You can go to Xinhua Bookstore in the city. You can take bus No.3, No.5 and 10 to get there. The relatively concentrated book market is in the north of the Yellow River market, almost at the central station. This book market includes many bookstores in Salt Lake District, which are basically complete. You go to grand central station by bus. Get on the bus and make it clear to the conductor, and he will remind you to get off. It took a long time to find it, and it came to an end in an alley. There are advertisements for several bookstores in the alley, which seem to indicate that they are book buying centers.
