The "City in the Sky" in Shenzhen is like a cruise ship sailing in the air. The verdant lawn sets off the "City in the Sky", transporting you to a summer scene straight out of a Hayao Miyazaki film in an instant. Inside, there is a cloud - above library and a coffee shop. Order a cup of coffee, and you can read books while enjoying the view of clouds or the sea. Look up, and you'll see the blue sky and white clouds; look down, and you can overlook the mountain - sea city.
