What is the oldest collection of Chinese poetry?

The oldest collection of Chinese poetry is generally considered to be the "Classic of Poetry" (诗经, Shījīng), also known as the "Book of Songs" or the "Book of Odes".

Here's why:

* Ancient Origin: It's believed to date back to the Western Zhou dynasty (1046-771 BCE), with some poems possibly even older.

* Official Collection: It was compiled and standardized as an official text during the Spring and Autumn period (771-476 BCE), becoming a crucial part of Confucian classics.

* Vastness and Diversity: It comprises over 300 poems, showcasing various styles and themes, from folk songs and love poems to political and ritualistic verses.

While there might have been other collections of poems before the "Classic of Poetry," this one is the oldest surviving and most influential one, establishing a foundation for the rich history of Chinese poetry.
