This poem was written in the first year of Tianbao (AD 742), when Wang Changling was Jiangning Cheng. Xin gradually is a friend of Wang Changling. This time, he plans to cross the river from Runzhou, pass through Yangzhou and go north to Luoyang. Wang Chang may accompany him from Jiangning to Runzhou, and then break up here. This poem was written for the parting river.
This poem is a farewell poem. "Cold and rainy nights enter Wulianjiang", misty rain hangs over Wu's river surface, weaving an endless network of worries. The rainy night adds to the bleak autumn.
