There is no separate toilet, and there is only one public toilet on each floor. Outside the bathroom is a sink, which usually washes clothes or something, but this is the third phase of the dormitory. I don't know about the fourth issue. It should be the same. The lights in the corridor are on all the year round, so don't be afraid of the dark ~
A small room for four people, a public toilet on the first floor, is similar to a general dormitory, and it is more convenient to communicate with classmates. After living for four years, I feel that the only biggest drawback is poor ventilation, poor quality or troublesome hygiene.
