Abstract: LIU Wansu integrated scientific principles into his theories, drawing from “HUANGDI NEIJING” and “SHANGHAN LUN”. He proposed the theory of “HUORE” with “Zangfu Yunqi”, “Zangfu Shuihuo”, “Liuqi Jie Huahuo ”, “Wuzhi Huahuo”and “Shanghan Ji Rebing”. Additionally, he supplemented the pathogenesis of “Zaoqi” and expanded on the theory of internal and external diseases. For externally induced fever, he believed that the main pathogenesis was Xuanfu Yuzhi, Yangqi Fuyu, and Yangre Yujie. Treatment involved using cold and cool drugs to clear heat and reduce fire. LIU Wansu's approach to treating Rebing became foundational for later developments in this field. Influenced by Liu Wansu's work, there were many academic inheritors who formed an important school in traditional Chinese medicine known as the Hejian school. This influence also extended to ZHANG Congzheng, ZHU Danxi, LI Dongyuan who put forward new theories that promoted the development of what is now known as the Hejian school. The combination of ZHANG Congzheng's theory of Gongxie, ZHU Danxi's theory of Yang Youyu Yin Buzu along with LIU Wansu's theory constituted the main characteristics of this school which set it apart from other academic schools within traditional Chinese medicine.

Key words: traditional Chinese medicine, academic schools, Hejian school, Huore theory, LIU Wansu
