In recent years，the issues concerning “new agriculture，rural areas and farmers” such as “hollowing out rural areas，marginalizing agriculture and aging farmers” have appeared in China. As a result，rural grass-roots organizations have weakened to some extent. This contradiction is more prominent in the relatively underdeveloped western region. At present，from a practical point of view，Wechat is widely used in the practice of social governance in order to achieve better results in the management of rural grass-roots organizations. Focused on Ningxia，the project team found that new media brought new means to the development of rural grass-roots organization management through participant observation and off-line interviews with rural Wechat groups. Rooted in the grass-roots rural areas，there are active information dissemination，frequent interactive feedback and rich information dissemination，organization，mobilization functions had been found in these Wechat groups which rooted in the grass-roots rural areas. We also found that members of these Wechat groups showed new media literacy to a certain degree. These bottom-up groups also showed the characteristics of loose management and abundant and miscellaneous forms of information dissemination. We also found that informal communication within the natural system has constructed a good communication environment in a certain sense，made up for the shortcomings of formal organization dissemination，and helped to build a new type of grass-roots organization communication network.
