Composition: "Spring grows in summer, autumn harvests in winter" is the law of the growth of all things, and it is also the way of health preservation advocated by Chinese medicine. Please take this as the topic and do it yourself. Chinese medicine pays attention to the four seasons of Yin and Yang, spring and summer, autumn harvest and winter storage, which is a natural law. People should conform to the laws of nature, for example, there should be a kind of hair growth in spring, slow down and get up early in the evening. Winter can't be too ostentatious and divergent, everything is going on in the dark. The concept of TCM health preservation varies from time to time, from place to place and from person to person.

TCM health preservation includes a series of health preservation principles, such as nourishing body and mind, coordinating yin and yang, conforming to nature, nourishing diet, carefully living, regulating viscera, dredging meridians, abstinence and nourishing essence, invigorating qi and regulating breath, and proper exercise and rest. Coordination and balance is its core idea. When a person's body reaches a balance point, it is the healthiest and "disease prevention".

In terms of health care, the most important thing is to nourish the heart. "Being indifferent to my heart all my life" is a high spiritual realm. Everyone has joy, anger, worry, thinking, sadness, fear and surprise. This is a person's seven emotions, too much is too emotional. "People who often look at the world, those who are kind live long, those who are good in quality live long, those who are large in quantity live long, and those who are brief live long. Gai Si, the end of benevolence is also, so the benevolent is born. " Benevolence is to be gentle, kind, generous and humorous. Benevolence and virtue are the intrinsic elements of a person's health. Huangdi Neijing emphasizes "indifferent to nothingness" and says "indifferent to nothingness, conforming to the true qi, hiding the spirit inside, and preventing diseases". In short, it is to be "light".
