　　[PConline evaluation] "Keeping pace with the times" is like the blood flowing in the body of a technology manufacturer. Without blood, you can’t survive; Without hematopoiesis, there is no vitality. And "keeping pace with the times" has different concrete appearances in different industries and different types of manufacturers. For example, in the notebook industry we are going to talk about next, "keeping pace with the times" means using the latest hardware and adopting a design language that fits the times and approaches consumers.

　　From the hardware point of view, the latest hardware is nothing more than Intel’s eight-generation (thin notebook)/nine-generation (game notebook) processors and NVIDIA’s MX (thin notebook) /RTX (game notebook) graphics cards. As a leader in the notebook industry, what kind of new hardware is connected in series and what kind of design is used to make Lenovo’s products stand out in the fierce competition in the market? This time,

　　Intimate design and accurate positioning of users

　　Just as black and white is an eternal classic, simplicity is a design that never falls behind. However, simplicity does not mean monotony, and how to distinguish simplicity from monotony, Lenovo Xiaoxin Air 15 2019 is realized by small corner LOGO embellishment.

　　The front of Lenovo Xiaoxin Air 15 2019 is treated with frosting and spraying technology. On the whole, it looks strong in metal texture, and it is dry and delicate in practice.

　　On the front of Nuoda, except Lenovo Logo in the upper left corner, the notebook has no other gaudy logo, which is concise and clear, not only conforms to the design pursuit of simplicity and fashion of young people at present, but also shows the neatness and competence of business elites when taking it on business trips.

　　When it comes to the use of business elites, Lenovo Xiaoxin Air 15 2019 is equipped with many practical interfaces. Among them, from the outside to the inside, USB 3.1 interface x 2, SD card reader and small hole with "one-button recovery" function are arranged on the right side. The external USB 3.1 interface can charge mobile phones, tablets and other devices even if the computer is turned off. The notebook is cleverly transformed into a large charging treasure, and there is no need to carry multiple charging treasures on business trips, which is easy and enjoyable; The "one-button recovery" function converted from the ThinkPad blue key can also help users get out of trouble easily when they encounter intractable problems such as system crash/computer blue screen.

　　As for the left side, the power interface, HDMI display interface, USB Type-C interface and 3.5mm 2-in-1 audio interface are listed in turn. With the addition of USB Type-C interface, the diversified interface support of the computer is realized. No matter what type of data cable the mobile phone uses, there is always an interface suitable for you.

　　At the back of the rotating shaft and the bottom of the notebook, a large fence corresponds to the cooling fan of the notebook, and the heat generated when the notebook runs large software also has sufficient cooling space.

　　In addition, different from the traditional four-corner foot pads, Lenovo Xiaoxin Air 15 2019 uses 2+1 rubber foot pads at the bottom, with long and thick rubber foot pads. With the first two small foot pads, the notebook can be used stably in more scenes.

　　Thanks to the flexibility of the rotating shaft, the opening and closing angle of Lenovo Xiaoxin Air 15 2019 model can reach 180. It is also very convenient to play drama on the sofa/bed in leisure time and discuss ideas with others at work.

　　The narrow bezel design that keeps pace with the times generally stays at a width of 7.5mm in the market, while Lenovo Xiaoxin Air 15 2019 has achieved a width of 4.25mm, which makes the notebook screen account for as much as 85.3%. The 15.6-inch notebook looks only the size of the traditional 14-inch notebook. When users are working, their horizons are wider and their mood is naturally brighter, and they can also feel greater vision when watching movies.

　　Due to the integration of the camera and microphone required for video, the forehead of Lenovo Xiaoxin Air 15 2019 is not as narrow as the borders on both sides, but it is still much narrower than the ordinary models on the market. On this narrow forehead, Lenovo skillfully added a physical peep-proof switch to the camera, turned it off to the left and turned it on to the right. In an era when privacy is increasingly valued, sometimes an excellent design language is a small and intimate design that meets the needs of the times.

　　Now that we talk about privacy protection, fingerprint recognition is indispensable for a light notebook that keeps pace with the times. In the lower right corner of the keyboard of Lenovo Xiaoxin Air 15 2019, the fingerprint recognition function is added to Lenovo Xiaoxin Air 15 2019. This pressed fingerprint key can be used as a power-on key, and it can be unlocked to enter the system when it is dormant, thus avoiding the embarrassment of inputting passwords in front of many people and effectively protecting personal privacy.

　　Maybe you will ask, with this button, what is the function of the power button in the upper right corner? Just as the "one-button recovery" function exists, a backup scheme is also needed for the safety of business use. The existence of the power key is not only the first entrance when fingerprint identification is not set, but also the second entrance when fingerprint identification fails.

　　In order to get a better feel, many users like an external mechanical keyboard. Going on a business trip means saying goodbye to the mechanical keyboard, but using Lenovo Xiaoxin Air 15 2019 does not mean saying goodbye to a good feel.

　　Lenovo Xiaoxin Air 15 2019 keyboard adopts an isolated chocolate keyboard, and each key exists independently, with a distance of 19.05mm, which is not easy to touch by mistake; The key stroke is 1.3mm, and the quick tapping response is quick; Coupled with the matte paint on the surface of the keycap, although the feel is not as good as that of the mechanical keyboard, it is definitely not bad for business trips.

　　In addition, it is not difficult to use the backlight at night by calling up the backlight through FN+ space bar. And the digital keyboard area that makes full use of space will greatly improve the office efficiency for friends who have to deal with numbers every day.

　　In the touchpad part, Lenovo Xiaoxin Air 15 2019 adopts an integrated glass touchpad solution. The area looks small, but it is very sensitive and smooth in actual operation. It can complete accurate operation only by clicking and gesturing, and it is not a big problem without a mouse in daily office.

　　Surrounding dolby pro logic with 15.6-inch ultra-narrow bezel and high color gamut full HD IPS full screen not only provides users with excellent audio and video experience visually but also audibly.

　　In terms of thickness and weight, Lenovo Xiaoxin Air 15 2019 is made of aluminum alloy metal, which provides sufficient strength guarantee for the fuselage, and also makes the whole notebook lighter. The thinnest part is 16.9mm, and the 15.6-inch fuselage with power adapter is only 2.3kg (1.76kg for the fuselage), so it is relatively light to carry on business trips.

　　Excellent configuration to enhance user experience On the screen side, Xiaoxin Air15 2019 adopts the popular "high color gamut IPS screen", which has a high color gamut coverage of 72%NTSC, and the screen resolution is 1920×1080. The surface layer is treated with anti-glare atomization, and with the high brightness of 300 nits, it also has a good impression under strong light.

　　On the processor side, Lenovo Xiaoxin Air 15 2019 is an eight-generation Core i7-8565U equipped with Intel’s latest Whiskey Lake architecture. This processor has been enhanced, and its performance is at least 10% higher than that of the i7-8550U introduced earlier, with a main frequency of 1.8GHz, a turbo frequency of 4.6GHz, 4 cores and 8 threads, a third-level cache of 8 MB, and a TDP of 15W.

　　With a stronger eight-generation Core i7-8565U, Lenovo Xiaoxin Air 15 2019 also enables multi-mode support. Through FN+Q, users can switch between beast, mute and balanced modes at will.

　　When the external power supply is inconvenient for business trip, use the "silent" mode with longer battery life; Leisure and entertainment want to play games such as League of Legends to start the "beast"; Multi-mode selection also makes it better adapt to more usage scenarios.

Silent mode

Beast mode

　　Then, under different modes, what is the performance difference of Lenovo Xiaoxin Air 15 2019? We tested its lowest performance "silent" mode and the strongest performance "beast" mode through CINEBENCH R15. The results are shown in the figure, and the final results of the "silent" mode are: multi-core 542cb and single-core 160cb；; Final results of "Beast" mode: multi-core 694cb, single-core 171cb.

　　Judging from the score, the silent mode is quite different from the Beast mode, but don’t underestimate the performance of the silent mode, which is only a little lower than i7-8550U (single core 166cb, multi-core 561cb), which also means that in the silent mode, any browser can be opened more, office software can be used, or PS retouching, video editing and simple rendering can be done.

　　As for the "Beast" mode, the single-core performance basically exceeds that of the previous generation i7-7700HQ standard voltage. In other words, this processor has more than enough computing power to deal with some mainstream online games.

　　Since there is no problem with the computing power of the processor, the only other factor that may hinder the notebook from playing is the core temperature. We use AIDA for this part? 64 Carry out CPU copying test on Lenovo Xiaoxin Air 15 2019. Under the condition of 100% high load, we can see that the core temperature of i7-8565U fluctuates regularly between 70℃ and 90℃, and the whole process processor runs stably without sudden frequency drop. It is not easy to perform stably at high temperature. This achievement is not only due to the low power consumption of Intel processor, but also thanks to the design skill of Lenovo’s double fans, double copper pipes and die cooling of the whole machine.

　　During the copying process, we tested Lenovo Xiaoxin Air 15 2019 with infrared thermometer. Under the condition of room temperature of 26.1℃, the high temperature area of the machine is mainly concentrated in the heat dissipation port at the rotating shaft, with the highest temperature of 47.3℃. Only by touching that position with your hands can you feel the temperature.

　　As for the graphics card, NVIDIA MX250 has a core frequency of 1519MHz and a memory frequency of 1752MHz. It is full of blood without castration, and its performance is improved by 5% ~ 10% compared with the "full blood version" MX150, which can meet the needs of ordinary 3D online games and barely getting started eating chicken. In addition, the editing speed of general pictures and videos such as Photoshop, Illustrator, Lightroom and Premiere will be faster.

　　In the hard disk part, Lenovo Xiaoxin Air 15 2019 has a built-in 1T PCIe SSD. In the test of CrystalDiskMark, the sequential reading and writing speed of 1G file is as high as 3453MB/s and 2107MB/s, and the random reading and writing performance of 4K is 37.35MB/s and 77.78mb/s. To be honest, it is quite unexpected that the sequential reading and writing can reach such a high speed. This side reflects that Lenovo uses the same amount of materials in invisible places, and uses high-standard hardware at any cost, in exchange for a smooth user experience with 5 seconds of boot and rapid software response. In terms of product scalability, according to the official product introduction, Xiaoxin Air15 2019′ s memory supports a maximum of 20G dual-channel memory expansion. The SSD also supports dual SSDs, with extra M.2242 extension bits reserved, and supports PCIe bus and NVMe protocol as well as the main hard disk bits. As a thin notebook with a thickness of only 16.9mm, its storage scalability is still worthy of recognition.

　　The battery life-related part is a highlight of Air15 2019. Compared with the previous generation of 45Wh and the current situation that the products of the same level are mostly hovering at 50-60Wh, this year’s Air15 2019 battery has jumped to a super-large capacity of 70Wh, which is a ride in the same level of light and thin books. The official announcement has the longest battery life of 19 hours. Of course, this is the theoretical time. In fact, it is closer to the scene used by users. We recommend using PC Mark8′ s Work mode battery life test. Due to the compatibility problem with the language pack of PC Mark8, it is temporarily impossible to carry out the battery life simulation test on the test machine on hand. According to the results released by netizens at present, the longest working mode can reach about 7-8 hours. This has obvious advantages over the common score of about 5 hours.

　　In addition to the large battery, Air15 2019 also supports ultra-fast charging technology, claiming that it can be used for 4 hours after charging for 1 quarter of an hour, and it can use the fragmented time to quickly "return blood" to the computer. However, the description of 65W high-power adapter reminds me of Z6 Pro’s "27W fast charging adapter" some time ago, which is funny manually.

　　Summary:

　　Even if it is implemented in notebooks, the performance of "keeping pace with the times" is different because of different product segments. Lenovo Xiaoxin Air 15 2019, based on the common elements such as large screen, all-metal, thinness and uniqueness, also strengthened the two outstanding advantages of screen quality and battery capacity, and explained to you the configuration and design language that a large-size business thinness should have. Its version of i5/8G/1T SSD/MX250 is priced at only 5499 yuan, which is still very competitive in a light and thin book of 5000 yuan. .

All-media reporter Ruan Lu Intern Lu Qun Correspondent Wang Yijun

At present, the weather is getting colder and the temperature difference between day and night is large, which is in the high incidence season of influenza.

Huang Li, deputy director of the Institute of Infectious Disease Prevention and Control of the State Center for Disease Control and Prevention, and Li Fuqiang, an expert on planned immunization, warmly reminded that to prevent seasonal high-incidence respiratory infectious diseases such as influenza, we should make preparations in advance, raise awareness of disease prevention and strengthen health protection.

What is the flu?

Influenza (hereinafter referred to as "influenza") is an acute respiratory infectious disease caused by influenza virus, which is harmful to human health. It can be divided into four types: A, B, C and D. Seasonal influenza viruses include subtype A H3N2, subtype A H1N1 (pdm09), strain B Victoria and strain B Yamagata.

According to Huang Li, the flu mainly manifests as fever, headache, general malaise and other symptoms, and the body temperature can reach 39~40 degrees Celsius. Children’s fever is usually higher than that of adults, and the symptoms may include chills, chills, aching muscles and joints all over the body, fatigue, accompanied by loss of appetite, etc., as well as sore throat, cough, nasal congestion, runny nose, retrosternal discomfort, facial flushing, conjunctival congestion and so on.

Influenza is mainly spread by droplets such as sneezing and coughing. Influenza virus survives in the air for about half an hour. It can be infected by direct or indirect contact with oral cavity, nasal cavity, eyes and other mucous membranes, and it can also be infected by touching articles infected by the virus. In crowded, closed and poorly ventilated places, influenza may also spread in the form of aerosol.

People are generally susceptible to influenza virus, and most of them are self-limited. Some patients will have complications, which can develop to severe illness or even death. The elderly over 65 years old, children under 5 years old, especially children under 2 years old, pregnant women and patients with basic diseases are high-risk groups of influenza and need special attention.

Huang Li reminded that maintaining good personal hygiene habits is an important means to prevent respiratory infectious diseases such as influenza. For example, wash your hands frequently, keep indoor ventilation, try to avoid going to crowded places, have a balanced diet, exercise, and minimize rubbing your eyes, nose and mouth when you are in public places. You should also pay attention to regular work and rest, balanced nutrition, avoid overwork, and maintain your immunity. It is best to wear a mask when you go to a medical institution for medical treatment.

"In addition, the most effective means to prevent influenza is to inject influenza vaccine, especially for key populations. Annual influenza vaccination can significantly reduce the risk of influenza and serious complications." Huang Li said.

It is recommended to vaccinate against influenza in time.

According to Li Fuqiang, according to the Technical Guide for Vaccination of Influenza Vaccine in China (2023-2024) recently issued by the China Center for Disease Control and Prevention, annual vaccination with influenza vaccine is an effective means to prevent influenza, which can effectively reduce the risk of influenza and serious complications among the vaccinators. Suggest ≥ People who are 6 months old and have no vaccination contraindications should be vaccinated against influenza, especially the following key groups are recommended to give priority to vaccination:

1 medical personnel, including clinical rescue personnel, public health personnel, health and quarantine personnel, etc.;

2. Participants and security personnel in large-scale activities;

3. Vulnerable people and employees in old-age care institutions, long-term care institutions, welfare homes and other crowd gathering places;

4. People in key places, such as kindergartens, teachers and students in primary and secondary schools, and detainees and staff in prison institutions;

Family members and caregivers of infants under 5.6 months old and pregnant women;

6. Other people at high risk of influenza, including elderly people aged 60 and above, children aged 6 months to 5 years, and patients with chronic diseases.

Usually, antibodies with protective level can be produced after 2~4 weeks of influenza vaccination, and it is best to complete the vaccination before the peak of influenza epidemic in autumn and winter. In the same influenza epidemic season, people who have completed the whole vaccination according to the vaccination procedures do not need to be vaccinated again.

Li Fuqiang introduced that influenza vaccine is a non-immunization program vaccine, and residents can be informed, voluntary and self-funded. At present, influenza vaccines used in China are mainly divided into two categories: inactivated influenza virus vaccine and live attenuated influenza virus vaccine. The influenza vaccines approved for marketing in China include trivalent inactivated vaccine (IIV3), trivalent inactivated vaccine (LAIV3) and tetravalent inactivated vaccine (IIV4), all of which can effectively prevent influenza virus infection. Residents can choose one influenza vaccine by themselves. At present, there are sufficient reserves of influenza vaccine in vaccination clinics all over the state.

Because influenza virus is easy to mutate, it is necessary to get flu vaccine every year. Like many other vaccines, influenza vaccination does not necessarily mean that you will not get the flu, but it can alleviate the symptoms after getting the flu, significantly reduce the risk of developing into a serious illness, and avoid developing into a serious illness and death.

Experts from the State Center for Disease Control and Prevention reminded that residents who care for their health can get the flu vaccine as soon as possible, especially those who have children, pregnant women, the elderly and other key personnel at home, and should take the initiative to vaccinate the whole family as soon as possible to build a family immune barrier to protect themselves and their families from the flu. You can go to the nearest community health service center (community health service station), the vaccination clinic of township hospitals and the health department of the hospital for vaccination. You can also make an online appointment through WeChat WeChat official account of Hubei Provincial Center for Disease Control and Prevention, and make an appointment in advance for the vaccination clinic and vaccination time, which is more time-saving and convenient.

How do students and parents take precautions?

The flu is coming, how can students and parents prevent it? Huang Li suggested that personal protection is the most important, and ventilation and disinfection should not be forgotten.

Students and parents need to do personal protection, wear masks, wash their hands frequently, pay attention to cough etiquette, try to avoid going to crowded places and avoid close contact with people with respiratory symptoms. If family members have respiratory symptoms, they should rest at home, observe their health, go to work and attend classes without illness, and wear masks when they are in close contact.

Children’s three meals a day need balanced nutrition, appropriately increase high-quality protein such as meat, eggs and milk, and eat more fruits rich in vitamin C. Ensure the length of children’s sleep, and adequate sleep has a positive impact on enhancing physical fitness. Primary school students should sleep 10 hours a day, junior high school students 9 hours and senior high school students 8 hours.

Always ventilate your home and keep the environment clean. Open the window for ventilation 2~3 times a day, with no less than 30 minutes each time. If it is inconvenient to open the window for ventilation, mechanical ventilation can be carried out with the help of an exhaust fan. After patients appear in the family, the surfaces of environmental objects contacted by patients can be disinfected with chlorine-containing disinfectant containing 250 mg/liter of available chlorine, or wiped with disinfectant wipes, and the surfaces of small items can be wiped with 75% alcohol.

Huang Li stressed that in addition, students and parents should be vaccinated as soon as possible. For high-risk groups such as young children who have not been vaccinated with influenza, vaccination as soon as the influenza vaccine is available can play a good preventive and protective role.

How do schools and kindergartens prevent it?

Li Fuqiang suggested that schools and kindergartens should do a good job in health monitoring, strengthen ventilation and disinfection, and build a strong immune defense line during the high-incidence season of influenza.

Schools and kindergartens should strengthen morning and afternoon inspections and full-day observation. Strengthen the registration system of absence due to illness, grasp the reasons of students’ absence, and find and report early. When influenza cases occur, patients should be allowed to rest at home to reduce the spread of the disease.

Schools should take advantage of students’ recess, physical education class, after school and other periods to strengthen classroom ventilation, so as to keep the classroom air circulating and fresh. Every morning, noon and evening, windows should be opened for ventilation, and the ventilation time should not be less than 30 minutes each time. Every day after school, the key places in the classroom should be cleaned and disinfected regularly. Nursery institutions should clean and disinfect students’ toys and other items every day.

Schools should publicize influenza prevention knowledge to teachers and students through radio, LED screens, blackboard newspapers, billboards, leaflets and lectures, do a good job in health education, help teachers and students develop good personal habits such as washing hands frequently, wearing masks and coughing etiquette, and improve their self-prevention ability. In addition, during the epidemic of respiratory infectious diseases such as influenza, schools should try to reduce or avoid large-scale gatherings and other collective activities to reduce the risk of transmission.

　　[Global Network Reporter Zhang Xiaoya] According to Agence France-Presse, the Brazilian government said on March 29th that China and Brazil had reached an agreement to trade in local currency instead of using the US dollar as an intermediate currency.

　　Agence France-Presse said that this agreement will enable China and Brazil, the largest economy in Latin America, to conduct large-scale trade and financial transactions directly, and exchange RMB for the real, and vice versa, instead of using the US dollar as an intermediate currency. The report said that the agreement was announced after the China-Pakistan high-level business forum held in Beijing. In January this year, the two sides reached a preliminary agreement on this.

　　"This is expected to reduce costs … … Promote bilateral trade and investment facilitation. " The Brazilian Export Investment Promotion Agency said in a statement.

　　Agence France-Presse said that China is Brazil’s largest trading partner, with bilateral trade reaching a record $150.5 billion last year.

　　Bloomberg reported on March 25th that before Brazilian President Lula’s visit to China, hundreds of representatives of Brazilian agricultural enterprises "flocked to Beijing" this week, seeking to increase export cooperation with China and attract investment. Reuters also said that the delegation visiting China is huge, including cabinet ministers, governors, parliamentarians and 240 business leaders. Most of Brazil’s beef, soybeans and wood pulp are exported to China. Brazilian Foreign Ministry officials said that Brazil hopes to expand its trade with China beyond the export of iron ore, soybeans, soybean oil and meat, and is ready to sign agreements on technology, innovation and sustainable development.

　　According to the news published on the website of the People’s Bank of China in February, recently, the People’s Bank of China and the Central Bank of Brazil signed a memorandum of cooperation on establishing RMB clearing arrangements in Brazil. The establishment of RMB clearing arrangements in Brazil will be beneficial to enterprises and financial institutions in China and Pakistan to use RMB for cross-border transactions, and further promote the facilitation of bilateral trade and investment.

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.

　　CCTV News:According to the website of the Ministry of Education, in May 2022, the illustration of the eleventh set of primary school mathematics textbooks by People’s Education Publishing House (hereinafter referred to as People’s Education Press) was widely concerned by the society. The leading party group of the Ministry of Education attached great importance to it, and set up an investigation and disposal working group headed by the leading comrades of the leading party group and deputy heads by two members of the leading party group. By interviewing relevant personnel, reading original materials, listening to the opinions of experts in mathematics, ideological politics and art, and soliciting the opinions of front-line mathematics and art teachers, it conducted a serious investigation and verification. The relevant information is hereby notified as follows:

　　After investigation, there are three main problems in textbook illustrations. First, it is not beautiful and upward, and there is a gap with the fundamental requirements of Lide Shuren. The overall painting style does not conform to the aesthetic habits of the public, and some illustrations are ugly and have poor mental outlook, which does not properly reflect the sunny and upward image of children in China. Second, it is not serious and standardized, and some illustrations even have errors. There are too many illustrations, some of which have low professional standards, and some illustrations have scientific and normative problems. Third, it is not meticulous and accurate, and some illustrations are easy to be misunderstood. Some illustrations are sketchy, some lines are poorly drawn and elements are improperly selected, and the proportion of pictures is not harmonious. At the same time, it is also found that some illustrations of problems spread on the Internet are not illustrations of primary school mathematics textbooks of People’s Education Society, and relevant departments have included them in comprehensive investigation and rectification.

　　After investigation, the People’s Education Society, as a textbook compilation unit, did not fully and thoroughly implement the relevant decision-making arrangements of the central government, and did not fully understand the educational function of illustrations in textbooks. The selection system of illustrators was not perfect and standardized, the implementation of the system of three examinations and three schools in textbooks was not strict, the internal error correction system was not perfect, readers’ opinions were not taken seriously, and the problems existing in illustrations were not carefully investigated and rectified in time. When organizing experts to carry out textbook review, the Textbook Bureau of the Ministry of Education lacked guidance and supervision, and did not supervise the investigation and rectification of textbook problems.

　　After investigation, it is not found that there is a problem of economic benefit transmission between the relevant personnel of PEP, the illustrator Wu Yong and the general consultant of the overall design art of teaching materials Lv Jingren.

　Fan Chunhai is a member of the Central Committee of Jiu San Society, a professor at the School of Chemistry and Chemical Engineering of Shanghai Jiaotong University, and a member of the Shanghai Municipal Political Consultative Conference. In 2019, he was co-elected as an academician of China Academy of Sciences.

At the age of 26, he received a doctorate in biochemistry and molecular biology from Nanjing University.

At the age of 33, he was supported by the Outstanding Youth Fund of the National Natural Science Foundation of China.

At the age of 42, his team developed a new method for inducing nano-scale precise mineralization by DNA self-assembly structure, which was published in Nature, and achieved the first breakthrough in the field of DNA nanotechnology by China researchers.

He has been selected as a "highly cited scientist in the world" in the past six years.

At the age of 45, he was elected as an academician of China Academy of Sciences, the youngest among the Shanghai academicians in 2019.

He is Fan Chunhai, member of the Central Committee of the Jiu San Society, member of the Shanghai Municipal Committee of the Chinese People’s Political Consultative Conference, and director of the Shanghai Municipal Committee of the Jiu San Society.

Fan Chunhai’s office is located in the Translational Medicine Research Center of Shanghai Jiaotong University. Next to the simple and bright office is a uniform laboratory. The experimental platform is filled with all kinds of equipment. The window is bright and clean, with few other colors except black and white. Fan Chunhai, who has just been interviewed by his alma mater, is still immersed in the memories of middle school life. Talking about today’s achievements, he said with emotion: "These 20 years happened to be a period of rapid development in China, and the conditions and level of scientific research have undergone tremendous changes. I am glad to catch up with such a good era and let me make great achievements in scientific research."

Fan Chunhai belongs to the Ministry of Chemistry in the published results of the co-election of academicians of China Academy of Sciences. He once won the Tan Jiazhen Prize for Innovation in Life Sciences, one of the most influential awards in the field of life sciences in China. After returning to China, he chose the Shanghai Institute of Applied Physics of Chinese Academy of Sciences as his work unit. Under such a "cross-border", it seems difficult to define his professional field. His explanation for this is: "Subject field and research direction are different concepts, and my research direction has not changed for more than 20 years. I have been engaged in basic research on biosensing since I was a graduate student, just to explore the unknown world and need a broader vision. "

In 1992, Fan Chunhai, who was preparing to take the college entrance examination, applied for the Department of Biochemistry of Nanjing University. "At that time, the choice of biochemistry was blind and I didn’t understand it at all. But I vaguely feel that biochemistry has both biology and chemistry. This name is cool! " Fan Chunhai recalled.

樊春海在南京大学读书时，生物化学系就有浓郁的学科交叉氛围，系里的口号是“学不好化学，就做不好生物化学”。我国生物制药技术研发的开拓者之一，肝素、尿激酶工业的创始人朱德煦时任系主任，中国科学院院士、生命分析化学概念的创导者和生命分析化学国家重点实验室创始人陈洪渊的博士李根喜在生物化学系任教，樊春海在研究生期间得到他们的指导，在生物化学和生命分析化学两条学术传承线的交叉点起步，从事电化学生物传感器的研究，这在当时属于前沿交叉学科。

在前沿学科里不断前进，必须更多地了解国际上的科研动态，“我读书那会儿，经常需要看国外文献，遗憾的是那时看到的文献会滞后至少半年。”樊春海偶然读到《先进材料》（Advanced Materials）杂志对圣塔芭芭拉加州大学（UCSB）艾伦？黑格（Alan J. Heeger）教授（诺贝尔化学奖获得者）的专访文章。文章中黑格表示，自己在获诺贝尔奖后希望做一些以往不敢做的事，比如生物学，特别是生物传感方面的研究。樊春海内心有种一拍即合的快感，随即就向黑格教授申请了博士后，并最终获得认可。

Allen? Haig is a professor in the Department of Physics, but he always advocates interdisciplinary research. Many years later, Professor Haig said modestly in a speech in China: "I knew nothing about biology at that time, even the most basic knowledge such as DNA molecular structure was taught by Chunhai."

"Studying in a Nobel Prize winner’s laboratory, the vision of seeing problems and the way to deal with problems are very different from those in an ordinary laboratory." Fan Chunhai admits that when he was working as a postdoctoral fellow, he realized a deeper connotation about interdisciplinary. Working in Haig’s laboratory, Fan Chunhai had to carry out multiple scientific research projects at the same time, which once overwhelmed him. "You just pick the most important thing to do." This sentence of the tutor made Fan Chunhai enlightened, and he still often guides him to make judgments.

Under the guidance of Professor Haig, Fan Chunhai has made some research progress, and related research work has been published in authoritative magazines such as Proceedings of the National Academy of Sciences (PNAS) and Journal of the American Chemical Society (JACS). Among them, an electrochemical DNA biosensor named E-DNA has been developed, which has been widely praised by international peers. American Chemical Society C&E News rated it as one of the important chemical progress in 2003.

The postdoctoral experience has greatly broadened Fan Chunhai’s horizons and strengthened his confidence in interdisciplinary research. At that time, China was in the initial stage of discipline construction and needed a lot of new blood. In January 2004, Fan Chunhai joined sinap with the support of the "Hundred Talents Program" of China Academy of Sciences. Coincidentally, the day when he joined the defense was the day when the Shanghai Synchrotron Radiation Light Source Project undertaken by the Institute was approved after ten years of hard preparation. This internationally advanced synchrotron radiation light source was completed in only five years. The scientists who participated in the project are not afraid of hardships and hard work, and are praised as "Shanghai Light Source Spirit". In the past five years, under the inspiration of "Shanghai Light Source Spirit", Fan Chunhai built a laboratory from scratch.

In 2008, Fan Chunhai and others established a physical biology laboratory and set up a multidisciplinary research team integrating physics, chemistry and biology. This unique interdisciplinary research atmosphere not only enabled the biosensor research to advance rapidly, but also broadened more frontier research directions. In 2016, the important achievement of the laboratory, "Research on Mechanism, Regulation and Application of Biomolecular Interface", won the second prize of National Natural Science.

In recent years, Fan Chunhai’s team has applied biosensing probes detected in vitro to cells, and is committed to developing frame nucleic acid cell imaging technology. "It doesn’t matter what technology you use, physics or chemistry, or nanotechnology. What matters is that you find some new methods and use some new technologies to observe and decipher the mysteries of life."

"Individual growth cannot be separated from excellent collectives"

Fan Chunhai always appreciates the strength of the collective. Whether it is the study and life in middle schools and universities or the scientific research work, Fan Chunhai believes that the excellent collective has given him the motivation for personal growth.

He recalled that he was never the best student in middle school. "I am a person who knows by learning, not a person who knows by birth." In high school, many of my classmates were excellent. Everyone always discussed problems harmoniously and equally, forming a rich learning atmosphere. Under the professional guidance of teachers, everyone was growing and making progress. In the end, the whole class handed over an excellent answer sheet in the college entrance examination. "

There is such a collective star effect in scientific research, such as the famous Cavendish laboratory, which has trained more than 20 Nobel Prize winners in the past 100 years. "So scientific research has never been alone, and the progress of each group cannot be separated from individual efforts, and the growth of individuals cannot be separated from an excellent group." Fan Chunhai said.

At the beginning of this century, the scientific research conditions in Chinese universities were still relatively difficult, and the information was not as developed as it is now. It was the dream of many analytical chemists in China to be able to publish papers in Analytical Chemistry in the United States. At that time, only Mr. Chen Hongyuan in Nanjing University published papers in this magazine. Fan Chunhai published a paper in Analytical Chemistry as the first author under the guidance of his tutors, and achieved a breakthrough.

Interdisciplinary cooperation is also inseparable from the cooperation between scientists and the whole team. Fan Chunhai, deeply inspired by the "Shanghai Light Source Spirit", hopes to do the same internationally influential research work in Shanghai Institute of Applied Physics, Chinese Academy of Sciences. Mr. Li Mingan and researcher Hu Jun are early explorers in the cross-research of nano-organisms in China. With their guidance and help, Fan Chunhai gradually made it clear that DNA nanotechnology is the starting point to form research characteristics.

DNA nanotechnology is to use the excellent self-assembly and recognition ability of DNA molecules as a nano-material to achieve accurate nano-construction. In 2006, the nano-scale "Map of China" assembled by DNA molecules was successfully created and published in both Chinese and English editions of Science Bulletin, which made an international appearance with China characteristics and became the second published work in the frontier cross field of "DNA origami", which was jointly completed by Fan Chunhai, Hu Jun and Academician He Lin of Shanghai Jiaotong University.

After years of accumulation, Fan Chunhai’s team developed a new method to induce nano-scale precise mineralization by DNA self-assembly structure, which improved the mechanical properties of DNA nano-structure while maintaining its exquisite design, and opened a new door for the construction and analysis of bionic nano-channels. This research achievement was published in the journal Nature, which achieved the first breakthrough in this field by researchers in China.

During the epidemic in COVID-19, due to the lack of Covid-19 RNA reference materials, the performance of nucleic acid detection kits could not be evaluated, and the competitiveness of high-quality domestic kits could not be strongly proved. Faced with this situation, with the deep participation and support of Fan Chunhai’s team, Shanghai Jiaotong University and Shanghai Institute of Metrology and Testing Technology jointly set up a research team and started the research and development project of Covid-19 RNA reference materials. After more than 40 days of repeated trials and improvements, two kinds of "novel coronavirus standard materials for RNA transcription in vitro" were successfully developed. These Covid-19 reference materials, like a "biological standard ruler", can help people to evaluate the indicators of the virus nucleic acid detection kit and help the detection laboratory to confirm the results, thus further reducing the probability of "false negative".

Facing the students from different majors in the team, Fan Chunhai advocates teaching students in accordance with their aptitude and effective guidance. "Students are not managed, but grow up freely under appropriate guidance. My task is to tap students’ interest in scientific research, help them establish correct values and lofty aspirations, and become firm supporters of students."

The road of scientific research has always been bumpy. The life of researchers is more like an ascetic monk to many people, but in their hearts, they are happy because of their love for science. In Fan Chunhai’s view, this happiness is not equal to comfort. He encourages students: "To do scientific research, we should be brave enough to go out of our comfort zone and challenge new things."

"Teamwork and independent thinking are equally important. I hope that every student can choose his own topic under the background of team research, and actively explore various possibilities without relying on authority." Despite his busy work, Fan Chunhai will try his best to take time to communicate with the students face to face, not sitting in danger, but full of relaxation and pleasure.

Fan Chunhai always tries his best to support and encourage students’ decisions and every attempt. Under his training, two students have been supported by the National Science Fund for Distinguished Young Scholars, and four postdoctoral students have been selected for the "Super Postdoctoral Program" in Shanghai in 2020.

Communication and cooperation promoted Fan Chunhai’s scientific research work, and also made him know Li Xinxin, chairman of the Shanghai Branch Committee of the Shanghai Municipal Committee of the Chinese Academy of Sciences of the Jiu San Society. The warmth of the Jiu San Society and the spirit of patriotism, democracy and science attracted him. In 2014, he joined the Jiu San Society.

After joining the club, Fan Chunhai successively served as deputy director and director of the Shanghai Municipal Committee of the Jiu San Society. Although his scientific research work is still busy, he will still find time to engage in popular science work. "Popular science work is actually a kind of inheritance. Whether it is exploring the unknown world or promoting the country’s scientific and technological development, it needs the efforts of generations. However, the concept of scientific research is not exactly the same as that of textbook education in primary and secondary schools. Our popular science work is not a simple strengthening of textbook knowledge, but a broader vision for children. "

In his mind, interests are hierarchical. The interests of primary and secondary school students are often in textbook knowledge and the use of known world knowledge, while real scientific talents need to keep their interest in exploring the unknown world. Spreading the seeds of science in children’s little hearts will not only keep them interested in exploring the unknown world, but also make the city form an atmosphere of obeying and respecting science, which is also the future light of the construction of Shanghai Science and Technology Innovation Center.

Looking back on his own growth experience, Fan Chunhai said with emotion: the cultivation of quality is more important, and the knowledge learned by the school is constantly updated, and the quality cultivated by the school will accompany people all their lives, and good quality will push people forward.

Good quality also made Fan Chunhai on his way to school recognized by teachers. "I am very relieved about what I have told him. No matter whether I get satisfactory results or lessons from failure after completion, he will definitely reply to me and have a serious discussion with me." Professor Li Genxi said of his students, "He is patient in learning and can hold his breath. Once his goal is set, he will be firm and forge ahead. His success is no accident."

In the interview, Fan Chunhai rarely talked about specific difficulties, because he believed that difficulties always existed, and problems could be solved as long as he worked hard and was good at learning and observing. In the communication with his students, Fan Chunhai has always conveyed a belief: optimistic and unyielding. "The development of science is not a full stop, but a comma. The success of scientific research depends on whether you have the courage to face failure and the determination to be more frustrated on the road of exploration. I hope that all students can work hard for the scientific dream of mankind."

It has been nearly thirty years since I entered the university and contacted the interdisciplinary subject of biochemistry. Along the way, Fan Chunhai has grown from an ignorant teenager to an internationally renowned scientist: he was selected as a Fellow of American Association for the Advancement of Science (AAAS), American Academy of Medical and Biological Engineering (AIMBE), international society of electrochemistry (ISE) and royal society of chemistry (RSC), and concurrently served as the deputy editor of ACS Applied Materials & Interfaces Journal of American Chemical Society. Co-chairman of the editorial board of ChemPlusChem, royal society of chemistry, has been selected as a "global highly cited scientist" continuously since 2014. In 2019, he was elected as an academician of China Academy of Sciences, and won the ho leung ho lee foundation Science and Technology Innovation Award, the American Chemical Society’s Lecture Award for Progress in Measurement Science and the 12th Tan Jiazhen Life Science Innovation Award, and in 2020, he was awarded the title of "National Advanced Worker".

Faced with many honors, Fan Chunhai said calmly: "It is curiosity, responsibility and initial heart that lead me to climb to the peak on the road of science." In the future, he said that he will continue to keep his initial heart and forge ahead, lead students to "look up at the stars, be down-to-earth, persevere and make contributions for a long time", constantly explore the frontiers of science, and make due efforts to promote the scientific and technological progress of the country and society.

Fan Chunhai’s goal is to promote his basic research work to clinical application and protect human health. After joining the School of Chemistry and Chemical Engineering of Shanghai Jiaotong University, Fan Chunhai built the laboratory of "Framework Nucleic Acid Design and Nano-medical Diagnosis and Treatment" based on the newly completed national major scientific and technological infrastructure of translational medicine, and devoted himself to transforming and applying the developed new methods of nucleic acid analysis and detection to clinic. In particular, he received the full support of Academician Tan Weihong, Dean of the Institute of Molecular Medicine of Shanghai Jiaotong University, and actively carried out clinical cooperation in Renji Hospital, trying to apply biosensors to the detection of practical clinical samples such as prostate cancer, and exploring the possibility of developing low-cost medical detection.

"The road is long and Xiu Yuan is awkward, and I will search up and down." Fan Chunhai is still moving forward on the road of seeking. In 2019, in order to commemorate the tenth anniversary of the publication, "Nature? The magazine Nature Chemistry specially invited more than 50 internationally renowned scholars to write a monograph on "The Road to Chemistry". As one of them, Fan Chunhai raised a challenging question in the field of chemistry: "An exciting frontier of the discipline is to understand how artificially designed nucleic acid structures are assembled and function in living cells and animals. Creating new tools to control the assembly process of natural and artificial nucleic acid molecules in living cells will probably bring revolutionary changes to the field of nucleic acid chemistry, thus promoting the development of nano-diagnosis and treatment and precision medicine. In the longer term, another promising research direction is to explore and develop DNA or RNA robots with artificial intelligence and work in animals and humans. " (Huang yun)

　　Since the beginning of this year, the city has repeatedly launched special actions to crack down on traffickers, and introduced multi-channel appointment registration and other convenience measures. The Beijing Youth Daily reporter noticed that these convenience measures have gradually been targeted by "traffickers". There are many "traffickers" on self-service machines, WeChat, online reservations and other platforms, and there are also cases of selling numbers on shopping websites in the name of selling concert tickets. At the same time, "online medical care" is also existing in a more hidden posture. Recently, the Municipal Health Planning Commission and 8 departments jointly issued a document to severely crack down on traffickers’ information and "online medical care". In the first half of the year, 733 traffickers were arrested and 6 medical staff were punished.

　　survey

　　The number of squatters has decreased and the field has widened.

　　"Want to number? Expert number ". At 5 o’clock yesterday afternoon, a reporter from Beijing Youth Daily just walked into the outpatient ward building in the west area of Beijing Tongren Hospital, and a middle-aged man took the initiative to ask if it was necessary to register. The "number trafficker" who claimed to be Wang on the business card said that self-service machines, WeChat, online appointments and windows all have ways to hang up the number. "You don’t care which way we take, and you have the number."

　　"On our side, some people are in charge of online booking, some people specialize in registering on WeChat, some people line up at the self-service machine, and some people are at the window". Wang said frankly that he was most used to getting the number from the window and then reversing it. However, due to the increase in registration channels, they also "had to" broaden the field of reversing the number. Take the self-service registration machine as an example. Wang and his associates paid two people to queue up in the independent registration area. "I earn you 200 yuan for an expert number, and I have to give 100 yuan to the person in line, so I also earn 100 yuan money."

　　The "trafficker" has not let go of the WeChat appointment and online appointment registration originally used for limin. Wang said that although he didn’t understand network technology, he "invested" more than 100,000 yuan to buy a number-brushing system. "Hundreds of thousands is not low, but there is no income from investment, don’t you think?" According to Wang, the numbering system is similar to the popular ticketing software before, and they also found two people to take turns staring at it 24 hours a day.

　　As for the situation of cracking down on traffickers in the past six months, Wang said, "There are fewer traffickers now. At the most, there were more than 400 people here, and now there are more than 200 people." As for the reason for the decrease of traffickers, "the management is too strict, and after more registration channels, some patients are diverted, and the market is not as good as before." It is true that some people will quit. " Wang said.

　　Online traffickers wear vests to sell numbers.

　　In addition to the traffickers at the entrance of the hospital, the reporter of Beiqing Daily noticed that the traffickers on the Internet put on the vest of "Yellow Cattle" and continued to sell the number backwards. The reporter of Beiqing Daily tried to input key words such as "registration" and "registration on behalf of" on the webpage, Weibo and Taobao respectively, but found no relevant webpages and contents that provide online registration service. However, two of the five Taobao shops that claimed to operate concert ticketing by using "concert tickets" as the keyword search indicated that they could provide hospital registration service.

　　The reporter of Beiqing Daily randomly selected a concert ticketing Taobao shop in Beijing. After inquiring, it was found that the Taobao shop was also engaged in hospital registration business. All the treasures hanging out of this shop named a ticketing culture discount store are concert tickets, and there is no obvious hospital registration service product. The reporter of Beiqing Daily asked the store whether it can register for the hospital, and the store quickly answered "Yes". Later, the reporter got through the number provided by the store and wanted to hang a well-known oncology expert number. The man who claimed to be surnamed Zhao offered 1000 yuan, while the reporter of Beiqing Daily inquired on the official reservation website that the expert number only needed 14 yuan. Zhao asked to add WeChat first, and then pay him the 200 yuan deposit through WeChat, and then take a photo of the patient’s ID number and send it to him. At the same time, he needed an industrial and commercial bank card opened in the patient’s name. When the reporter of Beiqing Daily asked about the use of the ICBC card, the man surnamed Zhao said: "We have our own channels, so don’t worry."

　　Secret online "medical care" one-stop help registration

　　Although the "fixed position" of online medical care is decreasing, the reporter of Beiqing Daily noticed that medical care can still be found in forums and individual websites. Yesterday afternoon, the reporter of Beiqing Daily found on the Zhihu that someone sent a message entitled "Is it reliable to make an appointment with WeChat WeChat official account in order to go to the Union Medical College Hospital?" At the bottom of the post, a user with the identity of "doctor" replied: "The appointment is reliable, that is, the waiting time is longer." The user also attached his phone number to the back for consultation.

　　The reporter of Beiqing Daily dialed the number as a friend’s consultation. The other party was a young man who claimed to be a doctor, and asked about the patient’s condition and treatment, and gave some suggestions in a professional tone. According to the patient’s condition, he recommended a department corresponding to the hospital to the reporter of Beiqing Daily, and promised to help hang up the expert number. The man surnamed Xue, who claimed to be a professional doctor, revealed that he was a doctor in the oncology department of a well-known hospital, but there was no identity information of the doctor surnamed Xue on the official website of the hospital.

　　Hospital response

　　The hospital has monitored the new trend of traffickers and taken many measures to deal with it.

　　As one of the high-incidence places of "number trafficker" activities, Tongren Hospital said that the struggle against "number trafficker" has never stopped, and at present, it has also noticed that "number trafficker" has increased its patronage of self-service registration machines. Therefore, Tongren Hospital has also taken various measures to deal with it. The person in charge of the security department of Tongren Hospital said, "We have increased the number of security personnel distributed in various self-service registration machines, and the traffickers were immediately stopped."

　　However, the person in charge also admitted that the arrival of summer vacation and the promotion of multi-channel registration have made their struggle with traffickers more difficult. "For example, last week, it was discovered that there were college students in the ranks of traffickers. The traffickers posted summer part-time jobs on the Internet, and the college students who didn’t know the truth were used by them, and they earned jobs in 80 yuan and 100 yuan, and were stopped in time by the public security departments and educated." Multi-channel registration makes Tongren Hospital need to distribute security personnel in various registration channels, and the security force is "stretched".

　　The person in charge of the outpatient department of Tongren Hospital said that the hospital takes measures such as ordinary number unlimited number, hoping that patients will not only stare at the expert number, but also give the traffickers an opportunity.

　　It is claimed to be a "DC slimming drug" imported from Thailand, but it is actually a "new drug". Such a miracle drug for losing weight was even recommended by Wechat business crazily, and the anchor of the live broadcast platform brought the goods.

　　On August 17th, The Paper learned from the Shanghai Anti-drug Office that in recent years, many illegal drugs such as "diet pills" illegally flowed into China from abroad contained psychotropic drugs controlled by China, such as amfepramone, phentermine, diazepam ("diet pills"), nitrazepam, flunitrazepam ("sleeping pills"), modafinil and ritalin ("smart drugs").

　　Among them, "amfepramone" mainly stimulates the nerve center of hypothalamus, which makes people feel full, can control appetite and reduce food intake, but will improve the excitability of the body, and is prone to inexplicable mood swings or insomnia, emotional excitement, etc. Fentamine mostly acts on animal parasympathetic nerves to control appetite or calm down. The research published in The Lancet shows that "with the increase of dosage, cognitive and mental disorders will increase correspondingly", and although such drugs are widely used to lose weight in the United States and other regions, there is no long-term randomized controlled study to prove their effectiveness and safety.

　　And "Diazepam" is similar to the domestic antipsychotic drugs, which are mostly used for anti-anxiety, sedation and hypnosis, and have tolerance and dependence after long-term use.

　　Therefore, from the above-mentioned components and pharmacological effects of "diet pills", it belongs to the definition of drugs (narcotic drugs and refined drugs that can make people addicted to drugs) stipulated by the state.

　　In recent years, with the development of social economy and the improvement of living standards, the general public has higher requirements for their own weight loss and shaping. However, due to the lack of legal knowledge and weak awareness of prevention, and the fact that some unscrupulous businesses even deliberately speculate on the so-called "online celebrity products" for profit-seeking purposes, some online platforms are flooded with all kinds of information and advertisements that are difficult to distinguish between true and false.

　　In this context, due to the lack of legal awareness and anti-virus and anti-drug ability of some people, such "diet pills" have been purchased and used, and the situation has an increasing trend. It not only violates laws and regulations, but also causes its own harmful consequences.

　　Earlier, according to media reports, a woman who lives in Wu Kang Road bought 750 yuan’s "DC diet pills" in the so-called "overseas student purchasing shop" on the online shopping platform. Unexpectedly, after taking them one month after another, the weight loss effect was ordinary, but the police found the door and said that she was suspected of taking drugs. According to the Shanghai Public Security Bureau, more than 200 cases of suspected "DC diet pills" have been investigated this year.

　　According to the Shanghai Public Security Bureau, from the cracked cases, such "diet pills", "sleeping pills" and "smart drugs" have symptoms such as increased heart rate, nausea and headache after taking them; There are even serious situations such as anxiety and depression, mania and irritability, anorexia and world-weariness.

　　With the joint efforts of the city’s anti-drug departments at all levels, the number of traditional drug-related crimes in Shanghai has dropped sharply, and the breeding and spread of drug-related crimes have been further controlled. However, drug-related crimes involving psychotropic and narcotic drugs are on the rise. Since 2018, the illegal use of psychotropic and narcotic drugs in the city has shown a high growth trend.

　　Since the beginning of this year, 85% of drug addicts who illegally use psychotropic and narcotic drugs (such as "diet pills" and "sleeping pills") in Shanghai have used "diet pills" containing controlled drugs.

　　In the next step, multi-departments will jointly continue to increase the following work: first, continue to increase publicity and education for the public to prevent more people from repeating the same mistakes, so as to form a consensus on anti-drug and improve their ability to refuse drugs; The second is to urge all kinds of network platforms to carry out clean-up and rectification, remove, shut down and block the links of individual illegal merchants, and strengthen the sales and advertising review of "drugs"; The third is to strengthen the investigation and control of new types of drugs on the Internet, or items containing drug ingredients and toxic and harmful information, and truly establish an online and offline joint investigation and control mechanism to effectively safeguard the physical and mental health of the broad masses of the people.

　　"Smurfs, milk tea, and smart drugs have always maintained a high degree of sensitivity to these new drugs in Shanghai, and timely detect and crack down on them to avoid circulation. However, the same people should be cautious about drugs to be imported, and don’t be numb and hurt others." Li Jian, director of the Anti-drug Guidance Department of the Political and Legal Committee of the Municipal Party Committee, reminded that citizens are welcome to report actively, and the reward standard has been raised.

　　China news agency, Beijing, May 13 th The National Development and Reform Commission of China reported on the 13th that the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development had compiled the "Development Plan for Urban Domestic Waste Sorting and Treatment Facilities in the Tenth Five-Year Plan". According to the plan, by the end of 2025, the classification and treatment capacity of domestic waste in 46 key cities, including municipalities directly under the central government, provincial capital cities and cities with separate plans, will be further improved; A domestic waste sorting and treatment system has been basically established in prefecture-level cities according to local conditions.

　　This plan puts forward three specific goals: by the end of 2025, the utilization rate of municipal solid waste resources in China will reach about 60%; By the end of 2025, the capacity of classified collection and transportation of domestic waste in China will reach about 700,000 tons per day, which basically meets the needs of classified collection, classified transportation and classified treatment of domestic waste in cities at prefecture level and above; By the end of 2025, the incineration capacity of urban domestic waste in China will reach about 800,000 tons per day, and the incineration capacity of urban domestic waste will account for about 65%.

　　In the past five years, 46 key cities in China have carried out domestic waste sorting, demonstration and guidance, and the coverage rate of residential areas has reached 86.6%, and basically established a system of domestic waste sorting, collection, transportation and treatment. The national domestic waste sorting collection and transportation capacity is about 500 thousand tons per day.
