The Chinese Internet block is surely not just about sex. Last evening, I went to a grocery store in Yangqiao, a countryside suburb of Wuxi. I saw Adult DVDs prominently for sale there. Surely, with its excess of young males, the Chinese government would want them to have an outlet for their loneliness.
There is a new expat for Wuxi Expats online: http://wuxiguide.net. It is sure to give Wuxi Life (aka Wuxi Death) a run for its money.
