The second is that the political ambition is reunification. His main energy was devoted to the great event of reunification, whether it was to let the princes go south with the help of the emperor or to go out in person, it was for this purpose. As for calligraphy or literature, it is only an episode in which a politician's occasional interest leads him to talk about things. His political efforts made the Cao Wei regime the most powerful in the Three Kingdoms period, both in terms of talents and military strength.
Cao Cao's calligraphy is still very powerful. Shu Duan thinks these two words are wonderful. Whether these two words are wrong or not (personally, it is very unlikely that people like Cao Cao will make typos), we can see from these two words that they are vigorous and powerful, and there are still two brushes that can become one of the five great calligraphers. Cao Cao is not a hero in the Romance of the Three Kingdoms, but a very kind prime minister (even if he died, he still didn't claim to be the emperor).
Cao Cao, a character vilified by novels, has a good environment under his rule, at least better than Liu Bei's Shu-Han regime. They fought for several years, and the people were miserable. It was finally destroyed in Liu Chan, which is an advantage. Otherwise, people will suffer. what do you think?
