1. Three books and two books are together, but there is still a distance. Generally speaking, we seldom go to two books, usually in our own place (quite small).
I think the style of study is good. Although there are three books, the teacher is still very responsible.
There is a football field, but it is not very good. It's real grass, not that kind of fake grass There are many football players on the playground.
There are two bathrooms in the dormitory, which are separated by partitions. Both bathrooms can take a bath. There is no air conditioning in the dormitory, only two electric fans. If you want to install air conditioning, you should apply to the school. The hot water in the bathroom is not supplied 24 hours a day. I don't know the exact time. There is hot water in the bath at night.
