University dormitories are usually separate for men and women. After all, the dormitory is a private space. College students are more casual in the dormitory. Sometimes I go to the water room or laundry room in the dormitory. Because they are all of the same sex, it is convenient for everyone. However, some colleges and universities have implemented "mixed dormitories".

Coeducation is not an exception. As early as before, there was a famous "Yuanyang Building" in Tsinghua University, where boys and girls lived together in a dormitory building. However, the explanation given by the school is beneficial to the relationship between boys and girls. Since then, many universities have tried this policy, such as Beijing Normal University. Even because boys and girls live in the same building, girls find it inconvenient to object to boys taking the elevator.
