Cai Wenji was redeemed by Cao Caohua. Why didn't Cao Caohua take her as his own?

One of the four talented women in China, Cai Wenji, whose name is Cai Yan, is the daughter of Cai Yong, a great writer in the Eastern Han Dynasty. Influenced by her father, she studied and wrote well since childhood, and was good at poetry and prose. She is also good at literature, music and calligraphy. However, Cai Wenji may be jealous of talented people, but her married life is not satisfactory.

Cai Wenji married Wei Zhongdao in his early years. The Wei family is a family in Hedong with a high reputation, and Cai Wenji is a famous Confucian daughter, a talented woman, which is a match made in heaven. However, the good times did not last long. One year after Cai Wenji's marriage, her husband died of illness. Cai Wenji didn't want to endure the painful situation of her husband's family, so she went home and lived alone, singing poems and writing compositions all day.

Later, the Huns invaded the Central Plains. When the Huns heard about Cai Wenji, they took her away and took Cai Wenji away. During the twelve years of Xiongnu in Cai Wenji, they endured humiliation day by day and gave birth to two children.

Cao Cao always likes to understand people. He heard that Cai Yong was very talented and often called him to exchange literature and calligraphy. Later, Cao Cao heard that Cai Yong's only daughter, Cai Wenji, was captured, and Cai Wenji was also a famous talented woman at that time. Cao Cao paid a lot of money to redeem/klock -/ from Zuo.

as we all know, Cao Cao loves beauty only when he loves it. He has been married many times. Mrs. Huan, Mrs. Du and Mrs. Yin all remarried to Cao Cao's concubines, while Cai Wenji was both talented and beautiful. Cao Cao spent a lot of money to redeem her, but instead of keeping her for herself, she was engaged to Dong Si. Why?

First of all, Cao Cao and Cai Yong are friends and respect Cai Yong very much, so because of their relationship with Cai Yong, he dare not do such shameless behavior. In addition, Cai Wenji itself is very famous. Cao Cao will be criticized for marrying her, and Cao Cao himself doesn't want to ask for unnecessary trouble. But Cao Cao still kept one hand, that is, betrothed her to his subordinate Dong Si. On the one hand, he can win people's hearts, on the other hand, he can keep Cai Wenji under his own banner.

Later, Dong Si committed the death penalty, and Cao Cao ordered the execution. Cai Wenji came out barefoot and begged Cao Cao to kowtow and pardon Dong Si's death penalty. Cao Cao was moved by Cai Wenji's words and deeds and saved Dong Si's death. After returning to China, Cai Wenji wrote two poems of grief and indignation, which became masterpieces handed down from generation to generation, but there is no record about her since then.
