What is China's earliest collection of poems?

The Book of Songs is the earliest collection of poems in China. The Book of Songs was originally named "Poetry", and there were 305 * * * poems (in addition, there were 6 poems with titles and no content, which was called "Sheng Poetry"), so it was also called "Poetry 300". Confucianism has regarded it as a classic since the Han Dynasty, so it is called The Book of Songs. 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.
