Per Hebei Province Traffic Police, starting July 20, all 26 Highway check points surrounding Beijing will check all passengers’ ID. Every passenger is required to scan his/her ID card on a card reader. Even if one passenger fails to show a valid ID, everyone on the vehicle, including car, truck and bus, will be denied passage.
