The story of Cao Cao and Cai Wenji?

1. In the 11th year of Jian'an (207), Cao Cao always loved literature and calligraphy, and often had literary and calligraphy exchanges with Cai Yan's father, Cai Yong. When Cao Cao saw that Cai Yong had no heirs, he used a golden jade to redeem Cai Yan from the Xiongnu and married Cai Yan to Dong Si.

2. Then Dong Si committed a capital crime, and Cai Yan went to Cao Cao to intercede for Dong Si. At that time, Cao Cao was hosting a banquet for officials and distinguished officials, and said to the guests in the hall: "Cai Yong's daughter is outside. Let everyone see her today." Cai Yan, with his hair disheveled and barefoot, kowtowed to apologize, spoke clearly and clearly, and was filled with emotions and sorrow. They were all moved by it. But Cao Cao said: "But the document of condemnation has been sent out, what should I do?" Cai Yan said: "You have thousands of good horses in your stable, and countless brave soldiers, but you are stingy with a fast horse to save you." A dying life?" Cao Cao was finally moved by Cai Wenji and pardoned Dong Si.
