There are apartments and non-apartments in a quadruple room, which is the difference between a separate bathroom and a public bathroom. The public toilet is very clean, cleaner than my dormitory, because my aunt cleans it every day. The dormitory space is relatively large, for example, the 356th floor is large enough to put a ping-pong table in it. The price is about 1500, I forgot. If the air conditioner is turned on, 200 yuan/year will be charged additionally.
South school is the old campus and the headquarters. The accommodation environment can't be compared with the new campus, but the academic atmosphere here is very strong.
It depends on which campus you went to for the postgraduate entrance examination.
