Boys and girls living in separate buildings can greatly reduce unnecessary troubles and embarrassment. As the saying goes, men and women don't kiss. Although it has been 2 1 century, people's minds have been opened up a lot, but this does not mean that we can abandon or weaken the idea that men and women are not close. The basic moral bottom line needs to be adhered to forever.
It will bring a lot of inconvenience for boys and girls to live in one building. For example, everyone is used to wearing pajamas in the dormitory, and some styles of pajamas are often a little exposed. So, imagine, when everyone walks out of the dormitory room in pajamas like this, wouldn't you feel a little embarrassed if a classmate of the opposite sex who lives in the same building passes by?
Boys and girls living in the same building can effectively reduce the probability of crime to some extent. Nowadays, news reports of sexual assault are still endless, and obscenity and sexual assault are still hot topics in today's society. As we all know, most university female dormitories have signs prohibiting men from entering. Why? I think one of the main reasons is to prevent sexual assault and protect the safety of girls.
Of course, if the school has decided that boys and girls must live in the same building, under this premise, girls will be arranged to live in the lower floor and boys will live in the upper floor. The reasonable arrangement is that it will be much easier for girls to carry heavy things upstairs and downstairs. This is to take care of girls, that's all.
