Most people work or study from Monday to Friday. The weekend is usually a time of rest. But today's Chinese teenagers can hardly rest during the weekends.
According to a survey, 24% of the Grade 8 students in Beijing have classes at the weekend. Over 40% of the middle school students have less than eight hours' sleep each night because of study.
And this doesn't happen only in Beijing. Ji Chunying is a Grade 9 student in Guangzhou. The 14-year-old girl has to get up at 6:45am on Saturday. Then she has classes all the day. On Sunday, she goes to extra(额外)classes for math and physics. But Ji doesn't complain. She says her classmates all work very hard.
