You can’t inspect encrypted packets, what China does is network traffic analysis - examining headers and figuring out patterns based on metadata. They don’t care much about what’s being transmitted if using a VPN alone is enough to land you in trouble.
Deep packet inspection is a thing, AFAIK people in China uses a software called v2ray to counter that.

i think US carriers do the same thing to counter unauthorized hotspotting so even using a VPN didnt help
