Note: I'm not sure this works in China. We run a Tor node (non-exit). I forget if the IP address it is assigned to is the same as the Tor node. We have never had a Chinese customer. We have had customers from other countries in the region.
If you would like to help us fix it send us an email or contact me. I'll see what I can do.
