Cai Wenji's literary achievements mainly include his two sorrowful and indignant poems, a five-character poem and a Sao poem. Among them, Wuyanben, which focuses on Sentimental Parting, is an emotional narrative poem and the first autobiographical long narrative poem written by literati 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.
Cai Wenji's achievement in music is mainly his eighteen beats of Hu Jia, which is a lyric poem of ancient China Yuefu with the word 1297. This is a vocal divertimento composed of eighteen songs.
Cai Wenji has also made some achievements in calligraphy. Cai Yan's father, Cai Yong, is a great calligrapher. He created eight-point fonts. Cai Yan's handwriting is also very good. Han Yu once said: "The corps commander (Cai Yong) has a woman who can carry on the family line." Cai Yan once wrote ancient books silently at the request of Cao Cao, saying that he could write both portrait books and cursive scripts.
