Not in theory, but it depends on the management of each school. At present, there is no explicit stipulation in the school that domestic workers are not allowed to enter the dormitory, but you can report it to the guide and then to the dean. If handled well, we should be able to knock on the door of entering and leaving the dormitory and try our best to improve their quality. Generally, there are more than two people in and out, and so on. But it is generally impossible to ban entry. After all, the dormitory is in their charge, justified, and there will be a big hat-for your sake!
