| The writer of the preface of the <Book of Songs> is who has always been a historic affair, as its writing era too. In the debate, some scholars propose the preface of the <Book of Songs> is divided into two parts, the early preface and the finished preface, and the two parts were not a person worked. This view has been recognized by today's most poetics, in the study, the main ideas of the poem also to be discussed, but overall involves rarely. If combined with textual content from the microcosmic study about the relationship between these two parts, it will be to provide valuable clues about the poem's authors and writing era. After comprehensive investigation of the 305 poems, this article selects and analyzes several typical poems to comb relationships between the early preface and the finished preface .There are two types of relationships. One, the two parts are basically the same but nuances, there are three pomes to specific analysis, as follows:<Bei feng ?Bai zhou> <Wei feng ?Fa tan> <Yong feng ?Xiang shu>.The other, the two parts are opposing and conflicting, the selected three poems as follows:<Bin feng? Fa ke> <Yong Feng ?Zai chi> <Wang feng ?Da che>.Besides, the directories of the same type pomes are listed in the rear.Through the specific analysis, the author concluded that the preface of the <Book of Songs> was the teaching outline of the <Book of Songs>. It was finished after the previous scholars organized the related material. Because the early preface and the finished preface are opposing and conflicting, they are not written by a single person. The two parts agree because the writer referred to the pre-Qin period related material or scholars'commentator material during the previous dynasties. The two parts are opposing and conflicting because the writer of the finished preface misconstrued intent or drew a farfetched analogy. This happened because the writer worked the finished preface so late that can not hold the point of the <Book of Songs> or the early preface, or because he pressured by political indoctrination had to do so. The early preface has finished a little early, maybe in the pre-Qin period, maybe during the early Han period, and it was not later than the early Han period, its praise and sarcastic comments seems that it was the posterity attached. The finished preface was the commentator tributes of the scholars who lived after the early Han period, and it has the pre-Han period origin, but it has many farfetched analogy, some are hard to understand, the other are easy, it seems that the whole finished preface was not written by only one person. Although the early preface is all not meet the Book of Songs, it is not far away from the creation era, so it should be respected. Although the finished preface should not be all abolished, we could choose good parts to use when to explain the poem. |
