The Book of Songs is the earliest collection of poems in the history of China. The Book of Songs was originally named "Poetry", and there were 305 * * * poems (in addition, there were 6 poems with no content, that is, no words, which were called Sheng Six. What has no content is Nan Chang, Bai Hua, Shu Hua, You Kang, Chong Wu and You Yi), so it is also called "Poetry 300" and "Articles 300". Confucianism has regarded it as a classic since the Han Dynasty, so it is called The Book of Songs. (The official use of The Book of Songs should begin in the early years of the Southern Song Dynasty-Qu Wanli). Mao Heng in Han Dynasty annotated The Book of Songs, so it was also called Mao Shi. Most of the authors of the poems in The Book of Songs cannot be verified. The area involved is mainly the Yellow River Basin, starting from Shanxi and eastern Gansu in the west, southwest Hebei Province in the north, Shandong in the east and Jianghan Basin in the south. It collected 305 poems from the early Western Zhou Dynasty to the mid-Spring and Autumn Period for about 500 years, among which 6 poems only had titles. It was honored as a Confucian classic in the Western Han Dynasty, and it was one of the "Five Classics" respected by Confucianism. Originally called The Book of Songs, it has been used ever since. Music is divided into three parts: wind, elegance and ode. Among them, Wind is a local folk song with 15 national styles and 160 songs. "Elegance" is mainly court music songs, divided into elegance and vulgarity, 105; Ode is mainly ancestral temple music songs, with 40 songs. The main methods of expression are fu, bi and xing. "Fu" means paving the way, "Bi" means figuratively, and "Xing" means saying something else first to cause the words to be sung. Folk songs have the highest ideological value and artistic value in The Book of Songs. "Hungry people sing about their food, and laborers sing about their affairs." Vatan, Storytelling and Mang are Feng's representative works. The Book of Songs has a far-reaching influence on the development of poetry in later generations, and has become the source of the realistic tradition of China's classical literature.
