Class A: 2500/ school year; Class B: 2 100/ school year. Every dormitory in Class A has a bathroom. Class B dormitory is public, with 2 bathrooms on each floor (each bathroom has 4 places for defecation). Only building 1 is a class A male dormitory, while buildings 2, 3 and 4 are class B male dormitories. However, the ventilation in 1 building is not good, and it is not good to dry clothes or anything. Also, if 1 roommates defecate in the morning, you will be in trouble if you want to brush your teeth, wash your face or defecate. Although classes started at 8: 30 in the morning, everyone got up late and the time was tight. So I suggest living in class B dormitory.
