"God" is an extremely important aesthetic category in the history of ancient Chinese painting theory, which originates from its fundamental connection with the philosophy of pre-Qin and Han Dynasties, and the metaphysical Buddhism of Wei and Jin Dynasties. In Wei and Jin Dynasties, "God" broke the barrier of bone study in Han Dynasty, expanded from figure painting to landscape painting, changed from the god of object to the god of subject, and then evolved into aesthetic needs. In Sui, Tang, Song and Yuan dynasties, "God" entered the field of painting criticism and became the grade and standard for evaluating calligraphy and painting. In Ming and Qing Dynasties, "God" turned from the external world to the combination of subjective and objective, expanded and sublimated continuously in the combination of changes, and finally jumped to one of the core categories of painting aesthetics. Calmly examining the category of "God", it is not difficult to find that its emergence is not created or constructed by one person, but the result of the joint efforts of philosophers and painting theorists in successive dynasties. The use of "God" is very extensive, its main points are as follows: the description of the object; The inner spiritual nature of the work; The creative subject's spirit, soul and artistic thinking activities; The highest level of artistic creation. "God" contains multiple meanings in the history of Chinese painting theory. It is the unity of god of subject, God of object and God of subject and object. Its aesthetic purport is mainly embodied in four aspects: god meeting, spirit thinking, spirit charm and spirit environment, which is helpful to promote the expression of local art criticism.
