Abstract:Five states is five types of people based on their contents of Yin and Yang, including types of Taiyin, Shaoyin,Taiyang, Shaoyang and equilibrium of Yin and Yang. The "five-pattern personality test" is established on this foundation and is one of the landmark achievements of TCM psychology. Since there has no relevant discussion on the relation between the five elements and five-pattern personality, the author went through the literatures and conducted some deep thinking, mainly from the aspects of inner essence of five-pattern personality and external characteristic to discuss its relation with the five elements. The conclusion of this paper is that Shaoyang corresponding to the wood, Taiyang corresponding to the fire, equilibrium of Yin and Yang corresponding to the earth, Shaoyin corresponding to the gold, Taiyin corresponding to the water. The purpose of this paper is to supplement and enrich the theory of TCM psychology, and constitute the theory basis for the syndrome differentiation in clinical practice.
