Historical Information
Born in Nan Commandery, Lady Cai's marriage to Liu Biao made her clan a powerful influence within his court. She constantly favored Liu Cong and slandered Liu Qi due to the former's wife being her niece. By collaborating with her younger brother Cao Mao, the two of them were able to install Liu Cong as the new governor of Jing.

Romance of Three Kingdoms
In the novel, Lady Cai is considered the biological mother of Liu Cong, hence fueling her motivation to instate her son. When Liu Bei was welcomed to Jing by Liu Biao, she and Cai Mao feared his presence would jeopardize their clan's standing. Lady Cai in particular became more distrustful of Liu Bei upon overhearing his private conversation with her husband. She passed this information to her brother who made plans to assassinate their guest. However, the plot backfired when Liu Bei caught wind of it and fled. Liu Biao, who had been deceived by the Cai faction regarding this incident, became indignant upon learning the truth and would have executed Cai Mao if not for Sun Qian's intervention.

When Liu Biao grew ill, he assigned Liu Bei stewardship over his chosen successor Liu Qi. This infuriated Lady Cai who confided with her cohorts to prevent father and son from meeting. After Liu Biao's passing, they created a forged document to ensure that Liu Cong would become governor instead. Their machinations would not last as news of Cao Cao's army approaching Jing reached the ears of the Cai faction. Eavesdropping on her son's concerns with his advisers, Lady Cai implored him to follow their advice and surrender. After meeting Cao Cao, she and Liu Cong were relocated to Qing Province in northern China. On their way there, they were both killed by Yu Jin who had been ordered by Cao Cao to assassinate them.
