There are other countries that routinely block traffic like Iran or Russia, but there are also some simple methods that go right past the GFW many times, like VPN traffic that is tunneled through regular TLS, or even just plain SSH.

The "new hotness" is randomizing your TLS fingerprints and masquerading as legitimate web traffic/domains, as well as tunnel/proxy/VPN setups that utilize multiple endpoints at once to spread out the "suspicion" of all your traffic going through a single host all the time.
