《南齐书·列传·卷五十二》
文字的读音衹有五声的不同，但写出的语言文句却不一样。世间万物，同类的情状几乎相同，但各人笔下描绘的却是千差万别。
俱五声之音响，而出言异句；等万物之情状，而下笔殊形。
The pronunciation of words has only five different tones, but the written language and sentences are different. All things in the world, the situations of the same kind are almost the same, but the descriptions written by each person are very different.
