@blingring @GalacticTurtle As someone who’s been to China (work-related) I’d say your worries are justified. I’d be wary of going back. Increasingly, there is the risk that they will have some sort of minor political spat ongoing with your country’s government and decide to grab a random national from your country on trumped-up spying charges to use as a negotiating lever. And that random might be you.
I was warned don’t take your own or work IT kit (even smart phones) into even their embassy, and take a burn phone with you.
Also, you will be approached by members of their security services trying to suss you out - if you’re there on business, you will be assigned a “minder”, there will be random strangers on trains trying to get you into conversation, the “work colleague” from the organisation you’re visiting trying to get you drunk (that failed hilariously because being white European, my alcohol tolerance was way higher), randoms trying to come into your hotel room as part of sex-blackmail sting (particularly used against male visitors, but I had a scary incident round this).
On the plus side, you will be totally safe walking the streets over there.
