During day time the airport is nice but it's absolutely worst if you're staying overnight. Not enough chairs to sit or sleep on, no stores open to buy food, you can only buy drinks from a single vending machine that only accepts chinese yuan.

ATM machine is on the 2nd floor and is off limits at night unless you ask one of the staffs to accompany you with their elevator key.

For first timers, you won't be able to connect to the wifi unless if you have a chinese cellphone carrier. If you are connecting a flight to another country at night they will unload all your luggage, check in and carry on luggages.
