1, the concept of wholeness is Chinese medicine's understanding of the wholeness of human body and the unity of internal and external environment. The holistic concept of TCM is mainly embodied in the wholeness of human body and the unity of man and nature. Therefore, the connotation of the whole concept is that the human body is a whole, and man and nature are unified with each other.

2. Traditional Chinese medicine refers to a comprehensive science that focuses on the theory and practical experience of traditional Chinese medicine and studies the transformation law of health and disease in human life activities and its prevention, diagnosis, treatment, rehabilitation and health care. Guided by the theory of Yin-Yang and Five Elements, TCM studies the physiological and pathological pharmacology of human body and its relationship with the natural environment from the perspective of dynamic whole, and seeks the most effective methods to prevent and treat diseases. Any theory, if it does not have the characteristics of the overall concept, is not a complete sense of Chinese medicine.

3. The theory of TCM comes from the summary of medical experience and China's ancient thought of Yin-Yang and Five Elements. Its contents include the theory of essence and qi, the theory of yin and yang and five elements, qi and blood, body fluid, viscera and meridians, constitution, etiology and pathogenesis, treatment principles, health preservation and so on. As early as more than two thousand years ago, the monograph Huangdi Neijing came out, which laid the foundation of traditional Chinese medicine. Today, China's theories, diagnosis methods and treatment methods related to traditional medicine can be found in this book.
