hello i will go from australia to delhi(india) via gaungzhou.how i will take my second flight?

Well, your flight will arrive at the arrival hall on the first floor in the building. If your luggage is checked-in through, you have no need to recheck-in it. You just need to go through the transfer area and get your next boarding pass. Then walk to the East 1 Concourse of Area A to wait for your flight.
