Liu Yuxi said in the preface to Seventy Rhymes of Liyang: "In August of the fourth year of Changqing, Yu changed from Kuizhou secretariat to Liyang (Hezhou), floating in Minjiang River, watching Dongting, passing through Xiakou, and going to Xunyang to the east." Liu Yuxi was banished to the south and went to Dongting in 2 years. According to the literature, there are about six times. Among them, only the transfer to the state, this time, is in the autumn. And this poem is a vivid record of this journey.
