"Spring Hope" was written in 757. Two years after the An Shi Rebellion, Tang Suzong arrived in Germany. At that time, Chang 'an was burned and looted by Anshi rebels, and it was desolate everywhere. Du Fu saw that the mountains and rivers were still broken and ruined, but the land was desolate in spring. At this time of homesickness in adversity, he couldn't help feeling deep sorrow and emotion.
