I received my Notebook Pro a few days ago and managed to get the Office activated in the original Chinese Windows by installing VPN software on it and setting it to a server in India. When I then selected this as the region during the Office activation, it was accepted and soon showed up in my Microsoft account. I just installed it on the English Windows, so I can confirm this works. The only hassle was navigating through the various Chinese menus, but Google Translate through the camera of my phone worked well. 🙂
