I’m in Shanghai a few times a year on business and really have to double check that I have multiple VPN options available before leaving. Had a coworker have his phone checked at customs but we always bring dedicated “China-only” cell phones and laptops. They seem to be getting more on top of crushing outside communications but I always get at least one connection working when there. Last time it was an ssh tunnel to an AWS instance that I used to route traffic. Before that it was ExpressVPN which gave me trouble on the last visit. China is playing whack a mile with the VPNs.
