2. Where can I put my luggage? Put it wherever you like, and wherever you have time. There are no rules. The wardrobe in the dormitory is very small, so clothes can only be folded inside, not hung up.
The storage box can be put under the bed, which is what I did.
This question is a bit abstract. Anyway, the dormitory can be made clean and tidy as long as it is properly placed. Dormitories generally don't feel crowded.
Note: The above situation does not include 1 No.2 building. These two buildings were newly renovated last year, and the interior of the dormitory is different from other buildings.
