This poem was written in the 14th year of Kaiyuan (726), when the poet first arrived in Jinling. The West Tower of Jinling City, namely "Sun Chuta", was named after the poet Sun Chu of the Western Jin Dynasty came here to climb and chant. This poem was quoted in Ding Jing Health Records, Volume 21, "Li Bai Restaurant", and immediately went to the Sun Kitchen Restaurant in the west of the city. The textual research of this volume says: "Li Bai played in Yuexi Sun Chu Restaurant, sang at night, drunk with purple Qiu Qi and black shawl, sang with several drinkers beside Qinhuai, and visited Cui Si to wait on the court. Li Baiyou said in a poem,' Sell Jinling wine in the morning and sing about Sun Chulou.' "
Chengxi Sun Kitchen Restaurant is located on Fuzhou Mountain in the northwest of Jinling City. The winding city walls and the vast Yangtze River are at the foot of Chen Qi, making it a scenic spot. This poem is what Li Bai saw and felt when he wrote about the night tour of the West Building, and it expressed Li Bai's reverence and admiration for Xie Shu, a poet of the Southern Qi Dynasty.
