Landlord, it seems that there is no book wholesale market you mentioned. I only know that books are generally in bookstores, such as Xinhua Bookstore at the intersection of Jiefang Road and Yimeng Road, Yimeng Culture Building at the intersection of Yimeng Road and Jinyi Road, and so on. As for the book wholesale market you mentioned, you can go to the cultural and sports wholesale market, which is in the north of Linyi International Trade Building and near the leather bag wholesale market.
