Did all countries have poetry in the pre-Qin period?

The poetry written before the Qin Dynasty unified all countries is called Pre-Qin poetry. Pre-Qin poetry includes the Book of Songs, Songs of Chu, some Han folk songs from the Spring and Autumn Period and the Warring States Period, and some primitive social ballads. Folk songs and ancient ballads are collected in "The Source of Ancient Poetry". Pre-Qin poetry is the source of Chinese Han poetry, among which "The Book of Songs" is the source of Chinese realist poetry, and "Chu Ci" is the source of Chinese romantic poetry.
