After the Han Dynasty, Yan Hui wrote two poems of mourning and anger, a poem of five characters and a poem of Sao style. [6] The first five-character poem, with the theme of "sentimental separation", is a sentimental narrative poem and the first autobiographical long narrative poem created by a scholar in the history of China poetry. Zhang Yugu, a poetic theorist in the Qing Dynasty, once wrote a five-character poem praising Cai Yan: "Wenxi only wants to crush Wen Jun, and' grief and indignation' is long. The old Du family lived in the Seventh Division of Cao Cao, and the incense can also reach the hairpin skirt. " Cai Yan's talent overwhelmed Zhuo Wenjun, a talented woman in the Han Dynasty, and the five-character narrative poems of Cao Zhi and Du Fu were also influenced by Cai Yan.
Sorrow and indignation poems, written in Sao style, are aimed at expressing emotions. The first and second sections briefly describe the experience of Hu and his son being captured in Han Dynasty, and in the middle, a large part of natural scenery is used to render Cai Yan's sad mood of leaving his hometown. In these descriptions of scenery and human feelings, Chae Yeon talked about their differences from her hometown of China, in order to describe her deep sadness and indignation in this different environment from China.
