specific students according to the evaluation situation and launch personalized education services. Different students in the same class may open the page of homework assignment, and the content may be completely different. Let the invalid and repetitive homework be greatly reduced, and the time for writing homework will also be shortened, thus reducing the burden on students.

　　Learn online school "Bian Que system" together.

　　Liu Chang believes that "a tutor who can combine the learning problems in school and open a small stove for students is a good tutor."

　　At the same time, tutors in the Internet age have to understand students’ age psychology, their hobbies, the characteristics of online language and their study habits. If you encounter a special family situation, the tutor even plays a bridge role between parents and students.

　　This "emotional teacher" may politely rush to hand in homework, or he may come to an online "home visit". The things that tutors worry about are very complicated, so parents and students can have a good user experience by doing their best and empathizing.

　　"Self-evolution" of a Class: From Standard Edition to Localization

　　It is hard to imagine that a parent in Baoan District of Shenzhen could not choose a good online class for his children under the dazzling array of online classes.

　　She said with a sad face: "The children said that the knowledge points spoken by the online school teacher are not the same as those spoken by the school teacher. After changing six online schools, her performance has improved to zero, and now she has been blacked out by these institutions. "

　　When choosing online courses, everyone has always taken brand, scale, teachers and price as the selection criteria, but it seems that the localization of courses has never been included.

　　What is a good course? According to Liu Chang, the principal of the online school, the first criterion of a good course is "adapting to local conditions". In other words, a course that is not adapted to local conditions is not a good course.

　　There are differences in the distribution and difficulty of knowledge points in different versions of textbooks, which will eventually be reflected in the examination papers. For students, not choosing localized textbooks is tantamount to taking a detour. If online schools can’t improve their grades quickly, the impact on students’ interest in learning will be enormous.

　　During the epidemic, the online school together created a super curriculum based on the local textbook version, covering the whole grade and the whole subject for primary and secondary school students who postponed their classes all over the country. This curriculum was praised and forwarded by many education experts, media people and teachers.

　　In addition to "adapting to local conditions", a good curriculum design should be "well documented".

　　Professor Chen Enhong of China University of Science and Technology believes that the use of artificial intelligence technology can promote the transformation of learning methods and teaching modes, build a new intelligent education system based on the Internet, and form an online learning and education platform integrating teaching, management and resource construction. To build an online learning education platform based on big data intelligence, it is necessary to build a learner-centered learning environment, develop a deep, intelligent and comprehensive learning analysis system, and provide accurate education and teaching services for teachers, students and administrators, which will help promote the development of personalized learning and lifelong learning, realize the rational and effective use of technology to promote learning and improve the quality of education.

　　With the help of the learning data of more than 100 million users in 160,000 schools in 31 provinces, which have been accumulated in the past 9 years of education and technology, the online school for learning together uses artificial intelligence technology to analyze and excavate, and integrates the difficulties, error-prone points and easy test sites encountered by students all over the country in their studies over the years into the curriculum design to help students complete their learning tasks quickly and efficiently.

　　From "pen tip" to "fingertip", the education system is undergoing an unprecedented change. When online classes are normalized, how to make new technologies better serve education, realize moral education and promote educational equity still has a long way to go.
