I was a bit confused about where to get the luggage at the airport, because I thought A13 was the baggage claim area, but that's not the case. You have to leave the baggage claim area and go to the door to see a small counter. When going to Hong Kong, you should definitely buy an octopus card because it is extremely convenient. You can swipe on trams, MRT, and buses, and you can even swipe at Seven Eleven. If I have any leftover money, I swipe it at the Burger King fried chicken restaurant outside the airport and give it all the money :))))
