It's hard for you to convince them.
You have to understand, 1, first of all, changing dormitories is definitely not a casual move. There should be a comparison at this time.
2, no one wants to suffer, in the final analysis. No one wants to give up vested interests, not everyone thinks so.
It can only be stirred up by two people in a dormitory. And guess together.
Do you have the right to change bedrooms? If there is. You just need to decide what you want. Not if you don't want to. You should have authority.
If you don't have this, then this is not what you should worry about. Give it up.
