He mentioned in his medical book "A Thousand Daughters to Prescription": To nourish qi, we must first reconcile the three qi of heaven, earth and man, and then we can maintain health and live a long life. Summed up the predecessors' health care experience, which is the concept of heaven, earth and people.

He believes that heaven and earth are one of the three kinds of qi in the human body, and they need to cooperate and harmonize with the other two kinds of qi in the human body, popularity and local qi, in order to achieve the effect of keeping healthy and strengthening the body.

The qi in the human body is nursed back to health, harmonized and unblocked through the gradual circulation of qi in heaven and earth, and the life activities of the body are maintained through constant breathing, eating and other behaviors. This theory profoundly influenced the later practice of TCM health preservation and qigong.

Since the Tang and Song Dynasties, the synchronization of heaven, earth, man and three qi has gradually become one of the core theories of TCM health preservation, which is reflected in the classic literature of TCM such as Lingshu Jing and Suwen, and has become a kind of health preservation wisdom deeply rooted in people's hearts. Modern qigong, Tai Chi and other fitness methods have also integrated this theory, organically integrating the human body, nature and the universe, and paying more attention to the coordination and balance within the human body.

Extended data

Although the theory of synchronization of heaven, earth and man originally refers to the harmonious balance of natural qi between man and the universe, with the changes of the times, many people began to extend it to the harmony between inner world and social relations.

In personal growth and practice, the synchronization of heaven and earth means that individuals need to establish a good relationship with themselves, others and the environment, realize the coordination and reconciliation of mind, body and behavior, and then achieve a peaceful, clear and comfortable quiet state, meet inside and outside, and create a better life.

As far as social relevance is concerned, the synchronization of three gases means cooperation with others, social relations and the construction of a green and harmonious society. For example, some people put forward the idea of establishing harmony between man and nature, aiming at encouraging people to realize the balance and coordination between material culture and ecological environment. Some people call it "the way of three qi", emphasizing the subtle and magical connection between man and others, nature and the whole universe, which makes people pursue harmonious, peaceful, friendly and sustainable social relations and effectively promote the harmonious future of mankind.

The synchronization of heaven and earth is not only limited to the harmony between the body and the natural environment, but also belongs to a rich and broad philosophy and cultural thought, which has far-reaching and extensive humanistic value.
