When I was in China I would use my own VPN using ec2 and the now defunct Streisand (which uses stunnel). First few requests were always fast but as you use more bandwidth your requests would start to slow down considerably.
Oddly a foreign sim gets uncensored internet, so that's what I've recommended to travelers, but haven't been back since COVID so that might be outdated info.
