you know, when i was in china, i was a teacher at one of the schools. and it came to my attention that i did not have the right kind of visa to be there because the company that sent me did not set me up with the right visa or something. but there were police in china that started to come by the school to check passports and stuff and i think they were checking to see if people had the right visas. well, when that happened, the teachers at the school told us we had to evacuate and hide. so we went out the back and hid from the police. then when the police were gone , we went back in side and went back to normal. anyway, after that happened. i got a plane ticket and did the "midnight run" out of china. i took a train in the middle of the night to hong kong. and then took the first flight out of hong kong i could get. so that i did not wind up in prison in china. i am not sure how serious it was but i decided i did not want to have to be an illegal worker in china.
anyway, you can do the midnight run.
