The most popular online bookstores in China are Kongfz.com, Dangdang.com, Amazon China (亚马逊中国 z.cn, 一站放心购全球) and Taobao. Of course, on Amazon and Taobao you can purchase far more than just books but if you’re looking for books there are millions of them on all these sites. All these websites have both English and Chinese paperbacks for sale.
For English paperbacks of contemporary readings and modern books, Amazon China would have the most variety. The best part about Amazon China is that you can search and browse in English unlike the other websites.
Our favorite online bookstore in China however is Kongfz. Kongfz (kongfz.com)【孔夫子旧书网】网上买书：图书_书籍_古籍_二手书，网上卖书：网上书店_古旧书拍卖，中国领先的古旧书交易平台 is a wonderful (although not necessarily as well known as Taobao or Dangdang) mega online bookstore which specializes in B-to-C and C-to-C selling of old and sometimes even ancient historical vintage books, ancient texts to photocopied reprints, manuscripts, magazines, newspapers, letters, calligraphy, scrolls, DVDs and other collectors' items that would be of interest to historians, hobbyists, academics intellectuals and simply interested in language, history and culture.
Many of these vintage books and other items are only available in single or very low quantities and hence when you see something you wish to buy on Kongfz, it is important to do so as soon as possible as it can very quickly go out of stock. Kongfz's constantly growing database renders easily searchable the holdings of literally thousands of bookshops in all corners of China. While Dangdang may be better for buying modern books, there is no doubt that Kongfz is the go-to-place for buying vintage books and items from China.
Hence which Chinese online bookstore you buy from will depend on your specific needs.
