This seems like it's probably unhelpful and out-of-date. Any such how-to guide really should cover some kind of obfuscation to avoid the anti-VPN blocks. For instance, apparently the great firewall will let SSH terminal traffic through, but it uses heuristics to detect and block SSH tunneling.
This guide, is really more like "step 0" of a multi step process. All it does in orient a novice toward the services he will need to expend effort to try to access.
