The creative background of The Book of Songs;
Joo Won?, the birthplace of the Zhou Dynasty, was suitable for agriculture. Poems such as Gong Liu and Mianmian Guaju in The Scholars all show that Zhou prospered the country with agriculture, and the development of agriculture promoted social progress. After the conquest, the Zhou clan became the master of the world, and the patriarchal clan system, land, slave private ownership and the rule of aristocratic lords became the social and political characteristics of this historical period.
Apart from the tyranny of Shang and Zhou Dynasties, the replacement of Shang and Zhou Dynasties by Western Zhou Dynasty was mainly related to its slavery economic system.
After the establishment of the Western Zhou Dynasty, in order to ease the sharp contradiction between production relations and productivity, and ease the class struggle, slavery was turned into serfdom, as Wang Guowei said in On the Shang Dynasty System: "The political and cultural changes in China were not drastic during the Yin and Zhou Dynasties ... On the surface, the three major changes during the Yin and Zhou Dynasties were nothing more than the rise and fall of a family and the transfer of the capital. Judging from the implication, the old system is abolished and the new system is promoted, and the old culture is abolished and the new culture is promoted ... "
Compared with Shang Dynasty, the Western Zhou Dynasty promoted the rapid development of social spiritual civilization due to the great changes in the economic system. As a representative of literature, the appearance of The Book of Songs is an inevitable product of the progress of the times, which in turn promotes the progress of social civilization.
