     In a 2005 survey of 2005 schoolchildren in six cities, including Beijing and Shanghai, it was found that

about 77% of them were short of sleep. Should school hours be cut? In new survey taken by the China Daily

website, almost 70% of the 1, 133 people online agreed with cutting school hours, while 20% disagreed and

10% gave no answer.

     Liu Xing (12-year-old, 6-grade student): I get up at 5:50 every school day, have breakfast at 6:15, leave

home at 6:30 and, after a 30-minute bus ride, arrive at school at 7:00, a full hour before lessons start. Besides,

I spend my weekends taking classes in math and English, as well as learning to play the piano.

     Wang Qun (Liu Xing's mother): My son is still no t doing enough to win a place at a top high school, as it

is so competitive. They want students with good English and math and also special skills.

     "Craig" (netizen): The best way for children to learn is through play. Through play, they can develop their

characters, learn to be independent and improve all kinds of skills.

     "Skylark" (netizen): Young parents have little time to play with their children, so letting them go home early

is not a good idea. I think schools should have more activities for children after class.

take time to change people's traditional mind that going to college is the only way to a good job.
