Look at the strict management of the school, it's okay if it's not strict. Tell the administrator that this is a trivial matter. At best, it is easier to manage together. So first you have to tell the floor manager that you want to change it, because you have to check your bed and ask for dessert. If someone wants to change with you, you'd better let them tell you. Second, we should tell the class teacher to ensure that changing dormitories will not change the management of teachers. Third, be firm and don't be coy. This is a trivial matter. If we have a good attitude and a firm attitude, and ensure that nothing will happen, it is estimated that it will be fine.
