Cao Cao was not a man from the Three Kingdoms period? At the end of the Han Dynasty, people did not know about the Eastern Han Dynasty at all, only the Three Kingdoms

In 215 AD, the territory of the Three Kingdoms was basically demarcated, it had been 7 years since the Chibi War, Cao Cao was still alive, although he did not officially ascend the throne and change the name of the country, in fact, the Han Dynasty had long existed in name only, and the military and political power was divided into three worlds.

In 220 AD, Cao Cao died of illness at the age of 66, and Cao Pi succeeded to the Wei Dynasty and Cheng Xiang in the same year

Cao Pi usurped Han and forced Emperor Liu Xiechan of Han to give up the throne, followed by Liu Bei in 221 and Sun Quan in 229.

Look at the ancients at that time, even the Europeans did not see, but also had to let the Roman Empire, the American Indians recognize the three kingdoms? Send ambassadors to each other, build consulates? That is the concept of the state is to divide the regime, and the borders are roughly demarcated.

The Eastern and Western Han Dynasties are divided by historians, that is to say, at the end of the Han Dynasty, people did not know the Eastern Han Dynasty, only knew that there were three kingdoms, and now people are a bit bookish and impose consciousness on the ancients.

So Cao Cao was a pan-Three Kingdoms era man! He was a politician, military man, and literary calligrapher born at the end of the Eastern Han Dynasty.
