There is a Xinhua Bookstore in Xiaozhuang next to the Second Hospital in Chaoyang District. Just take Jingguang bus 1 12 and get off at Xiaozhuang Station. Just cross the street. When you get off the bus, you will see a McDonald's, which is next to Chaoyang Cultural Center. There is a library in it, including a study room, a reading room, a lending room and magazines. But if you want to borrow books, you must first get a library card, which can be divided into 10 yuan, 25 yuan and 50 yuan. You can borrow one book, three books and five books at a time. Sweet water has a book wholesale market, but I'm not sure how to get from Beijing-Guangzhou.
