Hello, I am from this school. You are allowed to go in, but if you want to visit Tuanhe Campus, you should sign a visitor list when you go in, and sign the name of the classmate you want to meet, your name and contact number, but if you talk to the security guard for a while or promise to come out immediately, they will still let you in. But you don't have to sign any notes when you enter the Muxidi campus. However, Tuanhe Campus has good hardware facilities, large campus and is spectacular, so it is worth visiting.
