Google map China url

Hello，

Our server is in China for local service, unfortunately, any global resource like google, twitter, Facebook…are blocked by China government Firewall name Great Firewall.

Fornately, we can access google map at https://www.google.cn/maps, but we can not access maps.google.com.

So, it would much great if you would like to help me with a short code snippet to switch the url, So that I can use the plugin of Code Snippets to input that code.

Thanks in advance, and have a nice day

Alex
