Guilin Book City, or Guilin Book Wholesale Market (next to Zhongshan Middle School in Jiefang Qiaotou). However, the book wholesale market in Guilin will go during the day and close around 6 pm. If the bookstore doesn't have the book you want, you can also discuss it with the boss and ask him to bring it back to you when he buys it next time. Just pay a deposit.
