Sima Yi, on the other hand, strictly controlled the emperor ICY in the imperial court, and as the leader of the aristocratic families in the world at that time, it can be said that most people who held power in the imperial court were biased towards Sima Yi.
In fact, the decline of Cao Zhi's clan has long been obvious to all, because at that time, in order to attack the prestige of the powerful clan family at that time, Cao Wei used aristocratic men and squeezed out clan ministers, which led to these aristocratic families headed by Sima Yi gradually stepping onto the historical stage and mastering part of the power of Cao Wei's regime, which also led to the failure of aristocratic families, so the early days of the founding of Wei began.
In fact, if Xelloss or Cao Cao can live longer, maybe they can handle these problems by their own means, so that young Cao Fang will not be firmly controlled by those people between the imperial courts when he acceded to the throne. In fact, in the final analysis, the reason why Sima Yi was finally in charge of state affairs was attributed to Cao Pi's excessive attack on the clan.
