This kind of scene should only exist in the sky, just like a fairyland falling into dust. What do you mean?

The scenery should only be in the sky, like a fairyland. This kind of scene should only exist in the sky. This poem was written by Wang Zhihuan, a poet in the Tang Dynasty. It expresses the mystery and sublime beauty of the sky, which is beyond human reach. Just like a fairyland, it means the scenery is beautiful, just like the place where immortals live.
