According to the inquiry of Xiaoxiao Knowledge Station, "I heard that Wang Changling moved to Longbiao Kiln to send this news". At that time, Wang Changling was demoted from Jiangningcheng to Longbiao County (now Qianyang County, Hunan Province), and Li Bai wrote this poem in Yangzhou to express his anger and comfort.
Poem excerpt: Huayang falls full, Wendaolong crosses five streams. I entrust my sad thoughts to the moon, hoping to accompany you to the west of Yelang.
