Beijing book wholesale market includes Wang Siying book market and Sweet Water Garden book market. I often go to the book market in Sweet Water Garden, 700 meters south of the south gate of Chaoyang Park. It's very big there, so go for a walk when you are free. I often buy books online, too. Anyway, I just look at my time. If I have time, I will go for a walk in Sweet Water Garden. I wanted to read that book when I was busy, so I bought it online. There are many websites that often buy books, such as Jiahu Book Network, Dangdang and JD.COM. My shopping philosophy is to go wherever it is cheap, but the quality must be guaranteed. I don't buy pirated books.
