Many young people in rural areas are trying to reduce the burden on their families in order to make a living, and they all go out to work, leaving only the elderly, women and children at home. Women and children of left-behind elderly people have always been a topic of social concern. For the problems of life and old-age care for the left-behind elderly, China should give them enough old-age insurance system, which can be balanced with the urban old-age insurance system, give them some help in life and give them psychological peace of mind. Many left-behind elderly people can still work in the fields, but they can't sit still at home. They always have to work in the fields and grow some vegetables, which can also reduce economic output and reduce the burden on their children. Old people always think of their children. An old man left behind should care more about the government or local cadres in the village, walk more and care more.
