Every classroom has air conditioning (except for a few classrooms whose air conditioning is broken), and there will be two in the big classroom. However, the air conditioner will only be turned on with a key when it is very hot in summer. At night, the classroom will also be air-conditioned when attending the state religion and studying at night.
Freshmen and sophomores only have a few specialized courses in university, most of which are in Wei Yi Building, and there is no air conditioning.
