Investigation motive

　　"Delta Omicron Co-circulation", "Six Yangkang tourists in a scenic spot died of heart failure", "Beijing tap water is sunny" and "Express delivery industry closed on January 8 due to epidemic situation" … … For some time, there have been rumors about the epidemic-related network, distorting the national epidemic prevention policy, dispelling the people’s confidence in fighting the epidemic, seriously endangering social stability, and the people hate it.

　　Recently, the Central Network Information Office reported typical cases of epidemic rumors. The relevant person in charge said that it will continue to resolutely crack down on rumors and rumors, and strictly investigate and deal with account subjects who publish rumors. At the same time, relevant departments and netizens are welcome to actively participate in reporting, provide relevant clues, and work together to eradicate online rumors. Living soil.

　　Why are epidemic-related rumors repeatedly banned, why do some rumors come back after rumors, and how to effectively rectify and purify cyberspace? With these questions, the reporter conducted an in-depth investigation and interview.

　　□ Our reporter Zhang Shoukun Wen Lijuan

　　"Yangkang is not equal to health. Yesterday, several people died in Laojunding skiing, all of them were Yangkang, and suddenly they suffered from heart failure after strenuous exercise." Recently, the net spread "Qinhuangdao Laojunding Scenic Area ‘ Yangkang ’ The information that 6 tourists died of heart failure has attracted attention. After investigation, the news was false information. At present, the rumored woman Ma has been administratively detained by the police.

　　From "killing the whole city tonight" to "increasing chlorine injection into tap water", from "nucleic acid sampling is toxic" to "mask raw materials will cause pulmonary nodules", from "a positive man is transferred by crane" to "a container is used to operate a positive patient somewhere", from "the tap water will spread the virus" to "you can choose a mild strain to infect and produce antibodies" … …

　　In the investigation, the reporter of "Rule of Law Daily" found that every once in a while, all kinds of epidemic-related rumors circulating on the Internet will be "updated". Some of them deliberately misinterpret and fabricate epidemic prevention policies, and some carry out pseudo-popular science under the guise of science. Because they are related to the epidemic situation, these rumors can easily attract people’s attention and get a lot of attention and forwarding, which leads to many people’s doubts, anxiety, panic and other emotions, and even interferes with the normal epidemic prevention and control work.

　　A number of interviewed experts said that to rectify online rumors and purify cyberspace, we must further compact the platform responsibility, improve the information review and judgment mechanism, and control the release of epidemic-related rumors at the source; It is necessary to severely punish rumors according to law, and if serious consequences are caused, criminal punishment will be given.

　　Internet rumors about epidemic diseases continue.

　　Rumors make money by draining.

　　On New Year’s Day this year, Yin Kang, a citizen of Lianyungang City, Jiangsu Province, who opened the social software early in the morning, found that there were several rumors that had been continuously refuted in his social group and circle of friends.

　　At the end of the holiday, when I went to work, some colleagues told Yin Kang mysteriously with a bottle of Erguotou, that high alcohol can prevent COVID-19 infection. Would you like some? What bothers Yin Kang even more is that grandpa, who had given up smoking and drinking because of his poor liver and lungs, immediately asked his family to smoke and drink … …

　　Yin Kang said that although there are many rumors like this, people with discerning eyes know that they are false at first glance, but because of the rapid spread and wide range, some people, especially many elderly people, are willing to believe it. In addition, there are still many rumors that are cloaked in science, and the tone is so convincing that it is difficult for ordinary people to distinguish them.

　　Not long ago, WeChat Security Center announced the top ten rumors that were most widely circulated in the circle of friends in 2022, many of which were related to the epidemic situation, such as the toxic reagent on the "sampling cotton swab", the daily subsidy during the epidemic, and the prevention of Covid-19 by soaking Stephania in water. For Pan Ying in Nantong City, Jiangsu Province, these rumors are familiar to her.

　　"These top ten rumors have been forwarded by my family elders to the group. In recent years, I have been on the road of rumors, and I have tried my best to tell my family that these are false, but rumors have always existed, especially about the epidemic. This rumor has come again, and some rumors that have been rumored will come back after a while, and every rumor, no matter how outrageous, will always be believed by my family." Pan Ying said.

　　Recently, news about Covid-19 Omicron mutant XBB has been rampant. The latest news shows that the introduction of a new strain XBB.1.5 has been detected in Shanghai. At present, there are many rumors about XBB.1.5 on the Internet, especially a screen shot circulating on the Internet platform, saying that all the strains prevalent in China are the younger brother of XBB.1.5, which mainly focuses on cardiovascular and cerebrovascular diseases and will cause diarrhea. It is suggested that the public prepare montmorillonite powder, norfloxacin, rehydration salts, probiotics and so on. Shanghai rumor platform said that the screenshot exaggerated the pathogenicity of XBB.1.5, and did not rule out people with ulterior motives to promote products. Many doctors have warned not to take montmorillonite powder, norfloxacin and other drugs as mentioned in the screenshot at will.

　　In the investigation, the reporter found that since the epidemic prevention and control work was carried out, all kinds of information about the prevention and control of COVID-19 infection have always occupied an eye-catching position on social apps, websites and other network platforms, including many old and new rumors. Moreover, the rumors related to the epidemic have different distribution characteristics in different stages of the epidemic development, reflecting the changes in public sentiment and demand, which may make people have a wrong understanding of COVID-19 infection and adopt wrong means in the process of preventing and treating COVID-19, thus affecting the normal epidemic prevention and control work.

　　The Public Opinion Center of the Rule of Law Network conducted a public opinion analysis on Internet rumors about epidemic diseases caused by high fever, and found that social platforms have become a "Petri dish" for rumors about epidemic diseases. Most rumors about epidemic diseases come from social platforms and spread mainly through chat groups, friends circle, WeChat official account and video numbers, among which chat groups and friends circle are the main positions for communication. This is because the "strong relationship" social circle has the characteristics of privacy, closure, agglomeration, etc. The privacy of the acquaintance relationship chain makes it difficult to track the process of information production and forwarding, and at the same time, the credibility and forwarding volume of rumors are greatly increased, thus achieving cross-group and cross-platform communication. In addition, all kinds of short video platforms have become the new "source" of online rumors. The presence and authenticity of short videos increase the persuasiveness of rumors and often mislead the public to believe them.

　　Why are some publishers keen to fabricate rumors? The Network Security Bureau of the Ministry of Public Security has revealed this, and there will be advertisements inserted under the content released by the rumors or in the comment area. The more traffic advertisers are exposed and clicked, the more revenue they will get. "It can be said that every time you click, the rumor maker can make money."

　　Yin Kang said that many of his friends and family members feel that forwarding this information at will can remind more people, and it is a positive energy behavior. Even if it is false, it will not cause any losses to others. As a result, it has become a disseminator who has expanded the scope of rumors unconsciously.

　　Hair under the guise of official name

　　The platform is responsible for governance.

　　Recently, a notice claiming to be from "President of Changzhou Red Cross Society" spread widely. According to the notice, if brown sugar, ginger, scallion and garlic are boiled in water, the probability of being infected with the virus is almost zero. Li Lei of Heze City, Shandong Province has also received an "anti-epidemic prescription" from his old mother at home. However, Li Lei’s online verification found that the screenshot had been spread on the Internet as early as February 2020. At that time, the staff of Changzhou Red Cross Society rumored that the organization and the president had not released the above information.

　　"Most of them can be seen as rumors at a glance, and even a large part of them have been rumored by the government and proved to be rumors. I wonder why many rumors have been repeatedly banned, and some people are convinced of the rumors that have been rumored." Li Lei said.

　　Pan Ying said that she saw many rumors, all of which were published under the guise of official organizations. "I used to receive short messages informing me of nucleic acid testing and the health code turning red, which said that they were sent by the CDC and left a phone number. Some of them were true and some were false, so many people were cheated, which led me to doubt their authenticity as long as I saw the epidemic-related text messages now."

　　"There are too many rumors. We may remember them for a while after rumors, but we are not professionals. Most people may forget them in a month or two, and it is difficult to distinguish similar rumors when they come again." Pan Ying said.

　　According to Li Junhui, a special researcher at the Intellectual Property Research Center of China University of Political Science and Law, there are three main reasons for the repeated prohibition of epidemic-related rumors. First, epidemic-related information is the focus of public attention, which is related to the individual’s concern about how to avoid being infected and how to deal with it after infection. Second, it is related to the insufficient, untimely and incomplete release of epidemic-related information in some areas, because real information can not meet or solve public concerns, and it will naturally be attracted by some false information; Third, the information of epidemic-related rumors has the characteristics of confirmation, illustration or difficulty in distinguishing authenticity, which makes the relevant information easily misinformed and further misinformed.

　　What kind of responsibility may the rumor-monger bear for spreading rumors about the epidemic?

　　Ai Hongqiang, a lawyer of Beijing Jingshi (Quanzhou) Law Firm, told reporters that according to the Law on Public Security Administration Punishment, those who spread rumors, lied about dangerous situations, epidemics, police situations or deliberately disturbed public order by other means will face detention and fines. If a citizen’s personal reputation right is infringed by spreading rumors, according to relevant regulations, the infringer will bear the responsibility of stopping the infringement, restoring the reputation, eliminating the influence, apologizing and compensating for the losses. In addition, making and spreading epidemic rumors may also bear criminal responsibility.

　　At the end of November last year, the Central Network Information Office reported that in view of the recent rumors in the fields of epidemic prevention and control, emergencies, and people’s livelihood, it urged and guided the website platform to strengthen monitoring and verification, and the key website platforms handled more than 5,400 accounts for spreading rumors on the Internet, which was the first time. Trace the source and close the initial account.

　　Experts interviewed by reporters believe that the network platform has an unshirkable responsibility for the governance of epidemic-related information.

　　Li Junhui believes that the network platform should classify information, and make clear what belongs to the simple sharing of individual experiences and what belongs to the misleading information release. For all kinds of information released by users on the platform, a review and judgment mechanism should be established in time, and the experience sharing review with high similarity in information content should be strengthened to avoid spreading false epidemic-related information and causing public panic. For the release of rescue information, it is necessary to ensure that the rescue information can be released normally, and also to prevent criminals from simply copying and applying other people’s help information for release, which will affect public judgment.

　　The relevant staff of Tik Tok Platform told reporters that recently, during routine inspections, the platform found that a very small number of users posted content without medical basis, such as "COVID-19’s remedies for reducing fever — — Boiled soybean water to drink ","Smoked mugwort leaves and moxa sticks can wipe out Covid-19 ","Never eat food when you have a fever, including eggs and milk "and so on. The above contents have been refuted by authoritative media and medical experts. In this regard, the platform has given a continuous blow and treatment. Since November 2022, the platform has handled 332,600 false videos related to the epidemic and marked more than 200,000 suspicious contents.

　　Timely release of authoritative information

　　Crack down on epidemic rumors according to law

　　Recently, Shanghai Rumor-dispelling Platform has sorted out the recent rumors, classified them according to four major themes: prevention, symptoms, treatment and life, and attached suggestions and opinions from medical experts and authoritative organizations, hoping to present a practical "prevention and control book" for the public.

　　The reporter found that by searching for "epidemic situation" or switching to the "anti-epidemic" column on Tik Tok’s homepage, users can enter the epidemic prevention rumor area in Tik Tok and check the relevant knowledge; When Baidu searches with keywords such as "COVID-19" and "epidemic situation", there will also be a rumor-dispelling area and a national epidemic prevention hot search list to give users more scientific guidance.

　　The relevant departments have been taking action to crack down on rumors related to the epidemic.

　　Publishing and spreading false epidemic-related information through the Internet and deliberately creating and spreading epidemic-related rumors have seriously affected the normal public order. Hubei public security organs severely cracked down according to law and seriously investigated the relevant legal responsibilities of publishers, forwarders, group owners, administrators and other personnel.

　　On October 8, 2022, Huang, a citizen of Jianli City, Hubei Province, spread rumors about the epidemic in many social groups. Hu, a citizen of the city, forwarded it to his personal short video account without verification and spread again. The behavior of the two people caused panic among local residents and caused adverse effects. The Hongcheng Police Station in Jianli City organized a police investigation, quickly found the communicators Huang and Hu, and carried out legal education for them. The two clarified the rumor. In the end, the violator Huang was sentenced to five days’ administrative detention and Hu was sentenced to a fine of 200 yuan.

　　In November last year, the Network Information Office of Yulin Municipal Committee of the Communist Party of China and the Public Security Bureau of Yulin City of Shaanxi Province issued the Notice on Combating and Rectifying Internet Rumors Related to the Epidemic in accordance with the Law, prohibiting the compilation and distribution of false information and resolutely resisting online rumors. Website platforms, media people and Internet group administrators should strictly review the sources and contents of information related to the epidemic. If publishing and disseminating false information through the Internet has caused serious social impact, online letters and public security organs will crack down on relevant websites, platforms and Internet accounts according to laws and regulations.

　　Recently, Jiujiang City, Jiangxi Province officially issued a notice, and the information related to the epidemic is subject to the official information released by the epidemic prevention and control headquarters at all levels in the city. For the information related to the epidemic that has not been officially confirmed, it is not published, disseminated, commented, believed, rumored or spread. What has been published should be deleted immediately to actively eliminate the adverse social impact. If it cannot be deleted, it is necessary to promptly dispel rumors and take the initiative to explain the situation to the public.

　　According to Hu Gang, Deputy Secretary-General of internet society of china Legal Work Committee, at present, China has built a legal system of epidemic reporting, notification and publication, which is mainly based on the law on the prevention and control of infectious diseases and emergency regulations for public health emergencies, and a legal system of online rumor management, which is mainly based on the Civil Code, the Criminal Law, the Law on Public Security Administration Punishment, the E-commerce Law, the Network Security Law, and the Internet information service management measures, and has continuously carried out special actions such as "clearing and cracking down on online rumors and false information" to supervise the website platform to effectively perform information content management.

　　How can we make the rumors about the epidemic no longer "outcrop"?

　　Li Junhui said that in order to accurately crack down on false or rumor information related to the epidemic, it is necessary to have real and scientific information release subjects or strengthen the linkage between the regulatory authorities and platforms, and subjects with information screening ability and conditions should participate in the review of information release on various platforms to control rumor information release from the source. In addition, it is necessary to strengthen the big data analysis of information released by users, refine the focus of users’ attention, and timely release authoritative information to respond, so as to relieve or reduce public concerns. Those who are suspected of deliberately creating and spreading false information shall be investigated for legal responsibility according to law.

　　Hu Gang suggested that the early warning system of infectious diseases and the information disclosure system of infectious diseases should be improved, and the national information on legal infectious diseases should be regularly published by China CDC, and the disease control institutions at or above the county level should regularly publish information on legal infectious diseases in their respective administrative regions. When an infectious disease breaks out and is prevalent, the competent health department of the local people’s government at or above the county level shall publish the epidemic information within its administrative area; When infectious diseases break out and spread across provinces, the competent department of health in the State Council shall be responsible for the announcement. At the same time, to improve the website platform’s ability to accurately control the rumors of epidemic-related networks, Internet industry associations can build information sharing and joint punishment mechanisms, and those who repeatedly maliciously publish rumors can be punished by releasing information within a limited time or prohibiting the release.

Original grumpy little doctor Tencent medical code　

In Chinese over 60 years old, osteoporosis has reached 56%[1].

However, there is one disease that is more frequent than it-senile foot disease, the prevalence rate is as high as 87%, which seriously threatens the health of our parents [2,3].

However, only 7.3% people will take foot disease seriously and consult a doctor [4].

As the saying goes, "people get old when they are old", and when they get old, their legs and feet are awkward at first.

Time and tide wait for no man

With the increase of age, the muscle strength of the foot is weakened, the elasticity of ligaments becomes worse, or due to unsuitable shoes, it is easy to have problems such as arch collapse and hallux valgus [1-3]. As a result, the load-bearing capacity of both feet decreases.

(Made by myself)

2. Poor foot care

Old people, bad eyes, inflexible fingers, and inability to bend over will all lead to a common result-

Give up the care of your feet.

(Made by myself)

If the toenails are too long to be trimmed or washed, it may lead to problems such as too long and thick toenails and onychomycosis.

The most common foot diseases of the elderly are [6]:

Hypertrophy of toenails (41.3%)

Hallux valgus (commonly known as "big foot bone") (28.7%)

Dry skin (26.0%)

Corns and calluses (commonly known as calluses) (24.0%)

These problems will lead to a common consequence-

If you can’t walk steadily, you will fall easily.

Many elderly people are relatively fat, and their feet are heavily burdened when walking, which makes them easy to hurt, increasing the risk of falls and fractures.

Moreover, osteoporosis is a common disease in the elderly, and it is more likely to lead to hip fracture when falling-it is called "the last fracture in life" (the mortality rate of hip fracture is as high as 22%~30%, even 50%[7-9]).

American gerontologist Hazzard said: "A clear head and a pair of feet that can move freely can make the elderly live better." [5]

Inappropriate shoes are one of the reasons why the elderly fall, and more than 70% of the elderly have inappropriate shoes [10]. So, what are the main situations in which shoes are not suitable?

1. The shoes are too narrow

Toes and soles are squeezed for a long time, so that the forefoot is deformed, hallux valgus and little toe are deformed, which will be very painful.

(Made by myself)

2. The shoes are too short

It will bend the toes, which will be deformed after a long time (that is, hammer toes or claw toes).

(Made by myself)

The skin on the instep is squeezed, slowly forming a hard cocoon, which is painful and swollen.

Diabetic elderly people with poor blood sugar control are also prone to serious infections.

Let me say one thing first:

The so-called "shoes for the elderly" should be bought carefully to avoid paying the "filial piety tax".

Many "shoes for the elderly" are branded as breathable, spacious, soft, non-squeezing, and non-slip, and can even be like twisting a towel.

(Made by myself)

But in fact, the softer the shoes, the better. Shoes that can be easily twisted are easy to deform and lack support for the arch.

When buying shoes for the elderly, we should follow the principle of "wide front, tough middle and hard heel".

Specifically, the elderly should pay attention to these three points when choosing shoes:

1. The sole has anti-slip design.

Older people’s physical balance ability becomes worse, and the perception of pressure on the soles of their feet decreases, which will increase the risk of falling when walking [5].

Therefore, it is necessary to choose a non-slip design for the sole.

2. Hard soles with sufficient support

Shoes that are too soft, such as old cloth shoes, lack sufficient support at the arch, and it is easy to feel uncomfortable when walking too much, and the feet are tired, sore and painful; Encountering a gravel road will also increase the risk of falling [11,12].

Hard-soled shoes can increase the safety and stability of the elderly when walking [13].

The middle toughness of shoes should be moderate, and you can try to twist them by hand. It is not good to twist them too easily or completely.

The heel also needs to have a certain height, at least 1.5~2.5 cm, which can disperse the pressure on the sole of the foot.

3. The vamp should be breathable, warm and loose.

Old people’s feet have poor blood circulation and are prone to cold feet, pain, blue skin and other symptoms [11].

Buying a pair of breathable, warm and loose shoes is comfortable and easy to wear, and it can also reduce the incidence of nail malnutrition and fungal infection (commonly known as beriberi) [5].

It can be a little bigger, leaving about 1 cm in front of the toes, so that the toes have enough room to move.

In addition, when the elderly buy shoes, there are three tips:

1. It’s best not to buy it by children or online shopping, but to try it yourself.

Bring socks and insoles that you usually wear. Feel it on your feet and experience walking, running and jumping in the store to choose the shoes that suit you best.

It’s best to buy it in the afternoon

Affected by gravity and venous reflux, people’s feet are usually bigger in the afternoon than in the morning.

Trying on shoes in the morning will hurt your feet in the afternoon [5].

Don’t bother, try more pairs.

Old people often encounter two feet with different sizes, for example, one foot has severe hallux valgus, or the arch of both feet collapses to different degrees.

This requires trying on a few more pairs and finding shoes that are comfortable for both feet. Or put an arch support pad on a shoe.

　　Published in China Newsweek magazine, No.1132, March 18th, 2024.

　　On March 1st, Premier Li Qiang of the State Council presided over the the State Council executive meeting, which discussed and adopted the Action Plan for Promoting Large-scale Equipment Renewal and Trade-in of Consumer Goods. The meeting pointed out that "promoting a new round of large-scale equipment renewal and trade-in of consumer goods is a major decision made by the CPC Central Committee focusing on the overall situation of China’s high-quality development".

　　In 2023, China’s exports denominated in US dollars decreased by 4.6% year-on-year, which was the first year-on-year negative growth since 2016; Domestically, due to the downturn in the real estate market, the growth rate of investment has also declined. The decision of "trade-in" of consumer goods is put forward in the current complicated domestic and international environment, hoping to play a role in "stabilizing and expanding traditional consumption".

　　The meeting pointed out that this round of "trade-in" should "combine the differentiated needs of upgrading various types of equipment and consumer goods, and increase fiscal, taxation, financial and other policy support". In terms of related fields, "actively carry out the trade-in of consumer goods such as automobiles and household appliances, forming the scale effect of upgrading". It can be seen that this round of "trade-in" is more focused on bulk consumption represented by durable goods. Different from the consumption stimulus policies such as automobile tax reduction and exemption since the epidemic, the meeting clearly pointed out that it is necessary to form a "scale effect of upgrading", indicating that the strength of the policy is unprecedented and the goal to be achieved is clear.

　　Similar to the "home appliances going to the countryside" that began at the end of 2008, this round of "trade-in" is partly due to the decline of external demand, which is intended to expand the domestic demand market and stabilize economic growth. The difference is that, first, the demand is different. If "home appliances going to the countryside" is to meet the rigid demand of residents’ life, then this round of "trade-in" is to meet the improvement demand, and further improve the standard and improve the quality of life of residents on the premise that the basic living materials of residents are met; Second, the target groups are different. "Home appliances going to the countryside" is more about filling the gap of rural household appliances, that is, it is aimed at the problem of insufficient supply of rural household appliances, but this problem does not exist in this round of "trade-in". At present, even rural families have already achieved the popularization of household appliances, and the target groups of this round are mainly the owners of existing durable consumer goods such as cars and household appliances.

　　In view of the characteristics of this round of "trade-in", it can be promoted from the following aspects:

　　First, introduce a relative "elimination" model. This round of "trade-in" is aimed at improving demand, and consumers have greater selectivity than just needed. In the face of the downward pressure of economy, most consumers have the psychology of delaying consumption in the face of improving consumption of durable goods with large expenditure. To ensure that the policy achieves the "scale effect of upgrading", it is necessary to increase policy support for some commodities. For automobile consumption, we can give more subsidies and tax incentives to certain types of vehicles, such as new energy vehicles, and promote the popularization and improvement of other supporting facilities needed for this type of vehicles. For consumer goods such as household appliances, the relative "elimination" mode can be introduced through the formulation of corresponding exchange rules, so as to promote trade-in and reduce delayed consumption. For example, through the formulation of exchange standards, the circulation value of old household appliances can be clarified, and then the relative elimination cost of old household appliances can be clarified, so as to promote residents to deal with the consumption of old household appliances as soon as possible and reduce the delayed consumption of household appliances.

　　Second, set standards as soon as possible. "Trade-in" first needs to set the standard of "exchange" to meet the needs of different groups, and the standard can be set from different dimensions. From the dimension of consumer goods, it is necessary to set the standard of "old" exchange for "new"; Different subsidies, discounts and exchange standards can also be set for "new", even if the preferential strength is not great, it will have the effect of forcing manufacturers to upgrade their products.

　　The purpose of "trade-in" is to improve the quality of life of residents, but it does not mean wasting. Therefore, in the process of "trade-in", we should really consider the rights and interests of consumers and the allocation benefits of resources.

　　First, strengthen the recycling of durable goods and develop circular economy. Exchange is divided into two parts: recovery and reuse. The "recycling" part is to exchange the old for the new, which mainly involves the formulation of standards and the operation and maintenance of platform accounts, and the "reuse" part is to further improve social utility through the differentiation of improvement needs. In view of different personal preferences and consumption levels, the performance of some replaced old consumer goods may still be better than that of new consumer goods with relatively low prices. In this way, through reasonable points exchange and the construction of second-hand platforms, both parties can obtain satisfactory results and further improve the effectiveness of both parties. The significance of building the "exchange and recycling" platform lies in improving the liquidity of durable goods such as household appliances, speeding up the process of eliminating and upgrading household appliances, promoting the consumption of durable goods, and improving the quality of life of floating population and renters. The circulation of second-hand household appliances is especially beneficial to the development of the housing rental market and promotes the flow of talents.

　　Second, we should respect the property rights of residents’ private property. Household appliances and automobiles are the private property of residents, and they are generally "big items" in household durable goods, with high value, accounting for a relatively large proportion of residents’ property. We should earnestly consider the rights and interests and economic situation of existing consumer goods owners, resolutely put an end to the practice of forcing household durable goods to be scrapped by means of laws and administrative orders, and effectively protect the property rights of residents. "Trade-in" should be implemented on the basis of residents’ willingness. The design and implementation of policies should ensure the realization of "Pareto improvement", that is, the welfare of some people can be improved without harming the welfare of others.

Feng Yuyi, a trainee reporter of Southern Finance and Economics, reports from Zhuhai.

In the era of Industry 4.0, AGV/AMR (Mobile Robot for Industrial Application) has become a vital part of industrial production intelligence, and gradually penetrated into manufacturing, logistics and service industries, and the charging industry promoted by this is in the cusp of vigorous development.

At present, the 100 billion-level charging and power market formed by new energy industrial vehicles such as mobile robots, mining machines, low-speed unmanned vehicles and lithium-ion forklifts, as well as the continuation market of secondary sales of charging modules, power batteries and replacement of charging equipment, are accelerating.

According to the forecast of AGV/AMR industry alliance, it is estimated that the new AGV/AMR in China will exceed 120,000 units in 2023, and the new market will exceed 200,000 units in 2025, with a market scale exceeding 45 billion yuan. The compound growth rate of sales in the next five years will remain above 40%. Among them, AGV/AMR charging and power system are two important systems of electric industrial vehicles, accounting for over 8%.

"Electrification and intelligentization of industrial vehicles are the general trend. Even though industrial manufacturing has faced various difficulties in the past three years, the AGV/AMR charging industry is still in a period of rapid growth with strong demand and full of resilience. With the diversified application scenarios of mobile robots, the penetration rate of the charging industry will be further improved. " Recently, Zou Jianjun, founder, chairman and CEO of Guangdong Titan Intelligent Power Co., Ltd. (referred to as "Titan Intelligent"), said in an interview with Southern Finance and Economics all-media reporter.

Founded in 2016, Titan Intelligence is a state-level specialized and new "Little Giant" enterprise focusing on providing overall energy solutions and back-end data services for new energy industrial vehicles. In the context of rising industry demand and maturing technology, Titan Intelligent won the A round of financing from Zhuoshi Investment in 2022.

Compete for product pricing power

At the beginning of Titan Intelligent’s entry into the new track, it coincided with the wave of "oil to electricity" and "lead to lithium" for industrial vehicles. Under the market reform dividend brought by the "double carbon" background, Titan Intelligent stood out and quickly opened the market with its research and development capabilities and market sense.

When talking about why the track was chosen, Zou Jianjun said, "In the process of a customer chat, it was found that the AGV/AMR charging industry is generally a’ one-price’ sale, which is completely a market where the seller has the pricing power." After market research, he found that the domestic AGV/AMR and the charging products of electrified industrial vehicles were almost all imported from abroad. Although the domestic market demand was huge, there was no bargaining power.

After gaining insight into this new market trend, Titan Intelligent accelerated its layout research and development with AGV/AMR and intelligent lithium-ion charging equipment and batteries for electrified industrial vehicles as the main business, and the annual investment in research and development accounted for about 10% of its main business income. In a few years, Titan Intelligent Power has successively launched the digital intelligent charging series for industrial electric vehicles, the side charging and charging integrated machine series for intelligent manipulator of mobile robots, the power battery series for mobile robots, the power battery series for low-speed unmanned vehicles, the power charging series for low-speed unmanned vehicles, wireless charging for mobile robots and other efficient and stable overall charging solutions. The application scenarios involved run through all links of the whole industrial chain, and cover application places such as logistics and transportation, smart home appliances and public infrastructure.

"Although we started later than foreign countries, relying on China’s R&D foundation and industrial chain advantages in the field of new energy charging, we quickly mastered the right to speak in the industry in the game with foreign products, let the price return to a reasonable range, and achieve the domestic market share. First." Zou Jianjun said that more and more foreign manufacturers began to choose to use Titan smart products.

According to reports, while entering the mainstream AGV brand manufacturers in China, including Hangcha Group, Heli Forklift, Kuka Robot, Xinsong Robot, BYD, etc., Titan Intelligence has also obtained international qualification certifications such as cTUVus and CE, and is exported to 195 countries and regions such as America, Europe, Africa, Southeast Asia and Australia, reaching a global coverage rate of 85%. Internationalization has become one of the ideas of Titan’s intelligent "by going up one flight of stairs". Zou Jianjun said, "The forklift truck for lithium battery industry is our important market. 70%-80% of the demand is overseas. Expanding business overseas is equivalent to catching this blue ocean market."

According to the data of Chinafork. com, the global forklift market will be about 150 billion yuan in 2022, including 110 billion yuan in overseas market and 40 billion yuan in domestic market. Domestic forklifts mostly use lithium battery as the main power, and the trend of replacing lead-acid battery forklifts in foreign markets has accelerated significantly, or it will usher in important development opportunities.

With the iterative upgrading of new energy battery technology, it also brings more room for improvement for the mobile robot industry, and is highly expected in reducing costs, improving efficiency, and industrial transformation and upgrading.

Based on long-term observation of the market, Zou Jianjun bet on lithium iron phosphate battery. Titan Intelligent established a subsidiary-Zhuhai Titan Lineng Technology Co., Ltd., and has its own PACK factory, which mainly develops and produces AMR and AGV power lithium battery packs, further improving the overall solution of the power system.

In Zou Jianjun’s view, compared with traditional lead-acid batteries, lithium batteries have the advantages of lighter weight, smaller volume and higher energy density, so the lithium battery forklift model is more compact and the vehicle stability is higher. "And in recent years, the acceptance of lithium battery forklifts by end customers, especially high-end customers, has steadily increased. We believe that the future development prospects of the lithium battery market are very broad."

Explore and create a new model of "energy products+data services"

Walking into the research laboratory of Titan Intelligence, the wireless charger, which is called the "charging treasure" of the mobile robot, is executing the command set by the wireless energy emitting device, and automatically recognizes charging from a distance after finishing the workflow. A series of actions are flowing, and fully automatic and intelligent charging can be realized without connecting vehicles.

This is the research and development site of Titan Intelligent’s autonomous intelligent AGV charging system based on magnetic coupling resonant wireless charging technology, which has no electrode oxidation and fouling, reduces the charging accident caused by poor electrode contact, not only improves the safety and applicability, but also makes AGV charging products more intelligent.

Zou Jianjun revealed that the high-power wireless charger series independently developed by the company has built technical barriers in coil design, circuit research and core algorithm. At present, it has completed the verification in the laboratory stage and will go to the stage of commercialization and mass production next year. "The era of wireless charging has arrived, and it is expected that there will be an outbreak in the next five to ten years."

Compared with wireless charging of electric vehicles, AGV wireless charging requires fast charging mode with low voltage and high current, and the main challenge is to require small size, high efficiency and high cost performance. Zou Jianjun introduced, "We combine AGV battery and wireless charging to build an overall AGV power system, realize modular development, reduce the volume by 50%, and continuously improve the product stability, which is our design idea and core competitiveness to fundamentally reduce costs."

At present, the industrial wireless charging technology track targeted by Titan Intelligence is becoming increasingly hot at home and abroad. According to the incomplete statistics of Southern Finance and Economics reporters, there are already manufacturers in the domestic market, such as Baiyi Technology, Luyu Energy, Avant-garde Wireless, Qingdao Paworth, Taihang Jiaxin Electric, etc., who have laid out new technologies, and new scenes and new applications are constantly opening up. In foreign markets, Tesla announced in June this year that it plans to acquire Wiferion, a German manufacturer that provides wireless charging technology for AGV/AMR.

While Titan Smart continues to increase its research and development of wireless charging systems, the team is constantly exploring innovations in business models.

In recent years, with the blessing of AI, mobile robots have been continuously upgraded intelligently, becoming the "nerve center" of the digital intelligent transformation of traditional manufacturing industry, which is expected to usher in large-scale applications in new energy vehicles, new retail and big health fields.

Facing the future, Titan Intelligence is building a general power platform for mobile robots, equipped with wireless charging system, power system, drive control system and background data management system, exploring software and hardware technologies, and establishing a development model of "energy products+data services".

Zou Jianjun believes that mobile robots must be one of the best carriers of AI applications, and connecting mobile robots with data services "chain" will be the development trend of the future industry.

In Zou Jianjun’s view, AGV charging product providers not only supply mobile robot parts, but also provide end customers with overall energy solutions from warehousing transformation to material docking and maintenance services. "This requires analyzing the density and quality of information collected by mobile robots from the data level to build a new ecosystem, which is also the underlying logic of our layout of this emerging business."

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.

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.

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

The second hand-painted dream map

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.

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

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.

Read the original text

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.
