There are too many needs in life that require us to give up, take a step back peacefully, look at the vast sea and sky, and the sky is high and the clouds are light; listen to the wise man fishing by the autumn water and laughing, "You are not me, how do you know that I don't know the joy of fish"; listen to the poet who "picked chrysanthemums under the eastern fence and saw the southern mountains leisurely" talk about "not being eager for wealth and honor, not being sad about poverty and humbleness"; listen to the gentleman with plum wife and crane son sing "sparse shadows slanting across the shallow water, and the faint fragrance floating in the moonlight at dusk"... They withdrew from officialdom, gave up the world that should not belong to them, but walked into the paradise that belonged only to them. As the famous poet Guo Xiaochuan said: "If you can be a pillar to support the sky, be a pillar to support the sky; if you can be an oar, be an oar to row a boat."
