Doctor Huang Yuanyu put forward a special medical thought that the earth element is the dominant element and controls other four elements so that Qi can cycle in the body. Based on classical literature of Confucianism and Taoism, this research tried to find out the formation of Huang’s academic thought. The following has had fundamental influence in shaping Huang’s academic thinking: Hetu Luoshu’s biological transformation, the five circuits and six qi as well as qi dominant transformation in Huangdi Neijing (Huangdi’s Internal Classic), the idea of Xiang and Shu in Yi Jing, the thinking of earth as mother in Dao De Jing
