Nanjing University has "access control", so anyone can enter by swiping their card. Should the doors of colleges and universities be opened?

Brush access control is for campus safety. I support this, because there are too many foreign tourists now. No one has specifically checked this aspect.

The risk is extremely high, especially near the girls' dormitory. In many school dormitories, there are always perverts who expose their reproductive organs on the roadside and steal women's underwear from the dormitory, but this can only play a certain role. Management needs to be strengthened. It is best to equip a campus with several instructors, strengthen management and patrol the campus frequently. After all, ordinary safety problems are not strictly controlled by instructors.

If colleges and universities open their doors, they must strictly manage the campus, otherwise how to ensure the safety of students?
