The complete works of health care in Huangdi Neijing are divided into two chapters: Chapter 16, which includes the knowledge tree of oriental medicine, life, age, health care, unique health care concept, "three treasures" of health care, the theory of Jiankang Palace, and the theory of human "Internet"-meridians. It is a wonderful book that combines China's traditional philosophy with medicine, and integrates the way of keeping in good health, medical skill and longevity that a hundred schools of thought contend. Its unique "Chinese-style" health preservation theory has been widely used so far. It fully embodies the unique understanding of the ancient Chinese people on the relationship between the human body and the four seasons, and the overall concept that all parts of the human body should reflect each other. It clearly describes the anatomical structure of the human body and the operation of the whole body's meridians, and deeply and comprehensively discusses human physiology, medical pathology, medical geography and medical phenology.
