How can we see Sima Yi's cruelty through the handling of Cao Cao's stepson He Yan?

First, "This is a family that has been together for a long time."

After Sima Yan, Emperor Wu of the Jin Dynasty, came to the throne, he wrote a letter saying that his family "had children and raised children. This is not bragging, because the Sima family is also a family of poets and calligraphers!

In ancient China, the founding emperor would seal off his seventh ancestor, that is, his seventh ancestor (not counting the sixth generation), and Sima Yan, Emperor Wu of Jin Dynasty, was no exception. He is pursuing the seventh generation, among which his grandfather Sima Yi's great-grandfather Sima Jun is the first generation, Sima Yi's great-grandfather Sima Liang is the fourth generation, Sima Yi is the fifth generation, and his father and uncle are the sixth generation. On behalf of the Sima family, this is mainly because the Sima family started serving as officials according to Shi Kekao, that is, Sima Jun, the great ancestor of Sima Yi who was once the general of the Western Expedition; the second generation father Sima Liang, once served as the prefect of Zhang Yu; the third generation Sima Juan, once served as the governor of Yingchuan Grand Administrator; the fourth generation Sima Fang, courtesy name Jing Zhao Yin.

It should be said that the Sima family is a big family of ministerial-level cadres.

Second, "Sima Bada"

The Sima family was very proud when it was passed down to Sima Yi's father, Sima Fang. Sima Fang had eight sons, who were called "Sima Bada" because of the word "big" in his name, namely: Sima Lang, the governor of Yanzhou in the Han Dynasty, whose courtesy name was Boda; Wei Taiwei (Jin·)/Klock-1/ , the courtesy name; Wei Dazai (Jin'an Wang Ping) Sima Fu, the courtesy name Shuda; Wu Wei Dongchenghou Sima Yi, the courtesy name Jida; Wei Luhong, the courtesy name Sima Yi, has an outstanding character; Wei Zhonglang Sima Jin, the courtesy name is Huida; Wei Anchenghou Ting Sima Tong, the courtesy name Yada; Wei Anpinghou Ting Sima Min, courtesy name Judah.

Third, Sima Yi was also a "genius" when he was a teenager

In other words, Sima Yi was also a standard "angry youth" before the age of 20, "always worried about the country and the people" heart" and often criticize shortcomings. This is known to Yang, the governor of Nanyang. Yang Jun, who is known for his thoughtfulness, met Sima Fenqing and said that he was by no means an ordinary son. However, "Shang Shu·Cui Yan" made friends with Sima Yi's brother Sima Lang, but ruthlessly said to Sima Lang: "Your brother is smart, sensible, decisive and heroic, how can you compare with him?"! "

Fourth, Sima Yi assessed the situation and took refuge with Cao Cao, but was not taken seriously because of his appearance

During Sima Yi's life, the Han Dynasty declined and the world was in chaos. After Sima Yi assessed the situation, Cao Cao Determined to be a person who could stabilize the world, he did not serve as an official in the Han Dynasty, but joined Cao Cao and began to work as a chief clerk, which was equivalent to the secretary of the Prime Minister's Office. However, although Cao Cao appreciated Sima Yi's talent, he refused to reuse Sima Yi. It was all caused by Sima Yi's appearance.

This Sima Yi was born with a "wolf-like caring" look - he could hold his head and turn his head 180 degrees, like a wolf - it is said that this A person like this is disloyal and will eventually betray his master, so Cao Cao never reused him. Unexpectedly, the Sima family betrayed the Cao family in the end. Is this fateful retribution or Sima Yi's paranoid indignation towards Cao Cao? But it’s embarrassing!

Verb (abbreviation of verb) Sima Yi does not despise anyone with Cao Hong

The Cao family is often embarrassed by Sima Yi in the "Great Military Advisor Sima Yi Military Advisor Alliance", which is consistent with History. Cao Cao's brothers Cao Hong and Sima Yi despised each other when they were young, and Cao Hong also reported on Sima Yi.

According to "Wei Lue", Sima Yi was fond of learning, and Cao Cao liked to use swords. He studied, but Cao Hong had to ask Sima Yi for his opinion. Unexpectedly, Sima Yi looked down on Cao Hong and pretended to be unable to walk with a cane. Cao Hong hated this, so he went to Sima Yi to report to Cao Cao. He lost his crutch and went to see Cao Cao working for him. Cao Cao laughed it off, and the grievances between Cao Hong and Sima Yi were connected.

Sixth, if you want to assist Cao Yu, you must do odd jobs

Sima Yi does not like Cao Cao. He was highly regarded and went to Cao Pi to help Cao Pi win the throne. From then on, he gained Cao Pi's trust.

One of Sima Yi's talents is that his military predictions can be described as perfect.

Cao Cao was threatened because the capital was Chang'an, which was close to Fancheng. He was going to move the capital. Sima Yi dissuaded him and said, "Now that Guan Yu is an older child, Sun Quan will definitely be even more unhappy. Liu Bei has not returned to Jingzhou for a long time, and Sun is trying to find a way to deal with Guan Yu; I am very proud now, and I am not far from failure.

Let’s sit down and see, why move to the capital? "This time Cao Cao listened to him, and later Sun Quan sent Monroe to attack the police, and Guan Yu was captured and killed by him.

Afterwards, Cao Cao thought that the survivors of Jingzhou and the soldiers and civilians of the Yingchuan army had approached the Nanman bandits and wanted to attack them. Drive away. Sima Yi thought: "Jingchu is easy to move and difficult to rest. Guan Yu is the new one, and they are all hiding and watching the evil people. If you do well at this time, it will hurt your intentions and make people who leave afraid to come back. "Cao Cao adopted his suggestion and did not immigrate. In the past, all fugitives from Tibet came back and became naturalized.
