There are nine kinds of people-physical fitness identification and health preservation.

Due to the strength of innate endowment, the thickness of food smell, the difference of orientation and topography, and the difference between the rich and the poor, individual differences are caused. Therefore, Chinese medicine attaches great importance to the analysis of different human characteristics and classifies physique from many aspects. 1. Classification of Yin and Yang and Five Elements "Twenty-five people of Yin and Yang in Lingshu" classifies people's physique into five types according to their body shape, personality characteristics and adaptability to seasons. Compared with ancient music scores, each type is divided into five categories: horn, emblem, palace, Shang and feather, totaling 25 kinds. 2. Classification of too little yin and yang This physical classification is based on the number of yin and yang in the human body, combined with posture and personality characteristics. Lingshu Tian Tong holds that the yin and yang of human body can be divided into yin-exuberance, more yin and less yang, more yang and less yin, yang-exuberance and balance of yin and yang, thus dividing human body into Taiyin people, Yin people and Sun people. There are five categories: people with less yang, and people with peaceful yin and yang. 3. Classification of Nine Constitutions of Modern Chinese Medicine In recent years, on the basis of summarizing the previous experience, the classification of nine constitutions of Chinese medicine was put forward from the clinical point of view, which has important reference value for clinical syndrome differentiation, prescription inheritance and disease prevention. (See the first part-TCM Constitution Classification and Judgment Self-test Table and TCM Nine Constitutions Identification and Nursing) 4. The images and numbers of gossip are inseparable and integrated. As the oldest easy-to-learn language, image number is used to explain various natural and social phenomena in the universe, and it is the carrier of enriching cosmic information. Eight diagrams and five elements each have their corresponding body parts and acupoints. In fact, to explore human physique with the image of gossip is to foresee the physical quality and health status of human body. For example, Gangua people should be cool and moist, and Kungua people should pay attention to wind and temperature to keep fit to cope with spleen dampness, especially in summer, they must open more windows to let moisture out of the room; People who deviate from divination should keep healthy at low temperature. Without hexagrams, it means that Yang fire yang is hot, and heat easily hurts Yin, leading to yin deficiency. Therefore, people who are away from fire should pay attention to energy conservation in winter. Mastering the physical types of gossip, its value is also reflected in: from the understanding and application, learn to adjust yourself, and really take the initiative of health and longevity in your own hands.
