Are you talking about a VPN into china or a VPN out to the western internet? For the latter, I don't know if this still works but last time I visited China my Google Fi plan (which has a built in VPN https://support.google.com/fi/answer/9040000?hl=en https://support.google.com/fi/answer/9040000?hl=en ) actually worked with no further changes, so I was able to pretend I was on western internet over 4G the entire time I was in China. This was in early 2019. Which is lucky for me because the school VPN I was initially relying on stopped working halfway through the trip.
