Brief introduction of Cao Cao's life?

Cao Cao (155-220) was a politician, strategist and writer in the late Eastern Han Dynasty. Formerly known as Xiahou, the word Meng De, nicknamed Ayun. He was born in Peiguoqiao County (now Bo County, Anhui Province), the eldest son of a big bureaucratic landlord family. Because his father, Cao Song, is the adopted son of Cao Teng, China's constant servant, he changed his surname to Cao. Because of this relationship, Cao Cao had the opportunity to get in touch with bureaucratic children from an early age. Yuan Shao, the future enemy, is also a friend of Cao Cao when he was young. Cao Cao is seven feet long with fine features and a long beard. I grew up bohemian, but I am very talented, resourceful and good at improvisation. At that time, there was a famous person in Runan who was very good at judging people, named Xu Shao. He commented that Cao Cao was a "capable minister who managed the world and a traitor in troubled times".

After the death of Emperor Ling of Han Dynasty, the general took charge of state affairs as a consort. But when he killed the eunuch, he was ambushed. At this time, Dong Zhuo, who has the title of Wolf of the West, led the army to take over the capital. Zhuo entered the city and changed to Shao's younger brother Liu Xie. Most ministers fled Luoyang in succession. Cao Cao also fled to Liu Chen to gather volunteers and condemn Dong Zhuo.
