Earlier quoted context omitted.
You're proposing a technical solution to a political problem. It doesn't work, this should be fixed at the source.
How exactly it doesn't work? Not even China has been able to make their Great Firewall resilient to stuff like VPNs.
I don't have any inside information, but my uninformed guess is that this is by design or at least tolerated to some extent. You don't want a watertight VPN because it stifles commerce.
China PR could pull a Singapore and impose the kind of punishment for using VPN that Singapore does for hard drugs. I have a friend from Texas who lives in China PR and regularly uploads to YouTube. Nothing political, he is talking about living and working as a teacher, so he isn't doing anything controversial but in theory what he is doing is unlawful by China PR laws, right?
