"Confusion" is a poem written by the German poet Hesse. The civilization created by humans has set restrictions for humans themselves, and nature is getting farther and farther away from us. The primitive and innocent world full of harmony in the past has become people's ideal sustenance. People have fallen into a desperate situation. In the dark night, only the call to return home is still heard from deep in the heart. A lonely and melancholy soul in modern civilization yearns for the lost "beautiful world" and finds his lost self in the dream of harmony with nature. This is the theme of "Confusion".
