I Am Free and Happy

Knights and knights travel in rivers and lakes, duckweeds follow the flowing water, where can I find peace at the end of the world? The world is in chaos, but I am the only one who is calm, so how can others laugh! I follow what others say, I make my own arrangements when others are in chaos, and duckweeds take root. The world is so vast, it has its own place of freedom, and I am proud of it.
