Do teenagers in small villages do chores at home？ How about the teenagers in big cities？ We make a survey last month. We asked 4，000 teenagers in China several questions. Half of them come from big cities like Beijing， Shanghai and Guangzhou. The others are from small villages. We made a diagram of the result of our survey. Lets have a look at it.
　　We found out that teenagers in small villages do more chores than those in big cities. Maybe it is because they live a harder life. Our advice to parents in big cities is that parents should give their children some chores to do. Doing chores teaches teenagers to take care of themselves.
