This happens regardless though. When it is known that someone is going back to the States, the poor sap going (that poor sap being me) is often given a long wish list of treasured items to haul back to the PRC. I really like to travel light, a form worked to perfection back when I traveled a lot on business for Apple, so lugging a 75 pound suitcase is a bit of a chore for me. Don't get me started on the $50 fee for being over the luggage weight limit.
At least this time I didn't have to smuggle anything rectally. That can really make an 11 hour flight seem longer than usual.
