This thesis aims to propose a "instrumental interpretations" to Wang Bi's theory of "Zi Ran and Ming Jiao" as following: 1. Chong Ben: Wang Bi's ultimate concern is the restoration and preservation of Human nature, believing that "Wu Wei" is the only method; while "You Wei" induces deceitfulness and destroys human nature. 2. Ju Mo: one of the dimensions for "Ren Yi Li Jiao" to be "Ming Jiao" is to restore Human nature after being corrupted. This is the value of "Ren Yi Li Jiao." 3. Xi Mo: opposite to "Ming Jiao," "You Wei" must be abandoned for it not only destroys human nature, but also distorts the meaning of "Ren Yi Li Jiao."
