If you don't compare yourself with others, just compare it with the process of the Cao family gaining the world, you know how disgraceful the Sima family's heavenly descent is.
Under what circumstances did Cao Cao raise an army? It was after Dong Zhuo's disaster in the imperial court, when the princes from all over the country rose up to attack Dong Zhuo, and when Kuang Fu Han was in the Han Dynasty, Cao Cao ran out of Luoyang, returned to his hometown, recruited people and horses as primitive stocks, and began to raise troops to fight the world, defeating countless princes of all sizes along the way, and finally unifying the north and establishing the foundation of Cao Wei.
It is said that Cao Cao blackmailed the Son of Heaven to order the princes, so how did Cao Cao threaten the Son of Heaven? Deposing The Young Emperor and establishing Emperor Xian instead was Something Dong Zhuo had done and had nothing to do with Cao Cao. Emperor Xian of Han was taken hostage by Dong Zhuo to Guanzhong, and after Dong Zhuo's death, there was great chaos in Guanzhong, and Emperor Xiandi of Han fled from Guanzhong with his courtiers and ran to Luoyang, where he could not even eat, and it was Cao Cao who sent someone to take Emperor Xian of Han to his territory xuchang.
When Emperor Xian of Han arrived in Xuchang, although nominally most parts of the country still recognized his identity and status, who cared about him? It was just a mascot, he had no ability to control the situation in the country, and no one listened to him. When he came to Cao Cao's territory, Cao Cao was kind to him, he was the emperor, Cao Cao had black spots, what method did he use to make him collapse, or simply like Dong Zhuo, deposed him, what ability did he have to resist?
Cao Cao's territory was all laid down by himself, little by little, and one prince after another was destroyed. Although Cao Cao did not take Emperor Xian of Han too seriously, and indeed he was also a powerful vassal, his territory was not snatched from the hands of the Han Dynasty, but the Han Dynasty itself lost it, and Cao Cao went to grab it back. If Cao Cao were to return the high wind and bright festival to the Han Dynasty, it would be a good character for others, and if he did not return it, others would not be able to say anything.
What does this mean? For example, during the War of Resistance Against Japanese Aggression, the Nationalist army was gradually defeated and retreated, and the national territory was lost, and then the Eighth Route Army and the New Fourth Army advanced behind the enemy lines, established a large number of base areas, and persisted in resisting Japan. After the end of the War of Resistance Against Japanese Aggression, Chang Gong stood up and said, This is my territory, you stole it, and now you must return it to me. Why? The land stolen from the Japanese, why did you say you wanted it to give it to you?
In this way, Cao Cao did not depose the emperor, and the second did not disrespect the Han Xiandi emperor in face, and did not usurp the throne until his death, but first sealed the Duke of Wei, and then entered the Wei King, making some preliminary preparations for the usurpation. When others persuaded him to be zen, he only said that if the Mandate of Heaven was indeed mine, I would be the King of Zhou Wen myself. This means that he is still willing to continue to maintain his status as a monarch of the Han Dynasty, and if his descendants want to usurp the throne, then let them do it.
The Sima family was different. Although Sima Yi was also considered to be the elder of Cao Wei, when he joined the shares, Cao Cao's basic disk was already very stable, and his contribution was limited. By the time of Cao Pi, there were not many opportunities to restrict his use. When Cao Pi was dying, he let him and Cao Zhen assist the government together, and after Cao Zhen's death, Cao Rui also pinched him to death, and he did not have much chance to turn over.
Until Cao Rui was dead, the Cao family really did not have any available talents, and it was Cao Shuang and Sima Yi's turn to assist the government. Cao Shuang is indeed a misdemeanor, is a courtier, this is no problem, but at least nominally, he is still cao's own family, even to the time of the gaopingling change, Cao Shuang also controlled the emperor, Sima Yi raised an army to control the capital, this is not only against Cao Shuang, do you take the emperor in Cao Shuang's hands as a person?
There were also those Cao Wei elders who supported him at that time, originally thinking that Sima Yi would take the lead and take back Cao Shuang's power and let Cao Wei return to a normal state, but the result was that Sima Yi not only wanted Cao Shuang's power, but also Wanted Cao Shuang's life, and even Jiang Ji, who had persuaded Cao Shuang to give up resistance, could not look at it. Sima Yi not only replaced Cao Shuang himself, but also was too much more than Cao Shuang, Cao Shuang just wanted power, and Sima Yi was directly fatal.
When Sima Yi died, Sima Shi began to become Dong Zhuo himself, deposed Wang Fang of Qi, and established Cao Xian as the Duke of Guixiang, and then continued to use the excuse to kill the ministers of culture and martial arts who were still loyal to Cao Shi, and this was how the three rebellions in Huainan came, Sima Yiping, Sima Shiping, and Sima Zhao. After Sima Zhao took power, it was even worse, and he directly stabbed Emperor Cao Xian to death on the street. The whole process of the Sima family usurping the throne is the process of bullying other people's orphans and widows.
Therefore, after the fall of the Western Jin Dynasty and the establishment of the Eastern Jin Dynasty, the Sima family's own descendants, Emperor Ming of Jin, listened to the ministers' readings, and when they read the process of the Sima family gaining the world, they felt embarrassed, and directly climbed their faces to the bed, eager to find a crack in the ground to drill into, and said, "So Jin Zuo is safe for a long time"? Even the illiterate Shi Le, who was illiterate, looked down on the Sima family. By the time the Tang Dynasty was repairing the Book of Jin, Li Shimin, who had killed his brother and forced his father to seize the throne, could not bear to look at it, and personally went down to the black court, drawing a conclusion to Sima Yi's biography.
