Ge Hong: I am the main founder of Waidanology

Ge Hong was a Taoist thinker of the Eastern Jin Dynasty who made some significant contributions to the promotion of Taoist theory, and his Waidan theory was mainly manifested in his book Baopuzi Inner Chapter.

Baopuzi

First of all, based on the theory of Yuan Qi, he believes that all things in heaven and earth are born of one qi, and change is the natural nature of heaven and earth, and people can promote the feasibility of change through efforts. Secondly, he followed Wei Boyang's path and believed that since people are born of qi, then people's life and death directly depend on the strength of qi and its changes, so "how to nourish qi" has become his primary problem. In response to this problem, he developed a set of cultivation theories that spit out the old and accept the new. Finally, it is difficult for people to keep the vitality of their endowments in life, so he pays attention to the question of "how to refine the golden dan to make life last forever". In response to this problem, he tightened the medical theory of the alchemists at that time and developed the foreign dan science of "pretending to be self-reliant by external objects".

Because he placed Taoist immortalism on the basis of scientific and experimental significance, he became the main founder of the Taoist Theory of Waidan.
