朱熹有《观书有感二首》,其中第一首是这样写的:半亩方塘一鉴开,天光云影共徘徊。问渠那得清如许?为有源头活水来。方塘半亩虽然不大,但它却像一面明镜,淳澈明净,一尘不染,天光云影在其中浮动闪烁,淳澈明净的方塘之水与天光云影交相辉映。方塘如镜面般明净,这是静。然天光云影 Zhu Xi has “Two Senses of Books”, the first of which is written in this way: A half-acre square pond is opened, and the clouds of light are heard. Ask the canal to be so clear? The half-acre of Fangtang is not large, but it is like a mirror, clear and clean, spotless, clouds of light in the sky floating in the blinking, clear and clean water of Fangtang and sky clouds shadow each other. Fangtang is as clear as a mirror. This is quiet. Natural cloud shadow
