Health issue remains to be the cornerstone for people's well-being and national strength. Against the background of "a healthy China" strategy and an all-round realization of a nation of moderate wealth, and with regard to infectious diseases and poor public health emergency management abilities, Party General Secretary Xi Jinping offered important and systematic theories on people's health and the Covid-19 issues: people's life and physical health are top priorities for all level of governments; all of our work should center around the service for people and people's health; we should get rooted in mind the idea of all-round health care for all people; people's health is the most powerful productive force; people's health involves all aspects of health. Study on the practical values of Xi Jinping's important theories on people's health can help to modernize our national governance system and ability, better cope with the serious epidemics, achieve the goal of "Health China 2030" strategy, maintain national safety and international stability, and better present the international significance of China's new-covid-19 fighting experiences.
