Shentong is in the North Gate 2, Tong Yuan is in the new library, Dayun is in the old library, but it has moved to the new canteen. Zhongtong is in the digital family on the first floor of Xiangzhangyuan, and there is also a bookstore in Xue Hai. I don't remember the specific express delivery. There seems to be one in front of the new gymnasium. I have taken the express delivery in these places.
