The National Health and Wellness Committee held a regular press conference in Beijing on June 5 to introduce the progress and effectiveness of eye health work in China.

In 1999, the World Health Organization and the International Association for the Prevention of Blindness launched the "Vision 2020" global initiative, with the mission of eliminating avoidable blindness (cataract, trachoma, river blindness, child blindness, low vision and ametropia) on a global scale by 2020, and reversing the trend that avoidable visual injuries may double from 1990 to 2020. China is the first country in the western Pacific to launch the "Vision 2020" action. Since then, the core strategy and objectives of the "Vision 2020" action initiative have been integrated in the formulation of the 11th and 12th Five-Year plans for preventing and treating blindness. At the World Health Assembly in 2013, after the resolution "Universal Eye Health: Global Action Plan 2014-2019" was passed (still a part of the "Vision 2020" action initiative), the country formulated the "Thirteenth Five-Year National Eye Health Plan (2016-2020)" according to the requirements of the new resolution and the overall requirements of building a healthy China and deepening the reform of the medical and health system.

The three core strategies of "Vision 2020" have been fully incorporated into our national defense blind treatment and eye health work: disease control combined with primary health care, human resource development, infrastructure construction and appropriate technology application.

Governments at all levels in China vigorously promote the prevention and treatment of blindness, constantly improve the national, provincial (autonomous regions and municipalities directly under the Central Government) and municipal management systems for prevention and treatment of blindness and the prevention and treatment network of eye diseases in counties, townships and villages, and ensure the accessibility of eye health services at the grassroots level through the construction of the prevention and treatment network. In addition, the work mode of preventing and treating blindness has changed from a single work of preventing and treating blindness to multi-faceted eye health management. At present, more attention is paid to moving forward the gateway and sinking resources, bringing primary eye care into primary health care, bringing ophthalmic diseases into chronic disease management, establishing eye health files, tracking and following up eye care and other long-term mechanisms. The prevention of blindness in China adheres to the government-led, multi-sectoral cooperation and the participation of the whole society. Through the overall planning and policy guidance of the government, the academic groups’ technical advantages, the participation of private hospitals and the active participation of social organizations, a model of eye disease prevention and treatment suitable for China’s national conditions has been formed, providing comprehensive, fair and accessible eye health services for the people.

Cataract is the first blinding eye disease in China.

Cataract is the first blinding eye disease in China. Through all-round long-term efforts, such as developing free cataract treatment project, realizing full coverage of medical insurance and improving the level of ophthalmology service in county-level medical institutions, the number of cataract operations per million people in China has increased from 83 in 1988 to 2205 in 2017, an increase of nearly 27 times. The surgical coverage rate of cataract patients has increased to 62.7%, and the goal that the number of cataract operations per million people in China should reach more than 2,000 by the end of 2020 proposed in the "Thirteenth Five-Year National Eye Health Plan" has been achieved ahead of schedule. In recent years, the state has promulgated a series of policies on promoting the construction and development of medical complexes, promoting the construction of graded diagnosis and treatment system, and comprehensively improving the comprehensive diagnosis and treatment capacity of county-level hospitals. The ophthalmic service capacity of county hospitals in China has been further improved. At present, about 90% of counties in China have ophthalmic medical institutions, and about 90% of them can independently carry out cataract surgery.

Our government actively promotes the early screening and early treatment of childhood blindness.

The proportion of children’s blindness in the total number of blind people is low, but because children are in the early stage of their life cycle, the number of years of disability life lost and the time of disability is long, children’s blindness often brings great burden to families and society. In 2006, the second national sampling survey of disabled people showed that the sampling ratio was 1.93%, the number of children aged 0-6 was 51,328, and there were 193 cases of visual disability, with a visual disability rate of 3.76‰. Over the years, the Chinese government has been actively promoting the early screening and early treatment of blindness in children. Among them, the incidence of retinopathy of prematurity has dropped from 20.3% in the 1990s to 10.8% in 2005, and the blindness rate has dropped significantly. In 2004, after the publication of "Guidelines for the Prevention and Treatment of Oxygen and Retinopathy in Premature Infants", a screening system was basically formed in Beijing, Shanghai, Guangzhou, Shenzhen and other places, which was under the responsibility of an eye center and jointly operated by several neonatal intensive care units. In 2013, in order to improve the quality of children’s health care, and further standardize the contents, methods, processes and assessment of children’s health care services in related fields, the state issued the Notice on Printing and Distributing the Technical Specifications for Children’s Eye and vision care (Wei Ban Fu She Fa [2013] No.26). In 2019, the state issued the "Notice on Doing a Good Job in Eye Care and Vision Examination for Children Aged 0-6", demanding that the establishment and improvement of the residents’ electronic health record information system be accelerated, and the electronic management of the vision health records of children aged 0-6 should be realized as soon as possible.Ensure that the contents related to children’s vision health records in children’s health records of 0-6 years old are completely, accurately and smoothly extracted when children enter school, and handed over to educational institutions in time. In addition, statistical indicators such as the number of children aged 0-6 who have eye care and vision examination, the number of children aged 6 who have vision examination, and the number of children aged 6 who have poor eyesight have been added to the Annual Report on Health Care and Health of Children under Seven. The coverage of eye care and vision examination for children aged 0-6 years and the establishment of electronic files of vision health have been included in the assessment system, and it is required that the annual coverage of eye care and vision examination for children aged 0-6 years will reach over 90% from 2019.

Until the early 1980s, the rehabilitation of low vision was still a blank in China. In 1983, Beijing Tongren Hospital set up the first low vision clinic in China, which filled the gap in the rehabilitation of low vision in China. In 1991, China incorporated the rehabilitation of low vision into the Outline of the Eighth Five-Year Plan for the Disabled in China. Since then, until the Thirteenth Five-Year Plan, the China Disabled Persons’ Federation has made the rehabilitation of low vision one of its key tasks. Through the establishment of the low vision rehabilitation department, training personnel, developing and supplying visual AIDS, and popularizing knowledge, it has trained a large number of low vision rehabilitation professionals and trained hundreds of thousands of parents of children with low vision. According to the National Plan for the Prevention and Treatment of Blindness (2012-2015), all provincial rehabilitation institutions for the disabled have established "low vision rehabilitation centers" to strengthen the service capacity building of low vision rehabilitation centers. Establish the production and supply service network of low-vision AIDS to improve the quality of life of low-vision patients. In 2013, the State issued the Notice on Printing and Distributing Technical Specifications for Children’s Eye and vision care, which clearly stipulated that newborns should be screened for eye diseases regularly after birth, so as to reduce the occurrence of children’s low vision from the source. By 2020, China has initially established a relatively complete service network covering urban and rural areas, and a policy system has been formed in various places to guarantee basic assistive devices services for patients with low vision.The service ability and service status of fitting visual AIDS have been improved, and the adaptation rate of basic assistive devices for disabled people and disabled children with needs has reached over 80%. It can be predicted that under the overall planning of the national health administrative department and the China Disabled Persons’ Federation, through the joint efforts of the whole society, especially professional and technical personnel, China will gradually form a complete and formal evaluation and rehabilitation system to help patients with low vision improve their quality of life and participate in social life.

The number of ophthalmologists in China is estimated to have reached 40 thousand.

The number of ophthalmologists in China was 19,100 in 2003, and now it is estimated that the number has reached 40,000, which is more than twice that of 2003. As early as 2014, there were 1.13 ophthalmologists in every 50,000 people in China, which has exceeded the WHO requirement that there should be one ophthalmologist in every 50,000 people in a well-off country. In 2018, the number of doctors with cataract surgery ability in China was 13,835, 2.33 times that of 2000 (5,939). The number of full-time nurses in ophthalmology has also increased significantly, from 16,100 in 2003 to 50,000. In addition, the proportion of middle and senior ophthalmologists and the ratio of ophthalmologists to doctors and nurses are gradually becoming reasonable. The number of optometrists increased from 1487 in 2006 to 6218 in 2018, a fourfold increase. The number of ophthalmic medical service institutions has increased from more than 4,000 in 2006 to more than 6,000 today, an increase of more than 50%. The number of ophthalmic beds has increased from more than 40,000 in 2000 to more than 130,000 in 2018, a threefold increase.

Trachoma is no longer a public health problem that harms our visual health.

Through the long-term investment and efforts of the China Municipal Government, the patriotic health campaign of the whole society, the implementation of a series of measures such as environmental improvement and the promotion of SAFE strategy, the improvement of economic level and medical level, the state’s investment in rural medical construction and medical insurance, the public health conditions and medical conditions have been greatly improved, and the accessibility of antibiotics for trachoma patients has been greatly improved. In 2014, China achieved the goal of eliminating blinding trachoma proposed by WHO. On May 18th, 2015, it was officially announced at the 68th World Health Assembly: In 2014, China met the requirements of WHO to eradicate blinding trachoma, and eliminated blinding trachoma ahead of schedule. Trachoma is no longer a public health problem that harms our visual health. In 2019, the World Health Organization certified the work of eliminating blinding trachoma in China according to new procedures and standards.

The prevention and treatment of uncorrected ametropia has become an important part of eye health work in China.

屈光不正中的近视是世界范围内发病率最高且年龄跨度最大的眼健康问题，其中高度近视视网膜病变在致盲原因中占相当高的比例，未矫正屈光不正的防治已成为我国眼健康工作的重要内容。2018年下半年，国家卫生健康委员会同教育部、民政部组织开展了2018年全国儿童青少年近视调查工作。2019年4月29日，国家卫生健康委员会举办新闻发布会，介绍2018年儿童青少年近视调查结果。调查结果显示，2018年全国儿童青少年总体近视率为53.6%。其中6岁儿童为14.5%，小学生为36.0%，初中生为71.6%，高中生为81.0%。近年来，党中央、国务院高度重视儿童青少年近视防控工作，近视防控已成为国家战略。2016年至2019年，连续4年将全国“爱眼日”的主题聚焦在儿童青少年的近视防控。为做好近视的防治工作，2018年6月5日，国家卫生健康委员会召开专题新闻发布会，介绍儿童青少年科学防控近视情况，同时发布了《近视防治指南》《弱视诊治指南》和《斜视诊治指南》三部指南。2018年8月28日，习近平总书记再次就儿童青少年近视问题作出重要指示，强调全社会都要行动起来，共同呵护好孩子的眼睛，让他们拥有一个光明的未来。为贯彻落实习近平总书记关于近视问题的重要指示批示精神，切实加强新时代儿童青少年近视防控工作，2018年8月30日，教育部会同国家卫生健康委员会、体育总局、财政部、人力资源社会保障部、市场监督管理总局、国家新闻出版署、广播电视总局八部门制定了《综合防控儿童青少年近视实施方案》（以下简称《实施方案》）。《实施方案》不仅明确了家庭、学校、医疗卫生机构、学生、政府相关部门应采取的防控措施，还明确了八个部门防控近视的职责和任务。2019年10月，国家卫生健康委员会疾控局组织制定并印发了《儿童青少年近视防控适宜技术指南》，指导科学规范开展防控工作，提高防控技术能力。全国防盲技术指导组组织编写的《儿童青少年近视防治科普100问》，对近视防治中的疑问和误区，给出了科学解释。目前，在全社会已营造了儿童青少年近视防控“政府主导、部门配合、专家指导、学校教育、家庭关注”的良好氛围。

With the great attention of the party and the government, the ophthalmology medical and health undertakings have developed rapidly through various joint efforts. The results of two epidemiological surveys of blindness and visual impairment in nine provinces and cities in 2006 and 2014 showed that the prevalence of blindness and moderate and severe visual impairment in China decreased by 37.8% and 15.4% respectively according to the assessment of daily life vision. According to the best corrected vision, it decreased by 37.6% and 27.2%. It is estimated that only among people over 50 years old, the number of blind people in China has decreased by more than 700 thousand, and the number of patients with severe visual impairment has decreased by more than 500 thousand.

At present, the biggest challenge for eye health is the increasing population and aging.

With the promotion of national defense blindness, the improvement of national economic level, the change of people’s lifestyle and the change of population structure in China, the spectrum of blinding eye diseases has changed greatly. The main blinding eye diseases have changed from infectious eye diseases of trachoma in the past to metabolic and age-related non-infectious eye diseases, mainly cataract, keratopathy, retinal diseases, ametropia, glaucoma and amblyopia. The biggest challenge facing China’s eye health at present is the increase of population, especially the increasing aging. By 2019, China’s population over 60 years old has reached 253.88 million, accounting for 18.1% of the country’s total population, and the elderly population is still increasing. The increase in the number of elderly people means that the number of patients with age-related eye diseases is increasing, including ametropia and cataract, which are the main burden of eye diseases in China. In addition, the common blinding eye diseases, including glaucoma, macular degeneration and other fundus diseases, are also age-related eye diseases, and the prevalence rate in the elderly population is much higher than that in young people. These are still the challenges faced by eye health work in China and the focus of eye health work in the future.

除了推动我国自身眼健康事业的发展，我国在防盲与眼健康领域加强国际交流与合作，践行我国全球卫生战略。全国防盲技术指导组整合全国防盲资源，启动的集流行病学调查、专业培训、医疗和健康教育为一体的“光明行”项目中，除了我国老少边困及高原地区的4万余名白内障患者受益，该项目还从2008年开始，跨出国门，在亚太地区的朝鲜、柬埔寨、蒙古国、老挝、越南、孟加拉国、巴基斯坦等国家及地区开展公益活动。2010年“光明行”走入非洲，在津巴布韦、马拉维、赞比亚和莫桑比克等开展白内障复明活动。2015年12月习近平主席在中非合作论坛约翰内斯堡峰会开幕式上致辞时将“中非公共卫生合作计划”作为未来三年同非方重点实施的“十大合作计划”之一予以提出。2015年国家卫生健康委出台的《推进“一带一路”卫生交流合作三年实施方案（2015-2017）》中也明确将开展“光明行”眼科义诊活动列为卫生发展援助的重要内容之一。至今，中国已在40多个国家开展“光明行”活动，其中十多个国家是多次活动，帮助数万名白内障患者重见光明。

"Guangmingxing" not only provides free cataract surgery for local people, but also donates advanced ophthalmic surgery equipment and instruments and medicines. It also provides students with vision screening, donates glasses, and carries out complicated fundus diseases and glaucoma surgery. Academic lectures and clinical teaching have been held in the local area, and an "Ophthalmology Cooperation Center" has been established with relevant countries to conduct long-distance consultation on eye diseases by using the Internet and expand various forms of technical exchanges and cooperation. At the same time, we should pay attention to personnel training and organize local doctors to go to China for training. China’s internationalization of public welfare for the prevention of blindness has brought light to the people of the aided countries, fully demonstrated China’s actions and contributions in building a community of human destiny and countries along the Belt and Road, and also became an important force in China’s diplomacy, further promoted international exchanges and cooperation in health, and enhanced China’s voice and influence in regional and global multilateral health governance mechanisms.

With the change of lifestyle, social development and aging population, the spectrum of ophthalmic diseases in China has undergone major changes. According to the National Health China 2030 Program, we should integrate eye health into general health, formulate our eye health plan, and formulate the 14 th and 15 th eye health plan according to our national conditions. Change the unbalanced regional allocation of ophthalmic resources in China, promote balanced development, shift the treatment of blinding eye diseases to disease prevention and control, pay special attention to the sinking of major blinding eye disease prevention and control technologies, strengthen the construction of primary ophthalmology and ophthalmology teams, and continue to improve the construction of China’s three-level blindness prevention system. It is necessary to continue to promote the training and promotion of appropriate technologies that can prevent and control blinding eye diseases, and move the gateway forward to reduce the incidence and increase the control effect. When the technology is mature, we should promote the screening of eye diseases based on artificial intelligence technology to achieve early detection and early treatment of blinding eye diseases, and try our best to bring the screening of common blinding eye diseases into the chronic disease management system under the premise of China’s economic conditions.

Myopia of children and adolescents has become the main cause of vision damage in China.

Myopia of children and adolescents has become the main cause of vision damage in China. We should resolutely implement the national implementation plan on myopia prevention and control to achieve the goal of myopia prevention and control of children and adolescents in China. For the evaluation of cataract surgery, we should not only consider the quantity, but also evaluate the quality, pay attention to the important index of cataract surgery coverage, formulate the prevention and control index of cataract surgery according to the national conditions, and moderately relax the indications according to the level of social and economic development. In addition, in terms of commonly used ophthalmic equipment and technology, we should vigorously promote localization and completely change the current situation of relying heavily on imported equipment and technology. Breakthroughs have been made in common technology and neck sticking technology. Through scientific popularization, we will enhance people’s understanding of the basic knowledge of eye disease prevention and control, improve the awareness rate, enhance people’s awareness of blinding eye disease prevention and control, and incorporate popular science work into the national eye health plan and the national health science popularization plan. Due to the extension of life expectancy, the increase of the total population, the acceleration of the aging process of the population, and the continuous improvement of people’s demand for eye health, the prevention and treatment of eye diseases in China is still an arduous task, and the primary eye care work still needs to be strengthened, and the concept of healthy living of like eyes needs to be further strengthened.

Li Yanhong, Chairman and CEO of Baidu Company (photo by CCTV reporter Li Wenliang)

　　Cctv news(Reporter Luo Chuan Li Wenliang Li Wenxue Tang Shiying) On December 3rd, the 4th world internet conference opened in Wuzhen, Zhejiang. Li Yanhong, chairman and CEO of Baidu Company, delivered a speech at the sub-forum that afternoon. He believed that the Internet had no demographic dividend, and it was replaced by a technology dividend. In the next few decades, technological innovation represented by artificial intelligence will continue to promote the development of the digital economy.

　　The theme of this conference is "Developing Digital Economy and Promoting Open Sharing — — Work together to build a community of cyberspace destiny. " As soon as Li Yanhong took the stage during his speech, he said humorously: "The first few people didn’t have PPT. I think PPT would be more clear if there were dry goods." It attracted a laugh from the field.

　　Li Yanhong said that the growth rate of Internet users in China was above 50% 10 years ago, but it has actually reached about 6% today, which means that the demographic dividend of the Internet is gone. But there is also the driving force for growth, that is, artificial intelligence. Today, artificial intelligence is in a very early stage of development, much like the growth of the Internet in China more than a decade ago.

　　The demographic dividend is gone, and we still have a technological dividend, that is, technological innovation represented by artificial intelligence, which will continue to promote the development of the digital economy in the next few decades. Algorithm, computing power and data are the three growth drivers of artificial intelligence. In the future, the main driving force for the development of digital economy in China will be artificial intelligence, which will develop at a very fast speed.

　　In the past, Internet companies were basically software-oriented, but today they need a strong combination of software, hardware and services in order to be effective.

　　Li Yanhong took the automobile industry as an example. The automobile industry has been an old industry for hundreds of years. But today, because of the development of artificial intelligence technology, it will not only affect the car factory, but also affect many upstream and downstream industries, such as taxi service providers, chip manufacturers and vehicle manufacturers. Many upstream and downstream companies will benefit from it, or they will be threatened by the development of artificial intelligence technology. The automobile industry will undergo tremendous changes in a hundred years.

　　The promotion of artificial intelligence technology to the real economy and all walks of life is obvious. Li Yanhong believes that from finance to real estate, from education to medical care, from logistics to energy, every industry will change because of technological innovation, and it is expected that artificial intelligence will bring constant surprises to each of us.

　　Recently, the General Office of the Ministry of Education issued the Notice on Further Strengthening the Sleep Management of Primary and Secondary School Students (hereinafter referred to as the Notice), further emphasizing the need to ensure adequate sleep time for students and refining relevant management measures. The "Notice" requires that students’ sleep monitoring and supervision should be strengthened, students’ sleep status should be included in the physical health monitoring and education quality evaluation and monitoring system, included in the scope of daily supervision and the supervision and evaluation of the government’s performance of educational duties, and a supervision and reporting telephone or network platform should be set up to ensure that the requirements are in place and effectively ensure students’ good sleep.

　　We should fully improve our understanding of the importance of sleep health.

　　The Notice puts forward three "important times". The first is the necessary sleep time. Primary school students should sleep for 10 hours a day, junior high school students should sleep for 9 hours and senior high school students should sleep for 8 hours. The second is the school schedule. Class starts at 8: 20 in the morning in primary schools and 8: 00 in middle schools. At the same time, it is emphasized that schools should not require students to arrive at school in advance, and necessary lunch breaks should be guaranteed if conditions permit. The third is bedtime at night. Pupils are generally not later than 21: 20, junior high school students are generally not later than 22: 00, and senior high school students are generally not later than 23: 00. At the same time, guide parents and students, make schedules for students’ work and rest, promote autonomous management, work and rest regularly, and go to bed on time. Only by controlling the school schedule and students’ bedtime at night can students’ necessary sleep time be effectively guaranteed.

　　Lv Yugang, director of the Department of Basic Education of the Ministry of Education, pointed out that schools can manage the morning classes. The more important time is bedtime at night. Some bad living habits, such as watching mobile phones, playing computers and indulging in the Internet, affect students’ bedtime. Whether you can sleep at night depends on the students’ self-management ability and the guidance, cooperation and consultation between parents and students. In this process, we should strengthen the education of students, strengthen the guidance of parents, and strive to ensure that the bedtime at night can be achieved.

　　Zhu Dongbin, deputy director of the Department of Basic Education of the Ministry of Education, said that places and schools with conditions should guarantee students the necessary lunch break. We also encourage all localities and schools to explore all kinds of good experiences and practices that help students sleep according to the actual situation and school facilities. Sleep is a big event, and we should be able to reach a consensus that we should not lose big because of small things, let alone give up the basics.

　　Jiang Fan, secretary of the Party Committee of Shanghai Jiaotong University School of Medicine, director of the Center for Diagnosis and Treatment of Children’s Sleep Disorders, and head of the Children’s Sleep Study Group of the Sleep Medicine Committee of the Chinese Medical Doctor Association, said: The majority of primary and secondary schools, teachers, parents and students should fully raise their awareness of the importance of sleep health, and enhance their understanding of the requirements of sleep time required by different age groups and healthy sleep habits. According to the Notice, the length of sleep students should get every day is consistent with the internationally recognized recommended length of sleep. This requirement is implemented on individuals, and parents also need to master individual differences. Primary school students need 9-12 hours of sleep every day, and middle school students need 8-10 hours. Teachers and parents can strengthen communication with their children, work out schedules suitable for individual students together, and at the same time, they can know whether they sleep well or not from the aspects of children’s mental state and self-feeling, and make adjustments to the schedules according to the actual situation.

　　Sacrificing sleep time for study can’t be exchanged for improving academic performance.

　　In view of the external factors affecting students’ sleep, the Notice puts forward three "interruption mechanisms", requiring homework, off-campus training and games to make way for students’ sleep.

　　The first is the "interruption" of homework, which requires primary school students to basically complete their written homework in school, and middle school students to complete most of their written homework in school. If individual students have not finished their homework by bedtime after efforts, parents should urge them to go to bed on time and not stay up late to ensure adequate sleep. Of course, teachers should conduct targeted analysis, strengthen counseling, and adjust the content and amount of homework if necessary. The second is the "interruption" of off-campus training time, which requires that the off-campus offline training end time should not be later than 20: 30, and the online live training end time should not be later than 21: 00. Homework should not be arranged in any form such as pre-class preparation, after-class consolidation, homework practice, and WeChat group punching. The third is the "interruption" of the game, which requires local education departments to strengthen supervision with relevant departments in accordance with their management authority to ensure that no game services are provided to minors from 22: 00 to 8: 00 the next day.

　　Lv Yugang said that schools should have a sound homework management mechanism, and all subject groups should co-ordinate homework, so as to grasp a reasonable amount of homework and improve the quality of homework. Students should not be allowed to finish their homework during recess when they should go out for activities and jump around the playground, or during the lunch break. Schools and teachers should strengthen the guidance for students to complete their homework, especially to help students with learning difficulties, and increase the intensity of counseling and answering questions so that students can complete their homework within the specified time.

　　Lu Haifeng, director of the Education and Sports Bureau of Qidong City, Jiangsu Province, reminded schools to avoid the thinking mode of split thinking and binary opposition, and make efforts to properly handle several groups of relationships. The first is the relationship between "sleeping less" and "sleeping late" and "getting up early". According to the requirements of the Notice, schools should reasonably determine the schedule of work and rest, enhance the soft power in the publicity of work and rest, and enhance the hard power in the implementation of work and rest, and do not artificially require students to arrive at school in advance, and do not artificially occupy students’ school time. At the same time, they should be flexible and flexible in strictly implementing work and rest, for example, properly resettle individual students who arrive at school in advance due to special family circumstances; The second is the relationship between "less sleep" and "more homework" and "difficult homework". Schools should make great efforts in classroom research and win the light burden of schoolwork with the high efficiency of classroom; Pay attention to homework management and win the light load of homework with the high quality of design; The third is the relationship between "sleeping well" and "sleeping well" and "growing well". Schools should face students face to face, educate students to understand the importance of adequate sleep and develop good sleep habits. Heart-to-heart with parents to guide parents to be the guarantors of their children’s adequate sleep; Join hands with the society and participate in the governance of off-campus training institutions as much as possible to reduce the academic burden of students.

　　At the same time, Jiang Fan said that parents should take appropriate restrictions on children’s use of electronic products, and at the same time, they should set an example and consciously maintain a good work and rest, so that children can clearly understand the importance of sleep and develop a good habit of maintaining regular work and rest independently. Their team research shows that sacrificing sleep time for study can not bring about improvement in academic performance, but will cause extensive damage to executive function and affect the academic performance of children and adolescents. (Guangming Daily reporter Yan Xiaoyan)

　　BEIJING, March 14 (Xinhua) Recently, the Key Laboratory of Big Data Mining and Knowledge Management of the Chinese Academy of Sciences released the White Paper on Online English Education for Children in China in 2017. According to the report, online English education for children in China is spreading its influence around the world, covering 35 countries and regions around the world. Except for China, Japanese, Canadian and American have the largest number of young students who use the services of educational enterprises in China.

　　In the domestic market, first-tier cities such as Beishangguangshen and Shenzhen have become the main force in the online children’s English education market. The three major brands have divided 80% of the domestic market, and VIPKID has a 55% market share; Domestic students tend to be younger, with an average age of about 6 years old. Most parents are willing to spend more than 10,000 yuan a year for this, and 70% parents are willing to choose North American foreign teachers with pure accents and lively teaching.

　　The data also shows that the total daily class hours of online children’s English education in China have exceeded 100,000. From this calculation, parents in China saved 146 million hours in total, effectively solving the pain point of parents’ time-consuming and labor-intensive transportation of their children to class. In terms of teaching staff, there are currently more than 30,000 foreign teachers in North America providing online English teaching services to students around the world, with an average teaching experience of 7.5 years. All of them have bachelor’s degrees or above, and many of them have ivy league backgrounds, including Columbia University, Duke University, Harvard University, Brown University and Stanford University.

　　Dr. Zhong Yunqin, Key Laboratory of Big Data Mining and Knowledge Management, Chinese Academy of Sciences, believes that the follow-up survey in recent years shows that the extensive online education service model is gradually losing its appeal and its business growth is obviously limited; The high-quality personalized Internet education platform pays more attention to the inherent development law of education, and creatively combines new educational concepts, teaching models, artificial intelligence, big data and other technical means to better meet the needs of users in the new era for personalized education. The global rise of domestic online education brands represented by VIPKID caters to this trend and explores new ideas for future educational innovation.

　　The average age of online students is 6 years old, and the number of people in East China accounts for over 30%.

　　The combination of the Internet and traditional education has given birth to a brand-new business scene. Teachers and students are no longer bound by geographical constraints, and students may connect with excellent educational resources around the world without leaving home. At present, the number of paid students on the VIPKID platform exceeds 200,000, covering 35 countries and regions around the world. Japan, the United States and Canada are the three countries with the largest number of overseas students on this platform. Generally speaking, online education has shown strong portability and is becoming an important means for children to learn English all over the world.

　　From the domestic market, first-tier cities such as Beishangguangshen and Shenzhen have become the main force in the online children’s English education market, and the three major regions of North China, East China and South China, which radiate from this, account for 81% of the overall market. Among them, the number of students in East China accounts for the highest proportion, with a share of 36%. North China and South China followed closely with 27% and 18% respectively. Compared with other regions, parents in coastal and economically developed areas are more receptive to online education mode and more willing to cultivate their children’s English ability from an early age.

　　According to the market survey, the Chinese Academy of Sciences shows that the domestic online children’s English education market is still in an early stage after only four years of development. In terms of market share, the top three companies at present are VIPKID, 51Talk and vipJr, which account for more than 80% of the market, of which VIPKID accounts for 55% of the domestic market; In terms of the number of foreign teachers, there are more than 30,000 foreign teachers working on the VIPKID platform, which exceeds the total number of foreign teachers of all other online education brands in China.

　　In major cities, the number of VIPKID students in Beijing, Shanghai, Shenzhen, Hangzhou and Chengdu occupies the top five. This is roughly consistent with the search distribution results of "VIPKID" in Baidu Index. It is worth noting that the students in two quasi-first-tier cities, Hangzhou and Chengdu, are growing rapidly, pushing Guangzhou, which ranked fourth in 2016, to sixth place. Cities such as Nanjing, Wuhan, Dalian and Chongqing also entered the TOP10.

　　At present, children’s English learning in China tends to be younger. From the perspective of urban distribution, the average age of students in first-tier cities is generally around 6 years old, and the average age of students in second-tier cities has slightly risen to 6.5 years old. The survey also shows that more and more parents begin to consider English education before their children are 3 years old.

　　Online mode helps parents in China save 146 million hours a year.

　　Driven by the deepening economic and cultural exchanges between China and foreign countries, the maturity of internet education technology and application, and the reform of English teaching, the online English education model for children has been recognized by more and more families and parents. Among them, parents in first-tier cities such as Beishangguang have fully realized that online education is an effective way to quickly improve their children’s English listening and speaking level, and the related cognition of parents in second-tier cities has also been significantly improved. In contrast, parents in third-and fourth-tier cities are still relatively vague about the concept of Internet education, and the market needs more patient cultivation.

　　The data shows that users in the online children’s English market have strong spending power, and middle-class families with an annual income of 200,000-1 million account for 58%. Most parents said that they would spend more than 10,000 yuan on their children’s English education every year. Despite the high cost, most families still think that online English education has remarkable learning effect and high cost performance.

　　According to the survey data of a large number of parents by Chinese Academy of Sciences, the phenomenon that many parents passively choose Asian foreign teachers is changing under the previous insufficient supply. At present, 73.6% of parents prefer to choose foreign teachers in North America for three reasons: foreign teachers in North America have purer accents and more lively teaching methods, and North America is the first choice for their children to study abroad. 22.1% parents tend to choose British or Australian foreign teachers, while only 4.3% are willing to choose Asian (Philippines, Vietnam and Indonesia) foreign teachers.

　　In online children’s English learning, after-class evaluation is a very important part of the evaluation of learning effect. At present, the number of foreign teachers on the VIPKID platform exceeds 30,000, and the total number of evaluations by users after class exceeds 5 million, and each foreign teacher receives an average of 167 evaluations. Foreign teachers with five-star praise are more favored by parents, and foreign churches with bad reviews are quickly eliminated by the market. A tripartite feedback mechanism between parents, North American foreign teachers and online platforms is taking shape. In terms of specific dimensions, "paying attention to pronunciation", "being patient and friendly" and "being good at guiding" are the three evaluation keywords that parents are most concerned about, and the number of evaluations related to each keyword exceeds 1 million.

　　The rise of online English education mode highlights many disadvantages of traditional offline mode. According to the survey of offline traditional mode, 85% parents complain that it takes time and effort to pick up and drop off their children, which is particularly prominent in first-tier cities. Many parents spend far more time on picking up and dropping off their children than the class hours themselves. 68% of parents think that the level of offline foreign teachers is uneven and the choice space is extremely limited; 61% parents think that offline mode is not conducive to systematically understanding their children’s learning progress; 49% parents think that there is too little interaction in offline large class mode; 28% of parents said that their children are not interested in learning in offline institutions.

　　Online education allows more and more children to enjoy North American English education without leaving home, which saves parents a lot of time. The survey shows that parents in big cities spend an average of more than 2.5 hours on picking up and waiting for a class for their children, and the average time spent in small and medium-sized cities is about 1.8 hours.

　　At present, VIPKID has 100,000 online courses every day, which exceeds 50% of the total online courses of the same kind in China. Calculated by saving 2 hours per class, online mode saved about 146 million hours for parents in China. Even according to the walking distance, it saves parents in China nearly 730 million kilometers a year, which is equivalent to 18,250 laps around the equator of the earth. Switching to car transport calculation will help China families save about 650,000 tons of gasoline consumption every year.

　　The data shows that when children adapt to the online mode, 82% of online children’s English learners complete their classes independently without their parents’ company. At the same time, parents are more willing to learn about their children’s learning at any time with the help of classroom video playback and real-time class monitoring system. More than 87% parents have used the course playback function within one month, including 13% parents who work in different places or travel, who have used the real-time class monitoring function within one month.

　　Because the online children’s English learners are generally young, and the teaching pays more attention to the improvement of English comprehensive ability such as expression, parents’ feedback on the effect is lagging behind. VIPKID class data shows that in the first five classes, parents think that the effective curve grows more slowly; With the deepening of the course, the growth rate of the feedback result curve is obviously improved, and the maximum growth rate is ushered in in the 20 th section; Since then, parents’ satisfaction has shown a continuous growth trend.

　　Among the extracurricular reading materials of online children’s English education, excellent picture books are more popular with children. On the VIPKID open class platform, the TOP5 five are all excellent picture books, including popular science, fairy tales, humanities and other topics. In terms of reading habits, it becomes an open class collective "movie-watching day" for parents of students every Friday night.

　　The average teaching experience of foreign teachers in North America is 7.5 years, and the master’s degree is over 30%

　　According to the data of foreign teachers from VIPKID, the foreign teachers in North America engaged in online children’s English education are mainly concentrated in the eastern part of the United States, followed by the central part of the United States, the western part of the United States and the southeastern part of Canada. In terms of specific states, Texas in central China ranks first in the number of foreign teachers, followed by Florida, Utah, Georgia and California, the largest state in the United States.

　　Among the TOP10 cities in North America, Orlando, a city in central Florida, has the largest number of foreign teachers, and Chicago and Houston rank second and third, with a small gap with Orlando. As the sole representative of Canadian cities, Toronto ranks fourth.

　　According to the data of VIPKID foreign teachers, the number of foreign teachers in North America who have been teaching for more than 5 years accounts for 70%, with an average teaching experience of 7.5 years. Among them, foreign teachers with 10-20 years of teaching experience account for 25%, and foreign teachers with more than 20 years of teaching experience account for 7%. In terms of academic qualifications, all foreign teachers in North America have bachelor’s degrees or above, of which 30% are masters and 2% are doctors. From the data of appointment, foreign teachers with longer teaching experience are more popular with parents, and foreign teachers with active expressive force are also deeply loved; It is worth noting that the number of male foreign teachers only accounts for 10% of the total, and the demand for classes is in short supply.

　　The Internet education model has enabled foreign teachers who graduated from top universities in the world to enter China families. The data shows that among the more than 30,000 North American foreign teachers, there are many graduates from American Ivy League and well-known universities, including Columbia University, Duke University, Harvard University, University of Pennsylvania, Brown University and Stanford University. These foreign teachers with prestigious backgrounds cover pedagogy, psychology, special education, literature, sociology and economics.

　　The survey shows that the focus of foreign teachers in North America in the process of online teaching is first to improve their self-skills, followed by a sense of accomplishment and educational public welfare, and finally to improve their income and cross-cultural communication experience. With its mature teacher training system, VIPKID continues to empower foreign teachers, thus becoming the most popular online children’s English education platform for foreign teachers in North China in 2017, and surpassing Amazon to become the first in the list of the most popular telecommuting platforms in the United States, which also highlights the unique attraction of online education in for foreign teachers.

　　The rapid development of online children’s English industry allows foreign teachers to freely choose various teaching platforms. When choosing a teaching platform, foreign teachers in North America first look at the number of students on the platform, followed by the degree of technical stability and whether the course content is easy to teach and learn; In addition, the popularity of the platform and the teaching atmosphere are also important factors affecting foreign teachers in North America. At present, in the major social networking sites in the United States, the popularity of VIPKID far exceeds that of 51Talk and vipJr, which rank second and third.

　　Online mode promotes education and benefits a large number of rural primary schools.

　　The Internet has enabled a large number of high-quality educational resources to cover children in poor areas in China in a short period of time, and various online education platforms in China have launched various public welfare activities. "VIPKID" has been extended to 100 rural schools since it started on September 12, 2017. These schools are located in 21 provinces in China, with Yunnan, Gansu and Guizhou accounting for the largest proportion.

　　Compared with the trend of younger students in cities, English education in rural areas generally started late. According to the 100 rural schools covered by "VIPKID", most rural children’s English education begins after the third grade. The combination of online education and public welfare has enabled more North American foreign teachers to enter rural classrooms. Among the 3,745 students covered by the VIPKID public welfare project, 92% said that they were exposed to foreign teachers for the first time.

　　With the help of online education mode, the plight of weak and limited English teachers in rural schools has been quickly improved. "VIPKID foreign teachers from North America enter the rural classroom" only took one month, and the average completion rate jumped from the initial 78% to over 90%, and some of them have already achieved 100% completion.

　　For rural children, learning English faces many challenges, including the lack of local English teachers, poor English teaching materials and equipment, and parents’ insufficient attention to English education. According to the survey of rural children’s wishes, the number one in rural children’s minds is looking forward to "more foreign teachers’ classes", followed by "more picture books", and "parents pay more attention to my study", and "I can communicate in English" is also at the top of the wish list.

　　The adoption of the Gregorian calendar by our government began in the Republic of China. Therefore, in China, the history of New Year’s Day is less than a hundred years.

　　On January 1, 1912, Sun Yat-sen was sworn in as the provisional president in Nanjing, announcing the establishment of the provisional government of the Republic of China. At the same time, the "Declaration of the Provisional President" was issued, and the time at the end of the declaration was "New Year’s Day of the first year of the Republic of China". This is the first time that the Gregorian calendar has been used in the official proclamation, and it is also the first time that the word "New Year’s Day" with modern significance has been used. Subsequently, Sun Yat-sen ordered that in order to "do summer, it is suitable for farming; From the western calendar, so statistics ",switch to the solar calendar. On January 2, Sun Yat-sen electrified the provinces to change their calendars, and took January 1, 1912 as the beginning of the founding of the Republic of China.

　　From then on, China began to adopt the western calendar, taking January 1 of the Gregorian calendar as the New Year’s Day. Throughout the Republic of China, in fact, in the daily life of our people, the traditional lunar calendar was still used, but the first day of the first lunar month was generally called the Spring Festival. Since then, New Year’s Day and Spring Festival have been divided into two festivals, but New Year’s Day is still often used as a synonym for Spring Festival. For example, in January 1930, when Mao Zedong commanded the Red Army to fight in Jiangxi, he wrote a poem "Dream of New Year’s Day" with the words: "Ninghua, Cleanliness, Naturalization, and the roads are deep and slippery. Where to go today, pointing to Wuyi Mountain. Under the mountain, the red flag is picturesque. " New Year’s Day here means the same as Spring Festival.

　　At the beginning of the Gregorian calendar in China, Lu Xun wrote an article "Habits and Reform", in which he said: "Even the unemployed people in Shanghai and employees of the company lamented, or it was very inconvenient for farmers to cultivate, or it was very inconvenient for seagoing ships to wait for the tide. Therefore, we actually think of farmers in the countryside and boats at sea who have been irrelevant for a long time. This is really like fraternity. "

　　On September 27, 1949, the first plenary session of the China People’s Political Consultative Conference resolved: "The chronology of People’s Republic of China (PRC) adopts the AD chronology method." As a result, the Chinese government has adopted a more thorough method of AD chronology, and all government announcements, statistical reports, newspaper mastheads, etc. adopt the Gregorian calendar. The traditional lunar calendar in China has completely disappeared from official documents except that it is marked behind the Gregorian calendar in the headlines of important newspapers. The New Year’s Day holiday was also stipulated as one of the four legal holidays in China in the "National Holidays and Remembrance Days" adopted at the meeting of the Special Council (now the State Council) on December 23rd, 1949. Today, the calendar year and New Year’s Day festivals have gradually become universal, popular and stable among Chinese people. New Year’s Day and Spring Festival are no longer mixed in appellation. For example, in 1952, President Mao Zedong’s Speech at the New Year’s Day Group Meeting, New Year’s Day here refers to the Gregorian New Year’s Day.

　　New Year’s Day is an international festival, and different nationalities have different stories about the origin of New Year’s Day. It was the ancient Egyptians who first named New Year’s Day. Because of the need to calculate the Nile flood cycle, astronomy and solar calendar in ancient Egypt came into being. 7000 years ago, after long-term observation, the ancient Egyptians found that whenever Sirius rose with the sun, the Nile rose immediately, and it was always about 365 days before the next time. So ancient Egypt took the day when the Nile rose as the beginning of the new year, which was called the "Rising Water New Year". This is about the earliest origin of New Year’s Day.

　　Today’s Gregorian calendar, named after its universal use in all countries in the world, is a kind of solar calendar that people are most familiar with, also known as western calendar, solar calendar and Gregorian calendar. The Gregorian calendar adopts the chronological method, which is calculated from the year when Jesus was born, which is closely related to the prosperity of Christianity. This calendar is saturated with the civilization created by human beings for thousands of years. After learning the essence of the Egyptian calendar, the ancient Romans formulated a more accurate julian calendar during the reign of Julius Caesar. With the expansion of Roman Empire and the spread of Christianity, julian calendar spread all over the world. On March 1st, 1582, Pope Gregory XIII reformed the calendar and decided to adopt the plan of Italian doctor Lirio. In 400 years, the three extra leap years in julian calendar were eliminated, with an average annual length of 5: 49: 12 on 365 days, 26 seconds longer than the return. Although according to this calculation, there will still be an error of one day after about 3000 years, but this accuracy is quite remarkable. This is the origin of the Gregorian calendar we use today, also known as the Gregorian calendar.

　　Due to the influence of Portuguese, Spanish, Dutch, French, British, German, American and other Christian countries in the last 500 years, and because of the relative accuracy of the Gregorian calendar, the calendar method of the year of the AD has been adopted by countries all over the world. As a holiday, New Year’s Day is not comparable to Christmas in the west and Spring Festival in China, but it has become a worldwide holiday because of its secularity and non-religion.

　　Due to the different longitude positions of countries in the world, the time of celebrating New Year’s Day is different in different countries, so the date of New Year’s Day is different. For example, Tonga, an island country in Oceania, is located on the west side of the date line. It is the first place in the world to start a new day, so it is also the first country in the world to celebrate New Year’s Day. Western Samoa, located on the east side of the Japanese date line, is the place where a new day begins at the latest in the world, so it is also the country that celebrates New Year’s Day at the latest in the world. According to the Gregorian calendar, China is the 12th country in the world to start the New Year.

　　At the same time, based on the differences between the southern hemisphere and the northern hemisphere, New Year’s Day in countries in the northern hemisphere happens to be winter, or the wind is cold, or the snow is fluttering, or the winter sun shines brightly … while countries in the southern hemisphere welcome the New Year in summer, and their feelings of celebrating the holidays are very different.

　　
In addition to the above reasons, due to the different cultural traditions of various ethnic groups, the date of New Year’s Day in some countries is not January 1 of the Gregorian calendar. For example, Iran implements the Islamic calendar, and celebrating the New Year means celebrating the arrival of spring. Its season and month are not fixed, usually in the late March of the Gregorian calendar. India starts from October 31st every year as the New Year, which lasts for five days, and the fourth day is New Year’s Day. The traditional Thai New Year’s Songkran Festival (Songkran is a Sanskrit transliteration), also known as the Songkran Festival, is from April 13th to 16th every year in the Gregorian calendar.

Hi, this is a ride,

A fashionista who focuses on dressing up and exclusive to your beauty!

No matter how the fashion style changes, it is the most suitable for us, or the most classic practical items. This item may not look so outstanding, but it will definitely make you feel comfortable and keep you in a good mood all day.

Known as the wild king in the wardrobe, you won’t be disappointed in how you wear it. So I brought these today.Practical modeling of simple foundation, make it easier for you to wear.

Since we want to take stock of the practical series for everyone, let’s give you a simple analysis. The first piece of advice for you here,Choose a solid color system.

Because the solid color system is so versatile, no matter how you wear it, you can hardly make mistakes. Even if it is popular color, the solid color system is often easier to control than the collision color system, which reduces the difficulty of daily collocation.

Since you have chosen the basic single product of solid color system, it is not recommended that you choose the same color matching scheme here. Even the same color matching scheme should have different levels, that is to say, low-key and simple, but there should be a little bright spot.

So with the same color, it is better to change it.Homochromatic systemWear, wear different colors in the same color.Hierarchical feelingWear a fashion style.

Nothing is more versatile than black in autumn and winter. With the matching of the same color of black, we can use dark gray to set off, which can not only wear a sense of hierarchy, but alsoIt won’t be too boring..

Although it is more suitable to wear dark colors in autumn and winter (after all, dark colors can really be visually slim), it does not mean that light colors are not feasible.

Light colors can become very fashionable and slim.Especially in some overlapping collocation, white is the key point of collocation, so it is indispensable.

So the second suggestion given here, when using dark color system, can beOverlay light colors,Further creating a layered sense of collocation can not only make the collocation style more temperament, but also make the whole person look fresher and more beautiful, and capture the full rate of return.

Dark color is superimposed with light color to highlight the texture of light color, so it is not necessarily white, but also your favorite popular color.

In the light color department, light brown is recommended by individuals, followed by off-white color. These two colors are definitely beautiful colors to wear. Earth tone’sSteady and elegantShow it on brown. The gentle temperament of white is displayed in beige.

If the above two kinds of collocation can be applied to hearty and easy-to-use, then we can learn the third collocation scheme, which is our advanced collocation scheme today. useMix and match fashion, embellished with practical wear.

Because the collocation of practical series, after all, is the collision of basic models and basic models, so the collocation is a little less personality trend. If you want to be more fashionable, you need to make a little mix and match.

Mix and match design is actually very"exaggeration", is not suitable for daily life, so I suggest you use it here.Small mashupDesign, that is, the advanced choice of basic models.

In general, it is a contrast color design, or an element embellishment is added. For example, the basic version of the suit jacket is transformed into a plaid element, so this is a mix and match design technique. So the mashup is not so complicated, but it has become richer.

In a word, the collocation of practical series is divided into three steps.

Step 1: Try to choose a solid color.Pay attention to layering when matching with the same color system, and choose a layered design that is more suitable for you to create qualified daily wear.

Step 2: Overlap the light color system.Let the matching style have a layered feeling easily, and use the freshness and elegance of light color to create a full return rate.

Step 3: Small Mix and Match Design, add some elements and contrast colors appropriately to enhance the highlights of matching.

I am a hitchhiker. If you are confused, you can write to me privately. You are also welcome to leave a message for discussion! Learn to wear it with the ride, and we will become better and more beautiful people together!
