Put up posters at school. Why?

Netizen taoqi9209 13, hello! I hope my legal knowledge can help you.

After reading your question, I think you worry too much. As long as the places you post are not some wall boards and billboards that are prohibited from posting, or the propaganda content you post is not prohibited, at most, you will violate the school rules, give a warning and ask for cleaning or restoration.

However, since it is at the gate, the school will not let you post it out of consideration for the campus environment. If necessary, please do it in the publicity area.

I hope my answer can help you!
