Knowledge is composed of three elements：content, competence and state. These three aspects of knowledge are not only intertwined, but also complementary, together forming a complete structure of knowledge. Knowledge learning is a process of internalizing the achievements of human understanding, mastering competencies and cultivating a good state of mind. The learning of knowledge content is a process of obtaining the fruits of human understanding through propositional understanding, content reflection and enlightening application. The learning of knowledge competence is to acquire judgment, discernment and skills developed through activities/actions by means of embodied cognition, tacit inference and exemplary teaching. The state of knowledge permeates or is embedded in the content and competence of knowledge, which can be obtained by appreciating the existential significance of states, arousing enthusiasm for knowledge and cultivating rational beliefs. On this basis, it is necessary to change the traditional understanding of knowledge teaching. Since knowledge teaching is essentially a thick view of knowledge, in terms of purpose, it should be shifted from "knowing" to " ignorance"; in terms of content, it should expand the understanding of subject knowledge and pedagogical knowledge, and in terms of process, it should be in the process of mutual integration between decontextualisation and immersion of the domain.
