Using 1.1.1.1 through a VPN in China

I’m in China. I regularly use two VPNs that are reasonably reliable though lately I’m having a problem accessing certain US sites either because my IP address or DNS is identified as being international.
If I switch my DNS to 1.1.1.1 which I used when I in the US will I be able to make the connections I want or will I be blocked on the China side even though I’m using a VPN to connect to a US Server?
