Abstract: As a Taoist theorist, medical expert, and health expert during the Wei and Jin dynasties, Ge Hong's medical body view is mainly included in Baopuzi, especially in Neipian which fully demonstrates Ge Hong's medical body view, and is an important component of the development history of medical body view in China. Ge Hong takes "Xuan" and "Dao" as the ontology, connecting all things through the matrix of "One", forming a cosmic biochemical model of "Xuan, Dao—One—All Things". He incorporates the body into this biochemical system, believing that the human body is born from "Xuan", "Dao", and "feeling Qi". He constructs the medical body model of "Qi, Body and Spirit", emphasizing both body and spirit; Ge Hong believes that "the length of my lifespan depends on me" and forms a body care concept based on the premise of "no harm, no damage" to the body, and "my life is determined by me, not by heaven". He integrates this care concept into every aspect, from daily life to governance, all of which are possessed; the idea of "not changing the old body" and "immortalization not dying" has constructed an ideal realm of infinite life for the body, with profound connotations and rich connotations. Ge Hong's medical body view has a profound impact on the construction of Chinese medical body view, and has a wide-ranging influence on Chinese medical theory, disease prevention, health care, and more.
