Is it true that Cao Cao assassinated Dong Zhuo?

It is not true that Cao Cao assassinated Dong Zhuo. In the official history, Cao Cao did not assassinate Dong Zhuo. This story originated from the novel Romance of the Three Kingdoms. Cao Cao, an official history expert, saw Dong Zhuo's perverse behavior and was unwilling to cooperate with him, so he changed his name and surname and escaped from Luoyang (now Luoyang East), the capital of Beijing.

Cao Cao (155-0315,220) was born in Mengde, a lucky man and a small character, Asan, from Peiguoqiao County (now Bozhou, Anhui Province). At the end of the Eastern Han Dynasty, he was an outstanding politician, strategist, writer and calligrapher, and the founder of the Cao Wei regime in the Three Kingdoms.

Dong Zhuo (? -1May 22, 1992), whose name was Ying Zhong, was born in Lintao (now Min County, Gansu Province) and Yingchuan. At the end of the Eastern Han Dynasty, when he was a powerful minister and the official was a surname, he was appointed as Hou.
