Cold rain: cold rain in autumn and winter.

Furong Building: Formerly known as Northwest Building, it is in the northwest of Runzhou (now Zhenjiang City, Jiangsu Province). According to "Yuanhe County Records", Volume 26, Runzhou, Jiangnan Road, Danyang: "Jin is the secretariat, and the southwest building is called Wansui Building, and the northwest building is called Furong Building." Danyang is in the southwest of today's Jiangsu Province, with the Yangtze River in the northeast and the Grand Canal crossing obliquely. It belongs to Zhenjiang city, cold and rainy, and it is dark at night. Friends, if my friends in Luoyang invite me; Just say I'm still Bing Xin Okho, and stick to my faith!

Chushan: Chushan. Chu here also refers to Nanjing area, because Wu and Chu ruled here successively in ancient times, so Wu and Chu can be collectively called.

Wu: The names of ancient countries generally refer to southern Jiangsu and northern Zhejiang. During the Three Kingdoms Period in Zhenjiang, Jiangsu, the Furong Building in Wu Shizhong belonged to the northwest building, and the site was in the northwest of Runzhou (now Zhenjiang, Jiangsu). Boarding can overlook the Yangtze River and overlook the north of the Yangtze River. This poem was written around the twenty-ninth year of Kaiyuan. Wang Changling was in Jiangning (now Nanjing) at that time, and he became friends with Xin gradually. This time, he plans to cross the river from Runzhou, pass through Yangzhou and go north to Luoyang. Wang Changling may accompany him from Jiangning to Runzhou, and then break up here. The original title of this poem is * * *. The second poem is about the poet's farewell ceremony for Xin Xian in Furong Building the night before, and this poem is about the scene of leaving by the river the next morning.
