The "Notice on Further Strengthening the Sleep Management of Primary and Secondary School Students" recently issued by the Ministry of Education (hereinafter referred to as the "Notice") clarifies that primary school students sleep 10 hours a day, junior high school students sleep for 9 hours, and senior high school students sleep for 8 hours.

It's really interesting, even sleeping should be included in the management. Although this notice comes from the Ministry of Education, I am sure that this notice will be as lifeless as those before!

There are many educational problems, but they are hard to get back. The most fundamental thing is the asymmetry between supply and demand, and the most fundamental thing is that the income and treatment of different types of work are too different. Try to assume that the income of a street sweeper and a civil servant can be roughly equal. Will there be parents who can't sleep? There will be no students who can't sleep well.
