Since China Southern moved to their new terminal 2 building, a couple of things has been changed about this guide.
After disembarking, look for the transfer signs (pink) then go to the transfer service desk after going through the health checks. A China Southern representative Will guide You.
Fill in the blue arrival cards that are available there. Hand over the passport and arrival card to a police/customs officer and wait in the waiting area.
After You get your passport back, go through customs with the sign TRANSIT. After getting your stamp, move through the bagage claim area and go landside. Look for gate 50! Their is a special hotel accomodation desk. You Will get a sticker with the hotel name, and a taxi/bus driver Will pick You up according to You sticker.
