How can there be such a good thing? Our school is not so humanized. Lights out at night 12. Don't turn off the lights for one month at the beginning of school and one month at the end of school.

Because at the beginning of school, everyone is still busy taking care of dormitory and other things, and by the end of the year, it is time to work overtime to prepare for the exam. So there is electricity all night in these two time periods. The rest of the time 12 power failure.
