Death of Dong Zhuo
Dong Zhuo was the famous tyrant that arose in the late Eastern Han. Many attempts to assassinate him failed, including Cao Cao's attempt. Finally, when everything seemed to be of no use, the official, Wang Yun, used a maiden in his house, Diao Chan, to put into action a beauty trap on Lu Bu and Dong Zhuo. As both men became quite fond of the maiden, they were not sure how to settle the matter. Diao Chan used this opportunity to worsen the situation by complaining about to Lu Bu and Dong Zhuo of the other. Eventually, hot tempered as Lu Bu was, he assassinated Dong Zhuo.
