Cao Cao likes wives for a long time. He has a special interest in this type of girls. Moreover, Cao Cao loves talents, and Cai Wenji is also very talented. Therefore, it is reasonable for Cao Cao to admire Cai Wenji.
Cai Wenji’s name is Cai Yan. The word Wenji.
Cai Wenji’s father is a great writer who created the eight-point font. and great calligrapher. He was a great leader in the literary world at that time and was proficient in astronomy and geography. There is also some research on music.
Because of the strong family background. Therefore, Cai Wenji has been influenced by her ears and eyes since she was a child, and she is also good at literature and calligraphy. He can understand music and can also identify sounds and compose music.
As a lady from a famous family, Cai Wenji married the prestigious Wei family son. The husband is Wei Zhongdao, the second son of the Wei family. This young couple lived in harmony and loved each other, but their good times did not last long. Wei Zhongdao died young due to illness. Cai Wenji became a widow and returned to her parents' home. Later, Cai Wenji's father was arrested. Cai Wenji's family became separated during the war and chaos. Cai Wenji was captured as a slave and went to the Southern Huns. Married to King Zuoxian and raised two children.
More than ten years later, Cao Cao unified the north. Cao Cao liked literature very much and often went to Cai Wenji's father for advice. Cai Yong had no son but his only daughter. He also disappeared, so Cao Cao sent people to help search everywhere. I heard about it later. The princess of King Zuo Xian was from the Central Plains. After asking around, she turned out to be Cai Wenji. So Cao Cao sent an envoy to redeem Cai Wenji from the Xiongnu with a lot of money.
This fate is really tricky for Cai Wenji. On the one hand, there is his hometown and his old father. On the other hand, there are my two children. But he finally chose to return to Han. We don't know how she felt when she came back, but she wrote her eternal masterpiece "Eighteen Beats of Hujia".
The Cai family had a large collection of books, but they were all lost after the battle. Cao Cao loved literature, which was a pity. Cai Wenji said that I can recite more than 400 of them. So Cai Wenji relied on her memories from long ago and wrote down more than 400 ancient books, not missing a word.
As for why Cao Cao likes Cai Wenji so much but doesn't marry her yet. I think there are the following points. First, Cai Wenji is the daughter of a writer he respects. Secondly, use Cai Wenji to win over talented people. In the end, he was the one who redeemed Cai Wenji. If he had a bad reputation in his name after taking concubines.
As modern people, we cannot judge how Cao Cao wanted to treat Cai Wenji at that time. However, judging from the historical legacy, Cao Cao did protect Cai Wenji and took good care of her.
