The transformation practice of Yangquan Mining District from the traditional community structure (unit system) to the modern community structure (community system) is an example of the Chinese Communist Party's "party-organized society". The logic of its theory and practice stems from the fact that the Communist Party of China is a mission-oriented political party that is highly embedded in the social organism. It is also a political party organization that leads and shapes society. The Yangquan Mining District's governance practice of reshaping grassroots communities is a practice of the Communist Party of China's theory of "party organizations organize society." The experience of Yangquan Mining District proves the principle of party theory in a party-dominated country: the integration of political parties into society lies in integrating and organizing society. In the process of integrating society, the political party leads the society, thereby achieving the integration of the political party and society. The theoretical significance of community reconstruction in Yangquan Mining Area is that it provides an empirical research sample for enriching and developing the national governance theory of "party organization of society"; its practical significance is that it provides a reference, mature and complete policy practice sample for the modernization of urban grassroots community governance.
