《易》作为姬周族所特有的卜筮类文献,在春秋时期仅在北方黄河流域流传,而未达南方长江流域。与此相反,《书》《诗》等义理类文献则多见于南方楚人的征引活动中。这反映出春秋时期以《书》《诗》为代表的义理类文献与以《易》为代表的卜筮技术类文献具有各自的流传特点,这一流传特点对后世的文献分类格局产生了重要影响。 As a special type of literature of the Ji Zhou ethnic group, Yi mainly circulated in the northern Yellow River basin during the Spring and Autumn Period and did not reach the Yangtze River valley in the south. On the contrary, “Li” and “Shi” and other literary texts are more common in the activities of the Southern Chu. This reflects that the literature of the classifications represented by “Shu” and “Shi” in the Spring and Autumn Period and the literature of the classifications represented by “Yi” have their own characteristics of spread, which has an important influence on the classification of documents in the later ages .
