Huge airport, overpriced cafe, useless wifi unless you have Wechat and VPN accounts
(without VPN, you can't access Whatsapp, Viber, Google etc.). But the staff were helpful when I asked for directions. Beware of those ones driving golf carts to help you catch flight because they would ask for money even though it says "free" on the carts. I didn't have change so I had to run, luckily I didn't miss my flight. As for power bank, the customs didn't take it away even though it is heavy and big.
