Fu Xingjue is a lost book of Traditional Chinese Medicine (TCM) prescription written by Tao Hongjing of Liang dynasty. After being donated to the China academy of Chinese medical sciences in the 1970s by zhang dachang, a TCM folk doctor, it was salvaged and published by experts such as Wang Xuetai and Qian Chaochen. All versions at present is the manuscript. Fu Xingjue referred to many contents of the Tang Ye Jing Fa written before the Han dynasty, and is accompanied by a key schematic diagram, that is, the “Tang-Ye-Jing-Fa perspective”. Under the framework of the Zang-Fu Xu-Shi theory, the “Tang-Ye-Jing-Fa perspective” described the composition principle of TCM and the treatment methodology based on the Five Wei theory including Pungent, Salty, Sweet, Sour, Bitter and their cooperation according to the syndrome differentiation. It is also called the diagram of five Wei filling and purging body. The structure of the whole diagram is neat and symmetrical. Its logic and rigor are better than the relevant contents recorded in the “theory on the method of storing qi” in the Huang Di Nei Jing. The formula in Fu Xingjue and the twelve prescriptions in Chu Fang Zheng Fan were able to explained accurately by this diagram, which is also closely related with Shang Han Za Bing Lun of Zhang Zhongjing. This paper introduced the historical origin and composition structure of the “Tang-Ye-Jing-Fa perspective”, analyzed its application mode by taking the formula in Fu Xingjue and the twelve prescriptions in Chu Fang Zheng Fan as an example, laying a foundation for the comprehensive research and recovery.
