In the Three Kingdoms, there were many orphans, but in general, most of the orphans were successful, and only Cao Rui was a lonely Sima Yi, which was quite a failure.
First, Sun Ce entrusted the orphan Sun Quan
Sun Ce was the young lord of Jiangdong, he was young, he even destroyed a strong enemy and captured the six counties of Jiangdong, but unfortunately, when he captured Jiangdong, he also made a lot of enemies, and finally when he was hunting, he was shot by the enemy family. Before dying, he needed to find a suitable lord for Jiangdong.
Although Sun Ce was the lord of Jiangdong, around Jiangdong, surrounded by wolves, Cao Cao, Yuan Shao, Liu Biao and other tyrants all looked at Jiangdong and wanted to take it for themselves, so Sun Ce could not give Jiangdong to his young son, otherwise not only could not save Jiangdong, but their family might also suffer the scourge of extinction, so Sun Ce left Jiangdong to his younger brother Sun Quan, and also arranged for Zhang Zhao and Zhou Yu to be responsible for Sun Quan.
"Foreign affairs are not decided to ask Zhou Yu, internal affairs are not decided to ask Zhang Zhao", Zhang Zhao and Zhou Yu are very talented and prestigious, but relatively speaking, it is relatively unsuccessful to be alone with Zhang Zhao, Zhang Zhao is the representative of the Jiangdong family clan, after Cao Cao went south, for the benefit of the Jiangdong Shi clan, he persuaded Sun Quan to surrender to Cao Cao, but Zhou Yu advocated resistance to the end, and also helped Sun Quan defeat Cao Cao in the Battle of Chibi.
After Sun Ce's death, Sun Quan, with the assistance of Zhou Yu and Zhang Zhao, not only saved Jiangdong, but also made Jiangdong stronger, which shows that his trust was very successful.
Second, Liu Beituo isolated Zhuge Liang
Before Liu Bei was forty years old, compared with Cao Cao, Yuan Shao and other tyrants, he could be regarded as accomplished nothing, not even having a foothold of his own, but Liu Bei's ambition was no less than theirs, he had always thought of "KuangFu Han Room", and he finally took Jingzhou, Yizhou and Hanzhong with the help of Zhuge Liang, Pang Tong, Fazheng and others, and Sun Quan and Cao Cao, and had the strength to wrench his wrist with Cao Cao and Sun Quan. Later, after Cao Pi forced Emperor Xian of Han to cede the throne to him, Liu Bei also claimed the title of emperor in Shudi in order to continue the Han Dynasty.
After Liu Bei became emperor, due to a strategic mistake, he launched the Battle of Wu in order to retake Jingzhou and avenge Guan Yu. Unfortunately, the fiasco at Yiling was defeated by Jiangdong, which shattered Liu Bei's dream of "Kuangfu Han Room", and he could not afford to fall ill from then on, and soon died of illness in the White Emperor City.
Before Liu Bei's death, he arranged Zhuge Liang and Li Yan to be his sons Liu Chan's orphan ministers. Subsequently, in the course of infighting, Li Yan lost to Zhuge Liang and was deposed by Liu Chan, and Zhuge Liang achieved monopoly of power. Although Zhuge Liang became a "powerful minister", he was also a virtuous and loyal minister, and during his assistance to Liu Chan, he devoted his life to the governance of state affairs, and he also dedicated his life to the Shu Han Dynasty for Kuang Fu Han and led the Northern Expedition. Zhuge Liang was like a big tree that shielded Liu Chan from the wind and rain, and was a very reliable assistant minister.
Third, Cao Rui entrusted the lone Sima Yi
After Cao Pi's death, He arranged Cao Zhen, Cao Xiu, Chen Qun, and Sima Yi to be the trusted ministers of his son Cao Rui, which allowed Sima Yi to begin to take power, but due to the suppression of Cao Xiu and Cao Zhen, two of Cao Wei's pro-generals, Sima Yi's influence in Cao Wei was weak, and it posed no threat to Cao Wei. With the death of Cao Zhen and Cao Xiu, Cao Rui could only reuse Sima Yi in order to fight against Zhuge Liang, which made Sima Yi's power strong. Even so, since Cao Rui was a very capable emperor, Sima Yi was incapable of usurping his country.
Like his father Cao Pi, Cao Rui was a short-lived monarch who died of illness at the age of 35. Before his death, he arranged Cao Shuang and Sima Yi to be the trusted ministers of his son Cao Fang. Although Cao Fang was an emperor, because he was a child, he became a spectator in the struggle of the court. After Cao Rui's death, Cao Shuang and Sima Yi engaged in a fierce contest. Sima Yi had been in the battlefield for a long time, the city government was extremely deep, the strategists were sophisticated, and Cao Shuang, who was young and immature and had poor talent, was not his opponent at all, but Cao Shuang, with his status as a relative of Cao Wei and the support of other Cao Wei clan relatives, allowed him and Sima Yi to occupy the top for a long time in the contest.
In the struggle with Cao Shuang, Sima Yi chose to retreat into the future, and he took the initiative to show Cao Shuang weakness by pretending to be ill. Through his superb acting skills, Sima Yi deceived Cao Shuang and made him think that Sima Yi was already terminally ill and would soon die, so he relaxed his vigilance against Sima Yi.
Later, Cao Shuang, Cao Fang, and others went to Gaoping Tomb to worship their ancestors, and Sima Yi seized the opportunity to decisively launch a coup d'état and take control of the court. At this time, Cao Shuang still had the emperor Cao Fang in his hands, and he could mobilize the world's soldiers and horses to serve the king in the name of Cao Fang, and let them fight Sima Yi together. Although Cao Shuang may not be able to defeat Sima Yi, he at least has a glimmer of life, but unfortunately, Cao Shuang chose to surrender without a fight.
After surrendering, Cao Shuang and others were killed by Sima Yi, and Cao Fang became Sima Yi's puppet. After this, Emperor Cao Wei, a military general loyal to Cao Wei, constantly rebelled and tried to regain control of Cao Wei's Jiangshan from the Sima family, but was pacified by Sima Yi and his sons Sima Shi and Sima Zhao, and after sima Yan's hands, he deposed Emperor Cao Wei, proclaimed himself emperor, and established the Jin Dynasty. Cao Rui arranged for Sima Yi to be the chancellor of his son Cao Fang, but let Cao Wei lose Jiangshan, which shows that his orphan was extremely unsuccessful.
