Cao Cao and Cai Wenji are close friends. If conditions allowed, they might be a couple that everyone would envy, but due to a strange combination of circumstances, the two were destined to be together but not destined to be together. Even so, Cao Cao took more care of Cai Wenji for the sake of his old friend Cai Yong. I would rather betray the world than let the world betray me? This is a famous saying of Cao Cao during the Three Kingdoms period. From this sentence, it is not difficult to find that he is a selfish hero. But such a selfish person showed his sincerity to Cai Wenji. There is the friendship between friends and the sympathy of "beauties love heroes".

Cai Wenji's father, Cai Yong, was a famous writer during the Three Kingdoms period. Under his father's influence, Cai Wenji was proficient in all kinds of music, chess, calligraphy and painting. Therefore, Cai Wenji is very famous. Many great talents and heroes during the Three Kingdoms period admired Cai Wenji. At this time, Cao Cao, who was more than 20 years older than Cai Yong, was still just a junior "entrepreneur" whose career had improved. Perhaps because of low self-esteem or other reasons, he did not express his love to Cai Wenji.

In this way, the two missed each other. Cai Yong saw that his daughter was getting older, so he decided to marry Cai Wenji to Wei Zhongdao, a famous student at the time. Unexpectedly, Wei Zhongdao died soon, and her husband's family accused Cai Wenji of killing her husband. Cai Wenji was a very proud person. She couldn't stand the cold looks and accusations from her husband's family, so she ran back to her parents' home. During the subsequent invasion of northern nomads, she was kidnapped and made the concubine of the Hu people.

Twelve years later, Cao Cao, who had become the overlord of the north, spent a lot of money to redeem Cai Wenji, and personally designated her marriage and married her to Dong Si. Later, Dong Si broke the law and Cao Cao wanted to kill him. Cai Wenji came to plead for mercy. As a last resort, Cao Cao pardoned him. The murderous Cao Cao actually changed his mind for Cai Wenji. This is definitely an unprecedented first time. From this, we can also see Cao Cao's sincerity towards Cai Wenji. Perhaps, Cai Wenji also knew that she and Cao Cao had a "fate-related" relationship, so she came to ask for mercy.

To sum up, Cao Cao and Cai Wenji are a pair of close friends who are destined but not separated, and they are full of entanglements.
