The art of sexual intercourse is also called the way of Su Xuanzhi, and ancient immortals Motome, Cai Nv, Peng Zu and Rong Chenggong all know this method. Zhang Daoling, the founding father of the Eastern Han Dynasty, once said that it is the law. The road of Su Xuan is one of the immortal panaceas. The cultivation of qi of men and women is very important, because men's external yang leads to internal yin, women's vulva leads to internal yang, and men should become pure yang, so women's innate true yang supplements their internal yin, and women should become pure yin, so men's innate true yin supplements their internal yang. "Shenshenqi" says: "There is no yin and yang in things, which goes against the sky and the elements", so there is a school of double cultivation of yin and yang in Dan Dao, which is another product of pure Dan method. Sexual intercourse has three levels. To the top, self-interest benefits others. Whoever wins will gain and lose. People who go on, harm others and benefit themselves, a trip to the magic road.
