This would be an interesting test, although I don't think even a VPN exit node in China is good enough unless your device also feeds bogus GPS coords that show you are in China. I used to do with the Xposed all the time (because apps have no business knowing where I am) but now that Android is so hostile toward root and power users, I don't know how doable it is anymore (though I'd love to hear if someone does).
