Sleep is a serious business for China’s education authorities. Yu Jianwei, an official with the National People’s Congress Internal and Judicial Affairs Department, said that according to a survey, at least 30 million students under the age of 17 have suffered from a variety of emotional and behavioral problems. The number of people under the age of 18 in China is more than 300 million.

    As early as in 1994, the National Educational Committee (the predecessor of the Ministry of Education) issued a document to guarantee sleep for students. On June 1, 2007, the revised law On the Protection of Minors stated that schools and parents must ensure that primary and secondary school students get enough sleep.

    The Educational Ministry regulates the amount of homework students are given and also dictates that teachers are not allowed to occupy students' spare time, including week-ends and vacations, with extra classes.

    In 2008, schools in three districts in Shanghai began asking students to arrive half an hour later, and replaced the original morning reading time with physical activity.

    In addition to Shenyang, many other provinces and cities have introduced measures to ensure primary and secondary school students get more sleep.
