"Five new Jianyang" are taking off in the butterfly.

I. Background

　　Since the 21st century, with the rapid development of China’s economy and society, people’s work and lifestyle have changed, and the physical activity of residents has decreased significantly. Insufficient physical activity is the fourth independent factor leading to human death. Sports activities have become the most active, effective and economical way of life to enhance the national physique and improve the health level.
　　Our government attaches great importance to the important role of sports activities in strengthening physical fitness and improving health level. In 1995, the State Council promulgated and implemented the Outline of the National Fitness Program; In 2007, the State Council issued "Opinions on Strengthening Youth Sports to Enhance Youth Physical Fitness"; In 2014, the State Council issued "Several Opinions on Accelerating the Development of Sports Industry and Promoting Sports Consumption"; In 2016, the State Council issued the Outline of Healthy China 2030, which made clear arrangements for developing mass sports activities, advocating the new fashion of national fitness and promoting the construction of a healthy China.　　
　　Since the implementation of the National Fitness Program in 1995, China’s mass sports undertakings have developed vigorously, sports administrative departments at all levels have actively implemented the Outline of the National Fitness Program, and the youth sports work has been continuously promoted, and the awareness of sports activities has been significantly enhanced; The average area of gymnasiums and gymnasiums in China is 1.57 square meters, and the proportion of people who regularly participate in sports activities is 33.9%. The forms of sports activities for the elderly are rich and colorful, and the quality of life is improved. According to the data of the sixth census, the average life expectancy in China is 74.9 years. The social atmosphere in which sports activities have become an important means to keep fit has been formed.
　　However, we should be aware that the role of sports activities in strengthening the national physique and improving the health level has not been fully exerted, and there is still a big gap from the requirements of a healthy China. According to relevant national survey data, although the proportion of people who regularly participate in sports activities in China has increased year by year, the overweight rate and obesity rate of residents have also continued to increase, and the changes of indicators such as adolescent endurance, adult muscle strength and endurance, and elderly muscle strength are not optimistic. The incidence of chronic non-communicable diseases such as cardiovascular disease and diabetes is on the rise, and many research results of sports activities in the field of health promotion have not been fully applied to practice. Most residents have great blindness when participating in sports activities. There is still much room for improvement in physical fitness and disease prevention and control. Therefore, it is urgent to issue an authoritative guide to physical fitness activities at the national level to guide residents to engage in physical fitness activities scientifically.
　　According to the actual situation of China residents’ participation in physical fitness activities, the National Fitness Guide systematically summarizes and integrates the relevant national research results in the Tenth Five-Year Plan, the Eleventh Five-Year Plan and the Twelfth Five-Year Plan, and is compiled based on the measured data of China residents’ physical fitness. It mainly includes the effect of physical fitness activities, the test and evaluation of sports ability, the principles of physical fitness activities, the guiding scheme of physical fitness activities and so on.

Second, the effect of physical fitness activities

　　In ancient China, there was a written record of improving human health through introduction. A large number of modern research results have confirmed that regular participation in physical fitness activities can effectively enhance physical fitness, prevent diseases, and improve study and work efficiency.

　　(A) to enhance physical fitness, improve health.

　　Constitution refers to the comprehensive and relatively stable characteristics of human morphological structure, physiological function and psychological factors on the basis of heredity and acquisition. Physical fitness activities can improve the cardiopulmonary function, muscle strength, flexibility, balance and reaction ability of human body, and improve body composition, so as to achieve the effect of enhancing physical fitness and improving health level.

　　1. Improve cardiopulmonary function

　　Cardiopulmonary function is one of the core factors affecting physical fitness and health. Low cardiopulmonary function can lead to an increased risk of premature death. Regular physical activities can improve cardiac contractility and vital capacity, regulate blood pressure, improve blood lipids, have a good impact on cardiopulmonary function, and obviously improve the cardiopulmonary function and health level of teenagers, middle-aged people and the elderly.

　　2. Improve body composition

　　Body composition refers to various substances that make up the body and their proportions, which are generally expressed by body fat content and muscle weight and their ratios. Studies have confirmed that excessive body fat, especially abdominal fat, can induce cardiovascular diseases and metabolic diseases. Physical activities based on aerobic exercise can increase fat consumption, reduce body fat content, increase muscle weight and improve body composition.

　　3. Increase muscle strength

　　Strength training can improve muscle strength and muscle fatigue resistance, promote the growth and development of teenagers, make their physique stronger, prevent symptoms such as waist pain, shoulder and neck pain caused by muscle strength attenuation, improve body balance, prevent the elderly from falling, maintain bone health, and prevent and delay osteoporosis.

　　4. Improve flexibility

　　Flexibility is not only an important sports skill, but also an important activity ability in daily life. Regular traction exercises can improve the elasticity of muscles and ligaments, increase the range of physical activities of teenagers, have beautiful body posture, reduce muscle strain, and prevent and treat joint diseases of middle-aged and elderly people.

　　5. Improve the happiness index

　　Physical exercise is an effective means of psychological intervention. Physical fitness activities can increase people’s sense of pleasure, make people relax, relieve stress, form a good psychological state, get physical and psychological satisfaction, make teenagers full of vitality, middle-aged and elderly people full of vitality, and improve happiness index.

　　(B) prevention and treatment of diseases, improve the quality of life

　　Physical activity can improve the functional level of human organs, enhance the body’s immunity and prevent diseases, especially for chronic non-communicable diseases. Chronic non-communicable diseases, including cardiovascular diseases, diabetes and osteoporosis, are important diseases that endanger the health of Chinese residents. Regular physical activities can effectively control the inducing factors of chronic non-communicable diseases, prevent the occurrence of chronic non-communicable diseases, and at the same time, it is also an effective means to treat chronic non-communicable diseases, improve the quality of life and reduce premature death caused by improper lifestyle and insufficient physical activity.

　　1. Cardiovascular disease

　　The prevalence of cardiovascular disease among Chinese residents is on the rise, and cardiovascular death ranks first among the total causes of death among urban and rural residents. Regular physical activities can reduce the risk factors of cardiovascular diseases, effectively prevent cardiovascular diseases and promote the rehabilitation of patients with cardiovascular diseases by improving heart function and vascular elasticity, lowering blood pressure, reducing inflammatory factors and regulating blood lipids.

　　2. Diabetes

　　Diabetes is one of the common chronic diseases, and type 2 diabetes is the most common. Regular physical activity can regulate glucose metabolism, reduce blood sugar, improve the sensitivity of target cells to insulin, effectively prevent and treat type 2 diabetes, and delay the occurrence and development of complications. Physical activity can enhance the physique of diabetic patients and improve their quality of life.

　　3. Overweight and obesity

　　Overweight and obesity are characterized by weight gain and are usually expressed by body mass index (BMI). Overweight and obesity are related to many chronic diseases, including hypertension, coronary heart disease, diabetes, some cancers and various musculoskeletal diseases. The most effective means to prevent and reduce obesity are physical activity and diet balance. Physical activity is the most active method to prevent and control obesity, which can help obese people control their weight, improve their physiological function, prevent weight rebound after losing weight and reduce the occurrence of chronic diseases related to obesity.

　　4. Osteoporosis

　　Osteoporosis is a bone tissue disease characterized by decreased bone density, changes in microstructure of bone tissue, and increased fracture susceptibility. Physical activity helps to increase bone mass, improve bone structure, slow down the loss of bone mass caused by aging, prevent falls and reduce the risk of osteoporotic fractures by enhancing muscle strength and balance.

　　5. Cancer

　　Cancer, also known as malignant tumor, ranks second among the total causes of death among Chinese residents. Physical activity can reduce the risk of breast cancer, colon cancer, lung cancer, prostate cancer and other cancers, relieve the pain of postoperative treatment of cancer patients, and improve the survival rate and quality of life of cancer patients. The World Health Organization estimates that more than 30% of cancers can be prevented by physical activities.

　　6. Depression

　　Depression, also known as depressive disorder. In recent years, the incidence of depression in China is on the rise. Physical fitness activities can change the chemical composition of the brain, cause good emotional and state responses, effectively prevent depression, and have a positive intervention effect on patients with mild to moderate depression.

　　(C) improve the efficiency of study and work

　　Physical fitness activities can improve people’s cognitive ability and make people concentrate. Regular physical fitness activities can reduce the release of inhibitory neurotransmitters, delay central fatigue, have a good impact on the nervous system, help improve the learning efficiency and academic performance of teenagers, extend the effective working hours of adults and improve work efficiency.

Third, the sports ability test and evaluation

　　Sports ability refers to the ability of the human body to engage in sports activities. The sports ability test and evaluation of this guide includes single sports ability test and evaluation and comprehensive sports ability evaluation. Before engaging in sports activities, the human body should comprehensively test and evaluate the indexes related to sports ability, so as to scientifically formulate personalized sports activities programs. At different stages of engaging in sports activities, we should regularly carry out sports ability tests to objectively evaluate the effect of sports activities and ensure the safety and effectiveness of sports activities.

　　(A) individual sports ability test and evaluation

　　Single exercise ability test includes aerobic exercise ability, muscle strength, flexibility, balance and reaction ability test. The evaluation of individual sports ability adopts a five-point system, with 5 being excellent, 4 being good, 3 being medium, 2 being poor and 1 being poor.

　　1. Aerobic exercise ability

　　Aerobic exercise ability reflects the ability of human body to carry out aerobic exercise for a long time, which is closely related to cardiopulmonary function. Strong aerobic exercise ability indicates good cardiopulmonary function. Good aerobic exercise ability is an important sign of good health. Regular participation in sports activities can maintain and improve the aerobic exercise ability of human body.

　　Maximum oxygen uptake is an important index to evaluate aerobic exercise ability.

　　2. Muscle strength

　　Muscle strength is the ability of muscles to overcome or resist resistance when they are nervous or contracting. Muscle strength test indicators include grip strength, back strength, push-ups, sit-ups, vertical jump test and so on.

　　3. Flexibility, balance and reaction ability

　　Flexibility refers to the range of motion of each joint during physical activity and the elasticity and stretching ability of ligaments, tendons, muscles, skin and other tissues across the joint. Good flexibility can increase the range of motion and reduce sports injuries.

　　② Balance refers to the ability to maintain body posture or control the center of gravity. Balance ability is the basis of static and dynamic activities. Good balance ability can effectively prevent all kinds of injuries caused by falls.

　　③ Reaction ability mainly refers to the ability of the human central nervous system to consciously control the rapid movement of the skeletal muscle system after receiving certain instructions or stimuli, which embodies the coordination between the nerve and the muscle system.

　　(2) Comprehensive sports ability evaluation

　　Cardiopulmonary function is one of the most important factors affecting human health, and aerobic exercise ability is closely related to cardiopulmonary function. Therefore, aerobic exercise ability is ranked first in the comprehensive exercise ability evaluation system, with a weight of 40%.

　　Obesity can induce a variety of chronic diseases and become an important risk factor for public health. BMI is an index reflecting the degree of obesity. In view of the important role of BMI in the evaluation system of physical fitness and health, and its obvious influence on sports ability, BMI is included in the comprehensive evaluation system of sports ability, with a weight of 20%.

　　The calculation formula of BMI is: weight (kg) divided by the square of height (m) [BMI= weight (kg)/height 2 (m 2)]. The normal range of BMI in Chinese is greater than 18.5 and less than 24, with BMI equal to or greater than 24 being overweight and equal to or greater than 28 being obese.

　　Muscle strength is closely related to exercise ability and quality of life, and its weight is 20%. The weights of flexibility, balance and responsiveness are 10%, 5% and 5% respectively.

　　According to the weights and coefficients of different individual sports ability indexes in the comprehensive sports ability evaluation, the comprehensive sports ability score is calculated, and the calculation method is as follows:

　　Comprehensive athletic ability score = aerobic athletic ability score ×8+ muscle strength score ×4+BMI score ×4+ flexibility score ×2+ balance ability score ×1+ reaction ability score ×1.

　　The comprehensive sports ability evaluation adopts four grades: 85 or above is excellent, 75 or above is good, 60 or above is qualified, and less than 60 is poor.

Fourth, the principle of physical fitness activities

　　Engaged in physical fitness activities, we must follow the following principles and develop good habits of physical fitness activities.

　　(A) the principle of safety

　　The principle of safety refers to that in the process of physical fitness activities, it is the primary principle to ensure that sports participants do not appear or try to avoid sports injury accidents. Before starting physical fitness activities, you should have a physical examination, comprehensively evaluate your physical condition and sports ability, and make a physical fitness program suitable for your own characteristics. Make full preparations before physical fitness activities, and do a good job of sorting out and relaxing after physical fitness activities.

　　(B) the principle of all-round development

　　The principle of all-round development means that in physical fitness activities, all parts of the body should participate in sports, so that the functional level of various organ systems can be generally improved, not only to improve cardiopulmonary function and immune ability, but also to improve physical fitness such as muscle strength and flexibility. Therefore, it is necessary to choose physical fitness activities involving the main muscle groups of the whole body to achieve all-round development results.

　　(3) The principle of gradual progress

　　The principle of gradual progress refers to scientifically and gradually increasing the time and intensity of physical fitness activities. The principle of step by step emphasizes that according to one’s adaptability to physical fitness activities, one should gradually increase the exercise load, so as to improve one’s physical function and athletic ability continuously, so as to achieve the best physical fitness activities.

　　(D) the principle of individuality

　　The principle of individuation refers to making individualized exercise and fitness programs according to everyone’s genetic characteristics, functional characteristics and exercise habits. When making an exercise and fitness program, it is necessary to carry out necessary medical examination and exercise ability test in order to understand everyone’s specific situation and make the exercise and fitness program more personalized.

Five, physical fitness program elements

　　To make a plan of physical fitness activities, we should mainly consider three basic elements: the way of physical fitness activities, the intensity of physical fitness activities and the time of physical fitness activities.

　　(A) Physical fitness activities

　　Physical exercise mode is the specific fitness means and methods adopted by physical fitness activists. According to the sports characteristics of different sports fitness activities, sports fitness activities can be classified into five categories: aerobic exercise, strength exercise, ball games, traditional sports in China and traction exercise.

　　1. Aerobic exercise

　　Aerobic exercise refers to the rhythmic periodic exercise in which the main muscle groups of the whole body participate under the condition of sufficient oxygen supply. During aerobic exercise, the main muscle groups of the whole body participate in the work, which can improve the human function in an all-round way and is the most popular way of physical activity at home and abroad. Aerobic exercise is divided into moderate intensity exercise and high intensity exercise. Moderate exercise intensity mainly includes fitness walking, jogging (6 ~ 8 km/h), cycling (12 ~ 16 km/h), mountain climbing, stair climbing, swimming, etc. High-intensity exercise mainly includes running (more than 8 km/h) and cycling (more than 16 km/h). Moderate intensity aerobic exercise has a steady rhythm and is the safest way for middle-aged and elderly people to exercise.

　　People should take aerobic exercise as the basic way of physical activity when doing physical fitness activities, and those who take improving cardiopulmonary function, losing weight, regulating blood pressure and improving blood lipid as the main purposes can choose aerobic exercise as the first choice.

　　2. Strength exercises

　　Strength training refers to the way that the human body overcomes resistance and improves muscle strength. Strength exercises include non-instrumental strength exercises and instrumental strength exercises. Non-instrumental exercises refer to strength exercises to overcome one’s own resistance, including push-ups, vertical jumping in situ, sit-ups, etc. Instrument strength exercise refers to the strength exercise that the human body carries out on various strength exercise instruments.

　　Strength exercises can improve muscle strength, increase muscle volume, develop muscle endurance, and promote bone development and bone health. Teenagers’ strength exercises can obviously improve their physical fitness and make their bodies stronger; After adulthood, with the growth of age, strength exercises should be increased year by year; Strength exercises for the elderly can improve their balance ability and prevent all kinds of accidental injuries caused by physical falls.

　　3. Ball games

　　Ball games include direct physical contact ball games and indirect physical contact ball games. The former includes basketball, football, rugby, hockey, ice hockey, etc. The latter includes volleyball, table tennis, badminton, tennis, gateball and softball.

　　Ball games are interesting, and participants’ interest in sports can be improved through competition and confrontation. Ball games have certain special technical requirements and need good physical fitness as the foundation. Regular participation in ball games can improve the body’s cardiopulmonary function, muscle strength and reaction ability, and adjust the psychological state, which is the first choice for teenagers.

　　4. Traditional sports in China.

　　Traditional sports in China include Wushu and Qigong. Specific forms of activities include Tai Ji Chuan (sword), Mulan Boxing (sword), martial arts routines, Wuqin Opera, Baduanjin, Yijinjing, Six-character Tactics and so on.

　　China’s traditional sports and fitness methods are gentle, soft and rigid, and emphasize the combination of ideas and physical activities, which has a unique health-keeping effect. It can improve the cardiopulmonary function and balance ability of human body, improve the function of nervous system and adjust mental state, and has good safety.

　　People, especially middle-aged and elderly people, whose main fitness purpose is to improve their balance, flexibility and coordination, improve their heart and lung functions and adjust their mental state can choose the traditional exercise and fitness methods in China.

　　5. Pulling exercises

　　Traction exercises include static traction exercises and dynamic traction exercises. Various traction exercises can increase the range of motion of joints, improve sports skills and reduce sports injuries.

　　Static traction includes positive pressure leg, side leg press, shoulder pressing, etc. Dynamic traction includes forward kicking, side kicking, waist swinging, etc. Those who take part in physical fitness activities for the first time should focus on static traction exercises, and gradually increase the content of dynamic traction exercises with the improvement of flexibility.

　　See Table 1 for the fitness effects of different sports activities.

　　Recommend sports activities according to the purpose of sports and fitness;

　　— — Physical exercisers whose main purpose is to improve their physical fitness and strengthen their bodies choose their favorite physical fitness activities that can be adhered to for a long time, such as aerobic exercise, ball games and traditional China fitness exercises.

　　— — Physical exercisers whose main purpose is to improve heart and lung function should choose aerobic exercise, ball games and other physical fitness activities in which the whole body muscles participate.

　　— — Physical exercisers whose main purpose is to reduce weight should choose long-term aerobic exercise. Long-term and moderate-intensity physical fitness activities can increase body fat consumption and reduce fat content. Long-term brisk walking, jogging and cycling are ideal exercise methods to reduce weight.

　　— — Physical exercisers whose main purpose is to adjust their mental state should choose various recreational ball games and traditional China sports such as Tai Ji Chuan and Qigong, so as to relieve their psychological pressure and improve their sleep.

　　— — Sports athletes whose main purpose is to increase muscle strength can choose instrumental strength exercises and non-instrumental strength exercises according to their own fitness needs and conditions. The effect of strength exercises is related to strength load and repetition times. Generally, strength exercises with large load and few repetitions mainly develop muscle strength, while strength exercises with small load and multiple repetitions mainly develop muscle endurance.

　　— — Physical exercisers with the main purpose of improving flexibility can choose various pulling exercises, especially in the preparation and relaxation stages, which can not only save physical exercise time, but also achieve better fitness results. Various aerobic exercises, aerobics, Tai Ji Chuan, Qigong and yoga can improve flexibility.

　　— — Physical exercisers whose main purpose is to improve their balance ability can choose various special balance training methods, including sitting balance ability exercise, standing balance ability exercise and sports balance ability exercise. Tai Ji Chuan (sword), table tennis, badminton, tennis, softball and other sports can also improve the balance ability of the human body.

　　— — Physical exercisers whose main purpose is to improve their reaction ability can choose various ball games, such as table tennis, badminton, basketball, football and tennis, which can improve their reaction ability.

　　See Table 2 for the recommended sports activities according to the purpose of sports and fitness.

　　(B) the intensity of physical fitness activities

　　The intensity of physical fitness activities is an important content of making physical fitness activities plan. The intensity is too small, and there is no obvious fitness effect; Excessive intensity is not only bad for fitness, but also may cause sports injuries.

　　1, the intensity of physical fitness activities.

　　The intensity of physical fitness activities can be divided into three levels: low intensity, medium intensity and high intensity.

　　Low-intensity exercise has little stimulation to the body, and the center rate of exercise process is generally less than 100 times/minute, such as walking.

　　Moderate intensity exercise stimulates the body moderately, and the center rate of exercise process is generally 100 ~ 140 times/minute, such as walking, jogging, cycling, Tai Ji Chuan, tennis doubles and so on.

　　High-intensity exercise can stimulate the body, which can further improve the fitness effect. The sports center rate exceeds 140 times/minute, such as running, fast cycling, fast-paced aerobics and fast mountain climbing, stair climbing, tennis singles, etc.

　　People with good exercise habits and good physique can do high-intensity and moderate-intensity exercise; People with certain exercise habits and good physique can use moderate intensity exercise; People who participate in physical fitness activities or are weak in physique at the beginning can exercise at moderate or low intensity. Physical exercisers can adjust their exercise intensity scientifically according to their own conditions to adapt to individual conditions when implementing the physical fitness program.

　　2. Monitoring the intensity of physical fitness activities

　　The indexes for monitoring the intensity of physical fitness activities include exercise center rate, breathing changes during exercise and self-feeling during exercise.

　　(1) monitoring the intensity of physical fitness activities with heart rate.

　　The greater the intensity of physical fitness activities, the more obvious the body and heart respond to sports stimuli and the faster the heart rate. Generally, the maximum heart rate percentage and the measured heart rate during exercise are commonly used to monitor the intensity of physical exercise.

　　The maximum heart rate refers to the fastest heartbeat frequency that can be achieved during human movement, expressed in beats/minute. There are two methods to measure the maximum heart rate: direct measurement and indirect inference. For direct measurement, it is necessary to adopt incremental load exercise testing in special testing institutions, which requires special exercise testing instruments and equipment.

　　The maximum heart rate of human body is related to age, and the maximum heart rate of normal people can be calculated by the following formula: maximum heart rate (beats/minute) =220- age (year)

　　During physical exercise, the heart rate is 85% or above the maximum heart rate, which is equivalent to high-intensity exercise; The heart rate is controlled in the range of 60% ~ 85% of the maximum heart rate, which is equivalent to moderate intensity exercise; The heart rate is controlled in the range of 50% ~ 60% of the maximum heart rate, which is equivalent to low-intensity exercise.

　　In the process of physical fitness activities, when the measured heart rate reaches more than 140 beats/minute, it is equivalent to high-intensity exercise; The heart rate is in the range of 100 ~ 140 beats/min, which is equivalent to moderate intensity exercise, and the heart rate is lower than 100 beats/min, which is equivalent to low intensity exercise.

　　(2) Monitoring the intensity of physical fitness activities by breathing.

　　Physical fitness activities cause changes in human respiratory frequency and depth, and exercise intensity can be monitored according to the changes in breathing during exercise.

　　Breathing easily: compared with the quiet state, the breathing frequency and breathing depth change little during exercise, and breathing is stable, so you can sing. The exercise heart rate in this breathing state is generally below 100 beats/min, which is equivalent to low-intensity exercise.

　　Breathing is relatively easy: the breathing depth and breathing frequency increase during exercise, and normal language communication can be achieved. The exercise heart rate is equivalent to 100 ~ 120 beats/min, which is a medium and small intensity exercise.

　　Shortness of breath: you can only speak short sentences during exercise, but you can’t fully express long sentences. The exercise heart rate is equivalent to 130 ~ 140 beats/min, which is a moderate intensity exercise.

　　Shortness of breath: it is difficult to breathe during exercise, and you can’t talk in words during exercise. Exercise heart rate generally exceeds 140 beats/min, which is a high-intensity exercise.

　　(3) Monitor the intensity of physical fitness activities with subjective physical sense.

　　Subjective physical feeling during human exercise can be divided into 6-20 grades, with light intensity exercise as easy (grade 9-10), moderate intensity exercise as slightly tired (grade 13-14) and high intensity exercise as tired (grade 15-16).

　　Subjective physical sensation levels are closely related to heart rate. The number of subjective physical sensation levels during exercise is multiplied by 10, which is equivalent to the heart rate during exercise (times/minute). For example, the number of subjective physical sensation levels in exercise is 12, which is equivalent to the heart rate of 120 beats/minute in exercise.

　　Physical exercisers can control exercise intensity through subjective physical feeling. Generally speaking, when doing moderate-intensity aerobic exercise, the subjective physical feeling is relaxed or slightly tired.

　　See Table 3 for the intensity division and monitoring of physical fitness activities.

　　3. Strength training intensity and fitness effect

　　The greater the load weight of strength exercises, the greater the exercise intensity. When doing strength exercises, the maximum repetitive load (RM) is often used to indicate the magnitude of load intensity. Maximum repetitive load refers to the maximum number of strength exercises that can be repeated when a certain load is used in muscle strength exercises. For example, when a person flexes and stretches a dumbbell, the maximum load is 20kg, and it can only be repeated once, then 20kg is the maximum repeated load (1RM) of his dumbbell. If he can repeat the flexion and extension of the load-bearing arm for 8 times at most with a load of 15 kg, then 15 kg is the maximum repeated load (8RM) of his load-bearing arm for 8 times. In non-instrumental strength training, a person can complete 8 push-ups, which is equivalent to 8RM, and so on.

　　Strength training load intensity can be divided into three levels: low intensity, medium intensity and high intensity, and strength training intensity is closely related to fitness effect.

　　High-intensity strength exercises, equivalent to 1 ~ 10rm, each load weight is repeated for 1 ~ 10 times, and each part is repeated for 2 ~ 3 groups, and the interval between groups is 2 ~ 3 minutes. High-intensity strength exercises are mainly used to improve the maximum muscle contraction strength.

　　Moderate intensity strength exercise, equivalent to 11 ~ 20rm, the repetition times of each load weight are 10 ~ 20 times, each part is repeated in 3 groups, and the interval between groups is 1 ~ 2 minutes. Moderate intensity strength exercises can be used to improve muscle strength and increase muscle volume.

　　Low-intensity strength exercise, equivalent to 20RM or above, each load weight is repeated more than 20 times, each part is repeated in 2 groups, and the interval between groups is 1 minute. Low-intensity strength exercises are mainly used to develop muscle endurance.

　　(3) Time for physical fitness activities

　　The time of each physical fitness activity directly affects the effect of physical fitness activities. Exercise time is too short, which has little effect on improving physical function; However, if the exercise time is too long, it will easily cause fatigue accumulation and will not further increase the fitness effect. For people who often participate in physical exercise, the effective physical fitness activity time is 30 ~ 90 minutes every day. In the initial stage of participating in physical fitness activities, the exercise time can be slightly shorter; After a period of physical fitness activities, the body can adapt to sports and can extend the exercise time. Physical fitness activities can be carried out once a day or several times separately, and each physical fitness activity should last for more than 10 minutes.

　　People who are used to physical fitness activities should exercise for 3-7 days a week, with 30-60 minutes of moderate-intensity exercise or 20-25 minutes of high-intensity exercise every day. In order to achieve the ideal effect of physical fitness activities, we should carry out moderate-intensity exercise for more than 150 minutes or high-intensity exercise for more than 75 minutes every week; If you have good exercise habits, and the comprehensive evaluation of exercise ability test is above good, you can do 300 minutes of moderate-intensity exercise or 150 minutes of high-intensity exercise every week, and the fitness effect is better.

Six, the content and arrangement of a physical fitness activity

　　A complete physical fitness activity should include three parts: preparation activity, basic activity and relaxation activity, as shown in Table 4.

　　(1) Preparatory activities

　　Warm-up activities refer to various physical exercises before the start of major physical fitness activities. The main function of warm-up activities is to mobilize the functional potential of heart, lungs, muscles and other organ systems in advance, so as to adapt to the upcoming various fitness activities, obtain the best exercise fitness effect, and effectively prevent acute and chronic sports injuries.

　　The preparation time is generally 5 ~ 10 minutes, which mainly includes two aspects. First, carry out proper aerobic exercise, such as brisk walking and jogging, so as to "warm up" various organ systems of the body and enter the working state in advance; The second is to carry out various traction exercises to increase joint mobility, improve the elasticity of soft tissues such as muscles and ligaments, and prevent muscle injury.

　　(2) Basic activities Basic activities are the main forms of physical exercise, including aerobic exercise, strength exercise, ball games and traditional China sports and fitness methods, and the duration is generally 30-60 minutes. In a physical fitness activity, it is necessary to choose a suitable exercise mode and control the appropriate exercise intensity and exercise time. In the arrangement of physical fitness activities in a week, physical fitness activists can have different physical fitness activities and exercise intensity according to their own situation. See Table 5 for the arrangement of exercise intensity, duration and exercise frequency of different physical fitness activities.

　　(3) Relaxation activities

　　Relaxation activities refer to all kinds of physical activities after the main physical fitness activities, mainly including low-intensity activities such as walking (or jogging) and various pulling exercises. After physical fitness activities, doing some moderate relaxation activities will help to eliminate fatigue, alleviate or avoid some uncomfortable symptoms in the body, and gradually restore the functions of various organs and systems of the body from the state of exercise to the state of quietness. Doing some traction exercises is beneficial to improve the flexibility of the body.

Seven, different stages of physical fitness activities.

　　(A) the initial physical fitness program

　　People who have just participated in physical fitness activities have less exercise load, and the duration of each physical fitness activity is relatively short, so that the body gradually adapts to the exercise load and the exercise ability is gradually improved. At the beginning of the physical fitness activity plan, you should choose the physical fitness activity mode that you like or conform to the fitness purpose. There should be a comfortable sense of fatigue after exercise, which basically disappears the next day after exercise.

　　At the beginning of physical fitness activities, the principle of increasing exercise load is to increase the daily exercise time, then increase the number of days of exercise per week, and finally increase the intensity of exercise.

　　The initial period of physical fitness activities is about 8 weeks, and the specific plan is as follows:

　　— — Exercise mode: moderate intensity aerobic exercise, ball games, China traditional exercise mode and flexibility exercise.

　　— — Exercise intensity: 55% of the maximum heart rate, gradually increasing to 60%.

　　— — Duration: Exercise for 10-20 minutes each time, and gradually increase to 30-40 minutes.

　　— — Exercise frequency: 3 days/week, gradually increasing to 5 days/week.

　　See Table 6 for an example of the initial physical fitness program.

　　(2) Medium-term sports fitness program

　　After 8 weeks of physical fitness activities, the human body basically adapts to the exercise load at the initial stage of exercise, and its physical function and exercise ability are improved, so it can enter the middle stage of physical fitness activities. At this stage, continue to increase the intensity and time of exercise, and gradually increase the time of moderate-intensity aerobic exercise to 150 minutes or more per week, so that the body can adapt to moderate-intensity aerobic exercise. The medium-term physical fitness activities last about 8 weeks, and the specific plan is as follows:

　　— — Exercise mode: maintain the initial mode of physical fitness activities; Increase strength exercises appropriately.

　　— — Exercise intensity: aerobic exercise intensity gradually increases from 60% ~ 65% of the maximum heart rate to 70% ~ 80% of the maximum heart rate; Anaerobic exercise can be arranged once a week, and the strength exercise uses a load of more than 20RM, which is repeated 6 ~ 8 times.

　　— — Duration: 30 ~ 50 minutes for each exercise; If anaerobic exercise is arranged, exercise for 10 ~ 15 minutes each time; 1 ~ 2 strength exercises once a week, 6 ~ 8 kinds of muscle strength exercises each time, and 1 ~ 2 groups are repeated for 5 ~ 10 minutes.

　　— — Exercise frequency: 3 ~ 5 days/week.

　　At this stage, the physical fitness program is basically fixed, and gradually transitions to a long-term and stable physical fitness program. See Table 7 for examples of mid-term physical fitness activities.

　　(3) Long-term physical fitness program

　　When the physical function reaches a higher level and good habits of physical fitness activities are formed, a long-term stable physical fitness activity plan suitable for one’s own characteristics should be established. Long-term and stable physical fitness activities should include at least 200-300 minutes of moderate-intensity exercise or 75-150 minutes of high-intensity exercise every week; Carry out strength exercises 2 ~ 3 times a week, and pull exercises no less than 5 times. The specific scheme is as follows:

　　— — Exercise mode: maintain the exercise mode in the middle stage of physical fitness activities.

　　— — Exercise intensity: moderate intensity exercise is equivalent to 60% ~ 80% of the maximum heart rate, and high intensity exercise reaches more than 80% of the maximum heart rate; Strength exercises are performed with a load of 10 ~ 20 rm and repeated for 10 ~ 15 times; All kinds of pulling exercises.

　　— — Duration: 30-60 minutes of moderate intensity exercise each time, or 15-25 minutes of high intensity anaerobic exercise, or alternating moderate and high intensity exercise; 8 ~ 10 kinds of muscle strength exercises, each repeated 2 ~ 3 groups, each time for 5 ~ 10 minutes of stretching exercises.

　　— — Exercise frequency: exercise for 5 ~ 7 days/week, and high-intensity exercise should not exceed 3 times per week.

　　See Table 8 for examples of long-term physical fitness activities.

　　A few days ago, the General Office of the Hubei Provincial Party Committee and the General Office of the Provincial Government issued the "Implementation Opinions on Further Improving the Scientific and Accurate Prevention and Control of COVID-19 Epidemic Normalization", and issued a notice requesting all localities and departments to conscientiously implement it in light of the actual situation.

　　The full text of the "Implementation Opinions on Further Improving the Scientific and Accurate Prevention and Control of COVID-19 Epidemic Normalization" is as follows:

　　In order to implement the Party Central Committee’s decision-making and deployment on the prevention and control of normalized epidemic situation, and implement the spirit of "Guiding Opinions on Doing a Good Job in the Prevention and Control of COVID-19 Epidemic Situation" (Guo Fa Dian [2020] No.14) of the State Council Joint Prevention and Control Mechanism, combined with the actual situation of epidemic situation prevention and control in our province, the following opinions are put forward.

　　I. General requirements

　　Thoroughly implement the spirit of the series of important speeches and important instructions of the Supreme Leader General Secretary on epidemic prevention and control, do a good job in ideological preparation and work preparation for long-term normalization prevention and control, always tighten the string of epidemic prevention and control, and resolutely overcome paralysis, war-weariness, luck and relaxation. We will continue to pay close attention to the work of "internal defense rebound, external defense output and strict prevention of input", pay more attention to prevention and control according to law, scientific prevention and control, and precise prevention and control, and improve and implement the normalized prevention and control mechanism of timely detection, rapid disposal, precise control and effective treatment. Tightening territorial responsibility, departmental responsibility, unit responsibility, personal and family responsibility, re-investigating prevention and control loopholes, re-reinforcing prevention and control priorities, and re-implementing prevention and control requirements, guarding your own doors, keeping an eye on your own people, and doing your own thing well, ensuring that the epidemic situation does not rebound, the achievements of epidemic prevention and control will be wasted, and striving to win the "double victory" of epidemic prevention and control and economic and social development.

　　Second, the work measures

　　 (A) adhere to the prevention first, and build a prevention and control barrier.

　　1. Continue publicity and education. Strengthen the publicity of laws and regulations on the prevention and control of infectious diseases, prevention knowledge and prevention and control guidelines, guide the public to firmly establish the consciousness of "individual is the first person responsible for health", and develop sanitary habits and lifestyles such as wearing masks scientifically, washing hands frequently, keeping social distance, strengthening ventilation and disinfection, and comprehensively improve the health literacy of urban and rural residents and improve their self-protection ability.

　　2. Vigorously promote the patriotic health campaign. We will prevent the gateway from moving forward and the center of gravity from sinking, continue to promote the patriotic health campaign, continue to do a good job in urban and rural environmental sanitation management, comprehensive improvement of environmental sanitation in key places such as farmers’ markets and residential areas (villages), vector control, etc., do a good job in cleaning and disinfecting public areas in residential quarters, and establish and improve a long-term environmental sanitation management mechanism.

　　3. Effectively strengthen the guidance on epidemic prevention and control. Provincial disease prevention and control professional institutions should issue prevention and control guidelines in a timely manner according to the epidemic situation in different periods and the characteristics of different people, different industries and different places. City and county-level disease prevention and control professional institutions should, according to the characteristics of the local epidemic situation, strengthen the guidance on prevention and control of resumption of work, business, and classes, scientifically standardize public prevention and control behavior, improve the working mechanism of mass prevention and control, and build a complete epidemic prevention and control barrier.

　　(2) Insist on strengthening the foundation at the grass-roots level and keeping an important defense line in the community.

　　4. Enrich the power of community prevention and control. Select the best and strengthen the secretaries of grass-roots party organizations, promote the professionalization and specialization of community workers, and establish and improve the community normalization prevention and control work team in which party member, community workers, grass-roots medical personnel, police, property managers, volunteers, various community autonomous organizations and residents widely participate. Strengthen the linkage among counties (cities, districts), streets (towns) and communities (villages), further clarify the division of responsibilities, adhere to the command and dispatch of grass-roots party organizations, implement various prevention and control requirements, and build a community governance pattern of co-construction, co-governance and sharing under the guidance of party building.

　　5. Accurately implement community control. Streets (towns and villages) should strengthen the inspection and supervision of community prevention and control work, continue to do a good job in policy propaganda, prevention and control guidance and problem supervision and rectification work, and earnestly keep the first line of defense in the community. Wuhan should continue to strengthen and improve the management and control of residential areas, coordinate the implementation of management and control forces, focus on strengthening the management and control of old residential areas, open residential areas, "three noes" residential areas, urban villages, urban-rural fringe areas, dormitories, rented houses and other areas, and insist on scanning health codes, checking body temperature, wearing masks and recording strangers’ information for people entering and leaving, and adjust the management and control measures in a timely manner according to the epidemic situation. Low-risk areas in other cities and States outside Wuhan can optimize and adjust community management measures in light of local conditions, and continue to do a good job in the investigation and control of key populations. All localities should establish a working mechanism that combines prevention and control with emergency management under normal conditions.

　　6. Strengthen grid management. Make full use of health codes, incorporate epidemic prevention and control into the key content of grid management, do a good job in information collection, epidemic prevention and control investigation and epidemic information publicity of community personnel, strengthen the management of key groups such as fever personnel, overseas and high-risk areas who come to and return from Hubei, asymptomatic infected people, cured and discharged patients, close contacts, people with difficulties in life, floating population, etc., so as to achieve full coverage and no omissions, ensure efficient and accurate information collection, and ensure strong and orderly control of key personnel. Improve the community sharing mechanism of epidemic information in health, entry and exit departments, and improve the pertinence and accuracy of information collection and epidemic investigation of grid staff.

　　(C) Adhere to the role of "checkpoints" and hold the first pass of the hospital.

　　7. Strengthen the pre-inspection triage system and closed-loop management of fever clinic. Medical institutions at or above the second level and township health centers should set up fever clinics and triage points in strict accordance with the norms, and play the role of "checkpoints" for hospital early warning, warning and alarm. All fever clinics should strictly implement the procedures of receiving, screening and referral, and carry out rapid screening of nucleic acid, antibody, CT and hemogram for fever patients after entering the fever clinic, so that ordinary patients can be treated symptomatically, suspected patients can be isolated for observation, and confirmed patients can be transported in time. At the same time, the closed-loop management of fever patients should be established simultaneously, and the closed-loop management of epidemic reporting and epidemic adjustment should be carried out simultaneously for suspected and confirmed patients.

　　8. Strengthen the prevention and control of hospital sensation and the protection of medical personnel. Strictly implement the prevention and control system of nosocomial infection, standardize the setting of clean areas, polluted areas, semi-polluted areas, medical staff passages and patient passages in hospital fever clinics and infectious areas, and implement the provisions of "double triage and double buffering" in general outpatient and emergency departments. Strengthen the monitoring of nosocomial infection, do a good job in personal protection of medical staff, strictly manage visits and escorts, set up safety protection facilities, strengthen ventilation and disinfection of wards, and standardize the disposal of medical wastes. On the basis of doing a good job in nucleic acid screening for medical staff, the nucleic acid screening for accompanying staff and workers should be implemented.

　　9. Implement patient treatment and personnel isolation measures. Cities and States should designate designated hospitals for the treatment of critically ill patients in COVID-19, and treat critically ill patients in accordance with the principles of centralized patients, experts, resources and treatment. Counties (cities, districts) designate more than one designated hospital in COVID-19 and one medical observation point for asymptomatic infected people, designate centralized isolation points that can accommodate more than 200 people as centralized isolation places for close contacts and entry personnel, and reserve enough medical resources such as beds, medical personnel and materials to deal with possible epidemics.

　　10. Do a good job in rehabilitation treatment and management of discharged patients. All localities should integrate professional forces, do a good job in rehabilitation and psychological counseling of discharged patients in the form of family doctors signing services, purchasing services and volunteering services, and strengthen psychological crisis intervention.

　　(four) adhere to focus, pay close attention to the implementation of prevention and control measures.

　　11. Do a good job in prevention and control of key places. On the premise of implementing prevention and control measures, open shopping malls, supermarkets, hotels, restaurants and other places in an orderly manner; Open parks, tourist attractions and sports venues by making an appointment or limiting the flow; Open indoor venues such as libraries, museums and art galleries in an orderly manner; Can hold all kinds of necessary meetings, exhibitions and other activities. According to the development of the epidemic situation, Wuhan can gradually, steadily and orderly open indoor theaters, chess and cards rooms, amusement halls, Internet cafes, dance halls, bars, KTV, indoor swimming pools, closed places or some areas of stadiums and gymnasiums with poor ventilation conditions such as using underground space according to the situation; Low-risk areas in other cities and states outside Wuhan can decide the opening of relevant places on their own according to the overall assessment of epidemic prevention and control.

　　12. Strengthen the prevention and control of key institutions. Continue to implement closed management of pension institutions, welfare homes, prisons and mental health medical institutions, and do a good job in risk prevention. Implement prevention and control measures such as personnel access management, personnel protection, health monitoring, disinfection, etc., and all new entrants will be isolated for 14 days and tested for nucleic acid. Visitors should take personal protective measures and encourage non-contact visits such as videos. If there are medical service institutions such as infirmary and nursing station in the old-age care institutions, they shall not serve outside the scope of medical licensing services. If a medical institution holds an old-age care institution or is adjacent to it, it shall carry out cross-infection assessment according to the requirements of zoning management of medical institutions, and take necessary control measures if there are risks.

　　13. Highlight the prevention and control of key populations. Guide the elderly, children, pregnant women, the disabled, medical personnel, patients with severe chronic diseases and other key groups to do personal protection, and carry out psychological counseling, care and assistance. Strengthen the assistance of vagrants and beggars, and find that fever personnel take timely control measures.

　　14. Strengthen campus prevention and control. Implement the system of "daily report" and "zero report" on the health status of faculty and students. Do a good job in health tips, health management, classroom ventilation, disinfection, etc., and implement prevention and control measures such as morning and afternoon (evening) check-up of school attendance, tracing and registration of the cause of absence due to illness. All localities should equip each school with full-time or part-time professional health personnel in accordance with the provision of 1 professional health personnel for every 600 students. Wuhan has implemented the "1+2" prevention and control cooperation mechanism with one school doctor, one community general practitioner and one disease control staff. Students, faculty and staff in the school campus continue to implement protective measures to wear masks and keep social distance, and adjust the regulations on wearing masks in a timely manner according to the epidemic prevention and control situation. Students in schools in low-risk areas in other cities and States outside Wuhan may not wear masks, and teachers may not wear masks when teaching.

　　15 to prevent the import of overseas epidemic. Implement the "push" of immigration information — Comparison — Screening — Feedback "information closed loop and the" transportation intervention "of overseas people from Hubei — Port quarantine — Classified transshipment — Centralized isolation — Community prevention and control "closed loop of the whole process management, strengthen the management of overseas people coming to Hubei. All persons who have lived abroad for 14 days before coming to Hubei will be tested for nucleic acid, among whom the confirmed patients, suspected patients, suspected fever patients, close contacts and asymptomatic infected persons will be classified and disposed of on the spot according to the prevention and control regulations, and all other persons will be kept under centralized medical observation for 14 days in the first entry city and will be included in the local community (village group) prevention and control system.

　　(5) Persist in standing by and resolutely deal with sudden outbreaks.

　　16. Strengthen monitoring and early warning. Strictly implement the reporting system of infectious diseases, integrate the monitoring information of disease control, medical care, medical insurance and medicine, improve the early warning mechanism, define the dynamic early warning indicators, procedures, grades and methods, and establish a highly sensitive perennial monitoring and early warning system in COVID-19. Implement monitoring and reporting of symptoms such as abnormal body temperature in communities, units, public places and ports. Improve the ability of screening, investigation and disposal of infectious diseases in primary medical and health institutions.

　　17. Rapid linkage reaction. After finding confirmed cases, suspected cases, asymptomatic infected persons and clustered cases, counties (cities, districts) should immediately organize, direct and dispatch the epidemic disposal work; Disease control institutions and public security departments should complete the work of flow adjustment and epidemic point sealing and control within 24 hours; Street (township) in conjunction with the first aid, medical and other institutions responsible for the transfer of patients, asymptomatic infected persons and close contacts, the implementation of isolation treatment or centralized medical observation. Strengthen the joint prevention and control of epidemic-related areas, notify the infectious sources and close contacts in the field, and strictly manage them on the spot according to the principle of territoriality.

　　18. Accurate and powerful disposal. Adhere to the principle of early, small, strict, practical and classified disposal, implement the "four early" measures of early detection, early reporting, early isolation and early treatment, quickly determine the epidemic point, epidemic area, spread range and population, implement strict closure management, and control the epidemic situation to a minimum. In case of sporadic epidemic, the building and ward where the case is located shall be designated as the epidemic point; If there is a cluster epidemic, the community and natural village (group) where the case is located shall be designated as the epidemic point (a larger area may be designated as the epidemic area); In case of epidemic spread, the community and administrative village where the case is located shall be designated as epidemic areas.

　　(six) adhere to strict testing and screening, strengthen the management of asymptomatic infected people.

　　19. Expand the scope of nucleic acid screening. Implement relevant funds and policy guarantees in accordance with state regulations, further increase the intensity of nucleic acid testing, expand the scope of testing, and do everything that should be tested, willing to be tested, and able to be tested. On the basis of ensuring the full coverage of key groups such as expatriates, teaching staff, medical staff, public transport service personnel, employees in public places and relevant personnel in special places, as well as people with difficulties in living in rental houses, public officials with wide social contacts, universities and primary and secondary school students, and ensuring the full coverage of key areas such as old communities, open communities, "three noes" communities, villages in cities, urban-rural fringe areas, collective dormitories and rental houses, Wuhan combines prevention and control. On the basis of continuing to do a good job in the testing of teaching staff and medical personnel, other cities and States outside Wuhan will determine the screening scope by themselves according to local conditions. Xiaogan, Huanggang, Ezhou and other cities should do a good job in nucleic acid testing for students who have resumed classes.

　　20. Improve the ability of nucleic acid detection. All tertiary general hospitals, centers for disease control and prevention, qualified specialized hospitals, secondary hospitals and independent medical laboratory in the province should further strengthen laboratory construction and improve the ability of nucleic acid detection. It is necessary to strictly carry out daily supervision, ensure the quality of testing, optimize services, improve efficiency and reduce prices. In 2020, each county (city) must have at least two nucleic acid testing laboratories. Increase technical training and guidance for medical and health personnel, and improve the standardization of personnel operation. Data such as nucleic acid and serum detection should be collected and reported in time.

　　21. Strict management of asymptomatic infected people. Implement the report, mediation and management of asymptomatic infected persons, analyze the source of infection, and strengthen the tracking, screening and medical observation of close contacts. On the basis of nucleic acid detection, antibody, CT and hemogram examination should be carried out for asymptomatic infected people. Asymptomatic infected persons who have clinical manifestations during centralized medical observation should be immediately transported to designated medical and health institutions for standardized treatment, and the relevant information in the epidemic reporting system should be revised in time after diagnosis, and no delay, omission or concealment is allowed. Close contacts of asymptomatic infected persons should be tested for nucleic acid. After the asymptomatic infected people are released from centralized medical observation, they will be included in the management of basic public health services, and follow-up, follow-up and health management will be done well. For asymptomatic infected persons and their close contacts, case information should be formed in time and pushed to the government sharing exchange platform or data center at the same level to realize closed-loop management of data and incorporate it into health code management in time.

　　Third, organizational guarantee

　　(A) compaction Sifang prevention and control responsibility

All localities should establish an inspection mechanism, focus on the key areas and links of epidemic prevention and control, carry out supervision and inspection on the implementation of normalized prevention and control measures and responsibilities, strictly enforce discipline requirements, and compact the responsibilities of the four parties. Those who engage in formalism, bureaucracy, seeking no practical results, deceiving their superiors and deceiving their subordinates, etc., which seriously affect the prevention and control work, must be resolutely investigated and dealt with and seriously held accountable.

　　(2) Adhere to scientific prevention and control according to law.

　　27. Prevention and control according to laws and regulations. All localities should strictly implement the laws and regulations on epidemic prevention and control and emergency response to public health emergencies, perform their duties of epidemic prevention and control according to law, improve decision-making procedures, standardize decision-making processes, and timely disclose relevant information on epidemic prevention and control. Disciplinary committees at all levels should strengthen supervision and strictly enforce discipline. Health administrative departments at all levels should strengthen law enforcement inspection on the prevention and control of infectious diseases, and severely investigate and deal with illegal acts such as concealing and delaying the reporting of epidemic situations. All relevant departments should strengthen supervision over the prevention and control of infectious diseases and resolutely investigate and deal with illegal acts.

　　28. Scientific and precise prevention and control. All localities should promptly judge the epidemic situation and prevention and control capabilities, and scientifically and dynamically adjust the risk level and emergency response level according to the situation. The Provincial Center for Disease Control and Prevention carries out the risk level assessment with counties (cities, districts) as the unit, and the provincial health and wellness committee timely announces the adjustment; According to the published risk level, each city and state scientifically demarcates the prevention and control area to the smallest unit, and accurately implements various control measures.

　　(3) Strengthen work security measures

Eating zongzi on Dragon Boat Festival is a folk custom and elegant taste inherited for thousands of years. However, glutinous rice is sticky and high in calories, which can easily cause gastrointestinal discomfort if eaten improperly. The following are the scientific methods for you to disassemble healthy eating zongzi from the dimensions of selecting zongzi, food intake, collocation and time, so that traditional delicacy and health can have both.

First, choose zongzi according to your physique:Choosing food according to the symptoms is better for health. Glutinous rice features: it is warm and sweet, and people with spleen and stomach deficiency and cold can eat it to warm the middle and replenish qi. However, damp heat constitution and those with weak digestive function need to be cautious, and it is easy to produce phlegm and dampness or block the stomach. Advanced selection of stuffing: healthy and preferred miscellaneous grains Zongzi (oat+red bean+mung bean): the dietary fiber content is increased by 3 times, which delays the rise of blood sugar and is suitable for people who control sugar. Low-sugar red jujube dumplings/red bean paste dumplings: red dates are rich in cyclic adenosine monophosphate, and with low-fat red bean paste, they can replenish qi and blood while reducing sugar load (diabetics are advised to choose the version without added sugar). Low-salt lean meat dumplings: lean pork provides high-quality protein and avoids the high-fat and high-salt trap of pork belly and salted egg yolk. Careful consumption of alkaline rice dumplings: sodium carbonate will stimulate gastric acid secretion, and patients with gastric ulcer are prone to heartburn after eating. Salted egg yolk zongzi: the sodium content of a single salted egg yolk is about 500mg, which is more than 1/4 of the recommended daily sodium intake. People with hypertension need to taste it. Crystal Zongzi: The proportion of glutinous rice flour and white sugar is over 70%, and the GI is as high as 82, which is easy to cause a sudden rise and fall of blood sugar.

Second, the control law:Scientifically and quantitatively determine the standard consumption: adults should eat 1-2 zongzi of medium size (about 150-200g) at a time, and children should halve them to 1/2. It is recommended to eat them in a warm state (the viscosity of cold glutinous rice is increased by 30%, which is more difficult to digest). Special crowd adaptation plan It is recommended for people with diabetes to choose miscellaneous grains zongzi (without sucrose) with low GI vegetables such as celery and bitter gourd. After eating, the amount of staple food will be reduced by 1/3. Old people/children will cook soft and rotten glutinous rice zongzi, cut it into small pieces and chew it for more than 20 times, so as to avoid choking risk. Patients with gastrointestinal diseases will use 1/4 zongzi+1 bowl of millet porridge instead of dinner, and use porridge to protect gastric mucosa.

Third, gold collocation:Dietary fiber combination boxing with balanced nutrition and greasy solution: high-fiber vegetables such as cold-mixed dandelion and stir-fried broccoli (fiber content ≥3g per 100g), or one kiwi fruit (rich in actinidine to promote protease activity) half an hour after a meal. Classic menu: 1 miscellaneous grain dumpling+1 garlic oil wheat dish+1 bowl of red bean and barley porridge, and the dietary fiber intake can reach 1/2 of the daily recommended amount. Fermented teas are preferred for relieving boredom: cooked Pu ‘er and aged oolong tea contain tea polyphenols ≥15%, which can decompose fat particles in zongzi (patients with gastric ulcer are advised to drink warm tea and avoid drinking tea on an empty stomach). Medicinal porridge: Chinese yam lotus seed porridge (Chinese yam strengthens the spleen and lotus seeds nourish the heart), which can not only neutralize the stagnation of glutinous rice, but also protect the spleen and stomach. Warning of diet minefield: avoid high-sugar and high-fat foods such as milk tea and fried spring rolls. This combination will extend the digestive time of the stomach to more than 6 hours.

Fourth, time management:Scientific eating does not hurt the stomach. The best time to eat is breakfast (7:00-9:00) or lunch (11:30-13:30), when the pepsin activity reaches its peak, with 1 egg and 1 cup of soybean milk, protein can wrap glutinous rice to reduce gastric mucosal irritation. During the taboo period, the fasting state is reminded: the pH value of gastric acid is < 2, and glutinous rice is easy to condense into blocks when it meets strong acid, which will induce bloating and stomachache (it is recommended to eat a piece of whole wheat bread to pad the stomach first). 3 hours before going to bed: the emptying speed of zongzi is 2 times slower than that of rice, which is easy to cause food reflux when lying down. It is recommended to walk for 20 minutes after dinner to promote digestion.

　

Five, storage mystery:Fresh-keeping and heating should pay attention to the principle of ready-made and ready-to-eat: handmade dumplings are recommended to be eaten on the same day, and the shelf life of vacuum-packed dumplings on the market needs to be checked (stored at room temperature for no more than 90 days, and eaten within 2 hours after opening). Short-term storage (1-3 days): sealed, refrigerated at 4℃, boiled and steamed for 12 minutes before eating (to kill listeria). Long-term storage (within one month): sub-package and freeze at-18℃ for a single serving, and thaw completely after reheating to avoid indigestion caused by external heating and internal cooling.

Six, the crowd taboo:Special physique needs to avoid the physical type. Alternatives to the forbidden area: seafood dumplings for patients with high uric acid/gout, vegetarian dumplings with preserved meat (purine content > 150 mg/100 g) and winter melon seaweed soup (promoting uric acid excretion). For those with allergic physique, check the ingredient list in advance, and choose the wisdom of eating dumplings with pure glutinous rice and alkaline water during the Dragon Boat Festival, which is hidden in the philosophy of "restraint" and "balance" Following the cross rule of "choosing coarse grains, controlling the amount, matching vegetables and choosing the time", we can not only taste the dense and mellow glutinous rice, but also protect the lightness and comfort of the stomach. If you have abdominal distension due to careless eating, you can drink tea substitute cooked with 15g of fried malt and 9g of hawthorn to help you get rid of stagnation and enjoy the Dragon Boat Festival.

The spread of COVID-19 epidemic around the world has brought great impact on the world economy, especially on international trade. In Guangdong, a major foreign trade province in China, the total import and export volume decreased by 11.8% in the first quarter of this year, of which exports decreased by 14.4%. A large number of foreign trade enterprises are facing the dual pressures of insufficient supply of raw materials and reduced orders.

In the interview, the reporter found that with the continuous acceleration of export tax rebate and the implementation of a package of preferential policies to support epidemic prevention and control, the pressure and burden of export enterprises have been reduced, and they have used the saved funds on the "cutting edge" and quickly responded to the new situation of foreign trade by changing production and reselling, and achieved a breakthrough against the trend.

Tax "blood transfusion" to help enterprises tide over the difficulties

In contrast to the obvious decline in foreign trade data, it is the steady increase in tax policy support.

According to statistics, in the first quarter of this year, the tax authorities of Guangdong Province handled 65.674 billion yuan of tax refund for 35,000 export enterprises in the province, and the proportion of "non-contact" processing was nearly 100%. Since February, the average processing time of export tax rebate in the province has been shortened to five working days, which is half of the national average processing time last year.

Guangdong Yuanhua New Materials Co., Ltd. is a production-oriented export enterprise specializing in household products such as anti-skid mats and yoga mats. Due to the foreign epidemic, the company’s export orders have been greatly reduced, and its sales in March decreased by nearly 50% compared with the same period last year. After learning about this situation, the tax department of Foshan City immediately provided online guidance to enterprises to submit export tax refund applications, and at the same time strengthened communication and coordination with the state treasury, and soon returned the tax to the enterprise account. Wang Lianzhen, the company’s financial controller, said: "The export tax rebate of nearly 3 million yuan has reduced our financial pressure and enhanced our confidence in the follow-up development."

While production-oriented enterprises enjoy the rapid "blood transfusion" of export tax rebate, many enterprises engaged in cross-border e-commerce and foreign trade transactions have also received tax relief packages to varying degrees.

Huizhou Chuanghui Plastic Co., Ltd. is a small and micro enterprise, mainly producing plastic toys, all of which are exported to Europe, America, Canada and other places. Affected by the epidemic, the turnover of enterprises fell by 60%, while the cost of manpower and logistics increased a lot, which made business operators "under great pressure". Yu Zhiqiang, the person in charge of the company, said: "The export tax rebate exceeding 30,000 yuan and the social security fee reduction of 75,000 yuan have solved our urgent needs and added a bit of confidence for enterprises to tide over the difficulties."

In order to help foreign trade enterprises meet the challenges, State Taxation Administration of The People’s Republic of China Guangdong Provincial Taxation Bureau has specially set up ledgers for key industries and major export enterprises, deeply understood the impact of the epidemic on enterprises and their demands, and adopted a series of targeted measures to ensure the stable operation of the foreign trade industrial chain supply chain.

Moving to China, the new platform has new opportunities.

At present, many foreign trade enterprises are actively catering to the new market situation and new trends.

Exporting to domestic market is a self-help method chosen by many foreign trade enterprises. The trend of new industries, such as 5G and industrial Internet, has enabled Jinbao Electronics (China) Co., Ltd. to "sniff" business opportunities.

"After discussion, we decided to access the regional 5G supply chain and provide base station equipment, wireless modules and other products for well-known domestic communication enterprises, from foreign trade to domestic sales." Liu Yuanhua, the company’s financial manager, said, "Thanks to the help of the tax department on the road to transformation, we dare to take a bold step." He said that the tax reduction red envelopes that have been received in succession have revitalized the company’s capital flow and enabled the company to invest more capital in optimizing production equipment and production processes for domestic customers.

At the same time, the market transformation drives a series of adjustments in the development and operation of enterprises. How to apply for the certificate of enterprises turning to domestic sales? How to connect the departments of taxation, customs and foreign exchange management? After learning about Jinbao Electronics’ demands, the tax department of Dongguan City quickly formed a special group to provide one-on-one counseling to help enterprises establish a new tax-related management model and follow the trend of "transformation".

For the enterprise itself, "export to domestic sales" is the beginning of accelerating the layout of the domestic market, and Guangdong Yuanhua New Materials Co., Ltd. has a similar plan. During the epidemic, the popularity of home fitness products continued to rise. Concerned about this trend, Yuanhua New Materials quickly adjusted its marketing strategy and turned to domestic sales.

In order to attract more potential customers and increase customer stickiness, the company aims at the needs of domestic consumers while accelerating cooperation with online e-commerce, and promptly adjusts the product delivery structure. "The fast tax refund has increased the capital’ living water’, and we immediately invested in product research and development to accelerate the development of new fitness products with both fashion sense and scientific and technological content." Wang Lianzhen said: "The tax department also counseled us to publish product information on the Zhilian platform of Guangdong tax industry chain to help us further expand our sales."

At present, adjusting the direction of production and sales in line with market demand has made Yuanhua new materials catch the "express train" of domestic sales, and the company’s sales in March have doubled compared with that in February.

Demand-oriented, cross-border transformation and new development

In order to better adapt to the new foreign trade environment, many enterprises also seize business opportunities from crises and difficulties by adjusting their development strategies in time, expanding markets and grasping orders. When the epidemic broke out, Gree Electric made emergency cross-border production of epidemic prevention materials such as masks to help the global fight against the epidemic.

After learning the news of cross-border production of epidemic prevention materials in Gree Electric, the Guangdong provincial tax authorities immediately used big data to help them get through all production links. The tax department of Zhuhai has specially established the "Gree Department" service WeChat group to provide real-time tax analysis suggestions to enterprises.

There are many examples of enterprise innovation and change under the new situation. As the representative of cross-border e-commerce in Hengqin, Cross-border Network Technology Co., Ltd. enjoys the unique advantages of Macao-China-Portugal platform. During the epidemic period, the company launched the "anti-epidemic plan-global collection of medical materials" to ensure the supply and sales of epidemic prevention materials.

In this process, the tax department of Hengqin New District of Zhuhai actively uses tax big data to bridge the gap between cross-border companies and hundreds of enterprises such as Hengqin Enterprise Park, and timely implement tax incentives for cross-border companies. "The efficient and meticulous service of the tax department allows us to fully enjoy policy support." Zhou Yunxian, head of Cross-border Network Technology Co., Ltd. said.

Policy support continues to increase. The the State Council Standing Committee held on April 7th decided to play a set of "combination boxing" to stabilize the basic foreign trade and foreign investment. Among them, the Canton Fair, as the weather vane of the national foreign trade industry, will be held online for the first time in June this year. According to the work arrangement, the Guangdong Provincial Taxation Bureau will "move" the tax publicity and counseling online at that time, and it is expected to provide publicity and counseling services for 25,000 exhibitors.

With the support of tax policies and tax authorities, a large number of Guangdong enterprises have launched a double upgrade of operation and management, which has accelerated the pace of Guangdong’s foreign trade stabilization and recovery. From the economic data in March, this positive trend has been reflected: in March, the added value of industrial enterprises above designated size, investment in fixed assets and the decline of import and export in Guangdong Province narrowed by 18.5, 12.7 and 9.3 percentage points respectively compared with January and February.

　　If you can’t grow hair, you will get sick.

　　Recently, 28-year-old programmer Xiao Wang

　　Due to discomfort after taking germinal pill.

　　Going to the hospital was actually diagnosed as

　　Severe drug-induced liver injury

　　Guiding experts:

　　Luo Ying, attending professor, deputy chief physician, master of medicine, attending physician of cosmetic dermatology, Dermatology Hospital of Southern Medical University.

　　With the acceleration of social rhythm, the increase of pressure and the change of living environment, hair loss has become a worry for most young people.

　　Xiao Wang, a 28-year-old programmer from Dachang, failed in all kinds of hair growth methods. By chance, when he browsed social networking sites, he found that a certain brand germinal pill received a lot of praise and immediately placed an order.

　　After taking the medicine for 3 weeks, Xiao Wang’s hair loss has not changed, but he also has symptoms such as yellow skin, yellow urine, itching all over the body, poor appetite, shortness of breath and fatigue.

　　Xiao Wang rushed to the doctor and was diagnosed with severe drug-induced liver injury. Doctors said that the main component of germinal pill was Polygonum multiflorum Thunb, which was hepatotoxic.

　　Why can’t germinal pill grow hair?

　　At present, the main ingredient of germinal pill sold in the market is Polygonum multiflorum Thunb, supplemented by black sesame seeds, black beans and other ingredients as pills. Polygonum multiflorum Thunb. belongs to the category of blood tonic medicine of traditional Chinese medicine, and its main functions are nourishing essence and blood, moistening intestines, detoxicating and stopping malaria.

　　According to the regulations, the daily dosage of raw Polygonum multiflorum in health food should not exceed 1.5 grams, and the daily dosage of prepared Polygonum multiflorum should not exceed 3.0 grams.

　　Polygonum multiflorum Thunb contains anthraquinones such as emodin, chrysophanol and emodin methyl ether, which can also cause certain damage to liver cells. Therefore, patients with liver dysfunction should use drugs carefully and reasonably under the guidance of doctors to avoid aggravating liver damage (hereinafter referred to as liver damage).

　　Medical liver damage is a common adverse drug reaction. About 20% of the cases of liver damage caused by Polygonum multiflorum Thunb and related preparations have a dosage exceeding that specified in the instructions or pharmacopoeia, which may greatly increase the risk of liver damage of Polygonum multiflorum Thunb.

　　In addition, the liver injury caused by Polygonum multiflorum Thunb is also related to the organism factors, which has the characteristics of sporadic, hidden, individual differences and unpredictable, so it is difficult for ordinary consumers to scientifically and accurately assess and avoid the safety risk of Polygonum multiflorum Thunb.

　　In addition, the ingredients of most germinal pill in the market are not clear enough, and taking too much black sesame seeds and black beans for a long time may even lead to the risk of gaining weight. Therefore, the general public should use drugs with caution, and if they must be used, they should be carried out under the guidance of professional doctors.

　　Drugs are like a double-edged sword. Rational use can cure diseases, while improper use will endanger health. It is a three-point poison, and many drugs on the market are hepatotoxic.

　　The liver is the most important organ for metabolism and detoxification in human body. If drugs enter the human body, it is the liver that is the first to be damaged.

　　In a hit variety show, the famous hostess ate at least nine different types of health care products in just half a minute, including whitening oral liquid, donkey-hide gelatin and grape seed … Little did she know that taking too many health care products could also lead to liver damage.

　　As a dietary supplement, health care products can achieve good results when the body can’t meet the needs. If the body is not lacking, blindly supplementing will increase the burden of liver metabolism and liver damage will follow.

　　Drug-induced liver injury can not be ignored.

　　A team of scientists from China published a paper online in the international academic journal Gastroenterology, saying that a study of 25,927 patients with drug-induced liver injury in 308 hospitals in Chinese mainland found that the incidence of drug-induced liver injury in China has now surpassed that in western countries, and it is estimated that the annual incidence rate is at least 238.0/100,000. Researchers believe that drug-induced liver injury has become one of the problems that cannot be ignored in China.

　　Further analysis of patient data, the researchers found that Chinese herbal medicine and health care products accounted for the highest proportion of drugs causing liver injury, reaching 26.81%.

　　In western countries, anti-infective drugs are the main cause of drug-induced liver injury. According to the author, the use of Chinese herbal medicines, health products and dietary supplements is increasing all over the world, especially in China.

　　A large part of Chinese prefers to use traditional Chinese medicine, because they mistakenly believe that these drugs have little or no side effects.

　　Drug-induced liver injury is one of the most common adverse drug reactions in clinic, which can lead to liver failure and even death in severe cases. In this study, the researchers found that there were 280 cases of liver failure, 2 cases of liver transplantation and 102 cases of death.

　　Especially for patients with liver diseases, they have already suffered from liver injury. If you choose the wrong drugs for treatment, it will definitely increase the burden on the liver, resulting in liver treatment and liver injury.

　　How to grow hair correctly

　　So, how do we grow hair correctly?

　　First of all, you can try dietotherapy to achieve a balanced diet. Usually, you can eat more foods rich in high-quality protein, vitamins and trace elements, such as fish, eggs, milk, bean products, vegetables and fruits.

　　Secondly, it is necessary to regulate nerves and reduce the influence of mental factors. Excessive stress and frequent staying up late have a great influence on hair growth, so patients with hair loss must ensure a good attitude and adequate sleep to avoid emotional tension, anxiety and irritability, which is conducive to the healthy growth of hair.

　　Finally, local massage can be used. Local massage can promote blood circulation of scalp, improve blood supply to hair follicles, and be beneficial to hair growth. You can massage your scalp by hand or gently comb your hair with a horn comb every day to promote blood circulation in your head.

　　In addition, choose the right hair care products. Don’t wash your hair too often, 2-3 times a week. If there is more oil, the frequency of washing your hair can be increased to once a day.

　　It is recommended to treat hair gently when washing and protecting, and it is not advisable to rub hair and scalp vigorously when washing hair. Choose a suitable water temperature, not too cold or too hot. The water flow can make the head skin feel warm. If it is too hot, it will cause harm to the scalp and hair. Hair conditioner can be used if it is long hair or curly hair after dyeing, but it should not touch the scalp.

　　Women should not sew separately in the same position for a long time, or comb too tight ponytails, curls or braids for a long time, so as not to cause traction baldness. Hair dyeing, perm and other styling should not be too frequent, and it is best to have an interval of more than 3 months.

　　If you need medication, or want to know more about medication, you can consult a doctor or pharmacist and use drugs rationally under their guidance.

　　On the morning of November 4th, the 24th meeting of the 12th the National People’s Congress Standing Committee (NPCSC) held a joint meeting to ask about the implementation of the environmental protection law. Wang Mingwen, a member of the National People’s Congress Standing Committee (NPCSC), said that since 2011, incidents such as "arsenic poisoning", "blood lead" and "cadmium rice" have occurred frequently, making heavy metal pollution one of the most concerned public events. Soil pollution and the food security and national health problems caused by it have caused public concern and even panic.

　　"What is the overall situation of soil pollution in China at present? What are the difficulties and problems in the management and use control of polluted agricultural land, especially cultivated land polluted by heavy metals and industrial polluted plots? What measures have been taken? What are your plans for the next step? " Wang Mingwen asked questions.

　　Chen Jining, Minister of Environmental Protection who participated in the inquiry, introduced that from 2005 to 2013, the State Council made a preliminary survey of soil pollution in China. The survey results show that the over-standard rate of soil pollution sites in China is 16.1%, of which the proportions of slight, mild, moderate and severe pollution sites are 11.2%, 2.3%, 1.5% and 1.1% respectively. The over-standard rate of farmland soil points is 19.4%, which is a little higher. The proportions of slightly, slightly, moderately and severely polluted points are 13.7%, 2.8%, 1.8% and 1.1% respectively.

　　"The over-standard rate of points is not the actual over-standard rate of areas." Chen Jining explained that the over-standard rate of points refers to where there will be soil pollution problems, what kind of problems and what causes, and does not mean that 19.4% of the soil is completely polluted.

　　Chen Jining said that the current difficulties and challenges in soil pollution prevention and control mainly include: First, the base number is unclear, and China has not yet established a list of agricultural land and a list of contaminated land classified according to pollution degree. The second is the lack of laws and regulations. At present, there is no special law for the prevention and control of soil pollution in China, and the departmental regulations for environmental supervision of polluted plots and agricultural land have not been promulgated, so there is no basis for supervision. Third, the corresponding technical standards and specifications are not sound enough. There is a lack of operational standards and norms in the investigation, risk assessment, treatment and remediation of soil pollution, and the technical system needs to be improved urgently. Fourth, the regulatory capacity needs to be strengthened. Local environmental protection departments are not strong enough in soil pollution supervision, especially the lack of professionals, which urgently needs to be improved.

　　Chen Jining said that on May 28th this year, the State Council issued the Action Plan for the Prevention and Control of Soil Pollution (namely "Ten Soil Articles"), and the next step will be to promote the implementation of the "Ten Soil Articles" and do a good job in five aspects.

　　First, accelerate the promotion of legislation. Cooperate with the Environmental Protection Committee of the National People’s Congress to do a good job in drafting, revising and demonstrating the law on the prevention and control of soil pollution, and at the same time formulate departmental regulations such as the introduction of soil management measures for polluted plots and agricultural land.

　　The second is to carry out a detailed survey of soil pollution in the country. In conjunction with the land, agriculture and other departments, on the basis of existing relevant investigations, we will carry out a detailed investigation of soil pollution with agricultural land and enterprise land in key industries as the focus. Complete the investigation of agricultural land pollution by the end of 2018, and master the distribution of contaminated land and its environmental risks in key industries by the end of 2020.

　　The third is to establish and improve relevant standards and norms. Revise the quality standard of soil environment for construction land, and revise the technical specifications of soil environment monitoring, investigation and evaluation, risk control, treatment and restoration for construction land, as well as the technical guidelines for environmental impact assessment.

　　The fourth is to strengthen the environmental management of construction projects. In the examination and approval of environmental impact assessment involving hazardous chemicals, heavy metals and other construction projects with significant environmental risks, it is clearly required to increase the content of soil environmental impact assessment, strengthen environmental access, and prevent construction projects from polluting soil and groundwater. Study and carry out environmental risk assessment of closed and relocated enterprises, and further strengthen environmental impact assessment management of soil environmental quality.

　　The fifth is to urge local governments to improve the soil environmental management system. Guide local governments to establish a system of soil environmental investigation and risk assessment for construction land, gradually establish a list of contaminated plots and a negative list of their development and utilization, establish an information communication and sharing mechanism between urban and rural planning, land resources and environmental protection departments, and establish a linkage supervision mechanism.

　　Jiang Daming, Minister of Land and Resources, said that the Ministry of Land and Resources will strengthen the control of the use of contaminated land, accelerate the establishment of a departmental linkage mechanism for the identification, remediation, planned use control and land access management of contaminated sites, gradually establish a list of contaminated plots, and determine the negative list of development and utilization to prevent improper use of contaminated sites without remediation; At the same time, it is necessary to do a good job in source control and resolutely curb the generation of new soil pollution. The Ministry of Land and Resources will cooperate with the National Development and Reform Commission and the Ministry of Environmental Protection to strictly control the access of the "three high" projects and strictly control the pre-examination of construction land and land approval.

　　Chen Zhenggao, Minister of Housing and Urban-Rural Development, said that the tasks undertaken by the Ministry of Housing and Urban-Rural Development are mainly "two strict controls" in the implementation of the State Council’s "Ten Articles of Soil": strictly control the industrial sites that have been polluted, and the use of these sites must be guaranteed; Strictly control the spatial layout to prevent new land pollution.

　　Zhang Taolin, Vice Minister of Agriculture, said that the quality of agricultural products is not a simple correspondence with the environmental quality of cultivated land. Generally speaking, the main agricultural products in China are safe and secure. At present, the soil pollutants in cultivated land in China are slightly over-standard, and the proportion of severe pollution is relatively small. Some measures can be taken to control and make safe use of them. Generally speaking, most of the polluted cultivated land in China is preventable, controllable and treatable, and the serious pollution is irreversible.

　　Beijing, November 4 th
