Cai Wenji (date of birth and death unknown), named Yan, was born in Chenliuyu, and was the daughter of Cai Yong, a great writer of the Eastern Han Dynasty. She is a rare talented woman in the history of Chinese literature. She is good at music, literature and calligraphy. The story of playing the piano at the age of six has been passed down through the ages. He went through ups and downs in his life. He first married Wei Zhongdao and became a widow. Later, he was taken captive to the Southern Huns during the war for twelve years and gave birth to two sons. After Cao Cao unified the north, he paid a lot of money to redeem her, which became the allusion of "Wen Ji returned to the Han Dynasty". Her five-character masterpiece "Poetry of Sorrow and Indignation" is China's first autobiographical long narrative poem written by a literati. Although the qin song "Eighteen Beats of Hujia" is suspected of being fake, it vividly interprets her cultural journey across the Hu and Han Dynasties. After returning to the Han Dynasty, he silently wrote more than 400 pieces of Cai Yong's posthumous works, making an indelible contribution to the inheritance of Chinese culture.
