After Cai Yong's death, warlords in Guanzhong area scuffled and Chang 'an people fled everywhere. Cai Wenji followed the refugees into exile. Xiongnu soldiers went south to take advantage of the fire and plunder the people. It was taken away by the Huns and became Zuo's wife. Maybe Cao Cao asked Cai Wenji because he knew Cai Yong and Cai Yong was more famous in Cai Wenji, and then asked for it back. Cao Cao arranged for Dongsi to marry Cai Wenji. Cai Wenji recited more than 400 ancient poems of China and wrote famous songs, such as Eighteen Beats by Hu Jia.

However, Cao Cao's family background is not so prominent, because of his grandfather's relationship, and even a little embarrassed. At that time, Cao Cao had certain attainments in calligraphy and chess, and later he took Cai Yong as his teacher. The two met because of their friend Qiao Xuan. Cao Cao asked Wenxi to write down his family's writings. Wenxi wrote more than 400 volumes, which is also the need of cultural reconstruction after Cao Cao unified the north! Under the aristocratic system in the Eastern Han Dynasty, Qiao Xuanguan was named Stuart, so after Cao Cao unified the north, he spared no expense to redeem her and marry Cai Wenji to Dong Si. Cao Cao fully sympathized with Cai Wenji. Dong Si was beheaded by Cao Cao for committing a crime, but Cai Wenji made a plea barefoot, and the tree wanted to die. Cao Cao was busy for a while, thinking about the daughter of old gay friends in that distant place. The sky was gray and boundless, which was really not a thing! The client brought some jewelry and the like to Zuo and tried to redeem it.

It is quite possible that Cao Cao and Cai Wenji have exchanged messages. It is estimated that the relationship is like a brother and sister, and of course there may be selfishness. Cai Wenji's father, Cai Yong, was a famous academic master in the Eastern Han Dynasty. Literature, calligraphy, astronomy, temperament, pervasive. He left more than 100 poems, and was also a bibliophile, with a collection of more than 4,000 precious books. For Cao Cao, an energetic man, it is not difficult to get married with Cai Wenji, but it is estimated that Cai Wenji got married later. After Cao Cao pacified the north, he got the news, missed the reason of making friends with Cai Yong, and sent Dong Si to the Xiongnu, holding a pair of gold and white jade, and invited Yue Ji back to Han. After Cao Cao as the intermediary, Moon Hee married Dong Si.
