Sima Yi, a native of Zhong Da, was born in Wenxian County, Hanoi (now southwest of Wenxian County, Henan Province). He was born into a powerful family with a history of 2,000 stones since the Eastern Han Dynasty, and his father Sima Fang was an official of Jing. Sima Yi was a county official in his early years. In the 13th year of Jian 'an, he was turned into a civil servant by Cao Cao. In the twenty-second year of Jian 'an, Cao Pi became a prince, and Sima Yi was the illegitimate child of the prince. He, together with Chen Qun, Wu Zhi and Zhu Shuo, is the "four friends" of Cao Pi, and he is the main figure of Cao Pi's think tank. In the twenty-fifth year of Jian 'an (220), Cao Pi took the place of Han, and Sima Yi served as the prime minister's office chief and supervisor of the empire. In the seventh year of Huang Chu (226), Cao Rui succeeded to the throne, and General Sima Yi moved to command the imperial army. He also served as a general in title of generals in ancient times, commander-in-chief of military affairs in Jingyu and Yuzhou, sat in Wancheng and presided over Jingzhou's attack on Wu. In the third year of Jing (239), Cao Rui collapsed, Prince Cao Fang succeeded to the throne, and Sima Yi and Cao Shuang assisted. In the first year of Jiaping (249), Sima Yi killed Cao Shuang and his henchmen. Sima Yi died of illness the following year, and his sons Sima Shi and Sima Zhao assisted the government. In 265 AD, his grandson Sima Yan named Wei of the Jin Dynasty "Xuan Di".

After Zhuge Liang's death, Sima got Zhuge Liang's The Art of War and read it happily. But Zhuge Liang had long anticipated Sima's actions and knew that Sima had the habit of flipping through books and licking his fingers, so he painted poison on the art book before he died. The consequences can be imagined.

As for saying that death is only an official answer, will his descendants tell everyone that he was poisoned by the dead?

Just like an empty plan, Sima Ming knew that there was no one inside, and that Zhuge Liang was calculating, but he still had to let him go. The reason is that the rabbit died and the dog was cooked. In the military wars of past dynasties, it is particularly important to know how many troops there are in a city with Sima Jun's ability. We have to admire Sima Shi's humiliation and the unity and wisdom of Sima family. Otherwise, the Sima family will not be able to win the world, if the hero is judged by victory or defeat.
