　　On September 26, the "China Healthy Vehicle Research Program" – "Zero Formaldehyde" Automotive Technology Seminar "sponsored by the China Consumer Product Quality and Safety Promotion Association (hereinafter referred to as the China Consumer Goods Association) and undertaken by China Automotive Data Co., Ltd. (hereinafter referred to as China Automotive Data) was held in Beijing. At the event, the" zero formaldehyde "automobile logo was released, and the first batch of typical cases of" zero formaldehyde "vehicles and advanced formaldehyde control experience in the car were shared. As an industry benchmark adhering to the concept of national car-level healthy vehicle building, Hongqi sent four models, Xinhongqi HS5, Hongqi HS3, the new Hongqi H5, and Hongqi E-QM5, for inspection. After two months, they all won the first batch of" zero formaldehyde "vehicles after rigorous selection in multiple links of room temperature and driving scenarios.

The organizer issued a "zero formaldehyde" car certificate to Hongqi

　　It is well known that formaldehyde has been identified as a Class I carcinogen by the World Health Organization, and it is also one of the main pollutants in the air inside the car. It is hidden in the fabrics, leather, foam, adhesives, plastic resins and other interior materials used in interior parts, which has a non-negligible impact on the health of drivers and passengers. In order to eliminate users’ anxiety about healthy travel, China Consumer Association and China Automotive Data jointly increased the control of formaldehyde in the car. Based on the "Zero" Formaldehyde Automotive Technical Rules (2023 Edition) ", the testing and certification of" zero formaldehyde "vehicles was carried out, and the" zero formaldehyde "automobile logo was awarded to the certified models, which further promoted the technological progress of the automotive industry in the field of in-car health.

　　Rigorous testing, in-depth inspection of technical standards

　　In the test process, China Automotive Data refers to the national standard "Sampling and Determination Method of Volatile Organic Compounds and Aldoxides and Ketones in Vehicles" (HJ/T 400) and the international standard "Internal Air of Road Vehicles – Part 1: Specifications and Methods for Determination of Volatile Organic Compounds in Vehicles in Vehicle Laboratories" (ISO 1 2219-1), and selects automotive products with a mileage of less than 50km and no more than 33 days off the assembly line as the evaluation object; at the same time, in order to investigate the consistency of automobile production quality in mass production status, different batches of production vehicles with a time interval of not less than 30 days are selected in the same sales model and the same configuration model for evaluation and comparison. Simulate the real scene of actual vehicles, select the most commonly used room temperature mode and driving mode by users for data collection and analysis.

　　First, the testing environment is uniformly set to a temperature of 25 ° C, 50% relative humidity at room temperature mode, first open the door for 6 hours, then close the door and window for 16 hours, and then sample formaldehyde in the car; in driving mode, combined with the user entering the car will immediately open the air conditioner usage scenario, first close the door to open the heating for 4 hours, and then open the door to start the air conditioner in the heating state for 60 seconds, perform external circulation air replacement, and then sample formaldehyde in the car. In the face of scientific and rigorous testing, Xinhongqi HS5, Hongqi HS3, Xinhongqi H5, Hongqi E-QM5 rely on the profound accumulation of R & D and manufacturing under the guidance of the concept of health technology, and pass the "zero formaldehyde" assessment with the result that the formaldehyde detection value in each mode is lower than the standard value of the evaluation specification.

Hongqi four models heating mode test scene

　　Realize "zero formaldehyde" and deepen the concept of "national car health"

　　All four models of Hongqi can pass the "zero formaldehyde" car certification, benefiting from the leadership of the health technology development strategy. In recent years, Hongqi has taken comprehensive innovation as the main line and continued to iteratively implement the "Innovation 2030 China FAW Flag Technology Development Strategy", further clarifying the key research directions in many fields such as "intelligent networking", "driving experience", and "safety and health". Among them, "safety and health" is one of the important research and development directions, focusing on users’ multi-dimensional safety needs. In addition to passive safety, active safety, and information security, it also covers active health and intelligent health. With the continuous breakthrough of core technologies, it always escorts users’ travel.

　　Strive to provide users with a green and fresh "zero formaldehyde" breathing environment. Hongqi implements the "low volatility, low odor, low pollution, strong purification" technical route to strictly control the release of formaldehyde and other volatile organic compounds in the car parts. Front forward simulation analysis to optimize material selection, select the best combination of environmentally friendly materials; build a health technology platform, develop and adopt healthy materials and processes, and control the generation of volatile organic compounds such as formaldehyde from the source of the materials used; cooperate with the car air conditioning system to monitor and further purify, and strictly control the release of volatile organic compounds such as formaldehyde in the car parts. In addition, Hongqi’s quality assurance, R & D, procurement and marketing systems have joined forces to establish a cooperation mechanism to implement regular sampling inspections of the VOC and odor performance production consistency of vehicles and parts to ensure the consistency and safety of product quality, so as to achieve "zero formaldehyde", so that users can travel with confidence, peace of mind and happiness.

　　Unafraid of challenges, demonstrate hardcore safety and health capabilities

　　Safeguarding safety and health is the bottom line, and it is also the standard line. Hongqi has always treated user safety and health issues as "penny-pinching". In addition to this car "zero formaldehyde" test, it has also cooperated with the China Automotive Technology Research Center to conduct a new Hongqi H5 three-car collision challenge, completing the domestic 100km/h relative speed collision chain rear-end safety test. This tests the protection ability of passive safety systems such as the strength of the vehicle’s body structure and the stability of the restraint system. After the collision, the dummy in the car was basically undamaged, fully demonstrating the strong safety level of Hongqi.

　　In addition, Hongqi HS3 was also selected to participate in the 2023 CCPC China Production Car Competition, and won the "three victories" in Chongqing Public Station, Turpan Extreme Station, and Guangzhou Professional Station. It was not afraid of various challenges such as safety and performance, and finally won the annual championship of the compact SUV group. In the Guangzhou professional station competition, it successively won the first results of the elk test, low braking, 8-character ring and other test groups, and showed outstanding performance in emergency obstacle avoidance, braking performance, body stability, etc., fully ensuring the safety performance of the vehicle. In addition, in the noise test of the vehicle at a constant speed, the Hongqi HS3 was 55.8dB in the 60km/h driving state and 58.1dB in the 80km/h driving state, creating a healthy and comfortable driving environment for users with excellent quiet performance.

Hongqi HS3 participated in the low attachment braking test and won the first place in the group

　　The automotive market is competitive, and the industrial landscape is changing rapidly. Major brands are attracting users’ attention in the form of volume prices, volume configurations, and longer and longer volumes. However, Hongqi has always been firmly user-centered, not blindly following or superficial. With clear strategic support and innovative independent technology, it continuously improves product quality and service levels. Whether it is a "zero formaldehyde" in-car environment or top-level passive safety, it is the best evidence that it makes every effort to create a safe and healthy car-owning life for users. In the future, Hongqi will continue to work hard to continuously refresh the user’s safe and healthy car experience to a new height, so that every user can "drive a healthy car and enjoy a better life".

The high subsidies of internet service platforms such as food ordering platforms and taxi-hailing software have provided consumers with a lot of benefits, but at the same time, some "moths" have also found this "fertile ground", and swiping and cheating are commonplace in the industry, causing huge losses to Internet companies.

?

?

This year, the Putuo District Procuratorate handled a series of cases of defrauding subsidies from the "Ele.me" online food ordering platform, and uncovered a number of "scamming moths". The procuratorate attaches great importance to the problem of new types of economic crimes on the Internet, and strives to crack down on the hidden "moths" in the internet service industry to escort the economic transformation and development. Through three typical cases, the prosecutor shows you the tricks of scammers and reminds relevant parties to be vigilant.

?

?

Case 1: "No business" – self-made "plug-in program" to operate the first order red envelope

?

?

Zheng often used "Ele.me" to order food when he was working in the company. During one order, he learned how to swipe "Ele.me" first-order discount red envelopes indefinitely, so he came up with the idea of opening an online store to sell first-order discount red envelopes.

?

?

In May 2015, Zheng opened a store online, registered new users by means of renting a large number of mobile phone numbers online to set up call transfer, using Android mobile phone emulator software to make up a mobile phone environment, and illegally obtained the first order preferential red envelope of the "Ele.me" food delivery platform (about 15 yuan per order business subsidy). Then the first order preferential subsidy qualification and the operation tutorial for obtaining the first order subsidy qualification were sold in the online store. In just a few months from May to October, Zheng defrauded the "Ele.me" first order preferential subsidy of more than 90,000 yuan.

?

?

Recently, Zheng was prosecuted by the Putuo District Procuratorate on suspicion of fraud.

?

?

Case 2: "Internal and External Collusion" – Subsidies for launching virtual restaurant sets

?

?

The so-called day and night defense, it is difficult to prevent thieves. In the fraud case handled by the Putuo District Procuratorate this year, the "Ele.me" company also encountered internal employees guarding themselves.

?

?

Li, the regional manager of the "Ele.me" food delivery platform, met the restaurant owners Zhao, Qian, and Sun through business contacts. In 2016, the three found Li, hoping that he would use the opportunity to work in the company to facilitate the registration procedures of the three-person platform.

?

?

So Li used the work accounts of himself and his subordinate Chen to register a number of fake restaurants with no physical stores on the "Ele.me" platform, and formulated and approved a series of rebate activities for these restaurants. After that, Zhao, Qian, and Sun pretended to be customers many times to order food in fake restaurants, and at the same time took orders as restaurant owners, staging a good show of "buying and selling".

?

?

Li colluded with the restaurant owner inside and outside, used false orders to swipe orders, and illegally obtained more than one million yuan in rebates from "Ele.me" ordering platform activities. Recently, Li, Zhao, Qian, and Sun were prosecuted by the Putuo District Procuratorate on suspicion of duty embezzlement.

?

?

Case 3: "Careful planning" – the swiping team sends "spies" to infiltrate the company

?

?

At the end of 2015, Zhou and his college classmate Wu conspired to earn "Ele.me" company activity subsidies by swiping orders. After understanding the daily operation of "Ele.me" company, Wu proposed to let Zhou first sneak into "Ele.me" company and help Wu’s team swipe orders internally.

?

?

In March 2016, Zhou entered the "Ele.me" branch as a regional marketing manager through an interview, and had the approval authority to launch the restaurant. He then used the false catering store information provided by Wu to launch 51 virtual restaurants and plan high-value rebate activities.

?

?

Wu’s swiping team immediately used more than 500 miscellaneous mobile phones and calling cards to register multiple accounts to order food in the virtual restaurant, illegally obtaining subsidies and rebates for new users’ first orders on the "Ele.me" ordering platform.

?

?

After review, Zhou took advantage of his position to defraud "Ele.me" company’s preferential activities and rebates totaling more than 570,000 yuan. Zhou was eventually arrested by the Putuo District Procuratorate on suspicion of duty embezzlement.

?

?

[Prosecutor says]

?

?

The prosecutor said that with the Internet of taxi-hailing, catering, tourism and other service industries, there are more and more cases of fraud and compensation of swiping orders. It is not only the "Ele.me" food ordering platform that has been ravaged by "swiping order borers", but other internet service platforms have also generally suffered from swiping orders.

?

?

It is worth noting that many ordinary users feel that swiping orders and cheating subsidies are harmless, and can only be regarded as illegal operations at most. Even they are enjoying the "benefits" brought by this gray industry.

?

?

Taobao still has a market for selling "first order" red envelopes; Baidu search enters "brush order", showing nearly 100 million search results, and various brush order platforms and brush order tutorials are overwhelming; within Internet companies, not only have many employees taken advantage of their positions for personal gain, but there are also cases of franchisees cheating and swiping orders.

?

?

In this regard, the prosecutor reminds those who are swiping orders or have the intention to do so that the Internet is not an extrajudicial place, and malicious swiping may violate the criminal law, and do not regret it because of greed.

Speaking of pickup truck models, I believe most people will think of Ford F-150 (parameter picture), while domestic pickup trucks are mostly positioned as agricultural vehicles. Until the appearance of the Great Wall Cannon, everyone changed the impression that domestic pickup trucks are low-end and simple. Recently, we have obtained a set of spy photos of the interior of the off-road version of the Great Wall Gun from relevant channels. Compared with the ordinary version, the interior of the new car has changed greatly.

As can be seen from the picture, the center console of the new car adopts a very straight line design, so the full LCD instrument is also different from the traditional model. In the middle, there is an embedded central control panel, and the air conditioning outlet is located below the central control panel, and some silver physical buttons are retained, which is equally exquisite. In addition, it can be seen that the new car adopts an irregular gear handle design, and there are two knobs around it, one of which should be the driving mode knob.

Then let’s review the appearance. As can be seen from the previous declaration, the whole shape of the new car has a very strong American pickup style. In addition to a large number of black kits, the front of the new car also has a large area of chrome-plated material, so it is both wild and exquisite.

In the power part, the new car will be equipped with a 2.0T gasoline turbocharged engine of the Great Wall GW4C20B model, with a maximum power of 221 HP (165 kW). As for the specific four-wheel drive structure, we will announce it as soon as there is news.

　　In recent years, with the increasing myopia rate of children and adolescents, how to effectively prevent myopia and protect eyes in like eyes has attracted much attention. Jishui County, Ji ‘an City, Jiangxi Province, organized a professional medical screening team to come to schools and kindergartens recently to provide children with eyesight tests and file the children’s eye health.

　　Zhi Zhao Zhu Huiqing wrote

　　The COVID-19 epidemic has changed people’s way of life and students’ way of learning. There are fewer outdoor activities, more TV and computers, and online classes become the norm. Whether adults or children, the main learning and entertainment have become using computers, playing mobile phones and watching TV. Using your eyes at close range for a long time undoubtedly aggravated the damage to your eyes.

　　Recently, the National Health and Wellness Commission issued the Guidelines for the Prevention of Myopia among Children and Adolescents during the COVID-19 Epidemic (hereinafter referred to as the Guidelines), which specifically mentioned that outdoor sports should be increased. According to relevant sources, proper outdoor exercise can not only improve children’s health, but also play a key role in the prevention and control of myopia among children and adolescents.

　　Increase daytime outdoor activities

　　Relieve excessive eye use at home

　　During the COVID-19 epidemic, home schooling became an important way for children to learn. Ms. Liang, a parent of a junior two student, said that children used to have physical education class every day at school, and they could exercise by walking on the way to and from school. Although they read books for a long time, they sometimes have a rest, but now they are bored at home staring at their mobile phones and tablets, having live classes, submitting and revising their homework every day. The child’s eyesight has become blurred, which makes her very worried.

　　Experts say that daytime activities can not only prevent myopia, but also control the development of myopia for children who have already developed myopia. The "Guidelines" specifically mentioned that it is necessary to increase children’s outdoor activities and advocate increasing outdoor activities in open, ventilated and sparsely populated places, which is conducive to preventing myopia. This is not contradictory to the prevention and control of the epidemic, but it is necessary to do a good job of prevention and control.

　　First of all, children should try to avoid close contact with others when they are outdoors, and wear masks when they need to communicate with other children or others. Second, young children should be accompanied by adults for outdoor activities. At the same time, parents should pay attention to children’s hygiene, especially hand hygiene, and be sure to tell children not to touch their eyes, nose and mouth with their hands. Third, children should not spit everywhere during outdoor sports. When sneezing and coughing, they should pay attention to covering their mouth and nose with paper towels and elbows. Fourth, take off your coat and wash your hands in time after going home from outdoor sports.

　　Choose regular electronic products

　　Anti-blue light equipment is not necessary

　　Mr. Yang, a citizen of Beijing, bought the latest tablet computer and anti-blue-light glasses in order to make his children’s online classes not hurt their eyes. Although the expenses are not small, he thinks it is worthwhile for their children’s eyesight.

　　In this regard, experts suggest that the selection of video tools should adhere to the principle of "rather big than small", and the order of selection is projection, TV, computer, tablet computer and mobile phone. Improper screen size, display screen refresh rate and use distance can also easily lead to visual fatigue, and then cause eye diseases such as myopia or dry eye, while the resolution of the display generally does not cause visual fatigue, so it is suggested to set the parameters of the screen: the height should be kept at a level or slightly lower position in the eyeball and video center; The distance is 4-6 times of the diagonal length of the electronic screen; The refresh rate of CRT display screen of cathode ray tube is generally 75-85 Hz. If it is a liquid crystal display screen, there is no need to adjust the refresh rate. In addition, the ambient light should be suitable. When using electronic products at night, it is necessary to turn on the light and dim the brightness of the screen to 30%. Screen saver wallpaper with green background can be set to relieve eye fatigue.

　　Wei Wenbin, director and chief physician of the Department of Ophthalmology of Beijing Tongren Hospital, said that there is an over-interpretation of the harm of blue light in the society at present, and there should be no direct relationship between the prevention of blue light and visual fatigue and the prevention and control of myopia. Blue light can be divided into long-wave blue light and short-wave blue light. Only short-wave blue light will affect eye health, but it needs long-time, high-intensity and uninterrupted irradiation. The electronic products that pass the quality inspection have filtered harmful short-wave blue light. Therefore, in daily life, there is no need to install anti-blue light equipment when using electronic products produced by regular manufacturers.

　　Tables and chairs match the height of children.

　　Try not to use the dining table instead.

　　The desks and chairs that match the height of children can protect eyesight and prevent myopia. Inappropriate tables and chairs will have a great impact on sitting posture and sight distance, leading to diseases such as myopia and spinal curvature. During the epidemic period, a large number of students studied at home, not equipped with special desks and chairs, and some used dining tables, dining chairs or beds instead.

　　In this regard, Guo Xin, director of the School Health Center of Beijing CDC, said that the dining table and dining chair are often too high, while the bed is soft and low, which cannot replace the regular desks and chairs.

　　For families with adjustable desks and chairs, according to the height of children and the height range table of various models of desks and chairs for primary and secondary school students, the table height and seating height suitable for children can be found. According to this principle, the thighs and calves should be vertical, the back should be straight, the upper arms should droop, and the elbows should be 3-4 cm below the desktop to correct the desks and chairs. Families without adjustable desks and chairs should also make adjustments according to the above principles. When the table or chair is too short, the table or chair should be raised.

　　Eye movement exercises are limited.

　　And don’t rely on eye drops.

　　Xiao Gang, a 10-year-old, stayed at home for online classes during the epidemic, staring at the computer for a long time during the day, often watching TV and playing games after studying, and sometimes staying up late to read books. Recently, the mother found that her son began to blink frequently, and there were always secretions in his eyes, and he rubbed his eyes from time to time. Xiao Gang’s mother is very worried.

　　The eyeball is like a camera. To take a clear picture, you need to focus on the negative. The process of focusing is called adjustment, which depends on the movement of the muscles in the eye. Looking near is like spring contraction, that is, adjusting tension, while looking far is spring relaxation, that is, adjusting relaxation. Excessive adjustment may lead to myopia. Increase outdoor activities, increase the time to see the distance, you can effectively relax the adjustment.

　　Wei Wenbin said that during the epidemic period, there were some "winking", "slanting head and slanting brain" and various eye exercises focusing on eye movement. This kind of exercise is actually the exercise of extraocular muscles, which is helpful to some children with oblique amblyopia who need to train their binocular vision function, but it can’t relieve the fatigue of intraocular muscles well, so it can’t slow down the development of myopia and visual fatigue. To prevent and control myopia, we should emphasize the formula of "20-20-20", that is to say, look for nearly 20 minutes and look at 20 feet (6 meters) for more than 20 seconds, so as to relax the muscles in the eye and relieve visual fatigue.

　　At present, there is no drug promotion to improve vision and control the development of myopia in China. In recent years, studies have found that low concentration of atropine can delay the development of myopia in children. However, the low concentration of atropine eye drops is not a magic medicine. Some children will be afraid of light, unable to see clearly at close range, and allergic reaction to atropine. There are still some children who can’t effectively control the progress of myopia. So don’t rely on eye drops to prevent and control myopia, reduce the use of eyes at close range, pay attention to eye posture and increase outdoor exercise are the most important ways to prevent and control myopia. At the same time, we should go to the hospital early for health examination, monitor the occurrence and development trend of myopia and intervene in time.

　　High myopia or blindness

　　Wearing glasses is the most effective way to delay

　　Experts suggest that preschool children should be more strict with the use of electronic screens than school-age children, and the use of electronic products should be minimized. The time for watching cartoons should not exceed 15 minutes at a time, and the cumulative time should not exceed 1 hour every day; Ensure more than 10 hours of adequate sleep, balanced nutrition, no picky eaters, no overeating, eat less sugar, eat more fruits and vegetables, and drink no less than 1500 ml of water every day; Choose an appropriate sport or game.

　　Wei Wenbin emphasized that myopia can’t heal itself. Some high myopia above 600 degrees is pathological myopia, which is an important cause of blindness. The most critical purpose of juvenile myopia treatment is to prevent it from developing into high myopia and pathological myopia. Therefore, once myopia is diagnosed, it should be intervened.

　　It is recommended to wear glasses when the degree is greater than 100 degrees. First of all, we should go to the hospital for identification. After ciliary muscle paralysis, mydriasis and optometry can distinguish true myopia, asthenopia and pseudomyopia. True myopia cannot be recovered by means of instrument training, and there is no effective cure at present. The reason why instrument training improves vision may be that the patient is pseudomyopia, or that the naked eye vision is improved by training ciliary muscles. However, this state of myopia has not been lifted, so there is no way to stop the rapid development of myopia.

　　It is said on the Internet that children with low myopia get worse after wearing glasses, which is a natural development of myopia, not caused by wearing glasses. It is the simplest, safest and most effective way to delay this process by wearing appropriate glasses. With the improvement of the epidemic prevention and control situation, it is now possible to go to the hospital for optometry and glasses. When visiting a doctor, we should pay attention to strictly implementing epidemic prevention measures, make an appointment for optometry in advance, see a doctor at different times to reduce gathering, wear a mask for protection, and cooperate with the examination according to the doctor’s advice.

　　Attention should be paid to the vision problems of the elderly

　　According to the 45th Statistical Report on the Development of Internet in China, by March 2020, the number of Internet users in China had reached 904 million, and the number of mobile phone users had reached 897 million. Among netizens, netizens aged 50 and above account for 16.9%, and the number exceeds 150 million. The Internet continues to penetrate into middle-aged and elderly people.

　　Today, with the rapid development of the mobile Internet, the use time of small-screen mobile terminals for the elderly has doubled, which has greatly enlarged the eye problems of the elderly in the small-screen era. Many of them suffer from vision problems such as cataracts or glaucoma. According to the statistics of Ophthalmology Branch of Chinese Medical Association, the incidence of cataract in people aged 60 to 89 in China is about 80%, and the incidence of cataract in people over 90 years old is as high as 90%. Cataract patients are often accompanied by blurred vision, ghosting, photophobia, glare, dark shadows in front of their eyes, deepening myopia and other symptoms. Without surgical treatment, they may eventually become blind, which will seriously affect their normal work and life.
