In order to implement the requirements of the 19th National Congress of the CPC on "deepening the patriotic health campaign". Commemorate the 65th anniversary of patriotic health campaign. Comprehensively summarize the great achievements made by our patriotic health campaign. Promote theoretical innovation and scientific development in patriotic health work in a new era. Promote healthy China's construction. Under the guidance of the office of the National Patriotic Health Campaign Committee, the Chinese Preventive Medicine Society and the Chinese Medical Association held the "2017 National Patriotic Health Campaign Academic Forum" in Haikou, Hainan Province from December 4-5. The theme of the conference is "New Era, New Mission, New Development --- Patriotic Health Campaign Helps Healthy China." On the expert roundtable interviews with experts in the forum, Prof. Gong Peng, Dean of Tsinghua University's School of Science, Director of the Department of Earth System Science and Vice President of China's New Urbanization Research Institute, talked about the following points:

Changes in the new era

From the pursuit of quantity to the pursuit of quality of development, the one-sided economy that ignores environmental costs has been transformed into a comprehensive social development based on people. Health is an important part of long-term development in the future and should account for an increasing share of the national economic development as well. In the new era, we, the Chinese, put people and environment in the historical and cultural traditions at the cultural and philosophical level and integrate people's health into the system of nature. Pursuing the overall health, diversity and integrity of the human-earth-day-road system as a unity of purpose and means with the development of modern society has brought about a new leap forward in understanding the concept of general health. China's health? The construction of ecological civilization is praised by all walks of life in the world.

Today, China's economy reaches the middle-income level

In my opinion, China will not fall into the trap of "middle-income earners" as some economists put it. China's cultural traditions and political structures have the advantages of sustainable development. This has given China a unique long-term low-health investment in the world since the founding of the People's Republic and an excellent performance in terms of high returns to health. For example, China's health investment currently accounts for only about 7% of national GDP, while the United States has nearly 20% of its health input. However, China's per capita life expectancy has been catching up with the United States. At the economic level, our country still maintains the world's high level of economic growth. Although it joins the world economy through its opening up, it can drastically reduce the impact of the world economic crisis on China's economic development. Moreover, in recent years, the state has also recognized the problems of unreasonable economic structure and corruption, as well as social injustice. China has also taken a proactive strategy of tackling such problems as structural readjustment, anti-corruption and precise poverty alleviation. This shows the superiority of Chinese culture and political structure.

However, we can do a lot in summing up the theory of China's economic and social development, the theory of great health, and the summing up and promoting the masses' advanced experience in protecting the health from bottom to top. There is also a need to expand the public health research team to increase health professionals in the interdisciplinary fields of environmental protection, economics, planning and management beyond the traditional public health field.

In terms of action, we still have a lot of room for improvement

Now in some hotels around, some people throw a lot of cards in the evening, while others continue to clean up from the ground. There are many more similar things happening in our society. In the past, some of our people clearly saw that environmental pollution endangered the human environment and ecosystem. However, we have the misunderstanding and action of "treating side by side and even pollution first and then management." We still have a lot of unhealthy habits, such as the consumption of preserved foods and the difficulty of smoking cessation in public places. These also need to be strengthened in education, legislation and supervision.

At the level of scientific research, building a healthy China can not be achieved without a full range of innovations

Innovation requires the support of academic research in the social sciences, natural sciences and other fields. Research on big health requires a comprehensive and systematic understanding of everything from microbiological scales, to organi- zations, to individuals, to communities, to natural ecosystems, and to the entire Earth system. Today, with the highly developed Internet of Things, sensor networks, communications networks and information networks, we are more able to monitor the above-mentioned systems at all levels than ever before. We need to make use of the big data that human beings can share to do in-depth analysis, leveraging a new wave of artificial intelligence and breaking the bottleneck of information sharing, strengthening our understanding of the human-environment health system and improving our policy-making level.

In a word: Health is the basis of human existence and is an important part of the planet system that Mother Earth embraces in this human life and work. The health problems must be fully emphasized at all levels, from personal life, working environment and social system governance, to systematically improve the level of health management. Tsinghua's research on environment and health strives to work with the development of the cause of health in the motherland!
