The frequent emergence of antibiotic resistance challenges modern medicine. It is very important to discuss the evolution of resistance to curb its global spread. The evolution of resistance involves a highly complex phenotypic heterogeneous response. Under the treatment of antibiotics, a small number of antibiotic-tolerant cell subsets will appear in the microbial flora with identical genes. The surviving subgroup can’t grow in the presence of antibiotics, but it can grow again after removing antibiotics, resulting in long-term recurrent infection, which is also the key reservoir for subsequent mutation of resistance genes. However, due to the complex heterogeneous response and stagnant growth of tolerance subgroups, it is still a challenge to identify tolerance subgroups from a large number of bacterial populations and track their physiological evolution trajectory.　
　　Recently, the team of Academician Zhu Yongguan from the Institute of Urban Environment, Chinese Academy of Sciences and Cui Li’s research group published in German Applied Chemistry. A research paper entitled an isotope-labeled single-cell Raman spectroscopy approach for tracking the physiological evolution of bacteria towards biological resistance was published. In this study, the heterogeneity of bacterial response was analyzed in situ at a high-precision level by developing a combination of single-cell Raman-deuterium isotope-multivariate statistical analysis, and the differentiation and dynamic changes of phenotypic subsets were sensitively identified from a large number of bacterial populations, which realized the rapid in-situ tracking of bacterial phenotypic physiological trajectory before resistance mutation, providing important guidance for curbing resistance evolution.　
　　In this study, bacteria were repeatedly exposed to clinical therapeutic doses of antibiotics, and antibiotic resistance evolved. In this paper, the in-situ activity of bacteria during evolution was detected by Raman spectroscopy of single cells labeled with heavy water in a culture-independent way. The results showed that the activity of bacteria under antibiotic pressure gradually increased with the treatment cycle without resistance mutation, indicating that its phenotypic tolerance gradually improved. Furthermore, the study uses UMAP multivariate statistical algorithm to analyze the single cell Raman fingerprint interval of thousands of bacteria in all evolutionary stages. According to the physiological response of bacterial phenotype indicated by Raman fingerprint, four phenotypic subgroups differentiated with the evolution of resistance were identified from bacterial populations with identical initial genotypes, namely sensitive flora, primary tolerant bacteria, evolution tolerant bacteria and evolution resistant bacteria, and the dynamic changes of the four subgroups with the evolution process were sensitively captured. So far, based on the heterogeneous response of bacteria in situ phenotype revealed by single cell Raman, researchers have drawn a physiological trajectory map of resistance evolution. Genome-wide sequencing of bacteria verified the revealed phenotype interactively, and analyzed the genetic basis of phenotype. Phenotypic differentiation is very important to maintain the survival and evolution of the whole flora. Because phenotypic differentiation is much earlier than resistance mutation, identifying phenotypic differentiation is of great significance for guiding clinical medication and reducing the occurrence of antibiotic tolerance and resistance mutation. In this study, the Raman spectra of four distinct subgroups were used to dig out the Raman marker peaks of tolerance and resistance mutation, which promoted the rapid and accurate identification of different stages of resistance evolution, especially phenotypic tolerance.　
　　The single cell analysis platform can be extended to a wider range of research on the evolution of resistance induced by antibiotics or non-antibiotic chemicals. In the future, the single-cell Raman can be combined with targeted single-cell sorting and multi-omics technology to realize the accurate correlation between tolerance and resistance phenotype and genotype, and promote the further explanation of evolutionary mechanism. The research work is supported by the "0 to 1" original innovation project of Chinese Academy of Sciences, the innovative research group project of National Natural Science Foundation of China and Fujian Natural Science Foundation.

　　Tracking the evolution of bacterial antibiotic resistance by single cell Raman-isotope labeling-multivariate statistical analysis

　　Xinhua News Agency, Beijing, August 8th Question: Did you go to the swimming pool without changing your shoes, the bacteria exceeded the standard by 5 times, and the lifeguard deserted? — — Investigation on hidden dangers of safety and hygiene in swimming places

　　Xinhua News Agency reporters Yan Zhihong, Li Yuze, Dong Xiaohong and Yang Na.

　　It’s midsummer, and swimming and fitness are very popular. Not long ago, the National Health and Wellness Commission issued the "List of Unqualified Places for Swimming Pool Water Quality Spot Check in Some Cities (First Batch)", which showed that some swimming pools in many cities were not up to standard.

　　National Fitness Day is coming, is there any hidden danger in the swimming pool you choose? What skills can help us choose a safe and hygienic swimming pool? Xinhua news agency reporters launched an investigation for this.

　　Chaos, Dirty and Danger: There are still many "swimming" problems in various places.

　　A few days ago, a suspected chlorine leak occurred in a swimming pool in Fangshan, Beijing, which caused many people to feel uncomfortable. At the same time, it made people feel palpitation, but it did not stop people from questioning whether the swimming pool around them was safe and hygienic. The reporter conducted field visits and investigations in Nanjing, Chengdu, Xiamen and other places, and found that there are still obvious hidden dangers in many swimming pools.

　　— — "Chaos". During the visit, the reporter found that some swimming venues did not publicize relevant information as required, and some swimming pools did not properly implement the cleaning procedures before entering the pool. In the Yingpaisi Swimming Pool in Gulou District, Nanjing, the reporter found that except for the residual chlorine content and water temperature of the venue, the self-inspection items stipulated in the national health standards such as the pH value and testing time of the swimming pool were not publicized, and other important data directly related to the health of swimmers, such as turbidity, carbon, total bacteria and coliform bacteria, were not announced. The reporter also saw that many visitors crossed the disinfection and sterilization facilities and directly entered the swimming pool. In addition, there are many people who directly wear slippers or even enter the pool without changing their shoes at all.

　　— — "dirty" The total number of bacteria in some swimming places exceeded the standard, causing adverse reactions among minors. "Several dolls in the class vomited and diarrhea after swimming." Many parents told reporters that after their children learned to swim in the miracle gym in Xindu District, Chengdu, they developed symptoms of fever and upper respiratory tract infection. According to the sampling results of local law enforcement departments, the total number of bacteria in the swimming pool water of the museum reached more than five times the upper limit of the standard value.

　　— — "risk" Some swimming pools are not equipped with life-saving personnel, and some lifeguards "desert". In the Yingpaisi Swimming Pool in Nanjing, the reporter found that during the peak hours of passenger flow on the weekend afternoon, there was no lifeguard in the audience for a long time. When some lifeguards are on duty, they often leave their posts or talk and laugh with their backs to the pool for a long time.

　　Excessive profit-seeking, poor management and weak supervision have become the main causes of "swimming"

　　The reporter’s investigation found that excessive profit-seeking, poor management and weak supervision are the main reasons for the safety and health hazards in some swimming venues in many places.

　　Some swimming venues ignore safety and hygiene standards in order to reduce costs. According to the requirements, swimming venues should be cleaned once a month. A coach of Nanjing Yingpaisi Swimming Pool revealed: "Swimming pools in the market are simply difficult to do." He told reporters that it takes two or three days for a small and medium-sized swimming pool to change water, and it takes longer for a large swimming pool. Not to mention the cost of changing water, the time cost is unbearable for commercial swimming pools. Therefore, in order to maximize profits, some swimming pools often try to reduce the frequency of changing water and washing pools.

　　In addition, some swimming pools "hide" in the community, so it is difficult to implement dynamic supervision. Wu Xiang, deputy head of the Environmental Health Supervision Brigade of Chengdu Health and Family Planning Supervision and Law Enforcement Detachment, said that although the facilities and environment of swimming pools (gymnasiums) in some communities are "superior", there are many water quality problems. For example, the residual chlorine value is lower than the national health standard, and the foot soaking pool does not meet the relevant health standards. He said that this swimming pool is usually "hidden in the building" and it is very difficult to implement dynamic supervision.

　　In addition, the rapid increase of passenger flow in summer and the lack of hard constraints on uncivilized swimmers are also the causes of the problem. In the Xiamen Workers’ Sports Swimming Pool, the reporter saw that the current water permeability of the swimming pool was significantly lower than other times. To this end, Chen Hong, deputy director of Xiamen Workers’ Cultural Palace, explained that the current peak season ticket prices are low, and the sudden increase in passenger flow has brought great pressure to management. The museum replaces more than 100 tons of fresh water for the swimming pool every day, but it still can’t eliminate the pressure of maintaining water sanitation. In addition, Chen Hong also said that there is currently a lack of hard constraints on uncivilized behavior in swimming pools. "We can only euphemistically discourage related uncivilized behaviors, and there is nothing else we can do."

　　In addition, the reporter also learned that due to the lack of effective due diligence supervision mechanism for lifeguards, lifeguards "deserted" a lot, which increased the safety risk.

　　Master these tricks and choose a safe and hygienic swimming pool.

　　The staff of relevant authorities in many places reminded that ordinary swimmers who want to choose a safe and hygienic swimming venue for "cool summer" must master certain skills to identify the safety index because of the lack of professional testing equipment.

　　The first is inspection. The majority of swimmers should take the initiative to check whether the health permit is hung in a conspicuous place and check whether it is within the validity period. We should try our best to know the health quantitative grading rating, the history of water quality sampling and the real-time self-inspection of water quality in swimming places in time, and pay special attention to whether the safety equipment and personnel in the venues are in place, so as to choose a suitable swimming place.

　　The second is the view. Observe whether the sanitation around the swimming pool is clean, bright and ventilated, and whether there is water in the drainage ditch. Besides, it depends on the color of the pool water. If the residual chlorine content in the swimming pool is normal and the water quality is excellent, then the pool water is bright light blue. And the water in the pool should be crystal clear to the naked eye.

　　The third is to smell. Is close to the surface of the water to smell the smell of water, if you can smell the faint smell of chlorine, it is qualified, and the medicine is too strong or even choking, then the concentration of available chlorine may exceed the standard.

　　The fourth is feeling. After entering the water, if the water quality of the pool is excellent, it will feel soft. If it feels hard and astringent, or even itchy, the water quality may be poor.

　　At the same time, a number of swimming venue operators have called for the majority of swimmers to consciously swim in a civilized way and jointly safeguard the health and safety of swimming pools. They suggested that the management department should introduce hard restraint measures against uncivilized swimmers who have repeatedly taught, so that civilization can be implemented and the pool can be cleaned.

　　In addition, the reporter learned that swimmers can also check the sanitary condition of the swimming pool around their location through some apps, and can check the water temperature, pH value, average daily water change rate, residual chlorine in the swimming pool and so on.

Cctv news(Reporter Li Wenxue, reporter Gao Peng) On November 14th, a woman in Jiamusi City, Heilongjiang Province was defrauded by a liar posing as a public security inspector, and more than 340,000 yuan in her bank card was almost transferred to the other party. At the last moment, the police of Xiangyang Branch of Jiamusi City Public Security Bureau dissuaded and stopped it in time, so that it avoided heavy losses.

At 20 o’clock on November 14th, Ms. Wang went to Xilin Police Station of Xiangyang Public Security Bureau for help. According to Ms. Wang, at about 17 o’clock that day, a staff member who claimed to be a public security organ in Shanghai called to inform him that his identity card had been stolen by a fraud gang for fraud, and he needed to cooperate with the investigation and was equipped with an electronic confidentiality agreement.

The swindler asked Ms. Wang to use her mobile phone to download the mobile app sent by the other party, and then asked Ms. Wang to provide a bank card account number and password, and at the same time transferred all the funds in the remaining bank cards to the bank card, and asked Ms. Wang to keep it confidential and not allow outsiders to intervene. Ms. Wang listened to the other party and transferred the remaining funds in the bank card totaling more than 340,000 yuan to the bank card provided to the other party, and informed the other party of the bank card account number and password. Subsequently, the other party asked Ms. Wang to untie the bank card and ask for a verification password.
　　　　At this time, Ms. Wang realized that she might be cheated and immediately went to the Xilin police station of Xiangyang Public Security Bureau for help. After being dissuaded by the police in time, Ms. Wang canceled the bank card unbinding verification code to be sent soon, and with the help of the police, frozen the bank card funds, so that the funds in the bank card could not be transferred out.
　　　　Police tips:Public security organs will never use telephone to investigate and deal with so-called suspected crimes, bank card overdrafts and other issues, and there is no so-called "safe account". Don’t believe anyone who asks for bank transfer or remittance of deposits by phone or SMS, or claims to conduct fund review.

　　On the first day of Tesla’s founder and CEO Elon Musk’s arrival in China, Tesla welcomed the benefits.

　　On April 28th, China Automobile Industry Association and National Computer Network Emergency Technology Processing Coordination Center issued the Notice on Testing Four Safety Requirements for Automobile Data Processing, and all the models produced in Tesla Giga Shanghai met the compliance requirements. Previously, Tesla had realized local data storage in Tesla Shanghai Data Center in 2021. In addition, Tesla introduced a third-party authority to audit the company’s information security management system and passed the security management system certification (ISO27001).

　　Musk said on the social platform on April 28 that Tesla will invest about 10 billion US dollars in AI training and reasoning in 2024, and the latter is mainly used for automobiles. If any company can’t reach this level of expenditure and can’t spend efficiently, it can’t participate in the competition.

　　Six car companies, including Tesla, passed all four requirements of national automobile data security.

　　At the invitation of the China Council for the Promotion of International Trade, on the afternoon of April 28th, Tesla founder and CEO Musk arrived in Beijing. Musk said that he was glad to see the progress of electric vehicles in China, and all cars will be electric in the future. On April 28th, Tesla issued a document saying that it will continue to deepen its cultivation in China, develop together with the industry in the fields of artificial intelligence, electric vehicles and energy storage, accelerate the landing of clean energy and autonomous driving technology, and turn the beautiful vision into reality.

　　On April 28th, the Technical Department of China Association of Automobile Manufacturers disclosed the notification on the detection of four safety requirements for automobile data processing (the first batch). According to the report, there are six car companies, including (), Ideality, Lotus, Hezhong New Energy, Tesla and Weilai, and a total of 76 models meet the four compliance requirements for automotive data security.

　　According to the circular, in order to standardize automobile data processing activities, protect users’ legitimate rights and interests, encourage head car manufacturers to play a role as a benchmark, and promote the formation of a good environment for the whole society to jointly safeguard automobile data security and promote the development of the automobile industry, China Automobile Industry Association and the National Computer Network Emergency Technology Processing Coordination Center are based on the "Several Provisions on Automobile Data Security Management (Trial)" and GB/T 41871-2022 "Information Security Technology Automobile Data Processing Safety Requirements" and other laws and standards, and in accordance with the principle of voluntary inspection by enterprises. Since November, 2023, we have organized the inspection of automobile data safety compliance of newly listed intelligent networked vehicles of automobile manufacturers in 2022-2023. This test covers four compliance requirements, such as anonymous processing of external face information, default not to collect cockpit data, in-vehicle processing of cockpit data, and significant notification of personal information.

　　Notice on the Detection of Four Safety Requirements for Automobile Data Processing disclosed by the Technical Department of China Automobile Association

　　Some senior auto industry analysts analyzed the Shanghai Stock Exchange reporter, and this incident released two signals: 1. The state has formulated clear rules for auto data security. 2. All car companies are treated equally before the rules, including wholly foreign-owned car companies. "Obviously, this will help foreign investors to invest in China and further expand their investment in China. At the same time, it also shows that the state has been making efforts to improve the foreign investment environment. "

　　Tesla FSD landing requires data acquisition and other preparations.

　　On April 28th, Musk, who just arrived in Beijing, said on social media that Tesla will invest about $10 billion in AI training and reasoning this year, and reasoning is mainly used in cars. Musk said that any company that spends less than $10 billion a year or cannot deploy it efficiently cannot compete in the market.

　　In January, 2024, Tesla added $500 million in new investment and purchased about 10,000 NVIDIA H100 GPU for the training of autonomous driving. According to statistics, Tesla may have more than 30,000 H100 GPU. Musk recently said that Tesla may be the second company with the number of H100 GPU in NVIDIA, second only to Meta, and xAI ranked third.

　　Tesla’s heavy investment in AI is aimed at the future business opportunities of autonomous driving. Musk said that Tesla will launch a driverless taxi on August 8, 2024. Recently, Tesla gradually began to push to North American users on a large scale based on end-to-end FSD V12. FSD V12 achieves the goal of autonomous driving through a large amount of video training data, which enables Tesla to save hundreds of thousands of lines of code. However, training such AI autopilot requires a lot of computing power. Musk said in August, 2023 that Tesla will soon launch a GPU cluster consisting of 10,000 NVIDIA H100′ s to train the new FSD system.

　　In terms of price, just in April, Tesla lowered its offer for FSD(Full-Self Driving, referred to as "FSD") twice to attract users. Just a week ago, Tesla announced that the price of its FSD system package was lowered by about one-third from $12,000 to $8,000, just after lowering the price of models in the Chinese and American markets. Prior to this, on April 13th, Tesla announced that the monthly subscription price of FSD (supervised) had dropped from $199 to $99, and the subscription price was directly "halved".

　　Musk predicts that Tesla’s FSD test mileage needs to reach 6 billion miles to meet the requirements of global regulators. The data released by Tesla on April 6 shows that the actual test mileage of FSD is 1 billion miles. At present, Tesla FSD has been upgraded to the end-to-end version of V12.3, no longer relying on traditional rule codes, but relying entirely on neural networks and data drivers.

　　According to industry experts, if Tesla FSD lands in China, the data collection, model training and computing center will be regarded as the key. () The research report points out that if FSD is popularized in China, the whole set of closed-loop data needs to be made in China, and preparations should be made in terms of data collection and model training, and whether the BEV sensing scheme can be well adapted locally should be considered. In China, FSD mapping may need to cooperate with China manufacturers, and Tesla needs to set up a local computing center and a local algorithm adaptation team.

　　Us regulators release Tesla Autopilot survey summary report

　　The National Highway Traffic Safety Administration (NHTSA) revealed last Friday that it has started a new investigation into Tesla. The survey covers Model Y, X, S, 3 and Cybertruck vehicles equipped with Autopilot, which were produced in the United States from 2012 to 2024.

　　At the same time, NHTSA has launched an investigation into Tesla’s Autopilot recall in December last year. The agency found that the Autopilot autopilot system could not fully ensure the driver to concentrate on the driving task, and it would lead to the driver’s overconfidence in the function of the system. According to the report, these factors led to foreseeable misuse and avoidable accidents, of which at least 13 accidents involved one or more deaths.

　　NHTSA concluded that there was a "critical safety gap" between the driver’s ability expectation of Tesla Autopilot system and the real ability of the system, which led to a series of avoidable accidents. Tesla conducted a recall of 2 million American Tesla vehicles in December last year, and improved the driver monitoring system of these vehicles through software upgrades.

　　Tesla’s share price closed down 1.11% last Friday, with a cumulative decline of more than 30% this year. Tesla’s previously released financial report for the first quarter of fiscal year 2024 showed that the revenue in the quarter fell by nearly 9% year-on-year, the decline in revenue was the highest in 12 years, and the net profit dropped by 55% year-on-year. The key indicators of the financial report were all lower than expected.

　　According to another report, US Securities and Exchange Commission (SEC) documents show that Drew Baglino, a former senior vice president of Tesla who announced his resignation earlier this month, sold about 1.14 million shares of the company, with a total value of about 181.5 million US dollars. According to the document, Baglino also reduced its holdings of Tesla shares twice this year, with a total value of about 4 million US dollars.

Special feature of 1905 film network Six days after its release, The Four Kings of Di Renjie in the same period earned 1.447 billion yuan and 409 million yuan respectively, with a gap of more than three times.

Box Office Comparison between The Richest Man in Xihong City and Di Renjie (Source: Taobao Film Professional Edition)

But before the release, the data of the two films were not the same.

As of July 18th, The Four Kings had 37,000 first-day screenings, while the first-day screenings of The Richest Man in Xihong City were only 18,000.

At that time, Tsui Hark’s third Di Renjie series was far ahead of Mahua FunAge’s fourth, whether it was momentum or pre-sale. The latter’s online pre-sale is even just a fraction of the former.

But the data changed on the day of the release. On the day of the release, "Four Kings" opened 115,000 screenings, with a box office of over 100 million. However, "The Richest Man in Xihong City" won twice the box office income of Tsui Hark’s costume fantasy blockbuster with an extra gap of 30,000 games.

Comparison of box office and film arrangement of two films on the first day of release (July 27)

On the morning of 28th, the douban score of "Xihong City" also surpassed "Di Renjie" by 0.1.

We asked a publicist of "The Richest Man in Xihong City", and she revealed that the online pre-sale of the film was really late. However, based on the huge audience, it is not surprising to achieve the current box office results.

　

"Our distribution team went to a city like Qiqihar and found that the cinema was full in the afternoon." She said.

Xiao Dianjun learned that in the pre-heating stage of publicity, Alibaba Pictures, one of the producers of "The Richest Man in Xihong City", built a ticketing platform fan community, "Xihong City Community".

Users can join the Xihong community and become Xihong citizens by clicking "Want to See". In the community, through game interaction, film association and ticket purchase guidance are carried out.

Relevant people told Xiao Dianjun,At present, the number of "citizens" in this community has reached 1.91 million: "At different stages, it has brought many benefits to let users interact and spread."

　

Compared with "Xihong City", the marketing efforts of "Di Renjie" are slightly lacking. At the beginning of Huayi’s "Former 3" tasted the sweetness through the marketing of short video platforms such as Tik Tok, as its film, "Four Kings" inevitably used these platforms to gather young people.

Comparison of official account data of two films in Tik Tok

"As a channel platform, Tik Tok is actually similar to Weibo and WeChat a few years ago. As a social platform, it can directly deliver some marketing actions to customers, and it is an unavoidable channel platform in this year’s project implementation." A propaganda of "Four Kings" tells us that he also mentioned that the advantage of such a platform is that there is no middleman to earn the difference.

　

Because it has been five years since the last Di Renjie was released, the promotion of Four Kings pays special attention to the marketing of young people.

In addition to the behind-the-scenes tidbits, the short videos of Four Kings on Tik Tok include "CP" of Mark Chao and Kenny Lin, "Shui Yue Makeup" created by many masters and Carina Lau’s "This is Jison" and other funny clips.

Various short videos of "Four Kings" launched on Tik Tok.

Tsui Hark even accepted an interview with the barrage website. At present, the video has been played 261,000 times and there are 3,000 barrage.

The propagandist said that it is necessary for the film’s marketing to sink: "Because of the theme,’ sinking’ lacks natural advantages. However, there are also some relaxed elements in Di Renjie, including some behind-the-scenes content, which can actually be handed over to users through short-sightedness and stimulate the desire to watch movies. "

Although it uses the same marketing platform as Previous 3, it is obvious that the influence of Four Kings on these short video platforms is not as strong as that of Previous 3.

During the film "Ex-3" was released, its three theme songs kept a very high volume in Tik Tok, and many people even used these three pieces of music as their short video background sounds to shoot their crying scenes after coming out of the cinema.

　

The related vibrato videos of "Previous 3" often get millions of praises.

This emotional attachment to the past is very easy to infect more people who watch short videos, which indirectly leads to more people entering the cinema.

　

In 1960s, david ogilvy, an American advertising master, put forward the advertising 3B principle — — Beauty (beauty), Baby (baby) and animal (Beast), that is, advertising can attract consumers’ attention if it meets one of the 3B principles, thus stimulating purchases.

　

Now, half a century later, the current audience’s preference for video content has not got rid of this principle. According to the propagandists of "Four Kings", in film marketing, Tik Tok users prefer to create videos specially made for Tik Tok, rather than Tik Tok packaging of materials.

On the other hand, "The Richest Man in Xihong City" carried out a series of related publicity with the football elements in the film as the selling point, and what helped Mahua FunAge was that after the film just caught up with the Russian World Cup, the topic of football remained unresolved.

Shen Teng, the founder, not only explained the World Cup, but also appeared in fashion magazines as a football player.

　

However, the release of an "AV Milan" material attracted many fans’ antipathy to the film and made the film almost hot.

Later, the concepts promoted by The Richest Man in Xihong City became "funny" and "how to spend 1 billion RMB".

　

A person familiar with the matter told Xiao Dianjun that Calories, which was sung by Rocket Girl, was the cooperation of Shen Teng in the early stage of Creation 101. In the eyes of the marketing staff interviewed, this cooperation is indeed one of the biggest marketing of the film.

However, this staff member told us that the promotion song "Under the Rainbow" sung by Zhao Lei has a better effect and has attracted more attention in various communities.

　

On the attention of WeChat, "Xihong City" is indeed ahead of "Di Renjie".

According to the data of the ticketing platform, after 6 days of release, the WeChat index of "The Richest Man in Xihong City" rose instead of falling, reaching 30.7%; The "Four Kings" has now dropped to 4.9%.

In WeChat official account, there are 13,000 articles about "The Richest Man in Xihong City", with a total reading of more than 8 million; There are 11,000 "Four Heavenly Kings", and the total reading is half of the former.

　

Looking through these articles by WeChat official account, we find that the key words of The Richest Man in Xihong City include "Spend money hard", "Don’t be profound" and "Poverty limits imagination", and the main theme is the simplest and rudest "Rich", which is funny.

From pre-sale to marketing, Di Renjie has not fallen behind, but the angle and means of exerting its strength remain to be discussed. In contrast, on the other hand, "The Richest Man in Xihong City" seems to be "no move to win."

The critics and the general audience have been arguing about which is the higher quality of the two films. Judging from the box office figures and ratings of various platforms, Di Renjie is an unavoidable "complete failure" for Xihong City.

I have to say that the victory of "The Richest Man in Xihong City" lies in fully catering to the expectations and preferences of the current audience.

In this regard, we don’t know whether it is "happiness" or "worry".

Huasheng Online March 15 (Reporter Yu Qian) What should I do if there is something wrong with my home appliances? Searching online for brand customer service telephone repair has become the first choice of many consumers. However, seemingly regular 400 telephones are not necessarily official after-sales hotlines, and there are many hidden dangers in on-site maintenance. Recently, a survey conducted by reporters in the columns of "Xiangwen Complaints Through Train" and "Consumer Complaints" found that the threshold for handling "400" calls was low, and the online search shanzhai hotline was given priority recommendation by search engines.

Search the brand "400" phone online.Encounter a "cottage"repair

At the beginning of March, Ms. Liao, a citizen of Changsha, found that the boiling water temperature of Baxi brand wall-hung boiler, which had been used at home for more than ten years, couldn’t get up, so she asked her husband to search the after-sales maintenance hotline of Baxi wall-hung boiler through the Internet and got a number of 4009918883. After dialing, the other party claimed to be the customer service of the manufacturer, so she could leave her address and arrange a maintenance master to come to the door.

A maintenance master who claimed to be sent by the manufacturer came to the door as scheduled. After a simple inspection, the maintenance master said that the controller was broken and needed to be replaced. The motherboard had some problems and needed to be repaired, which cost a total of 1,600 yuan. After some bargaining, the master finally agreed to charge 1000 yuan.

"The master fixed it quickly. After collecting money and adding WeChat, he left without leaving any documents, which was very casual." Ms. Liao recalled that the more she thought about it, the more wrong she was, and she found the official after-sales hotline 4006688700 from the official website of Baxi brand again. When she asked, she learned that she had encountered cottage maintenance, and the official maintenance quotation was actually half cheaper.

Ms. Liao spits out, "We just believe in online search too much. By default, as long as the phone starts with 400, it is formal."

Inconsistent official identification before and after customer service is false after-sales

On March 14th, according to the telephone provided by Ms. Liao, the reporter contacted the maintenance master and asked if it was "after-sales service of Baxi manufacturer". The master said that he was "from Baxi maintenance center".

As a consumer, the reporter dialed the telephone number 4009918883 that Ms. Liao’s husband called for repair at that time. Without telling the brand of home appliances, the wiring customer service claimed to be "a paid maintenance line, and any brand can be repaired, and orders can be received nationwide". After simply asking about the brand of home appliances, the fault situation and the location, the customer service also called itself the "eight-up special hotline" and told the reporter that there would be a master contact later, and the door-to-door fee would be 40 yuan, and the maintenance and replacement of accessories would be counted separately.

Subsequently, the reporter contacted Manager Pang, the after-sales person in charge in Hunan Province, through the after-sales service hotline 4006688700 displayed on Baxi official website. After listening to the reporter’s description, Manager Pang said that the reporter should have encountered a fake after-sales service of Baxi. "The official after-sales hotline is only 4006688700. After the customer reports for repair, he will receive a feedback message, and then the master with authorized service qualification will come to the door. The specific maintenance fee is charged according to the after-sales manual provided by the manufacturer, and formal documents will be issued after the repair."

"I have received many customers’ reports that the level of after-sales personnel in the cottage is uneven, and sometimes it is still minor and overhauled, but we can’t stop it." Manager Pang said helplessly.

The cottage is recommended first after sale.400 telephoneLow threshold for handling

When the reporter searched for the keyword "brand+after-sales" through the mobile phone, he found that many cottage maintenance information ranked in front of the official after-sales information, and was also marked with "national unified customer service hotline" and "headquarters maintenance". Many consumers said that it was difficult to identify if they did not browse carefully.

Why is the false after-sales hotline recommended first? An advertising agent of a search engine told reporters that the display order may be related to advertising bidding ranking and keyword matching, and the information with high price and high fit will be given priority.

Handling the "400" hotline is also very simple. The reporter’s investigation found that on a shopping platform, as long as you provide the business license, legal person ID card and official seal, you can do it with money. The minimum package is one year in 260 yuan, and the annual fee can be fully deducted. 114 can’t find the real information of the company.

Hunan Consumer Protection Committee reminds: Don’t trust the so-called "official maintenance" of online search.

Some insiders said that in recent years, some home appliance enterprises have paid more attention to marketing than after-sales. With the increase of operating costs, the number of regular home appliance repair stores has been decreasing, which has made some cottage repairs have living space, taking advantage of the characteristics of large market demand, low operating threshold, asymmetric information and high difficulty in illegal accountability, and fooling consumers into paying the bill.

In order to prevent consumers from encountering the trap of "cottage" home appliance maintenance, Hunan Consumer Protection Committee reminds consumers that when choosing maintenance services, whether within the warranty period or not, they should first choose the official after-sales service outlets of the purchased brands, and don’t trust the so-called "official maintenance" searched by the Internet; When applying for repair, we should try our best to explain the fault situation so that the door-to-door personnel can take the spare parts and dispose of them in time; After confirming the identity of maintenance personnel, it is necessary to know in detail the charging standards of maintenance projects and whether formal invoices can be issued. If necessary, you can seek technical support from official customer service and understand the official price charging standards; Consumers should collect relevant evidence for the behavior of raising the price or adding maintenance items in the middle of maintenance service, which can be reflected to the official website of the brand, or through relevant government departments and consumer associations to defend their rights.

With the extensive and in-depth application of information technology, especially the continuous development of e-government, the website of party and government organs has become increasingly prominent. It has become an important window to publicize the party’s line, principles and policies and open government information, and an important platform for party and government organs at all levels to perform social management and public service functions, do things for the people, understand social conditions and public opinion, and accept supervision by the masses. The Fourth Plenary Session of the 18th CPC Central Committee put forward that "network behavior should be regulated according to law", which requires us to institutionalize and standardize the management of online names of party and government organs according to law, so as to ensure that the websites of party and government organs are "be worthy of the name, standardized names, safe operation and healthy development", thus ensuring the safety of websites of party and government organs and institutions.

First, the connotation of website security of party and government organs and institutions

General Secretary of the Supreme Leader pointed out that there is no national security without network security, and it is necessary to strengthen the management of new technologies and applications in the network to ensure that the Internet can be managed and controlled. Internet is a double-edged sword, well used, it is the treasure house of Alibaba; It doesn’t work well. It’s Pandora’s box. The website security of party and government organs and institutions includes three aspects: identity security, integrity security and information security.

One is identity security. In the real world, party and government organs and institutions have their own office space, which can only be listed, publicized and provided with services for the public after being examined and approved by the establishment departments at all levels in China, so its identity is well known to the public and is safe and reliable. However, in the virtual space of the Internet, in recent years, criminals posing as party and government organs and institutions have frequently set up fake websites, which has had a bad influence on the authoritative image of party and government organs and institutions and also caused losses to the public. Therefore, the identity security of party and government organs and institutions on the Internet needs to be guaranteed, so that the public can clearly identify them and will not be deceived by fake websites.

The second is integrity and safety. With the development of the Internet, the public can obtain government information and communicate with the government online in real time. The government can also contact the public synchronously, instantly, trans-regionally and trans-temporally through the Internet, and feedback the public’s demands for the government at the first time, thus effectively conserving, maintaining and cultivating the people’s trust in the government. However, due to various reasons, a large number of news in the name of the government have been published and reprinted on the Internet, and the public can’t tell whether these news are true or false. Some rumors confuse the public and even cause group incidents, which is not only detrimental to the long-term stability of society, but also directly damages the integrity and authority of the government.

The third is information security. At present, the websites of party and government organs and institutions have become an important platform for policy release and interaction between the government and the people, and at the same time, they have also become the carrier of public personal information because of the public’s online business. The Internet is logically divided into three layers. The first layer is the basic layer, including bandwidth, IDC computer room and mobile interconnected base stations. The second layer is the basic resource layer, including domain name, IP and so on; The third layer is the application layer, including mail, website, application system and so on. Among them, the second layer represented by domain name is the key to information security risks. If the Internet is likened to a highway, the second floor is equivalent to signs and cameras on the highway. If the highway of China’s Internet is guided by English signs and monitored by foreign cameras, then security can certainly not be guaranteed. Therefore, if Chinese government websites use commercial domain names, each parsing data will be reflected in the root server of this domain name, which will be mastered by foreign countries. Once the website has security risks, the public’s personal information will not be guaranteed, which directly threatens China’s network information security.

In a word, it is very important for party and government organs and institutions to ensure the safety of their websites. This requires that the identity of the websites of party and government organs and institutions can be confirmed, the voice can be distinguished, and the information can be guaranteed.

Second, how to ensure the website security of party and government organs and institutions

Online name management refers to the four-in-one comprehensive management with the use of online names and online identity identification of party and government organs and institutions as the core and domain name registration, website audit, website labeling and annual report as the main contents. Through the monitoring, retrieval, identification and protection of the online identity of institutions, it is widely used in various platforms such as Weibo, WeChat and browser, and finally makes the online identity clearer, the network environment clearer and the online business more secure.

(1) Domain name registration

According to the Interim Measures for the Administration of Online Names of Party and Government Organs, Institutions and Social Organizations (hereinafter referred to as Document No.6) jointly issued by the Central Committee and the Ministry of Industry and Information Technology, party and government organs and institutions must register and use standardized Chinese domain names for ".government affairs" or ".public welfare". These two Chinese domain names are technically unique, highly recognizable in form and strictly managed by the organization’s establishment department, which makes them qualified as "online identity cards" for organizations, and also makes Chinese domain names the premise and core of online name management.

(2) Website audit and website labeling

In May 2014, the Central Network Information Office issued the Notice on Strengthening the Website Safety Management of Party and Government Organs (hereinafter referred to as Circular No.1), which clearly required the organization department to be responsible for the website start-up audit and qualification review of party and government organs, and to design and formulate the usage norms of website logos of party and government organs.

Website labeling refers to placing a unified website logo in a prominent position at the bottom of the website after the websites of party and government organs and institutions are approved by the organization department. Clicking this logo will display the basic information of the company and the online name, etc., so as to facilitate the public to distinguish the authenticity of the website.

(3) Annual report

According to Circular No.6 and the Notice on Doing a Good Job in Auditing, Qualification Review and Website Logo Management of Party and Government Organs’ Websites (hereinafter referred to as Circular No.69) jointly issued by the Central Editorial Office and the Central Network Information Office, online names and website logos are subject to a regular reporting system, and website owners should regularly report online changes in their qualifications, the use of online names and website logos to the organization establishment department.

Third, the significance and necessity of online name management.

(1) Why is the organization department responsible for the management of online names?

The organization establishment department holds the most accurate information of organization identity and name, and is managed by the organization establishment department, which can effectively ensure the "be worthy of the name and standardized name" of party and government organs and institutions on the Internet. Therefore, as early as 2008, the Ministry of Industry and Information Technology clearly stipulated that Chinese domain names for government affairs and public welfare should be managed by the organization department. In 2014, in the No.1 document issued by the Central Network Information Office, it was further stipulated that the organization preparation department was responsible for the audit and qualification review of the website of the party and government organs, and designed and formulated the usage norms of the website logo of the party and government organs.

(2) Why should we register and use standardized Chinese domain names?

Chinese domain names for government affairs and public welfare conform to the language and cultural habits of Chinese people, and can clearly reflect the name and functions of institutions, similar to the "online ID card" of institutions. For example, the Chinese domain name compiled by the central government is "Central Compilation. Government Affairs". Compared with its English domain name "scopsr.gov.cn", the Chinese domain name is clear at a glance, which not only embodies the authoritative identity of the organization, but also facilitates public recognition and memory, and is the basic guarantee for netizens to surf the Internet safely and do things with confidence.

Fourth, the significance of establishing an online ID card authentication and protection application system with Chinese domain names as the core.

The first is to maintain authority. It is an important means to maintain their authoritative status in cyberspace to put on "anti-counterfeiting clothes" for institutions by standardizing online names and hanging website logos. The second is to make it safer to do things online. Marking the identity information of the organization on the Internet makes it easy for netizens to distinguish the true and false websites of the organization, which can improve the efficiency and facilitate the work on the Internet. The third is to ensure national information security. Party and government organs and institutions are the core political resources in China, and their information security on the Internet is particularly important. Strengthening the authentication and protection of its online identity can effectively guarantee the security of the country’s core information. The fourth is to make the organization management more scientific. Through website logo management, we can fully understand the online performance of institutions and provide scientific reference for the performance evaluation and management of institutions.

We maintain the seriousness and authority of the websites of party and government organs and institutions, protect the safety of the websites of party and government organs and institutions, and establish a green channel for the public to visit the websites of government departments and public welfare institutions quickly and accurately, so as to promote the popularization of Internet application and the development of government affairs openness and e-government in China.

　　Eight Nankai students are ordinary members of Qian Qian’s 10 million new college students in 2017. Among the eight people, some are the children of Xinjiang’s anti-terrorism martyrs, some are descendants of veterans who fought against US aggression and aided Korea, both urban youth and peasant children. Today, they have all grown up obviously: Kazakh boy Ashar, "challenged" to be the platoon leader of special warfare players for six years and completed the 3000-meter run in 11 minutes and 30 seconds; Dai Rui, a female soldier, changed from a "cute girl" on campus to a "female man" in a military camp. In order to cultivate a tall and straight military posture, she put paper on her knees and bricks on her head; Dong Xudong, the champion of the local college entrance examination, went from "Xueba" in the university to "Young Eagle" in the new training.

　　Key point two: the continuous development of national defense mobilization level will improve the ability of science and technology to participate in the war and support the front.

　　National defense mobilization is a bridge to transform national defense potential into national defense strength and an important content of national defense construction. The effectiveness of national defense mobilization construction is related to national security and development, and to the victory or defeat of future wars.

　　In 2017, with the adjustment of the whole army to form 84 military units, including services and arms units and provincial military region systems, various reform measures of the national defense mobilization system gradually landed and achieved new breakthroughs.

　　Planning and design are clearer. Combined with the formulation of the "Thirteenth Five-Year Plan" for national defense mobilization construction, the long-term tasks of national defense mobilization in 2025 and the indicators of core mobilization ability are demonstrated and put forward. Various strategic directions, mobilization fields and provinces (autonomous regions and municipalities) have also formulated various planning plans at different levels.

　　Accelerate the transformation of the construction model. Vigorously promote the transformation of national defense mobilization from quantitative scale to quality and efficiency, from ensuring army operations to ensuring joint operations of services and arms, from corresponding construction to complementary construction, and from extensive mobilization to precise mobilization.

　　The field of mobilization continues to expand. Adhere to information-oriented, increase preparations for supporting and ensuring the mobilization of services and arms, strengthen the construction of new mobilization forces such as information support, electromagnetic spectrum, meteorology and hydrology, mapping and navigation, medical rescue, and maintenance of high-tech equipment, actively explore expansion in various fields, improve the ability of science and technology to participate in wars and support the front, and lead national defense mobilization to a higher level.

　　At the same time, in order to meet the requirements of the reform of the military leadership and command system, the National Defense Mobilization Department of the Military Commission has guided Jiangsu, Guangdong, Fujian, Hunan and other provinces and military regions to carry out relevant pilot work, and made useful explorations in building a wartime mobilization organization and command mechanism, a mobilization demand reporting and docking mechanism, and establishing and improving a mobilization preparation inspection and evaluation system.

　　Focus 3: There are many preferential policies for resettlement of retired soldiers and entrepreneurship and employment.

　　The State Council and the Central Military Commission promulgated the Regulations on Resettlement of Retired Soldiers in October 2011. The Regulations specify a series of preferential policies for resettlement and entrepreneurship of retired soldiers.

　　Eligible retired soldiers can be arranged by the government. Non-commissioned officers have served in active service for 12 years; During the period of active service, he usually won a prize above Class II or a prize above Class III in wartime; Disability due to war is rated as level 5 to level 8 disability; Children of martyrs will be arranged by the people’s government.

　　【Extended reading】

　　Military service registration is a mandatory obligation.

　　In fact, many people don’t know what military service registration is, and think that I don’t have the will to be a soldier, so I don’t need to go to military service registration. However, this is not the case. Article 13 of China’s Military Service Law stipulates that the state practices the military service registration system. Every year before December 31st, male citizens who have reached the age of eighteen shall go to military service registration before June 30th of that year according to the arrangement of the military service organs of counties, autonomous counties, cities and municipal districts.

　　According to the relevant regulations, military service registration is the registration management for citizens who meet the military service age, and it is a compulsory obligation of the state. Male citizens of the appropriate age who do not intend to join the army for the time being must also undergo military service registration and verification. Military service registration, mainly to prepare for the annual conscription work. That is to say, it is not necessary to join the army after military service registration.

　　Avoiding registration is responsible for affecting credit reporting.

　　Evading or rejecting citizens of military service registration will not only affect their normal participation in the army, but will also be subject to administrative punishment. According to the provisions of the Military Service Law, if a citizen who applies for enlistment refuses, evades the solicitation and refuses to make corrections, he shall not be employed as a civil servant or a staff member managed according to the Civil Service Law, and shall not go abroad (territory) or pursue further studies within two years. If the refusal to perform relevant obligations in wartime constitutes a crime, criminal responsibility shall be investigated according to law. (Feng Renqing)

　　Sanyuanli vegetable market in Chaoyang District is neat and standardized, clean and hygienic, with complete products. Because it is close to the embassy district, it also attracts many foreigners to buy it. Reporter Deng Wei photo

　　Reporter Ma Jing

　　Just after 9: 00 a.m., Sanyuanli vegetable market became lively. Chefs from western restaurants came to buy lunch ingredients, young mothers picked imported fruits, and takeaway brothers walked quickly through busy delivery. Delicious vegetables, colorful fruits, seafood from all over the world, and strange spices … … Although this vegetable market with an area of only 1,560 square meters is small, it is full of all kinds of delicious food from all over the world.

　　In the vegetable market, a long and narrow passage runs through the north and south, with 140 merchants on both sides. In a booth of only a few square meters, merchants set up a ladder with a simple frame to place dishes, and the layered vegetables will be surrounded by vegetable sellers, who can only drill in and out from the corner of the ladder.

　　For 59-year-old Li Xueling, loading goods is a manual job, but she enjoys it. Before dawn, her whole family drove to major wholesale markets to select fresh "sharp goods". After being transported back to the vegetable market, they had to choose dirty leaves, wrap them in plastic wrap, and put them on the stalls after some initial processing. "The morning is the busiest and most chaotic time, but the market is neat as soon as it opens." Li Xueling said.

　　"Elder sister, give me a small box of sweet beans and a catty of tomatoes." Just opened, Ms. Sun, an old customer, appeared in front of the booth in Li Xueling as usual. The price of two vegetables of nearly 100 yuan did not surprise Ms. Sun. After skillfully scanning the code to pay, she picked up the bag and walked to the fruit stand.

　　What attracts Ms. Sun is that there are always unexpected gains here. A kilo of organic tomatoes in 20 yuan, Japanese pumpkins that are often sold out of stock, Brussels sprouts that look like mini cabbages, and delicious flowers with high value … … The small vegetable market is an eye-opener and makes people enjoy the beauty of food.

　　"Who would have thought 30 years ago that there are so many kinds of vegetables now?" Li Xueling remembered that she and her husband came to Beijing from their hometown in Baoding, and each of them joined the army of selling vegetables with a flatbed. At the beginning, all the stalls were the same road dishes, with only five or six varieties. At that time, she didn’t expect that such a "online celebrity" vegetable market could be built on the grassland that she passed every day when she went home.

　　In 1992, before and after the country completely abolished the policy of residents buying pork by ticket, vegetable greenhouses were built in Sanyuanli vegetable market, and roadside vendors pushed carts into the market to set up stalls. Since then, this old vegetable market has undergone many upgrades and hardware upgrades, and it has also evolved into an international vegetable market full of emotional appeal.

　　If the opening is the right time, internationalization is the right place. Because of its proximity to the embassy district, Sanyuanli vegetable market has attracted customers from all over the world, and various demands have also made merchants smell business opportunities. This vegetable market, which takes two or three minutes to walk quickly, has gradually become a "fresh United Nations".

　　Yesterday evening, Liu Rong, a white-collar worker who just finished working overtime, walked into Sanyuanli vegetable market and went straight to a cheese shop, with black lemon cheese and colorful red sauce cheese … … Liu Rong, who just learned to cook western food, was dazzled.

　　"I have no cheese you can’t find." Shop owner Wen Guochen is full of confidence. Twenty-two years ago, he was a vegetable merchant in the market. Because many foreigners who came to buy food could not find their own cheese, Wen Guochen decided to change careers. He asked the import agent to collect all kinds of cheese and spices to satisfy the stomachs of foreign customers. In recent years, more and more Chinese began to patronize his small shop, and the business was getting better and better.

　　Just after seeing off the customers, a fashionable food anchor walked into the store, aimed the camera at the cheese in the freezer, and the screen of the mobile phone flashed with questions from fans. For such a scene, Wen Guochen has long been accustomed to it. In recent years, artists have come to hold exhibitions, writers have come to hold new book conferences, and economists have come to hold small classes in economics. The unique "online celebrity" temperament makes this vegetable market bring people endless imagination.

　　Li Xueling felt that in the past two years, the number of passengers in the vegetable market has decreased, but the micro-shops in mobile phones have become busier. "When someone visited once, they added WeChat. When it is inconvenient to come, they will place an order online." Like Li Xueling, merchants have been operating mobile phone markets. The take-away and flash delivery staff who shuttle through the market have also become a unique landscape.
