The Book of Songs has three parts: style, elegance and ode. Among them, "wind" includes "the wind of fifteen countries", and "wind" means local wind and wind ballads. "Wind" includes folk songs in fifteen places, called "Fifteen Kingdoms Wind", with 16 articles, which is the core content of the Book of Songs. "Elegance" is elegant music, which is divided into "elegance" and "small [1] elegance". There are 15 poems, including 31 poems of elegance and 74 poems of elegance. "Ode" is a sacrificial music song, which is divided into "Zhou Song", "Lu Song" and "Shang Song", with 4 poems. It is one of the Five Classics. The Book of Songs has a history of 25 years. The Book of Songs has collected 35 poems, of which 6 poems are Sheng poems, with only titles and no content, and there are 35 existing poems (with both titles and words). In the Warring States period, the ceremony collapsed, a large number of music scores were lost, and the only remaining lyrics were compiled into the Book of Songs. The pre-Qin dynasty was called "Poetry", or it was called "Poetry 3" in whole numbers. In the Western Han Dynasty, it was honored as a Confucian classic, and it was originally called The Book of Songs, which has been used ever since. At the beginning, these poems were all lyrics of songs with music, retaining the combination of ancient poetry, music and dance, but in the long-term circulation, music and dance were lost, leaving only poems.
