One: In order to make rational use of resources. The reason why schools do this is nothing more than to make rational use of resources. It is always impossible that because there are few boys, only half of a dormitory is occupied and the other half is empty, while the girls' dormitory is full. This phenomenon is quite common in universities. However, the floors of girls and boys are generally separated by iron gates, and there are also special people to take care of them.
Two: the elevator caused controversy. In Beijing Normal University, the controversial issue is the use of elevators. It turns out that the bottom three floors of a dormitory building are for boys and the fourth floor is for girls. However, because girls are embarrassed to meet boys in the elevator when they take a shower and wear pajamas, girls say that only boys on the third floor don't need to take the elevator at all, and they can use it under special circumstances. This idea aroused the dissatisfaction of boys, who thought it was sexism. The argument in the group was inconclusive all night.
Three: the problem remains to be solved. In fact, such problems need to be solved by schools. Although we are all highly educated students, we still can't confirm our personality. If boys take the elevator, they can easily enter the girls' floor. In case they really meet abnormal people, it will cause trouble to girls. We often see such things, and it is not groundless.
The end result of the matter is that the elevator stops running. Boys don't want girls to use it, and girls don't want boys to use it, so everyone has to use it.
