Abstract: The short-chapter texts of the Spring and Autumn history widely circulated in the Warring States society constitute the direct source of the chronicle Zuozhuan.The examples of unearthed documents prove that the “initial Zuozhuan” before the chronicle Zuozhuan can be understood as the “Shiyu” texts of the Spring and Autumn history in the form of scattered compilation.The appellation and connotation of the “Shiyu” originate from the historical context of the Warring States period and the Qin and Han society rather than the general appellation in the contemporary academic circle.When the editors of Zuozhuan chose and processed the texts of the Spring and Autumn history,in addition to “split texts ” and “integrated texts ”,there are also linked texts and modified texts,so that it is in sequence and systematic,and thus can show its own value judgment.At the same time,the completion of Zuozhuan is also a process in which the writing subject of the Spring and Autumn history is transferred from the historians to the Confucian scholars through various schools of thought.

Key words: unearthed documents, Zuozhuan, the Spring and Autumn history, Shiyu, completion
