There are 200 medical books in two volumes, one of which is similar to Huangdi Neijing, and the other is about the art of keeping in good health. Among them, there are Health-preserving Prescription, Yin-Yang Harmony Prescription, Ten Questions, On the Road to the World and so on. , involving sexual health care, eugenics and health care. For example, in the eighth question of Ten Questions, I asked Mr. Wei Xiao for the way to cure arrogance. Because I worked hard to cure the world, I lost my sexual function, so my family was in chaos. After learning the way to control arrogance, sexual function will recover, thus "settling down in Yao and staying at home in Ning", which shows that learning the way to live in the house can harmonize the relationship between husband and wife and improve health. The theory of "Seven Losses and Eight Benefits" in Tan Zhidao in the World is a great contribution to the theory of atrioventricular health care in China, and it still has important reference value for indoor health care.
