Hejian’ Theory was flourished in the Dading reign of the Jin Dynasty, while the doctors of the Southern Song Dynasty didn’t know Hejian’s Theory. As Southern Song was overthrown by the Yuan Dynasty, Hejian’ Theory began to spread to the South. Hejian’s descendants, disciples and those doctors studied this Theory personally all contributed to the Theory’s spreading to the South in the Yuan Dynasty. In the meantime, Liu Hejian’s descendants moved to Jiangxi province later as well as those studying the Theory personally also made similar contributions. His disciples, especially Jinshan Futu transmitted the Theory to Luo Zhiti, then to Zhu Danxi, all contributed to the southward diffusion too. The local medical officer who inherited the Theory expanded its influencing area. The inheritors’ medical theory was not just limited to Hejian’s Theory only, reflecting the academic progress at that time.
