There are good and bad dormitories in Xida University, including four rooms and eight rooms. Some new dormitories have a better environment, and the old ones may be almost the same. Dormitory allocation is decided by the college. You can ask the seniors of your college about the dormitory allocation in your college this year. This is a clear point. You can't choose for yourself. If you really don't want to live in a good dormitory, you can discuss it privately with your classmates before applying for a dormitory change, otherwise you can't change. You can also rent a house outside.
