Health care means protecting health. It also refers to the protection and promotion of human health and the prevention and treatment of diseases. Health care has a long history in China. As early as the Spring and Autumn Period and the Warring States Period, Huangdi Neijing, a classic work of traditional Chinese medicine, comprehensively summarized the experience of health care in the pre-Qin period, and clearly pointed out that "the sage failed to cure the disease, the husband's disease was medicine, and the disorder was the post-treatment. It's not too late to cross the well and fight again! " The concept of health preservation laid a foundation for the development of traditional preventive medicine and health preservation in China. For thousands of years, traditional Chinese medicine practitioners and health care experts have accumulated and summarized the health care experience spread among the people, and written a large number of health care monographs, which promoted the development of traditional health care in China. There are many schools of traditional health preservation in China, which can be roughly divided into six schools: spirit, dynamic form, solid essence, regulating qi, food tonic and medicinal bait. Each school's health-preserving theory is self-contained, with its own strengths and eclecticism, forming a unique health-preserving method in China.
