In the novel, Wang Yun devised an elaborate plot to eliminate Dong Zhuo. It involved two of the Thirty-Six Stratagems: Beauty Trap and Chain Stratagems.
In Chapter 8, Wang Yun was thinking about how to get rid of Dong Zhuo when he encountered Diaochan, a singer in his household whom he had been treating like his daughter. An idea struck him: Make use of Diaochan to sow discord between Dong Zhuo and Lü Bu, and instigate Lü Bu to assassinate Dong Zhuo.

He then invited Lü Bu and Dong Zhuo to his residence for a party on two occasions. On both occasions, he asked Diaochan to perform for the guest and catch his attention. He initially promised to marry Diaochan to Lü Bu; later, he let Dong Zhuo bring Diaochan home. When Lü Bu found out, he suspected that Dong Zhuo had seized Diaochan for himself and became very angry.
・suspect that... は「……ではないかと疑う（≒……だと思う）」，doubt that... は「……であることを疑う（……だとは思わない）」です。
One day, while Dong Zhuo was out, Lü Bu sneaked into his room to meet Diaochan. She wept and pleaded with him to save her from Dong Zhuo. In the meantime, Dong Zhuo had returned and he saw Lü Bu embracing Diaochan. He was so furious that he threw a ji at Lü Bu which narrowly missed him as he fled. After calming down, Dong Zhuo spoke to Diaochan and asked if she was willing to marry Lü Bu, but she said she would rather die and attempted suicide. Dong Zhuo then believed her.
In Chapter 9, as Lü Bu became increasingly resentful of Dong Zhuo, Wang Yun used the opportunity to instigate and incite Lü Bu to turn against Dong Zhuo. Wang Yun managed to convince Lü Bu to kill Dong Zhuo, and then set up an ambush near the palace gates. He then lied to Dong Zhuo, saying that Emperor Xian wanted to abdicate his throne to him, and lured Dong Zhuo into the ambush, where he met his end at Lü Bu's hands. Later in Chapter 9, when Chang'an was surrounded by Li Jue and Guo Si's forces, Wang Yun made them promise to not harm Emperor Xian and then committed suicide in front of them by jumping off the viewing platform above the city gates.
第9章（除暴兇呂布助司徒 犯長安李傕聴賈詡）で，呂布がますます董卓への怒りを募らせると，王允は機会を用いて呂布が董卓に反抗するようけしかけました。王允は呂布に，董卓を殺すよう説得することに成功し，宮殿の門の近くで待ち伏せ（ambush）するよう計画しました。それから彼は，献帝が董卓に帝位を譲りたがっていると言って董卓に嘘をつき（lie to...），董卓を待ち伏せ場所に誘きだし（lure），そこで董卓は呂布の手にかかり最期を遂げました。第9章の後半で，長安が李傕・郭汜の軍に包囲されると，王允は彼らに，献帝を傷つけないと約束させ，彼らの前で城門の見張り台から飛び降りて自決しました。
After Dong Zhuo's death, Lü Bu marries Diaochan and flees Chang'an with her when he is defeated by Dong Zhuo's former followers.
In the later novel, Diaochan has only a cameo in the Battle of Xiapi, and is not mentioned again thereafter.
