Yeah, one other thing that works is to use a foreign wireless connection (of course it is carried by ChinaTelecom etc) like AT&T or BT. I've rarely seen those connections blocked, even when hotel/local wired connections and the company VPN were all... "slowing down" for certain sites. I haven't been to Hainan though so I don't know about any particular issues there.

It works because the local telco is actually relaying the data frames back to the home telco (beyond the firewall) instead of terminating the data session themselves within the firewall.
