《文心雕龙·练字》
《尚书大传》中有 别风淮雨 的说法，《帝王世纪》则说 列风淫雨 。 别 与 列 、 淮 与 淫 ，就是文字相似而于不知不觉中改变的。 淫 和 列 的字义妥当但不奇特， 淮 、 别 二字于理不合却很新奇。
《尚书大传》有 别风淮雨 ，《帝王世纪》云 列风淫雨 。 别 、 列 、 淮 、 淫 ，字似潜移。 淫 、 列 义当而不奇， 淮 、 别 理乖而新异。
There is a saying in "Shangshu Dachuan" that "the wind is different from Huai rain", while "Emperor Century" says "the wind is lewd and rainy". The difference between "different" and "row" and "Huai" and "yin" is that the text is similar and changed imperceptibly. "Yin" and "Lie" have proper meanings but are not unique. The two words "Huai" and "Bie" are unreasonable but very novel.
