How did Zhuge Liang, Cao Cao and Sima Yi educate their sons during the Three Kingdoms period?

Their educational methods are all different. Zhuge Liang's education method is still kind, but compared with Cao Cao and Sima Yi, he pays more attention to the ideological education of his son. And Cao Cao is to let his sons progress from competition; What is more terrible than Cao Cao is Sima Yi's educational method. He taught his sons to forbear, make them lose face, and pay more attention to cultivating their sons' scheming. It still sounds terrible.

Zhuge Liang can be said to be a treasure house of wisdom. Liu Bei once came to the cottage and invited him out of the mountain, which shows how attractive he is to power seekers. While assisting Liu Bei, Zhuge Liang made suggestions for him, such as burning red cliff and borrowing arrows from grass boats, which made great contributions to Liu Bei's farmland. Zhuge Liang devoted himself to his career all his life and worked tirelessly. His education of his son is even more admirable. He pays more attention to his son's ideological education, so that his son can cultivate his body and mind, study hard, set up lofty aspirations and cherish time. In the eyes of others, he is a fatherly figure.

And Cao Cao has long been known to everyone, and everyone can see clearly that he is ruthless and scheming. Of course, this also exposed his cruelty and harshness in educating his son. He once wrote Tong Ling to educate his son and encourage him to make progress through competition. Of course, I'm not saying that this way is not good, and proper competitive pressure will promote people's progress, but from Cao Cao's point of view, his extreme competitive way is undoubtedly pushing his son against the wall.

The most terrible thing is Sima Yi. For his own sake, he taught his son to learn to be forbearing and not to show his emotions. The son educated in this way is very calculating, which we will see later.
