For second-hand books, there is one below the Second Institute of Education, on the first floor of apartment 14, diagonally opposite the Hundred Yuan Restaurant. However, there are many stalls selling second-hand books in Taohai and Ximen at the beginning of each year, so you can go and have a look. If you want to buy new books, you can go to the gate of a teaching center near the library. In addition, the school also sells books, which are more expensive, behind the library, but there are many books in the library. I suggest you look for it in the library now. If not, you can go to the bookstore and buy it online. If it is not urgent, it is more cost-effective. Dangdang is good, and Taobao also has it. I suggest you buy it online. Express delivery is fast!
