I find that hard to believe. The last few times I've been to China (in 2019), none of the hotels I stayed in (all of them in Shanghai) had ipv6 for their guest WiFi.
I think it's a problem with the legacy infrastructure of WiFi hotspots in the hotels instead. And the final steps of the deployment were in October 2019, I think. Most mobile applications, China Mobile and China Telecom, both landline and mobile connections - everything works with IPv6 now. Even big corporate networks started to do the switch.
It's widely deployed in China - in households, Web and mobile services and applications.

Over 1/3rd of Google's US traffic is IPv6, so it's not exactly rare.
IIRC IPv6 became a ratified internet standard in 2017
