Baoding New Century Book Center is located in the north of Baoshi Primary School, Yonghua Street (south of the intersection of commercial buildings). It's quite cheap. As a student, I often go there to buy books, which is about 30% cheaper than the underground bookstore. Ask!

Also, you can go to the teacher who bought books on a tricycle in Yuhua Road and ask him where he got them. The price given by the bookseller of this tricycle is much cheaper than that in the bookstore.
