Teacher? Teacher Qiaozhong won't help you cut your hair, but sometimes the school will contact the technical college. If you don't pass the exam, you will go out and ask the "master" to cut your hair.

But not during military training, at least after class. But most of them will give a warning or deduct points first, and then the class teacher will write a note asking you to ask for leave to get a haircut. Senior one is strict, and the director of Huaqiao Middle School sometimes gets mad and gets used to it.
