It seems like regular people can get a public IPv6 so they can self host at home. Although, technically, everything public facing needs a ICP license so hosting stuff on Port 80/443 can draw a target on the head

Otherwise rent a vps in Singapore/Korea/Japan plus a .com domain and access via cloudflare tunnel as too much traffic over SSH/VPN/rarely used ports to a fresh Ipv4 address leads it to automatic probing and ban https://gfw.report/blog/gfw_shadowsocks/

This a rabbit hole that is probably political.

China is very aggressive with controlling the movement of information and they fear the general public. Somehow I don’t see them wanting people to start self hosting. They want people to submit to centralization so that they can be monitored for thoughcrime. Individual websites are harder to control which is not what China wants.
