For the most part, the Changchun Friends website is not very active and has been superseded by the Tencent "Wechat" app by the local expat community. This website is maintained sporadically, people may still join and membership is still open, but if you are a spammer, stay away. The archived information here is still useful, but some may be out of date. There are plans to make it more useful for static information in the future. If anyone needs information about Changchun or China, you may post a message and it probably will get a response but not immediately.
This is probably a well known fact. But I just stumbled upon the bookstore on Tongzhi Jie between Huimin Lu and Huimin Hutong, and found a lot of paperback classics in English - 20 rmb a piece. Some of them were second hand, but most of them are new. I got myself a bunch and thought I would spread the word.
Good day to you!
