The largest and most complete bookstore in Harbin is Xuefu Bookstore. There are many types. 10% off all the year round, it seems to be 8.5% off recently. I usually go there to buy books anyway.

Take 107 from the entrance of the railway station and get off at "Heida" station.

Huihai Book Building is newly opened, and the discount is also quite hard. It is located in the electric meter factory. You also take the bus 107.

Xinhua Bookstore is a national chain, so there is no need to introduce it. Take 103 at the entrance of the railway station, get off at Nangang Jianshe Street and walk to Yuanda Mall, which is next to it. Just ask. It is easy to find.

As for book wholesale, you must go to Antarctic Book City. It is a collection of books and periodicals in Harbin. There are more magazines and textbooks. Discount depends on your bargaining power.

After arriving in Harbin, there is a telephone number asking for directions above every bus stop sign. Where are you going? I don't know what bus to take. Just call which number. Charge by local phone.

Good luck!
