It's important to note that this will not easily benefit the people of China. China has its own edition of Minecraft which is not compatible with servers running the mainstream edition.
I think the only reason the Chinese edition exists is because most Chinese people aren't bothered by censorship. the main reason they might want to tunnel outside the Great Firewall is if they are bothered by censorship. any Chinese person who can read English and use a VPN is "free" to download and use the official Minecraft. but doing so labels them an activist, spy, traitor, etc. it's like trying to play games on a school computer, if there's a will there's a way. I appreciate the effort but if you want to learn anonymously, it would be much easier to use Tor and Wikipedia
