I've been teaching in China for 20 years. All levels. My last 6 years in high school yes the kids some all day at school, some from 4pm Sunday to 3.40 Saturday. Then they can go home. Are the happy? No. They are much more aware then shown. It's common student live at school, but what is honest it's for education. It's because b parents push them. They aren't happy and this show is a farce.
