FYI.
Chinese have ban all service from google.
this web page contain some links from google, like
fonts.googleapis.com
maps.googleapis.com
ajax.googleapis.com
so people from China can not view this page without any proxy.
my solutions is add these to my host file, redirection all google service to localhost.
127.0.0.1 fonts.googleapis.com
127.0.0.1 maps.googleapis.com
127.0.0.1 ajax.googleapis.com
