However, if you want to apply for a school, you usually apply to the counselor of your department and the teacher who is in charge of the dormitory. Then he will contact his aunt who is in charge of the dormitory to see if there is any vacant dormitory. If there is, you can live in it. Teachers are generally reluctant to correct it for you at first. You must have a legitimate reason. Students generally don't like poor dormitory conditions, and teachers want to change dormitories. They all want you to mediate. The teacher's task is to teach students, so if you communicate with the teacher, you can change.
