It expresses the meaning of history passing by in a hurry.

When you hear the music "Floating Light", a kind of history will flash through your mind, like a fleeting light, passing by in a hurry, you can't catch it, you can't stop, and no one can stop it from moving forward. The feeling of running feet.

"Floating Light" is a purely musical song. Although it has no lyrics, it seems to be telling its own story. It once appeared in the popular drama "The Age of Awakening".
