The clouds fall in the sky and the moon rises in Jiugao, from the second poem of "Two Orchid Pavilion Poems" by Sun Chuo of the Jin Dynasty. Sun Chuo (314-371), courtesy name Xing Gong, was a famous representative of Xuanyan poetry in the Eastern Jin Dynasty. He was a native of Zhongdu, Taiyuan (now Pingyao). Sun Chuo's literary talent was said to be unparalleled at that time. He had a good relationship with the famous calligrapher Wang Xizhi, and everyone who got Sun Wen's calligraphy was proud of it. When Shi Shi was the commander of the Youjun Army, he made friends with Wang and got along well with him. The epitaphs and inscriptions of important officials and celebrities in the court, such as Yin Hao, Huan Wen, Yu Liang, etc., were all written by him.
