Abstract: Li Gou, a scholar of no equal of his time and later generations' model of learning, did leave many shining ideological treasures to futurity. It is our duty to explore the source and sequence of his academic. Li Gou studied Confucianism focusing on practical application, discarding its dross part and learning from the essence, instead of briefly copying and completely denying. Li Gou was influenced by the Confucianism, but was limited in some aspects.
