Where can I buy a crash book on architecture in Nanchang?

It is cheaper to buy genuine new books in the bookstore on Hongdu Avenue (about 30% off) or Xinhua Bookstore (currently in the old exhibition hall and the old Fushan family). You can buy used books and go to the South Library Road next to the provincial library (the one from the east gate of Normal University), where there are many related used books, with a discount of about 30%.
