Meridian can therefore decide life and death, cope with all diseases, and regulate excess and deficiency, which are indispensable. It means: whether the meridians are unobstructed can determine a person's life and death. In the process of coping with various diseases and regulating the deficiency and excess of the human body, we must dredge the meridians.

This sentence in Huangdi Neijing describes the importance of unobstructed meridians to the human body by "deciding life and death". The general principle of meridians is health, and if meridians are blocked, all diseases will occur.

Extended data:

Huangdi Neijing is divided into Lingshu and Suwen, which is the earliest medical classic in China and one of the four classic works of traditional medicine (the other three are Difficult Classic, Treatise on Febrile Diseases and Shennong Herbal Classic).

Huangdi Neijing is a comprehensive medical work, which establishes the theories of Yin and Yang, five elements, pulse condition, Tibetan image, meridians, etiology, pathogenesis, symptoms, diagnosis, treatment, health preservation and luck.

Discussing medicine with a holistic view presents a "holistic medical model" of nature, biology, psychology and society. Its basic material comes from the long-term observation of life phenomena in ancient China, a lot of clinical practice and simple anatomical knowledge.
