I left China a few months ago after cancelling my WP, but my residence permit is still valid for the next six months (stamped). My ex employer wanted to cancel the residence permit as well, but I was in hurry to leave China, so we didn't do anything about it.
Now, I'm not sure what would be the validity of my RP since I've left mainland China. Can I fly in and out showing the same RP at Chinese immigration? Will I be flagged at the airport and get in trouble doing so?
