A response I got from the local LUG here in Hong Kong to a post about translating the wiki articles into Chinese pointed me to the links below:

http://www.centoschina.com/ http://apt.nc.hcc.edu.tw/web/student_server_centos/student_server_centos.htm...

Posted just in case the Centos team has an issue with the first link. The site has a logo with 'CentOS' in it.
