Abstract: The existing research mainly researched the way to handle the idle farmland in terms of policies and laws, but ignored the importance of empirical research. Empirical research indicates that some villages handled the idle farmland by mutual-help among villagers. Researching on the mutual-help among people in G village who went through three evolutions, i.e., from economy-dominated relationship to paternal line-dominated relationship and then to neighborhood-dominated relationship, found that the current pattern of its mutual-help is neighborhood-dominated because of their homes or farmlands are adjacent, which is a temporary mode of agricultural production to overcome the shortage of rural laborers. However, there are still a lot of problems caused by less education such as villagers' unwillingness to participate, relatively backward production technology and un-sustainability of mutual-help, which can be solved by guiding the villagers with the help of village party committee, village committee and enterprises, purchasing education services, and resolving disputes with the help of township mediators.
