In this work, Paul Klee pulled out a line from the fish, with the red arrows pointing to the cluster’s head to express brain boosting. In addition to a fish in the dish, other things were represented by the symbols, such as “the moon”, “the sun”, “plant”, “fish” and “figures”. Paul Klee was not only one of the earliest modern painters, but also a musician and a poet. The connotation of words, letters, numbers and symbols in his works was often alluded to the music and poetry. He was able to freely transfer between the concrete and the abstract, lines and colors, large and small, and watercolors and oil paintings. Sometimes Klee used the Fauvist colors, but he had removed the stinging jerky. The red and green with the soft sense made people reminiscent of the beautiful moonlight which itself was the dream of the sun dominating the dreamy world.
