I would find it hard to believe if someone tried to tell me that there was not such a website, and that people in China relied on gobase. Isn't there a Chinese-language resource for SGF files?
Recent games, download SGF or view online with a java applet.
This one is a little gold mine if you know how to parse the page, old Chinese games, recent games...etc (downloadable SGF)
They have an english version. The kifu search is at the bottom of the page. (they also have tsumego, fuseki, joseki...etc.)
Here you can find a list of the players in their database.
On this page you can find recent professional games and games played on sina's weiqi server.
The Chinese portal for Tygem also has some Tygem + pro tournament kifu. (need to install an addon for IE to view)
