I’ll start by saying this: as of October 2022, it is still possible to connect to a VPN in China. It’s been difficult to connect at times but yes, it is possible.
The question if VPNs work in China repeats on a cycle, a fact that you probably know well if you’ve lived in China for more than a year.
During important government meetings, major holidays or during sensitive anniversaries, it becomes harder to connect to VPNs.
…but sometimes very, very hard.
That’s why it’s important to choose a VPN that dedicates significant resources to serving the China market.
