Dormitories in Xida University are basically different in the same major and different grades, so I don't know how to arrange them in the school now. The width of the bed in Xida University is 90cm, so don't worry about the length. When buying a mat, just buy one with a width of 90cm. If you can't find it, you can sell it in the dog cave of Nishionishi campus, the vegetable market of East campus or the supermarket of the school. Don't worry.
