Can I change from China version to other country version?

All Android phones in China comes without Google Play or any Google services.
It seems the only option is to root and install the google apps, but I was wondering what happens if I change the stock firmware from China to another country (let's say Hong Kong for example) in order to download play store. Any help would be helpful thanks!
