"Opening and closing the pivot" first appeared in "Huangdi Neijing, Suwen, Yin and Yang Clutch Theory", which describes the understanding of the transformation of meridian qi, the opening and closing of all things, and the transfer of internal organs from the three yin and three yangs. "Wuchi" as the name of the disease first appeared in the "Medical Sect Jinjian". By explaining the etiology and pathogenesis of Wuchi, the author believes that the mechanism of its pathogenesis is mainly that the "block" of Yin is too much and the "pivot" of Shaoyin is too much, and by analyzing the relationship between the two, we can more comprehensively and accurately carry out better clinical differentiation and treatment of the current disease.
