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 isn't only in Beijing. Ji Chunying is a Grade 9 student in Guangzhou. The 14-year-old girl has to get up at 6:45 am on Saturday. Then she has a whole day of classes. On Sunday, she goes to extra classes for math and physics.

But Ji doesn't complain. She says her classmates all work very hard.

Finding time to have fun

Zhao Yang, 13, is from Dalian, Liaoning. As a Grade 8 student, Zhao's weekend is less busy. But he still spends Saturday in school. On Sunday, after finishing homework, he plays basketball. "I feel happy because I still have time to do the things I like," he said.

Some students are much luckier. They don't have to go to school on the weekend.

Ding Yi, a Grade 8 student from Laiwu, Shandong, is one of them. And she's a top student.

During the weekend, Ding usually gets up at 8 am. Then she spends some time doing homework. After that she is free to go shopping or watch TV.

Ding said her mother once wanted her to try extra classes. But when they asked Ding's teacher about it, the teacher said it was unnecessary.

"My teacher said I don't need to push myself too much. Learning well at school is enough," Ding said. "I feel pretty lucky."
