Diaochan 貂蟬

Diao Chan (or Diaochan) is a fictional character from the novel Romance of the Three Kingdoms a.k.a. Sanguo Yanyi. The character Diao Chan is based on a historical character; a maid under employance of Dong Zhuo who had an affair with Dong's general Lü Bu.

Life
Historically not much is known about Dong Zhuo's maid, fictionally named Diao Chan (her real name is not recorded). Diao Chan's stories in Romance of the Three Kingdoms or any of the videogames are all fictional.

Affair with Lü Bu
During the Campaign against Dong Zhuo, "Diao Chan" served Dong Zhuo as his maid. She was most likely of young age. She met Lü Bu when Dong Zhuo had ordered him to guard the palace doors. "Diao Chan" was presumably a girl of pleasant appearance, because whenever she passed by the palace doors, Lü Bu would attempt to seduce her, eventually succeeding. In 193 A.D. "Diao Chan" and Lü Bu had an affair. The affair unsettled Lü Bu. Once, Dong Zhuo had tried to kill Lü Bu by throwing a lance aimed at his head for a minor offence. Lü Bu always feared Dong Zhuo would do something like that again, given Dong Zhuo's temper. Presumably, he feared that the chances of something like that happening again would become bigger if Dong Zhuo found out about his affair with "Diao Chan".

Wang Yun's involvement
Minister over the Masses, Wang Yun had noticed the changes in the relationship between Dong Zhuo and Lü Bu (which had changed partially because of "Diao Chan") and used it to set Lü Bu up even further against his adoptive father, which ultimately resulted in Lü Bu killing Dong Zhuo. What happened to "Diao Chan" after this is not known.

Family
