With the development of economics (经济), the problem of left-behind children (留守儿童) has become a serious social problem. More and more people have realized we should do something to help them.

One of the biggest problems is that the children are all hungry for the love from their parents. Many of them can just get a call or a letter from their parents half a year, a year or even several years, which makes some children lost their parents' faces. When they meet their own troubles, they have no one to talk with. Nobody gives them enough care.

Because of being too far away from their parents, the left-behind children's study is the second biggest problem. From a survey (调查) about their study, only two percent of the children get good results, while ten percent of them are common and eighty-eight percent of them are poor. What a pity!

There are also many other problems of the left-behind children, such as having no ability to protect themselves, unhealthy lifestyles, spending too much pocket money and being crazy about Internet and so on.

In a word, to solve all the problems of the left-behind children needs the government, families and schools to try their best together.
