When describing a person's obvious ambition, why is it often said that everyone knows Si Mazhao's heart?

If you want to know why Si Mazhao reminds you of the word ambition, you should know the social environment in which Si Mazhao lived at that time. Si Mazhao is wei ren. At that time, Wei's Sima family was the head of the family, but Si Mazhao's relatives died one after another. Si Mazhao's father Sima Yi is a general of Wei. At that time, Sima Yi dominated Wei for a while, but Sima Yi died soon after taking power.

After Sima Yi's death, he did not show the greatness of Si Mazhao, because the eldest son inherited it at that time, so Si Mazhao's younger brother Sima Shi took over the power of his father. Soon Sima Shi showed extraordinary political talent. He abolished Cao Fang, who could not lead the government, and made thirteen-year-old Cao Mao emperor, in order to better control the state power of Wei. But Sima Shi soon became seriously ill and had to hand over the power to Si Mazhao.

And Si Mazhao deserves to be the blood of Sima family. After taking power, he was even more fighting than his brother, which made Cao Mao, who had just proclaimed himself emperor at that time, feel afraid. Because Cao Mao knew that every time Si Mazhao looked at himself, his eyes burned with ambition, and Si Mazhao wanted to be his own emperor instead. So Cao Mao thought for a long time and decided to strike first. He called his confidant minister to a secret meeting: "Everyone knows Si Mazhao's heart. I can't let him overthrow me for nothing. I want to kill him first. " However, several ministers knew that more than half of the imperial court now belonged to Si Mazhao, so they tried their best to dissuade Cao Mao from doing so.

However, Cao Mao, a newborn calf who is not afraid of tigers, cannot learn to hide his strength. He still carried out the plan, but Si Mazhao knew it before it was implemented. Si Mazhao was ruthless. He killed Cao quietly. Si Mazhao was not only ambitious at home, but after killing xelloss, Si Mazhao captured the rulers in one fell swoop and wanted to unify the whole country. This shows Si Mazhao's great ambition, which is one of the reasons why later generations always use Si Mazhao to describe his ambition.
