This masterpiece was composed in the autumn of 766 CE, the first year of the Dali era under Emperor Daizong, while Du Fu was residing in Kuizhou (present-day Fengjie, Chongqing). Although the An Lushan Rebellion had been quelled, separatist warlords remained powerful, Tibetan incursions continued, and the region of Shu itself was not free from disturbance. Living in White Emperor City, high atop the mountains at the entrance to the Qutang Gorge, the poet beheld both the perilous majesty of the river landscape shaped by nature and the desolate social spectacle of a people impoverished and subjected to relentless exploitation in the aftermath of war. The violence of the natural world and the cruelty of the human era resonated profoundly within him, transforming into this poem. Here, White Emperor City is not merely a geographical location but the commanding vantage point—the very eye of the storm—from which to observe that fractured age.
