Anhui University graduate students all live in Huiyuan. If they can't live, they will be assigned to live together in the undergraduate dormitory.

The postgraduate dormitory of Anhui University is equipped with air conditioning, balcony and private bathroom. There is a private bathroom with a shower, but there is only cold water without hot water, which means you have to pack a lot of things to take a bath in the bathhouse. Besides, bathhouses are not open every day. The boy opened it one day, but the girl opened it by mistake. They look at the sky every time they take a shower. If you are lazy today and don't want to take a bath, you have to wait two days before taking a bath. There is still a time limit for bathing.
