There is a group of people called left-behind children in the world.They are very lonely in rural ares because of lacking parental companionship.And this children who stay in rural ares will depend rural development.So we need pay more attention on them.

To pay attention on left-behind children,we not only need more faculty strength，but also need increase parents attention to their children in rural ares.

I hope one day there were no children left behind.All children can enjoy reunion with their parents.
