Am I able to play WOA in China? Because I’m going there for a week and I’m going to miss playing it. Has anyone got any thoughts?
Nope. AFAIK WoA uses Google Cloud, which as we all know is banned by the Great Firewall 
You’ll need a VPN.
In short, YES, but…
I’ve been to China last year and get a really working VPN there, many VPNs cannot work there properly or work only under very specific network environment.(this indicates different ISPs, regions in the country).
With a VPN the game is going to work for sure.
