I ordered it in advance on the internet, but unfortunately it rained that day, so I couldn't see the blue sky, white clouds and more beautiful scenery. It was planned to come at 4 p.m. and see the sunset after the city view. The hanging experience requires extra tickets. It will give you a buzzer, and it will ring as soon as you arrive. I waited about 40 minutes. In the experience platform, you need to temporarily save your personal bag, because the first time you go, you don't understand it, even your mobile phone has been saved, so you can't take self-portraits in it, or let others take pictures. Only automatic cameras can take pictures, and extra money is spent to buy pictures. Group of 10 people, about 10-15 minutes for each group
