《文心雕龙·章句》
分界语言，连接字词才能够分成各个单位，明确情境，概述所包含的思想并把它融入到既定的体裁里，即便章句二者的界限不同，它却能够像道路一般相互连接。
局言者，联字以分疆；明情者，总义以包体。区畛相异，而衢路交通矣。
Dividing language and connecting words can be divided into units, clarifying the context, summarizing the ideas contained in them and integrating them into established genres, even though the boundaries between chapters and sentences are different, they can be connected like roads.
