That's the exact reason why Communist China setup the firewall in the first place. Good luck.

The two are vastly different.

The GFW doesn't just block websites/networks/content that is controlled by adversarial foreign governments, but all websites/networks/content which the CCP is unable to censor. The GFW is about controlling the flow of information to its citizens from __any__ party not under the CCP's control.
