I was told to put my power bank into the checked bags and came home to find a piece of crumbled paper stating that they opened my bag, took my power bank, and 5 "flammable objects" which were included my huge external computer storage with loads of my travel videos on it along with other stuff. This place is a complete scam, gave me a terrible image of China. Beware of the men in golf carts offering help. On my way to Tokyo a man in the cart who had the airport staff badge on him came up to me and asked if I'm flying to Tokyo he then said that they are boarding and told me to get in or else I will miss my flight. I believed him since our security check took so long it was close to our flight It was a 1 minute ride to the gate and during that ride he demanded $20 from me, I said I don't have that money and won't give it to him and he started screaming and making a scene. Terrible experience I will avoid Beijing airport at all cost in the future.
