In the process of spreading and learning the art of crossing the valley, Taoist once wrote a monograph on crossing the valley, and discussed and expounded the methods of crossing the valley. "Bao Puzi's Inner Chapter and Prospect" records three volumes of Xiuliangjing. A Brief Introduction to Tongzhi Art and Literature records a volume of Taiqing Broken Valley Method, a volume of Supreme Broken Gu Dao, various broken valley methods of Taiqing Classic, and a volume of Stop Kitchen Circle (or Pill) Formula. "Orthodox Taoist Classics" contains a lot. However, the contents contained in the book can be summarized into two categories: "persuading people to avoid the valley" and "taking medicine to avoid the valley". (2) "Taking medicine and avoiding food" refers to taking medicine and food. There are many prescriptions, such as taking beans, dates, flax (sesame), chestnuts, crisp, poria cocos, Polygonatum sibiricum, asparagus, ginseng, honey and so on. High nutrition, slow digestion, making into pill paste, and taking orally 1-2 instead of granules after crushing. One formula is high in nutrition and difficult to digest. After a full meal, it will definitely break down and can be used for a long time. Another is to eat rice and then support what you eat with medicine. It is said that it can break the valley for three years. Others use herbs to cook certain stones and eat them.
