Why didn't Sima Yi become an official?

Sima Yi was born in a noble family and was smart and studious since childhood. However, he has a high-spirited personality. He didn't worry about food and clothing, and he was a little disgusted with Cao Cao's behavior of "holding the emperor to make the princes", so he didn't promise Cao Cao immediately.

Sima Yi's name is Zhong Da, and he received a good education since he was a child. He often contacts with some government officials and often listens to them talk about state affairs. He had his own unique views on the country's political and military situation and the situation at that time, and people who came to his house appreciated Sima Yi.

Sima Yi's reputation soon spread to Cao Cao's ears, thinking that there are such outstanding young people, they must be accepted as subordinates and let him work for my Cao family. So Cao Cao wrote a recruitment letter and sent someone to Sima Yi.

Sima Yi immediately wrote back to Cao Cao, pretending: I have no martial arts, no talent, and I can't do anything great. I'm not cut out to be an official. I'd better read and write at home and live a carefree life. By the way, I praised Cao Cao's great talent in my letter and felt honored for Cao Cao's employment. At the end of the letter, he also said that he had leprosy recently and rejected Cao Cao.

Cao Cao was angry at Sima Yi's refusal. Originally, if Sima Yi agreed at once, perhaps Cao Cao did not necessarily attach importance to him. But this refusal caught Cao Cao's attention and he decided to invite Sima Yi.

In other words, Sima Yi also expected that Cao Cao wouldn't give up and would send someone to find out, so he often pretended to be sick. The people Cao Cao sent to investigate are also very cunning. The man came to the detective Sima Yi at night and found Sima Yi lying in bed like a leper, but he was not sure yet, so he stabbed Sima Yi with a knife.

But the cunning Sima Yi also knew that Cao Cao loved talents and would not kill people easily, so he persisted. Seeing that Sima Yi didn't dodge, the man thought that he was really ill, so he went back and told Cao Cao truthfully.

Book of Jin: You can't live because of the wind. Wei Wu had it stabbed at night, but the emperor still didn't move.

Sima Yi thus escaped Cao Cao's first move. In the thirteenth year of Jian 'an, Cao Cao, who became prime minister, decided to use Sima Yi. This time, Cao Cao sent Cao Hong and told him, "If he wants to come, treat him with courtesy, if not, arrest him." Sima Yi heard that Cao Hong was stubborn and didn't dare to pretend to be ill, so he had to go out and follow Cao Hong to find Cao Cao.

Wei Lue: Xuan Di was eager to learn, but Cao Hong was unwilling to help the emperor, and the emperor was embarrassed to visit him, so he invited a sick stick. Hong hated it, and said to Mao, Mao turned the emperor over, but threw a stick and obeyed his orders.
