This poem was likely composed between 740-741 CE, during the Kaiyuan era of Emperor Xuanzong, a time when Du Fu, in the prime of his life, was traveling through the Qi and Zhao regions, living with the untamed elegance of a youth in fine furs and spirited horses. Through an ode of extreme praise for a steed from Dayuan (the Ferghana Valley in Central Asia), the poem gives full expression to the young Du Fu's soaring ambition and fervent desire to achieve greatness and render service. It stands as a model of the vigorous style and romantic aspirations that characterize his early poetry.
