Oh, my God, how did this happen? Anyway, what I meet now is that men and women don't live together. In all my universities, boys and girls live separately, and there are several buildings for boys and several buildings for girls, all of which are clearly divided. And every building has an aunt in charge of order. Of course, boys can't enter the girls' dormitory, and girls can't enter the boys' dormitory. This is a special rule. Unless there are boys or girls among the students who check the hygiene. You must get your aunt's permission to go in. There is another special case, that is, the brothers who deliver water. We all call him Brother Shui. He delivers water in our building and can enter and leave the boys' dormitory and girls' dormitory at will. Besides, no one, including students' relatives and friends, can do it. I don't know if we are strict here, but I really haven't seen men and women living in dormitories. As for what you said about men and women living in dormitories, I feel very embarrassed. I think this kind of thing is like boys and girls using the toilet. In this case, aunt lodger has no meaning of existence. I still remember one time, my brother and I came back from other places to go to school. I brought back a heavy box, but I live on the sixth floor and there is no elevator. My brother said, you tell my aunt that I'll take your box to the sixth floor and then come down. But the aunt in charge of the house disagreed. She said as long as boys were not allowed in, and then I dragged the oversized box to the sixth floor in great pain. I don't even know how I got up there. My brother also said, should I take a rope from it to hang my box? Finally, forget it. However, I think it is good for menstruation to be strict with this matter. It is also to ensure the safety of our girls. If men and women live in dormitories, I don't think girls should be so safe. Of course, this is just my idea.
