Abstract: LI Fuhai, my teacher, inherits the theory of Shi in the north advocated by LU Zhizheng, a master of traditional Chinese medicine, and the thought of Yishui school. In treating Shi in clinical practice, he takes the theory of Liujing as a whole, combines the Zangfu, attaches importance to the problem of Taiyin and Yangming, takes Piwei as the center, “holds the central position and transports the four sides”, and at the same time “delights in emotions and adjusts Shengjiang”, and gives full play to Yishui school's “opening Guimen, cleaning Jingfu”.

Key words: LI Fuhai, Shi, Yishui school
