You are a boy, so let me talk about the accommodation for male graduate students. In the past, girls lived in Room 2 1 above the eighth floor, but after moving to Room 19, they may be moved by boys in Yi Yan. In addition, Yi Yan boys who live below Room 22 on the third floor have already graduated, and it is also possible for them to move in. Room 18 will be promoted to Yansan. There is little chance that you will survive.
2 1 Room 22 is the same type, with balcony, electric fan and security door. One side of the room is a table, and the other side is a bed. There are two toilets and a shower (only cold water) on each floor. If you want to wash hot water, you can only go to the bathroom in front of the canteen. These two buildings are 13 floors, each with two elevators.
Among them, only seven and eighteen buildings have separate bathrooms.
