Abstract: Since the 18th National Congress of the Communist Party of China, General Secretary Xi Jinping has attached great importance to the issue of people's health. On the basis of inheriting the thoughts of Marxist classic writers on people's health, developing the views on people's health made by previous leaders of China, and summarizing the great practice of protecting people's health since the 18th National Congress, General Secretary Xi Jinping creatively has put forward a series of new views, conclusions and measures, which formed an important thought on people's health. Its main contents include: taking the leadership of the party as an essential guarantee, the people's health as the value objective, the grassroots units as the focus, reform and innovation as the driving force, the rule of law as the fundamental bottom line, and establishing a new health concept of "extensive hygiene, comprehensive health". A deep understanding of the ideological connotation of General Secretary Xi Jinping's important thought on people's health has far-reaching implications for successfully defending against the COVID-19 Epidemic, promoting the construction of a "healthy China", improving the modernization of the national governance system and governance capability, and is of great practical value for the realization of building a well-off society in an all-round way, and it is also helpful to provide the Chinese wisdom and plan for promoting the work for the world health.
