One pool of clear water and one pool of lotus.

There is a silver pond on one side and the sky on the other. A pool of clear water, a pool of lotus flowers, a pool of silver and a piece of sky means that lotus flowers grow in mud, but they can lead an honest and clean life and maintain lofty moral integrity. The same is true of being a man. It is more respectable to stick to the true colors, which comes from Zhou Dunyi's "Love Lotus Theory" in the Song Dynasty.
