Doctoral students should theoretically live in a new building, a single room, a living room for two people, a bathroom, a shower, hot water at night, a public washing machine and a place to put hot water. The conditions are great. But the current situation is that the new building is full, freshmen can only live in the old building, and then the old students move to the new building in turn according to the grade order after graduation. The structure of the old building and the master's girl building is the same, except that there are two people in each room.
