Take precautions before they happen, don't wait until you are terminally ill to seek medical advice everywhere. Modern quotations also imply that we should be prepared to do things.

From: Huangdi Neijing from pre-Qin to Han Dynasty.

Therefore, the sage did not cure the disease, but did not cure it. Husband's illness became medicine, and chaos became a cure. For example, it is not too late to cross the well and fight for the cone.

Therefore, the sage does not wait for the disease to happen, but treats it before it happens, just as he does not wait for the disorder to happen, but treats it before it happens. If the disease has occurred, it must be treated, and the disorder has already formed, it must be treated. It's like digging a well in the face of thirst, and it's too late to make weapons after the war.

Extended data:

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 in 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 traces of Huang family in this edition are invaded by 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.
