Strictly speaking, Cao Cao (born in July of 155, 18 ~ died in 220) was a figure in the late Eastern Han Dynasty. The Eastern Han Dynasty: 25-220 witnessed the formal division of the Three Kingdoms and the demise of the Eastern Han Dynasty: 220-280 witnessed the beginning of the Yellow turban insurrectionary in February 184, which was also called the Three Kingdoms. Therefore, it can also be called a figure in the late Eastern Han Dynasty and the Three Kingdoms period. (But this statement is not quite correct. )
Satisfied, please adopt.
