When was the earliest poem about bamboo written in ancient times?

The Book of Songs is my country's first comprehensive collection of poems. It contains a large number of bamboo poems, with 5 directly mentioned and appearing 7 times, and dozens of indirectly mentioned. For example, "Poetry of Wei Fengqiao" says: "Looking at Qiao, the green bamboo is Yiyi." Historically, there have been different views on the above-mentioned records about bamboo in the Book of Songs, but in fact it is conclusive that it refers to bamboo. The Book of Songs was compiled in the Spring and Autumn Period. Since then, bamboo poems and paintings have been recorded in various classics of various dynasties.
