Abstract: The supporting system of rural left-behind elderly includes self-support based on farming or livestock raising，descendant-support based on younger generations，and social-support based on welfare system. “Home care”is still the most popular old-age care model that fits in the needs of left- behind elderly in rural China. At present，the base of“home care”relying on self and descendant support is declining gradually，while social support is still quite limited. Through redefining the social role of left-behind elderly，we found that they are not“wasted lives”，but important foundations for the countryside. The supporting system of rural left-behind elderly should include a welfare system based on the concept of“sharing”which helps them obtain the deserved part from social wealth; a medical system based on the concept of“big health”which provides more effective health cares; and the cultural system based on a“bottom-up”concept which makes them better enjoy their life.
