Traditional Chinese medicine health preservation refers to a medical activity that supports life, strengthens physique and prevents diseases through various methods, so as to prolong life. Traditional Chinese medicine pays attention to integrity and systematicness, aiming at preventing and treating diseases before they happen. The famous representative work of TCM theory is Huangdi Neijing. Traditional Chinese medicine health preservation comes from ancient essence medicine, and the level of contemporary Chinese medicine has declined, while ancient Chinese medicine deserves further development and research. The so-called "life" means life, survival and growth; The so-called maintenance means maintenance, recuperation and nourishing. In a word, keeping in good health is to maintain life. Guided by the theory of traditional Chinese medicine, we should follow the changing law of the biochemical set of Yin-Yang and Five Elements to scientifically recuperate human health and vitality. For example, Neijing said: "Nothing is indifferent, the true qi follows, the spirit is hidden inside, and the disease is always safe." Therefore, health care focuses on nourishing the heart, essence, qi and spirit. That is, by nourishing the heart, adjusting the mind and adjusting the life, we can achieve the purpose of maintaining the body, reducing diseases, improving health and prolonging life. On June 7th, 2008, TCM health preservation was approved by the State Council to be included in the second batch of national intangible cultural heritage list.
