Huangdi Neijing emphasizes that people's moral cultivation is the foundation of good health. Because Chinese medicine believes that human qi and blood nutritionists have internal organs and bones. If a person's moral cultivation is not enough, he is always suffering from loss, his desire is difficult to balance, he is constantly delusional and full of complaints, then his qi and blood will fluctuate and he can't nourish his internal organs and bones normally. In the long run, he will be riddled with holes.

Saliva is the essence of human body. Swallow it as long as it is not mixed with other dirty things. Chinese medicine believes that saliva is the essence of nutrition before blood is formed.

In fact, these are all details and tricks. If moral cultivation is not enough and qi and blood are capricious, the foundation of health will be shaken and not solid at all. How long are the branches and leaves?
