Based on investigation from D village of Songlin Township in the city of Guanghan，this paper points out that villages became gradually hollow in rural areas in Sichuan province since “the Tie of Migrant Rural Labors” in 1990s，also led to gradual alienation of interpersonal relations. At present，on the one hand，because of departure of young peasants from countryside，old people are left alone in the country and they can hardly depend on their sons，on the other hand，old people can rely on community. In recent years many elderly face many problems as following：difficulties in lives，medical problems and missing their sons and grandsons. The solutions to these problems are just as following：first，provide chances for peasants to make money without leaving hometown；second，make chances for children to study in the countryside so that they are passionate towards the community；third，the state should help rural areas；fourth，cultivate community pension mode on the condition of reconstructing mechanism in family pension；fifth，the gradual liberalization of restrictions birth control policy，extend family line.
