I have seen all the dorms, and they are all very good ~
As for bedding, quilts, towels, quilts, pillows, summer sleeping mats and mosquito nets, all should be prepared. You can bring it from home or buy it in Zhang Xiao's supermarket, but I heard from my senior that the quality is not very good.
Every dormitory has air conditioning, and the switch is not limited. The electricity fee is shared equally by my roommates. I asked my brother there myself.
