How bad is the accommodation in Shantou University?

Shantou University has several dormitory areas. ABCDEF doesn't have a separate bathroom and balcony, so it's not well ventilated but it's not stuffy. Because of its annular structure, the ventilation of the inner ring is not very good. In summer, the roof and the inner ring are hot, but I don't feel very hot in the outer ring. Other dormitory areas have separate bathrooms. The balcony is better ventilated. If there is not enough on the roof, it will be hot because there is no air conditioning.
