The lady at the enquiry desk at T2 told me there is no ATM in the whole Airport.

Then she went with me, mind you for more than one hour, through the line 3/10, Exit 7 Underground Labyrinth (she even struggled with the help of her navigation-app) and we visited several bank branches together.

None of them, including the Bank of China branch, accepts VISA/Mastercard or foreign cards in general.

But I have Alipay/Wechat if necessary.
