Every employer is supposed to establish the location of their FTs at all times. I routinely received reminders and requests for information before holidays, but a simple email that "going to Shanghai, staying in hotels" would suffice.

If your friend actually saw the police at the school, I would be surprised. The police's arrival, if it did actually occur, is testimony to the pressure that the Xian police are under to keep meticulous records now. Both Xian and Shaanxi police were notorious for their corrupt collusion with recruiters and were soundly spanked by Beijing during 2016.

I suspect our forum's recruiter apologist in residence is a resident of that smoggy dodgy region.
