The yellow peaches sent to the e-commerce station will be sent to the transshipment center of the logistics company, sorted and transported to all parts of the country to reach the consumer’s table.

　　"Today, a total of 30,000 to 40,000 pieces of yellow peaches and early crisp pears were issued, about 260 tons." On July 7, Cao Jie, deputy general manager of Dangshan Shentong Express Co., Ltd. said excitedly that since the end of last month, the company has entered the busiest season of the year, with 36 large trucks running at full speed. Within 24 hours, the yellow peaches and early crisp pears transported that day will go directly to Jiangsu, Zhejiang, Shanghai and Anhui; Arrive in Beijing, Shanxi, Shaanxi and other places within 48 hours; Arrive in Guangzhou and Shenzhen in 72 hours.

　　To measure whether a place’s e-commerce is developed, just look at logistics: at present, more than 400 large and small logistics companies in Dangshan County have started to operate rapidly, and the traffic police department has to send more police to ease traffic.

　　"We obviously feel that the market has changed this year. At this time last year, most of our logistics was canned peaches, and most of this year was fresh fruit; Last year, the purchase price of yellow peaches was around one yuan a catty. This year, the quality yellow peaches have risen to three or four yuan a catty. " Cao Jie introduced that through the development of telephone companies in recent years, Huangtao has become the "Huang Jinguo".

　　"Dangshan is the origin of’ Dangshan Crispy Pear’, which is well-known at home and abroad, and has the reputation of being the pear capital of the world; Dangshan is also one of the three major producing areas of yellow peaches in the world. The yellow peaches in Dangshan are suitable for fresh sale in the market and for processing and exporting canned peaches. The canned yellow peaches produced from Dangshan yellow peaches sell well in Europe, America, Japan, South Korea and Southeast Asian countries. " Tao Guanghong, the county magistrate of Dangshan County, introduced that Dangshan took advantage of internet plus to make peaches "pears" all over the world-4 billion Jin of yellow peaches, crisp pears, apples and other fruits were exported to all parts of the country; At the same time, Dangshan vigorously promoted e-commerce poverty alleviation. By building and operating 139 village-level e-commerce poverty alleviation stations, it formed a three-level e-commerce network support for counties, towns and villages, helped poor villages sell characteristic agricultural products, effectively promoted poor people to start businesses and find jobs, and embarked on the road of getting rid of poverty and becoming rich.

　　Cctv newsAccording to the National Bureau of Disease Control and Prevention, research shows that myopia is the result of many factors, and children and adolescents are generally susceptible. On the basis of considering multiple causes, such as environmental and behavioral factors, genetic factors, eye evolution law and social and cultural factors, this paper puts forward intervention techniques for children and adolescents’ myopia, and adopts three-level prevention strategies to implement comprehensive public health intervention measures to prevent, reduce and slow down the occurrence and development of children and adolescents’ myopia.

　　First, the prevention of public health intervention technology

　　(1) Monitoring, evaluation and intervention of myopia risk behaviors.

　　1. Students’ eye behavior evaluation. For students of different school ages, the eye behavior evaluation form for kindergarten and primary school students in grades 1-3 (parent version) (attached table 1) and the eye behavior evaluation form for primary school students in grades 4-6 (student version) (attached table 2) were used to evaluate the eye behavior of kindergarten to middle school students, and to identify the risk behavior factors that affect myopia of children and adolescents, such as insufficient outdoor activities, excessive use of electronic products, lack of sleep or large social time difference, reading and writing.

　　2. Application of evaluation results. According to the specific risk factors, teachers and parents should change the bad eye behavior of children and adolescents (the contents listed in Schedule 1 and Schedule 2 can be used as the contents of health education and behavior standards).

　　3. Promote good eye use behavior with appropriate technology. Actively develop or use the existing appropriate technologies for myopia prevention and control, and apply them to promote the development of children and adolescents’ rational eye use behavior. For example, the height of the desk and chair measuring ruler (desk and chair deployment measuring ruler), correct reading and writing posture wall chart, light monitor, eye relaxation exercises, etc.

　　(2) The visual environment of schools, families and communities has been improved.

　　1. The construction of school visual friendly environment. Schools should provide students with good lighting and lighting environment according to the Hygienic Requirements for Prevention and Control of Myopia in School Supplies for Children and Adolescents (GB40070-2021). Each class should be equipped with desks and chairs to allocate measuring ruler, measure the height range of students regularly and adjust the desks and chairs in time. Each classroom should be equipped with adjustable desks and chairs or 2-3 types of desks and chairs according to the height range of students. The desks and chairs of the same type can be placed in columns, and the height of desks and chairs should be adjusted individually once every semester according to the height and sitting height of students. According to the perspective of students’ seats, the lighting situation in the classroom and the changes of students’ eyesight, the school will change students’ seats at least once a month. Multimedia classrooms should choose large-size projectors or computer screens. Under the same screen size, choose products with high screen resolution.

　　2. Building a family visual friendly environment. The desk should be placed so that its long axis is perpendicular to the window. When studying during the day, natural light enters from the opposite side of the writing hand to avoid direct sunlight. The average illumination value of the desktop is not less than 300lx. Parents should adjust the height of desks and chairs regularly according to the growth and development of children and adolescents. Children and adolescents should be equipped with desk lamps that have passed the national compulsory product certification (CCC certification), and children and adolescents should turn on the ceiling lights in addition to using desk lamps when studying at night. When online learning is needed, electronic products with large screen such as TV and desktop computer should be selected, and electronic products with high screen resolution should be selected under the same screen size. The viewing distance of TV is not less than 4 times the diagonal distance of the screen, the horizontal viewing distance of computer is not less than 50cm, and the viewing distance of mobile phone is not less than 40cm. Children and teenagers don’t put televisions and computers in their bedrooms. They use dark curtains at night and don’t turn on the night light to sleep. Guide children and adolescents to avoid or reduce exposure to high brightness and blue light-rich electronic products at night.

　　3. Community visual friendly environment construction. Green space can prevent or slow down the occurrence and development of myopia in children and adolescents by increasing outdoor time and reducing screen time. Reasonable green land is set up in the community, with certain activity facilities, which is suitable for carrying out all kinds of parent-child outdoor activities. The night light environment of residential quarters should comply with the current national standards. Except for indicative and functional signs, advertising lighting is not suitable for residential buildings (districts). The glare limit of night lighting lamps in residential and pedestrian areas, the maximum allowable value of illumination on the outer surface of windows of residential buildings, and the maximum allowable value of luminous intensity of night lighting lamps in the direction of rooms should be strengthened in accordance with the Planning Standard for Urban Lighting Construction (CJJ/T 307-2019).

　　(3) 2 hours of outdoor activities and 1 hour of physical exercise during the day.

　　1. Ensure 2 hours of outdoor activities every day and 14 hours every week. According to the Grade and Description of Recommended Contents for Prevention and Control of Children and Adolescents’ Myopia by Outdoor Activities (Attached Table 3), school-age children have two hours of outdoor activities during the day, which are carried out inside and outside the school. The insufficient time for daytime outdoor activities on school days should be made up on weekends and reach at least 14 hours of daytime outdoor activities every week. Kindergarten children advocate three hours of outdoor activities during the day and put more conservation content outdoors.

　　2. Implement one-hour daytime outdoor activities on campus. The school arranges a 30-minute recess activity in the morning and afternoon, emphasizing outdoor activities and not sticking to the form and content of activities. Try to go to physical education class outdoors, and some indoor courses, such as class meetings, can be held outdoors. Set up outdoor activities interest groups and actively carry out various forms and rich contents of outdoor activities. Arrange extracurricular sports homework and provide high-quality exercise resources. Teachers should promptly remind students and class "eye guards" to supervise students to walk out of the classroom for 10 minutes between classes.

　　3. Grasp the one-hour outdoor activities outside school. It is recommended that children and adolescents have a full or staged walking to school, and junior students should be accompanied by their parents. Parents encourage and actively participate in children’s extracurricular activities, complete extracurricular sports homework, and go outdoors and go to nature with their children on weekends and holidays. Schools, parents and students cooperate, actively explore the development of peer-to-peer school groups, increase the time of outdoor activities during the day, enhance exchanges between students, and reduce parental companionship.

　　4. Exercise for 1 hour every day. According to the requirements of myopia prevention and control, children and adolescents should be outdoors for 2 hours every day, but according to the requirements of physical and mental health promotion, children and adolescents should be engaged in moderate to high-intensity physical activities for at least 60 minutes every day, mainly aerobic exercise. High-intensity aerobic exercise and muscle and bone strengthening exercise should be carried out at least three days a week. Taking physical education class as the starting point, the school guides students to carry out physical exercise, and brings the daytime outdoor physical exercise time into the range of 2 hours of daily outdoor activities.

　　(4) Health education for all teachers, students and parents.

　　1. Strengthen teachers’ health education ability. The school cooperates with public health professional institutions and medical colleges and universities to organize teachers to carry out health education and training on myopia prevention and control, so that teachers can master myopia prevention knowledge. Trained teachers popularize myopia prevention and control knowledge through health education classes, parent-teacher conferences, and myopia prevention and control theme class meetings.

　　2. Improve students’ eye health literacy. Students should receive at least one health education course or theme class meeting for myopia prevention and control every semester to learn the knowledge and skills of eye protection in like eyes. Teachers guide students to make handwritten reports on myopia prevention knowledge, and carry out knowledge contests, group discussions, role-playing, etc. to improve students’ myopia prevention and control ability. Students will bring the knowledge of myopia prevention and control they have learned and mastered in school back to their families, which will influence their parents and give play to the role of "small hands and big hands" in myopia prevention and control. Advocate the school to train an "eye protector" or preacher in each class, publicize the knowledge about vision protection, and urge students to go out of the classroom during recess.

　　3. Enhance parents’ awareness of vision protection. Parents should take the initiative to learn like eyes’s knowledge and skills of eye care, educate and urge their children to use their eyes scientifically, improve family lighting, adjust the height of desks and chairs, and correct the thought and behavior of "paying more attention to treatment than prevention", so as to realize the myopia prevention and control situation of "holding hands with big hands".

　　4. Increase the construction of social supportive environment. Mobilize experts to enter schools and society, popularize scientific knowledge of myopia prevention, and educators and children and adolescents identify scientific vision correction measures. Experts and scholars actively compile and publish popular science materials and books on myopia prevention and control health education, and make new media health education materials. Professional institutions, schools and communities should join forces to promote the dissemination and sharing of health education information and improve the coverage and efficiency of health education by using mobile health platforms or technologies, such as smart phone applications, SMS services and telephone intervention. Severely crack down on the false and illegal marketing and propaganda behavior of children and adolescents’ myopia prevention and control products.

　　Second, the secondary prevention of public health intervention technology

　　(1) Vision health screening.

　　Establish a regular vision screening system, carry out poor vision screening, the screening frequency is not less than 2 times per academic year, standardize the recording of inspection contents, and establish information management of vision health. Pay attention to the standardization of screening and filing process, strengthen quality control, and implement closed-loop management of grading after screening. With the help of artificial intelligence technology, the degree of automation of vision screening is improved, and the work efficiency and popularization are improved.

　　(2) Early warning management of myopia.

　　Timely analysis of children’s and adolescents’ visual health, early screening of myopia and other ametropia, dynamic observation of the development and changes of children’s and adolescents’ refractive status in different periods, early detection of myopia tendency or trend, establishment of myopia early warning model, and formulation of applicable and feasible intervention measures to slow down the rapid and severe development of myopia. Combined with vision screening and file establishment, it is suggested that children and adolescents with normal vision but with high risk factors of myopia or insufficient hyperopia reserve should change their high-risk behaviors, and schools, families and communities should cooperate to increase outdoor activities during the day, reduce the behavior of using eyes at close range and improve the visual environment. For those with pre-myopia, we should give high-risk early warning and focus on intervention. It is suggested to go to professional institutions to receive professional examinations such as medical optometry, make a clear diagnosis and take corresponding measures in time to control and slow down the occurrence and development of myopia in children and adolescents.

　　Three, three prevention of public health intervention technology

　　(1) scientifically correct myopia.

　　For children and adolescents who are already nearsighted, parents should be instructed to take their children to professional institutions for examination and correction in time. If it is determined that they need to wear glasses after professional examination, parents should choose glasses with appropriate degrees for their children according to the requirements of doctors or optometrists, wear glasses according to the doctor’s advice, and conduct regular follow-up.

　　(2) Preventing and controlling the aggravation and complications of myopia.

　　For children and adolescents with early onset of myopia or rapid development of myopia, specialists should adopt optical correction, drug correction or traditional Chinese medicine to slow down the progress of myopia. Parents should go to regular medical institutions, choose measures suitable for their children under the guidance of doctors or optometrists, and use them according to the doctor’s advice. For children and adolescents with fundus pathological changes and other complications, parents should take their children to professional medical institutions for treatment by specialists in time.

　　Fourth, the specific implementation measures

　　(1) Grasp early and small, and implement it in the whole life cycle.

　　1. The implementation of vision health management pass forward. Early detection of the shortage of hyperopia reserves and timely intervention measures are the key to move forward the prevention and control of myopia for children and adolescents. Move forward in the prevention and control cycle, grasp early and grasp small; Move forward in the prevention and control link, from treatment to early warning; Move forward in the sense of prevention and carry out early intervention for students with healthy vision. Move the myopia defense line forward to pregnancy, infants and preschool stage. Strengthen parents’ and teachers’ awareness of myopia prevention and control, and regard infants, preschool children and lower grades of primary schools as the key links of myopia prevention and control.

　　2. Promote the prevention and control of myopia in the whole life cycle. From the perspective of the whole life cycle, it focuses on the potentially sensitive periods such as pre-pregnancy, pregnancy, infants, preschool, school age, etc., so as to reduce the impact of biological, environmental and behavioral risk factors in each period on the visual health of children and adolescents. From pre-pregnancy, pregnancy and perinatal period, develop a healthy lifestyle, monitor health status in real time, and reduce the risk of gestational diabetes, hypertension and premature delivery, so as to reduce the risk of myopia in children and adolescents. Implement the "Standard for Eye Care and Vision Examination Services for Children Aged 0-6", establish children’s eye health files, and make one file for each person, which will be transferred in real time with children and adolescents entering school. Popularize the scientific knowledge of children’s eye care to parents, and guide families to actively accept children’s eye care and vision examination services. Carry out health guidance, don’t touch the electronic screen before the age of 3, preschool children should try to avoid touching and using video electronic products, reduce the time of using their eyes at close range, increase the time of outdoor activities, maintain correct reading and writing posture, develop good sleep habits and ensure adequate and regular sleep. At school age, we should advocate at least one hour of outdoor activities in and out of school every day, reduce long-term close eye use and maintain adequate regular sleep. Implementing myopia prevention and control from the whole life cycle can realize the forward movement of myopia prevention and control and improve the vision health in the whole life cycle.

　　(B) the combination of prevention and control, the whole population and key population strategy.

　　1. The whole crowd strategy. Children and adolescents are generally susceptible to myopia, so it is necessary to take the whole population strategy to prevent and control myopia, carry out health education on myopia prevention and control, increase outdoor activities during the day, reduce long-term use of eyes at close range, build a visually friendly environment and other public health intervention measures to do a good job of prevention and control at the first level of the whole population.

　　2. Key population strategy. According to the stages of myopia, corresponding intervention measures should be carried out to reduce the risk of rapid development of myopia. For those with normal vision and sufficient hyperopia reserve, prevent the hyperopia reserve from being consumed prematurely. The main goal of prevention and control of myopia is to slow down the occurrence of myopia. Low myopia should control the progress of myopia, while high myopia should prevent fundus lesions and reduce the risk of blindness.

　　(three) demonstration and guidance, strengthen the prevention and control and intervention process and effect evaluation.

　　1. Pilot first, demonstration leading. Construct a six-in-one comprehensive prevention and control strategy of government leadership, responsibility of competent departments, monitoring of professional health institutions, school leadership, family cooperation and students’ subjectivity. Disease control institutions at all levels rely on the monitoring of common diseases and health influencing factors of students and the appropriate technology pilot platform to implement the monitoring of myopia of children and adolescents, guide and coordinate relevant parties to implement effective comprehensive public health intervention measures, and take outdoor activities and sports activities as the main starting point to realize the prevention of multiple diseases.

　　2. Pay attention to process and effect evaluation. Disease control institutions at all levels should regularly carry out students’ vision monitoring, deeply analyze the monitoring data over the years, and report the main students’ health problems and suggestions found in the monitoring to the local government in time. Based on the practical research method, the transformation and application from theory to practice can promote the implementation and dissemination of intervention actions. Conduct process and effect evaluation, introduce the implementation research framework and theoretical model, such as the process and effect indicators of comprehensive public health intervention for myopia prevention and control and its collection method (Table 4), comprehensively evaluate the accessibility, effectiveness, applicability and sustainability of intervention actions from the individual level and organizational level, and systematically evaluate the implementation effect of comprehensive public health intervention for children and adolescents with myopia.

　　

　　Beijing, April 22 (Reporter’s Common Sense) China Academy of Agricultural Sciences recently revealed that the "Accurate Identification of Rice Germplasm Resources" project of the Ministry of Agriculture and Rural Affairs, led by the Institute of Crop Science of Chinese Academy of Agricultural Sciences, has unearthed 38 excellent germplasm that can be used for breeding with high yield, high quality, disease resistance, stress resistance, suitable for mechanized planting and resistance to false smut, providing resource support for speeding up the sharing and utilization of excellent germplasm resources and the breeding of new rice varieties.

　　Qian Qian, an academician of China Academy of Sciences, said that the project of "Accurate Identification of Rice Germplasm Resources" has achieved remarkable results, but it is still necessary to intensify accurate identification, speed up the exploration of excellent genes, strengthen the protection of intellectual property rights, speed up the transformation of excellent resources into excellent varieties, and cultivate breakthrough new varieties with independent intellectual property rights.

　　It is understood that the protection and utilization of wild rice germplasm resources in China is being strengthened. The National Wild Rice Germplasm Resources Garden Project, led by the Institute of Agricultural Sciences of China, is located in Yazhou District, Sanya City. It is expected to be completed in June this year. After completion, the resource conservation capacity will reach 40,000 copies, and the annual appraisal and evaluation will be more than 1,000 copies.

1905 movie network news On October 13th, Jackson Yee was invited to attend an offline meeting of a brand as a spokesperson. Not only did I interact with fans on the spot, but I also shared the new skills I got in college. "After going to college, I like campus life more and love learning more."

Jackson Yee appeared in the brand activities in a dark green suit, with tough tooling style elements showing youthful temperament, strong retro charm of corduroy texture, and a touch of Shakespeare-style youthful spirit captured in a trance, handsome without losing style, and simple and capable modeling is very mature.

As a millennial generation, Jackson Yee entered the society earlier than her peers. When asked, "What do you think about work and life?" He said: "There will be a lot to accumulate in work, and more involvement in your life may be more helpful to your work." For the role that has been played at present, the role that is far away from his life and has multi-level changes in his heart is relatively more challenging. So now I will want to study hard at school, concentrate on honing my acting skills and prepare for a better role in the future.

　　BEIJING, Aug. 31 (Zhongxin Finance reporter Zhang Ni) On the 30th, the micro-signal of "Merck China" announced that the new indication of its nine-valent human papillomavirus vaccine (nine-valent HPV vaccine) had been approved by National Medical Products Administration, China, and this approval marked the expansion of Merck’s nine-valent HPV vaccine to women aged 9-45 in China.

　　As soon as the news came out, it attracted great attention from the outside world. Merck’s vaccine was approved for listing in China in 2018, but at that time its applicable age group was women aged 16-26. "Being too old to be vaccinated" has always been a pain point for many women.

　　Then, the age range of vaccination has been broadened. Can people who have already been vaccinated with bivalent or tetravalent vaccines be vaccinated with nine-valent vaccines again? What is the effect after vaccination?

　　What are the functions of nine-valent HPV vaccine?

　　What is the function of nine-valent HPV vaccine? According to the information released by China Center for Disease Control and Prevention, the vaccine is suitable for preventing the following infections or diseases caused by HPV types contained in the vaccine:

　　One is the infection caused by HPV6, 11, 16, 18, 31, 33, 45, 52 and 58;

　　Second, precancerous lesions or atypical lesions caused by the above nine HPV types, including cervical intraepithelial neoplasia (CIN) grade 2/3, cervical adenocarcinoma in situ (AIS) and cervical intraepithelial neoplasia (CIN) grade 1;

　　The third is cervical cancer caused by HPV16 types 16, 18, 31, 33, 45, 52 and 58.

　　What are the main differences between bivalent, tetravalent and nonavalent vaccines, and how to choose them?

　　The main difference between bivalent, tetravalent and nonavalent HPV vaccines is that they contain different HPV types. Bivalent HPV vaccine contains L1 proteins of HPV types 16 and 18, tetravalent HPV contains L1 proteins of viruses 6, 11, 16 and 18, and nonavalent HPV contains L1 proteins of viruses 6, 11, 16, 18, 31, 33, 45, 52 and 58.

　　However, all three vaccines can target the above-mentioned high-risk HPV, prevent HPV-related diseases, and all can fight HPV16 and 18 infections, and the effect is very significant. Compared with bivalent HPV vaccine, tetravalent HPV vaccine can also prevent genital warts caused by HPV6 and 11, and the nine-valent HPV vaccine will increase the proportion of preventing cervical cancer from 70% to 90%.

　　I have already vaccinated bivalent and tetravalent vaccines, can I still fight for nine?

　　At present, people are most concerned about whether bivalent and tetravalent vaccines can be vaccinated in the future. Is it necessary?

　　In this regard, CDC has said that there is no clinical data to support the interchange of nine-valent HPV vaccine with other HPV vaccines. The World Health Organization’s position paper on HPV vaccine has no preference for three vaccine recommendations.

　　From the public health point of view, bivalent, tetravalent and nonavalent vaccines can provide considerable immunogenicity and protective efficacy in preventing cervical cancer (mainly caused by HPV16 and HPV18). According to the existing conditions, it is possible to inoculate any of the three HPV vaccines.

　　According to the instructions of the nine-valent HPV vaccine, if someone wants to vaccinate the nine-valent HPV vaccine after three doses of the four-valent HPV vaccine, they can only be vaccinated at least 12 months later, and the inoculation dose is three doses.

　　Can I get a bivalent or tetravalent vaccine after one or two shots?

　　China CDC has previously introduced that in 2016, the Advisory Committee on the Implementation of Immunization Strategy (ACIP) recommended that if the vaccination procedure was started with tetravalent or bivalent HPV vaccine, the remaining doses could be replaced with nine-valent HPV vaccine to complete the whole vaccination procedure, but according to the World Health Organization’s 2017 position paper on HPV vaccine, the information about the safety, immunogenicity or effectiveness of the interchangeable use of the three HPV vaccines is very limited. These vaccines are different in characteristics, components and indications; In addition, the instructions for the use of tetravalent and nonavalent HPV vaccines also specifically pointed out that there is no clinical data to support the interchangeable use of nonavalent HPV vaccines with other HPV vaccines.

　　Therefore, in areas where multiple vaccines can be selected, efforts should be made to unify vaccination procedures and use the same vaccine for each dose.

　　Vaccination with nine-valent vaccine will not cause diseases caused by HPV?

　　No vaccine can achieve 100% protection.

　　All HPV vaccines can provide a high level of protection against types 16 and 18 (about 70%). HPV vaccine also provides some cross protection for some types that are not included in the vaccine.

　　Nine-valent HPV vaccine will increase the proportion of preventing cervical cancer from 70% to 90%. However, because it fails to cover all high-risk HPV types, nine-valent HPV vaccine cannot prevent all HPV-caused infections or diseases 100%. Cervical cancer screening after vaccination should be carried out as usual.

　　Who is not suitable for nine-valent HPV vaccine?

　　Severe allergic reaction to any active ingredient or adjuvant in HPV vaccine is contraindication. Those who have symptoms of hypersensitivity after vaccination should not be vaccinated again. (End)

　　[Car maintenance] Friends who have a car must know that it is a natural thing to buy a new car for decoration. In addition to traditional decorations such as film mats, it is an accessory that many people choose. Even if the owner does not install it in the end, it must be entangled.

　　In fact, there are always two voices about whether or not to install the fender. One is that it can play a protective role, and the other is that it will affect the sinking of the engine when the vehicle has an accident. In addition, there are many kinds of fender in the market, and how to choose it is also a puzzle that many car owners encounter. So today we will talk about the engine fender.

●　　Why do you need to install a guard?

　　From the point of view of protecting the engine, due to the silt rolled up by the wheels in daily driving and the snow water brought up in rainy and snowy weather, the exposed parts in the chassis will be corroded, which will affect the service life.

　　In addition, the road conditions in China are really "rapidly changing". Maybe the road was fine yesterday, but today a big hole is pulled out to start repairing it, and all kinds of bricks, tiles and construction equipment are everywhere. If you don’t pay attention, the chassis of the car may be in close contact with the big stones. If you are lucky, the chassis will be fine, and if it is serious, the engine or gear will be broken and damaged. The cost of replacing these parts is not small.

●　 Can the original factory bring its own guard board?

　　Judging from the models currently on sale, it seems that there are not many models with fenders on the original car. The so-called self-contained fender of individual models is only an extension of the lower edge of the front bumper. If the engine can be mostly covered, it can be used normally. If the engine cannot be completely covered and the material is very thin, it is difficult to play a protective role. Therefore, many car owners have to choose to install or reinstall engine guards, and businesses have also found business opportunities from the vast demand.

●　 Will there be any disadvantages in installing guard plates?

　　As many people worry, at the beginning of the car design, for safety reasons, the engine will sink in the event of a major collision to avoid personal injury caused by the engine moving back to the cabin. However, if the fender is installed, many people are worried that the sinking of the engine will be affected at the critical moment, thus increasing the hidden danger of personal injury, which has become the biggest reason for many people to give up installing the fender. In principle, everyone’s concern is not unreasonable.

Voice-over: What is engine sinking technology?

　　Some models are designed with "the design of engine sinking during collision". If the engine fender is installed, the engine sinking will be blocked by the fender in the event of a traffic accident, and the sinking position may not be enough, which will affect safety. Of course, the engine guard protects the engine. And who is the engine sinking design to protect?

　　Some friends say it is to protect pedestrians, but this understanding is incorrect. When a car hits a pedestrian, the force generated is usually not enough to cause the displacement of the engine. The design of engine sinking is to let the engine sink when the force generated by the collision is enough to cause the longitudinal displacement of the engine, that is, to squeeze the cab occupant, so as to avoid or reduce the damage of the engine to the cab occupant. Generally speaking, the condition of engine sinking is a frontal collision plus a certain speed (about 40km/h). If it is a side collision, the engine will not sink.

　　In addition, when the vehicle is running, the engine will generate high temperature. If the fender is installed, the air permeability and heat dissipation will be affected to some extent, which is one of the disadvantages after installing the fender.

●　 Should the guard be installed or not?
　
　　As the name implies, the engine guard plate protects the engine. When a car runs on some roads with large road undulations, the height difference of the road undulations exceeds that of the engine bottom shell, which may cause damage to the engine oil pan and then damage the engine.

　　In fact, the engine guard is not something you often rely on or use. You can’t be sure when you will use it, but it will definitely save you a lot of money when it works. Cars can’t just drive on straight roads forever, and even experienced "old drivers" can’t guarantee that they won’t scratch the bottom of the car through bad roads. Installing the engine guard can minimize this damage to the maximum extent.

　　Moreover, some models are designed with reserved openings for installing engine guards, so it can be understood that they have solved the contradiction of "collision and sinking", so from my personal point of view, it is still necessary to install guards.

　　In addition, we also visited some experts in the industry. They said that in the daily driving process, the erosion of sediment and snow water will really affect the vehicles, and the rubbing of the chassis and the slightly serious bottoming are also common. If you don’t pay attention, it will affect or hurt the vehicles. In order to better protect the vehicles, it is necessary to install engine guards.

　　However, the situation that everyone is worried about does exist, so it is necessary to choose the fender products suitable for their own models from the material, and try to give consideration to safety and vehicle protection.

　　Speaking of this, our conclusion is that it is still necessary to install the engine guard, but the choice of the material of the guard is very particular, which is also a key point we want to express below!

●　 Types of guard plates

　　At present, there are many kinds of fender products on sale in the market, which can be divided into four categories in terms of materials: steel, reinforced resin and hard plastic. What are their advantages and disadvantages and what kind of models are suitable for use? We will introduce them one by one. In addition, we also show the prices of several mainstream family car engine guards in Taobao, Auto Parts City and 4s shop for reference.

　　1: Steel plate

　　At present, the steel plate material is the most selected by car owners. First of all, it is cheap. Relatively speaking, the price of the steel plate material is around 200 yuan, and the price is easily accepted by the majority of car owners. Another obvious advantage is that it is hard. The sand and stones rolled up by the tires in daily driving pose no threat to him at all, and even the occasional bottoming will never cause damage to him. Even the serious bottoming is only a slight variation, which is irrelevant for normal use, so many people will choose it.

　　However, the disadvantage of this product is also obvious. The biggest drawback lies in the weight. The weight of twenty or thirty kilograms will inevitably have some impact on the fuel consumption. In addition, the steel plate will only be deformed and not easy to break in a serious accident, which will not only affect the safe sinking of the engine in the event of an accident, but also have the hidden danger of damaging the engine first because of the deformation of the steel plate in the collision, so it is indeed beneficial and harmful.

　　Purchase suggestion:The price of steel plate guard is moderate, and the strength of steel plate is high. Although the weight of twenty or thirty kilograms is really not light, it will not have a great impact on fuel consumption. For those people who travel in cities, it is quite worth recommending. However, if your car often needs to run at high speed, it is recommended not to choose such products. After all, accidents at high speed are generally more serious than those in urban areas, and the disadvantages that affect engine sinking may be taken into account.
