The 21st century is the century of mankind's pursuit of health. The 21st century is a new era of health for all; From developing the economy to caring for one's health in the 21st century; What people need most in the 21st century is health. Health is the most valuable wealth of life! Nothing is possible without a healthy body and mind.

However, the current sub-health conditions of Chinese residents urgently need to be corrected, and their health awareness and health behaviors need to be strengthened. It is necessary to further publicize scientific fitness knowledge, oppose cults and advocate civilization. The main behaviors of health food enterprises need to be further standardized. At the same time, our social health service institutions and talents are extremely short, facing the competition of "entering the WTO", the national health industry and national health culture need to support and promote. It can be seen that the state of health undertakings in our country is not optimistic, and it is inevitable to construct "great health project" :

The new medical reform advocates giving priority to prevention, and the State Administration of Traditional Chinese Medicine has clearly put forward the guiding principle of "treating and preventing diseases". Then promoted the rapid maturation of our great health industry. Life and health is a whole process of care, in the face of modern diseases, later confrontational treatment is often too late.

With the rapid improvement of economic development and people's living standards, while people are enjoying the fruits of modern civilization, civilization disease, that is, lifestyle disease, is becoming increasingly popular, and more and more people are in sub-health state. Living conditions have improved, but food safety and sanitation problems have emerged, and the quality of life has declined. Nowadays, people have serious chronic diseases and pay no attention to sub-health conditions, which has seriously affected people's health and consumed a large amount of social medical resources and medical expenses. Many people are also poor due to diseases.

The famous British biologist Ba Feng recently published research results that the life span of mammals is generally 5 ~ 7 times that of living long-term, such as cattle growth period of about 6 years, life span of about 30 ~ 42 years. Human growth period is about 20 ~ 25 years, the natural life span should be 100 ~ 175 years. But such longevity has not been achieved by humans. The reason is caused by human beings themselves, such as not paying attention to scientific health care, scientific diet, optimize the environment and so on. To set up the concept of great health and take the initiative to pay attention to life from various aspects is necessary to ensure good health and prolong life. The average life expectancy in China has risen from less than 50 years to 73 years, but many are bedridden or semi-bedridden, surviving but with a low quality of life.

In different historical stages, people have different health cognition and disease prevention priorities, and the health content is constantly updated. For example, in the United States, 1875 ~ 1925 was the environmental era, characterized by smallpox immunization, surgical disinfection, public health services; 1925 ~ 1950 is the era of medicine, characterized by the widespread use of sulfonamide, penicillin, antituberculosis drugs; 1950 ~ 1980 is the life style era, characterized by cardiac surgery, heart transplantation, coronary artery bypass; Thirty years later, in 2009, President Obama stated and called for reform of the American health care system: "It is the excessive costs of health care that pose a great threat to our economy. It is an ever-higher hurdle for our families and businesses. It is an intractable time bomb for the federal government. It is one that American life cannot afford." The rapid economic development of the United States after World War II brought with it diseases of wealth such as cardiovascular and cerebrovascular diseases and diabetes, which still haunt us today. The shift in focus to prevention in developed countries is a response to the challenges posed by changing lifestyles. China, which has been transitioning from food and clothing to a well-off society in an all-round way, also faces the same health challenges. The increasing number of sub-healthy people, the rising incidence of chronic diseases, and major public health events have frequently sounded the alarm, prompting the government to put forward the "preventive migration strategy".

"Great unity of the world and great harmony of mankind. General health is a shared responsibility of all mankind. It involves equitable access to basic rights and interests, physical and mental health, collective prevention of transnational threats, and more importantly, peaceful coexistence, cooperation and common progress of mankind. To build a "World Health Organization alliance" and create a force of civilization and culture, it will surely play an important role in the sustainable, innovative development and friendly collaboration of regional and global health undertakings.
