昔者，蔡琰归于曹公，甚得其宠。然其父邕，因董卓之乱而亡。琰常怀悲痛，思亲不已。一日，曹公欲杀一囚犯，琰闻之，乃上前求情曰：“妾父邕，曾为国之栋梁，今妾虽蒙公恩，然父仇未报，心实难安。此囚犯虽有罪，然若能赦之，令其改过自新，则亦不失为国之用也。”

曹公听罢，深感其言有理，遂赦囚犯。囚犯感恩戴德，誓死效忠曹氏。

翻译如下：

In ancient times, Cai Yan returned to Lord Cao and gained his favor greatly. However, her father Cai Yong had died due to the chaos caused by Dong Zhuo. Cai Yan often felt sorrowful and missed her father dearly. One day, Lord Cao decided to execute a prisoner, and upon hearing this, Cai Yan stepped forward to plead for mercy: "My father Cai Yong was once a pillar of our country, and even though I have received your grace, my heart is unsettled as my father's vendetta remains unavenged. This prisoner, although guilty, if spared and given the chance to repent and reform, could still be useful to the state."

Lord Cao, upon hearing her words, found them reasonable and thus pardoned the prisoner. The prisoner, grateful for the mercy shown, swore eternal loyalty to the Cao family.
