Abstract: It is a distinctive feature in the process of the establishment of the CPC to take the benign interaction between the grass-roots political power and the public as the starting point and make the masses participate in the political life spontaneously. Through the analysis of the operation of the political power in Bishan County, we can find that the process of the operation of the political power in Bishan County has a strong positive interaction with the local people. It is in this benign interaction, so that Bishan county can quickly complete grain suppression bandits, rent reduction and return to detain and other important historical tasks, so that the follow-up land reform, production and construction work can be launched smoothly. The logic of political power operation in Bishan County also indicates that the construction of grassroots political power in southwest New Area is to some extent completed by the integration of mass line and united front policy.
