Dear Editor,
I'm a middle school student. I am writing to tell you something around us.
Nowadays, as the development of China's urbanization, thousands of people move into cities, leave their children at home. However, many of these left-behind children have problems, which always feel lonely or stressed out and are more likely make mistakes. They even behave illegal due to lack of their parents' love and care.
How can we solve a problem? In my eyes, our government should balance the economic develop in different area. Besides, we can organize “hand-in-hand” activities to call on more people to help them. It's very important for us to pay more attention to these children if you want to build in a harmonious society.
Best wishes to you!
Yours,
Wang Qiang
