As a Chinese user who regularly breaches the GFW, QUIC is a god send. Tunneling traffic over a QUIC instead of TLS to breach the GFW has much lower latency and higher throughput (if you change the congestion control). In addition, for those foreign websites not blocked by GFW, the latency difference between QUIC and TCP based protocol is also visible to the naked eye, as the RTT from China to the rest of the world is often high.

I want to visit China but am afraid I will not be able to breach the GFW (as other friends have not been able to).

Any resources you can point me to to help me be more successful?
