Here's one I've noticed in the past month or so since being back in Beijing: at the East Gate of the Workers' Gymnasium (the round one), in the afternoon all the FedEx delivery vans gather around and start passing packages back and forth--sort of a Chinese FedEx Fire Drill. Sometimes there will be 8-10 of them doing this tailgate maneuver. I don't get it...isn't this sorting done at the FedEx warehouse?
