title: [Korean doctor Che-ma Yi and his Sasang Constitutional Medicine].
abstract: Tongui suse powon, written by Chi-ma Yi (1837 - 1900), divided people into four types according to their constitution and disposition-Taiyang, Taiyin, Shaoyin and Shaoyang. He discussed the appearance, viscera, temperament and disease each type of people probably have. The formation of Sasang Consititutional Medicine is influenced by Sasang Theory in Yi Jing and 25-mode Personality Theory in Ling Shu and has nothing to do with Huangji Jingshishu written by SHAO Yong.
