The Book of Songs is my country's first comprehensive collection of poems. It contains 305 poems from the early Western Zhou Dynasty to the middle of the Spring and Autumn Period, about 500 years ago. The Book of Songs is divided into three parts: Feng (160 chapters), Ya (105 chapters), and Song (40 chapters). They all get their names from music. The meaning of "wind" is tone. The ancients called "Qin Feng", "Wei Feng" and "Zheng Feng", just like now we say Shaanxi Diao, Shanxi Diao, Henan Diao, "Ya" means Zheng. People in the Zhou Dynasty called Zhengsheng Yale, just like people in the Qing Dynasty called Kunqiang Yabu, which has a sense of respect. Daya and Xiaoya may be divided according to the chronological order. "Song" is a song used in ancestral temple ceremonies.
