Without national health, there will be no overall well-off society. Health is the most important indicator of a happy life. Health is 1, others are the latter 0. Without 1, any number of zeros is meaningless. National fitness is the foundation and guarantee for the whole people to enhance their physical fitness and healthy life, and the foundation of building a sports power lies in mass sports. To promote national fitness, we should closely focus on meeting people's needs, make overall plans to build national fitness venues and facilities, and build a higher-level national fitness public service system to better meet people's fitness and health needs.
