2. The original Shadowsocks (SS) is still maintained. Some users are reporting that the GFW can now detect and block SS servers that do not use some form of obfuscation. One interesting innovation is the Cloak plugin for Shadowsocks-Libev. This aims to disguise the SS server as an HTTPS server.
3. V2Ray offers more features and is less likely to be blocked than SS, though it is harder to configure. The graphical user interface (GUI) for V2Ray is provided by separate projects such as V2RayN for Windows and BifrostV for Android.
4. The trojan-gfw/trojan project on Github has been in development since October 2017. It claims to imitate HTTPS so well as to be undetectable. Configuration is slightly more complex than SS/SSR. https://github.com/trojan-gfw/trojan
5. The ValdikSS/GoodbyeDPI project on Github claims to be able to bypass deep packet inspection (DPI). https://github.com/ValdikSS/GoodbyeDPI
6. A few netizens use Tor with the meek-azure pluggable transport, though the Tor Browser is itself difficult to obtain in China. MY PROTIP: USE SNOWFLAKE instead of meek azure
7.Wireguard may still work, though its protocol could conceivably be detected and blocked by the GFW at some later date. NOW IS BANNED

#1 - It's illegal and they tend to be somewhat serious about that.
#2 - Any major/reputable provider is going to be blocked.
#3 - Any unknown provider can't be trusted.
#4 - A lot of the VPN's they allow to work are because they're tap'ing the traffic anyways.
