Interpretation of Taoism: The progress of medicine in Qin and Han Dynasties directly promoted the development of Taoism. At that time, we had a general understanding of the structure and function of human organs. In Huangdi Neijing, a famous medical work in the Western Han Dynasty, there are some sayings, such as "every tendon belongs to the knot" and "the chest and abdomen are the Guo Ye hiding the abdomen". This refers to the human body structure.

Health guidance:

The application of guidance in health preservation has also made new progress. Many people in Laozi School and alchemists actively take guidance as a means of health preservation. For example, in the early Han Dynasty, "I want to abandon personnel and walk in red pine, but learn to avoid the valley, lead the way, and be intellectual" ("Historical Records, Stay with Hou Shijia"); Li, Li, Li and others use "guiding qi to nourish nature"

The wind of "guiding and nurturing" prevailed in the Eastern Han Dynasty and the Western Han Dynasty. Many alchemists mentioned in the Book of the Later Han Dynasty are good at guiding health preservation. These people have undoubtedly contributed to the development of guidance, but their purpose of "guidance and training" is to hope to live forever. Therefore, some mysterious things were also mixed into the guiding spirit that was popular at that time.
