The supporting Yang school started with the analysis of the divinatory symbols of Qian（ 乾）

Kun（ 坤）

Kan（ 坎） and Li（ 离）

the principle of Yin and Yang originating from Kan and Li goes through both the theory and clinical practice. As a result

the view like"life relying on fire"seems a logical corollary. Meanwhile

the innerYang outer-Yin body structure theory takes clues to the essential attributes of Yin Yang movement and the related discourses in Zhouyi（ The Book of Changes

《周易》） and Huangdi Neijing（ Inner Canon of Yellow Emporor

《黄帝内经》） as the support to put forward the new cognition about the relationship of body and function between Yin and Yang

the location of healthy Qi and pathogenic Qi as well as the treatment based on syndrome differentiation.Through the analysis

the researcher finds that the supporting Yang school and the inner-Yang outer-Yin body structure theory are consistent in the basic point of view

both raise that the general law of Qi movement between Yin and Yang is that Yang is bottom-up

inner-outer while Yin is top-down

outside-inside so that they can interact with each other

thus clarifying the current fuzzy understanding in Chinese medicine

which is that Yang is outside and Yin is inside during the interaction.
