We have deployed a site in US, and it is working fine. But i'm unable to open my site in china because of great firewall of china
How we can access the site in China
I think the best way to create sub-website for another country is matching the stylistic and literary attributes of local. So that the website will work well without interruption.
Another way is to buildup a forward proxy server in the region that country can accessed. Then the proxy server redirect all the requests to you site. But this way is easy caught, and then the proxy server will be blocked by the Country Firewall. Here you may setup an encrypted tunnel between the proxy server and your site.
