Creation background of Qiupu Song:
Qiupu, a county in Chizhou County in the Tang Dynasty, was named after Qiupu Water, which was one of the producing areas of silver and copper in the Tang Dynasty. Li Bai visited Qiupu three times in his life, leaving more than 7 excellent works. These seventeen poems were written during the second visit to Qiupu in the thirteenth year of Tianbao.
At that time, Li Bai had been away from Chang 'an for ten years because of his neglect. In these ten years, Li Bai-yun traveled all over the world, being at home everywhere, going north to Yan and Zhao, and south to Jiang and Huai; Among them, there are many happy times, especially when I traveled with Du Fu hand in hand with Liang and Song, and talked about wine and poetry. However, he was not in a good mood when he was in Qiupu.
In the twelfth year of Tianbao, he visited the thistle in the north, and witnessed An Lushan's powerful forces and the monarch's cultivation. At this time, he traveled to Jiangnan again with great grief and indignation.
