First of all, girls entering boys' dormitories will not pose much threat. Therefore, in this case, the aunt will also pretend to be invisible. So ordinary girls can go into boys' dormitories to advertise, or send out some advertising leaflets, or talk about something more important. In addition, boys can also take their girlfriends to visit the dormitory. Generally speaking, boys will be very welcome and even help their good friends clean the dormitory, leaving a good impression on girls. Therefore, it is also a phenomenon that dormitory administrators really want to see.
Secondly, in ancient times, traditional women in China did not allow strangers, especially boys, to enter their rooms, because it was a private space. Even in some traditional concepts, this has a lot to do with the girl's personal reputation. But now, although we have abandoned the traditional conservative ideas in the past, girls still want their rooms to remain mysterious, so for this reason, girls' dormitories generally require boys to stop.
Third, girls in the dormitory are not dressed as neatly as they are outside, and they are also very comfortable in the room at ordinary times, so if a boy suddenly runs in at this time, it should cause great panic. So not letting boys in can also avoid some embarrassing situations. Under normal circumstances, if some men enter the dormitory, such as some maintenance workers or some leaders' inspections, then there will be some teachers' notices in the qq group or WeChat group of the dormitory to let the girls dress neatly and avoid this embarrassment.
