800-word composition, the topic is the unity of knowledge and action.

In the third year of Zheng De in Ming Dynasty (1508), Wang Shouren, a psychologist, gave a lecture at Guiyang Institute of Civilization, and put forward the theory of the integration of knowledge and practice for the first time. The so-called "integration of knowledge and practice" is not a general relationship between understanding and practice. "Knowledge" mainly refers to people's moral consciousness and concept. Practice mainly refers to people's moral practice and practical actions. Therefore, the relationship between knowing and doing refers to the relationship between moral consciousness and moral practice, and also includes the relationship between some thoughts and practical behaviors.

Wang Shouren's thought of "the unity of knowledge and action" is: there is action in knowledge, and there is knowledge in action. Wang Shouren believes that knowledge and action are the same thing, and cannot be divided into two parts. Knowing and doing are two words, say it once. From the perspective of moral education, Wang Shouren strongly opposes the phenomenon that knowledge is divorced from practice and "knowing but not acting" in moral education, and it is of positive significance to attribute all morality to individual conscious behavior.
