There is something wrong with the answer of1l. I am in Grade 08. Military training lasts about two weeks, and there will be a day off on New Year's Day. Hair must be cut, the requirement is that you can't show your hair after wearing a military cap, and you should shave it short. The military training time is after the final exam of the first semester of freshman year. Don't keep your hair warm. Winter in Guangzhou is cold in the morning and hot at noon. During military training, I have to get up early every day. It was very cold at first, and then it was very hot near noon. . . If you don't cut your hair, the instructor will force you to do it. After all, it's all about reunification in the end.
