Currently in China (as a visitor). Wireguard literally just works (to a VPS). Mullvad works as a commercial provider, just slower. Xray-core (vless, Trojan) if you're paranoid. I have my own proxy over syncthing relays https://github.com/acheong08/syndicate which I use to proxy to my home in the UK (residential IP) without exposing any ports.
I get rate limited to around 10mbps in Chongqing. Was slightly higher in Beijing.
