Whether a closed university confiscates mobile phones depends on the school rules of your university. Generally speaking, closed schools will confiscate mobile phones.

Before class, the teacher will take out the mobile phone bag and put it in the mobile phone bag according to the class seat. After class, students will take back their mobile phones in turn. Students are not allowed to play with mobile phones in class. If a student violates the regulations, teachers of all subjects will contact your counselor for criticism and education.
