In Sanben's science and technology campus, the dormitory building is relatively old (because there is nothing new), with eight people, a balcony and a small cabinet for each person. High-power electrical appliances are not allowed in the dormitory, but students always use them quietly. The computer can be brought, there is a telephone line under the bed, and you can connect the network cable. But some dormitories can't use that line, and air conditioning is necessary. There is only one electric fan, which is very hot in summer and I can't sleep. Shijiazhuang.
