Google cooperator Tianya opens an Answer service at wenda.tianya.cn. But according to the server IP, it is running on Google China’s servers. Tianya is one of the biggest online communities in China. Most users of Tianya are clerisy and patriot, accord with Google China user features.

Why on Google server? May be the reason is providing online community service need a government license. But the license only opens to Chinese corporation. So google has to publish it as one cooperator’s service.

Almost every search provider in China has its answer service. The leading one is Baidu Zhidao. Alexa.com shows Zhidao is the 6th service in Baidu, offers 5% traffic for Baidu.com, and now there are 20 million answered questions on Baidu Zhidao.
