What is China's earliest poem?

The knowledge we get from textbooks is that The Book of Songs is the earliest collection of poems in China, so many people think that the earliest poem should be the first one in the collection. In fact, there is an earlier written record of poetry. This poem is a two-word poem with only eight short words. This poem is called "Playing Songs", which is an ancient ballad in ancient times. This poem is recorded in the Spring and Autumn Annals of Wu Yue, and also included in the Ancient Poetry Source of Qing Dynasty scholars. The whole poem is as follows: broken bamboo, continued bamboo; Fly to the earth and leave. This word "Mao" is the word "meat" in ancient Chinese characters. The annotation I saw in the 234-word Poems of Past Dynasties 100 inscribed by Mr. Zhou is that the original intention of this poem is: to break bamboo, that is, to break bamboo, and to continue bamboo is to connect bamboo with skin or rope to make bows and fly soil, that is, to knead the soil into small pills and hunt meat, that is, to make slingshots.
