The ontology thinking is an important academic method which plays a leading part in wangbi's philosophy system.Wangbi applied the academic method to Laozi Annotation,Zhouyi Annotation and Interpretation Of Analects,to rethink the relationship between the instinct law and external emotion of human being.He suggested‘xing should predominate qing 'and advocated ‘the sage contain qing',which made the sage get rid from the bondage of god,and appear in front of common people with a living posture.
