According to the standards of the hereditary system of kings in ancient times. First of all, we must establish a successor. Liyan is the son of the wife, and he is called Liyan.

Then Cao Zhi and Cao Pi both meet the criteria for establishing a successor. In the end, Cao Pi finally won the position of crown prince with the help of Wu Zhen and the guidance of Jia Xu.

became the successor of the Cao Wei regime. In the end, Cao Gong finally decided to make Cao Pi the crown prince. At that time, whether the heir of Cao Gong should be Cao Pi or his younger brother Cao Zhi should be established, all factions in the court had their own opinions.

Later, after Cao Gong's careful thinking, coupled with the persuasion of the ministers. Jia Xu said: "Cultivate morality and be diligent in learning. Day and night. Do not violate the morality of being a son. It is enough to do so. At that time, whether the heir of Cao Gong should be Cao Pi or his younger brother Cao Zhi should be established, all factions in the court had their own opinions.

The ancients also had a principle, that is, to grow up. As the eldest son, Cao Pi was born to Mrs. Bian, Cao Cheng's wife.

And Cao Pi is still a son-in-law. Therefore, Cao Pi's status is very high. No matter what. It is impossible for Cao Zhang to inherit the throne of Duke Cao.

In the end, Cao Gong finally decided to make Cao Pi the crown prince. First of all, one thing should be clarified. Cao Zhang, Cao Pi and Cao Zhi were all three sons born to Cao Gong's wife, Madame Bian.

Cao Zhi also has his own think tank in the process of competing for the throne this time (Cao Pi also has it). Cao Pi is different.

Cao Pi is smarter in front of Cao Gong. In fact, Cao Pi was very worried that the Cao Guild would choose Cao Zhi as the crown prince, and he was often frightened.

After a period of observation. Cao Gong had an ironclad principle for choosing an heir. In the eyes of Cao Gong, Cao Zhi is more important.

After a period of observation. Cao Gong had an ironclad principle for choosing an heir. In this case, Cao Zhi and Cao Pi are both candidates for succession.

So who to choose? The ancients also had a principle, that is, to grow up. Then the only ones left are Cao Zhi and Cao Pi.

So why, Cao Pi was made the crown prince? The fourth reason is that there are high-level people. Personally, I think Cao Zhi is very talented.

is even higher than Cao Zhi's elder brother Cao Pi. However, under the principle of standing and growing, Cao Zhi has little chance of winning as the heir.

Later, after Cao Gong's careful thinking, coupled with the persuasion of the ministers. Because at this time, Cao Gong's age was not young.

In the end, Cao Pi finally won the position of crown prince with the help of Wu Zhen and the guidance of Jia Xu. became the successor of the Cao Wei regime.

First of all, one thing should be clarified. Cao Zhang, Cao Pi and Cao Zhi were all three sons born to Cao Gong's wife, Madame Bian.

And Cao Gong said that he was willing to listen. Jia Xu said: "I think of Yuan Shao, when Liu Biao and the two of them were heirs. Later, after Cao Gong's careful thinking, coupled with the persuasion of the ministers.

Cao Zhi mainly has three people, one is named Ding Yi. The second person is called Ding Yi, and the third person is called Yang Xiu. They are Cao Zhang, Cao Pi and Cao Zhi.

And it can help Cao Pi the most. And the most important person is Jia Xu. And there is a person named Wu Zhen on Cao Pi's side.

So how did Wu Zhen help Cao Pi? As a result, Cao Gong liked Cao Pi more and more. I don't like Cao Zhi more and more.

After a period of observation. Cao Gong had an ironclad principle for choosing an heir. Later, Cao Pi and Cao Zhi were completely different.

Cao Zhi does not pay attention to his own behavior. And Cao Pi is very smart and good at mental skills. And clamp the tail and be a man.

There is another reason why Cao Zhi cannot be the heir. That is, Cao Zhi is very capricious. Do whatever you want in terms of behavior.

And he doesn't check himself. In addition to Jia Xu speaking for Cao Pi, there are also Wu Zhen and Huan Jie, who speak for Cao Pi.

Cao Zhi mainly has three people, one is named Ding Yi. The second person is called Ding Yi, and the third person is called Yang Xiu. Why Cao Zhang?

The author believes that Cao Zhang is just a military general. There are too many things to do in governing the country. Standing is meant to be among the candidates for succession to the throne.

The eldest son-in-law. for the heirs. Then Cao Pi is older than Cao Zhi. Cao Pi may be chosen by Cao Cao.
