It's best to settle, talk to the class teacher and say it won't happen next time.

Because it belongs to truancy, you should record it.

But one month is too long to delay the course in the third grade.

If the head teacher is really bad, pretend to be 13, and then tell the head teacher to go to the Education Bureau, or if he doesn't agree with you to go to school, he will really report it to the Education Bureau. If he can't get through, he will go to the police coordination bureau.

If you run into a wall everywhere, simply talk about your own affairs in detail, attach photos of the school and the class teacher, and send them to Baidu Post Bar, preferably World of Warcraft, which is easy to get angry. This is a last resort, because the influence of using online public opinion is great, but the risk is also great.
