Do teenagers in small villages（村子） do chores at home? How about the teenagers in big cities? Here is a survey（调查）. 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（村子）. We made a diagram（表格） of the result（结果） of our survey（调查）. Let’s have a look at it. We found out that teenagers from small villages do more chores than those from 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.
