I was in Shanghai for a month earlier this year and half my usual VPNs failed after a few days. What really helped me was checking out some best VPN for Windows in China before the trip. Some of them surprisingly held up well for messaging and quick browsing, though I still kept a paid backup just in case. I’d say download a couple before you land — they block most VPN sites there.

Ok this is interesting. Cause i don't always like to use some vpn, but sometimes i just recquire them

But not every vpn is good. So one need to figure out how to choose proper one
