The application and popularization of mobile Internet in rural society gives birth to the transformation and upgrading of rural governance model,and also expands the public space of rural society. The case analysis shows that the WeChat group of the cadres and the masses is actually the realistic mapping of the public communication space and the public governance space in the rural society,and the interaction,convenience and transparency of the Internet expand the breadth and depth of this dual space. The virtual community created by WeChat Group provides an opportunity and platform for villagers to interact and help each other. Rural publicity reunites in “micro-communication”. Meanwhile,the “micro-self governance”,mainly characterized by the “micro-management,micro-supervision,micro-decision and micro-service”,strengthens the subjectivity of the peasants in the rural governance field. At the same time,the dual role of village cadres is also substantiated in the virtual space shaped by WeChat group,which makes the “national presence” and “rural autonomy” tangible in the space,thus strengthening the complexity of rural social public space.
