Huangdi Neijing said: "Meridian, therefore, can decide life and death, deal with all diseases, regulate deficiency and excess, and be indispensable."

Through this sentence, we can know how important the meridians are. The human body is like a building, and meridians are all kinds of pipes in the building. If the wires and pipes are blocked, the building will fall into darkness. If the sewer pipe is blocked, sewage will pass through the building.

Only when all kinds of pipes are normal can all work be carried out as usual. The meridian is the same. If it doesn't work there, there will be problems. Get rid of it and you'll be fine.

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. According to the research of modern scholars, it is considered that the trace of Huang family in this edition is the intrusion of Taoist priests in Sui and Tang Dynasties. Its basic material comes from the long-term observation of life phenomena in ancient China, a lot of clinical practice and simple anatomical knowledge.

Huangdi Neijing laid the foundation of human physiology, pathology, diagnosis and treatment. It is a medical work with great influence in China and is called the medical ancestor.
