These two poems are from Miscellaneous Songs written by Shen Quanqi, a poet in the Tang Dynasty. This poem is one of Shen Quanqi's representative works in Wuhou and Zhongzong periods, which fully embodies his Jiangnan complex. In the poet's mind, the beauty and tranquility in the south of the Yangtze River are what he has been longing for, and the levy of Liao is only an accidental move under the order.
Generally speaking, these two poems, "Dreaming of Jiangnan and conquering Liao is accidental", express the poet's love for Jiangnan and his helplessness in conquering Liao.
