It is said that the Buyi Hou health porridge house originated from a legendary story: Yue Xiu, a young boy after Buyi, loved poetry books since childhood and learned martial arts from two strange people in Wulin. By chance, Yue Xiu was involved in the murder of the seven princes' favorite concubine, thus uncovering a huge plot to usurp power and seize the country. In the complicated and confusing Jianghu and court struggles, Yue Xiu's extraordinary performance won the respect of the emperor of the dynasty. The emperor tried to make him an official and a knighthood several times and entrusted him with a heavy responsibility. However, Yue Xiu, who has no intention of pursuing a career, asked to live in seclusion in Huangshan Mountain and devote himself to studying medical skills and health preservation. One is to be immune, and the other is to give alms to the poor.
