The demise of Cao Wei can be said to have started with Sima Yi and Cao Shuang's joint auxiliary government, which was not originally the auxiliary political combination that Cao Rui really prepared, but was temporarily determined after a series of things, so it inevitably had natural defects.

For Cao Shuang and Sima Yi, Cao Rui himself was a little worried about Cao Shuang earlier, and made some arrangements, for Sima Yi, Cao Rui himself was not unscrupulous.

【Cao Shuang and Sima Yi】

During Cao Rui's reign, it is an indisputable fact that he himself trusted Sima Yi, the Taiwei, but this does not mean that Cao Rui is unwary of Sima Yi. At that time, Sima Yi was already the Tai Lieutenant among the Three Dukes, and was actually the highest military commander of Cao Wei, since the founding of Cao Wei, this is something that only the Cao clan such as Xiahou Xuan, Cao Ren, Cao Xiu and Cao Zhen have done (Originally, Cao Wei's highest military commander position should be Da Sima, but no one held this position in the later period, so Sima Yi was promoted from general to Tai Lieutenant, which was actually the highest military commander).

According to the record of "Shiyu", the emperor was worried about Sheji and asked Jiao (Chen Jiao): "Sima Gong is loyal and upright, can he be described as the minister of Sheji?" Jiao said: "The hope of the imperial court; Sheji, unknown also. ”

In the later period of Cao Rui's reign, it can be said that Sima Yi has already made great achievements, which is why Cao Rui chose the auxiliary minister at the beginning, but did not choose Sima Yi, the only remaining of the four auxiliary ministers left by Cao Pi.

Sima Yi was able to become an auxiliary minister in the end, thanks to Liu Fang and Sun Zi, if it wasn't for the two of them fighting for power with Cao Yu and others, Cao Shuang could only be pushed up in the end, and Cao Shuang alone could not take on such a heavy responsibility, at least one more important person must be added, otherwise how could there be a matter of Sima Yi.

And what about Cao Shuang? I have to say that although Cao Shuang was a great success in the end, he not only retained the status of the auxiliary minister, but also went further, but this status was obtained by betrayal in a sense, whether active or passive, Cao Shuang betrayed Cao Yu and others to have this status, otherwise the position of the general has nothing to do with Cao Shuang.

Cao Rui himself was not very relieved about Cao Shuang, so he asked Cao Shuang to accept the edict at the bedside, appointed Sun Li as the general Changshi, and awarded the free cavalry permanent attendant. Sun Li is honest and upright, and is an excellent candidate for assistance, but Cao Shuang thinks that Sun Li is unfavorable to him, so he sent Sun Li out after Cao Rui's death, and later reused He Yan, Bi Rail, Deng Yang, Li Sheng, Ding Mi and others who were suppressed by Cao Rui because of their vanity and untruthfulness.

Although Cao Shuang is the queen of the clan, to be honest, his qualifications are too shallow, and he is too young, and there is no comparison with the Taiwei Sima Yi from the beginning, if these two people jointly assist the government, it may not be a problem if Cao Shuang is good, after all, there is a clan behind Cao Shuang, and there is righteousness, even if Sima Yi has the heart, he may not be able to shake Cao Wei, not to mention that Sima Yi may not have this intention at the beginning.

But if Cao Shuang is evil, it will be a big problem, as the actual spokesperson of the Cao family, if he does evil, it will not only have a very bad impact on himself, but also have a very bad reaction to the entire Cao clan, which will directly shake the foundation of Cao Wei's society. The tragedy is that Cao Shuang was killed by Sima Yi as a villain in history, and Sima Yi killed not only Cao Shuang, but also the entire Cao clan that time.

Although in history Sun Ce entrusted Sun Quan to Zhang Zhao, and Liu Bei used Zhuge Liang and Li Yan as Liu Chan's auxiliary ministers, it must be understood that the situation in Jiangdong and Shu Han at that time was completely different from the situation at this time for Cao Rui. At that time, Jiangdong and Shu Han were facing an existential crisis, and the external pressure was much higher than the internal, and Cao Wei did not have a big external threat at that time, so it was more important to pay attention to internal problems, and it was very inappropriate to leave only two auxiliary ministers at this time, just like Cao Pi left four auxiliary ministers to Cao Rui back then, and Sima Yi and Chen Qun, who were surnamed Sima Yi and Chen Qun, had never led troops to fight, and Cao Xiu and Cao Zhen of their own clan were both veteran generals.

At this time, Sima Yi is a veteran commander, Cao Wei is actually the highest military commander, known for his military exploits, compared to Cao Shuang is a little fresh, the foreign surname has not only suppressed the relatives, but also the foreign surname is easy to hold together, which is terrible.

[Previous Candidates]

In contrast, Cao Rui excluded Sima Yi earlier, and the candidates for auxiliary ministers headed by Cao Yu, the king of Yan, supplemented by Xiahou Xian, Cao Zhao, Cao Shuang, and Qin Lang, were much more reliable. First of all, there is no Sima Yi in this candidate, which is an obvious suppression. After Sima Yi pacified Liaodong, the prestige of the Sima family has reached a new height, and it has begun to pose a threat to the clan, so Cao Rui can no longer be indifferent, before Cao Rui's death, in a sense, others can be auxiliary ministers, but Sima Yi cannot.

And led by Cao Yu, the king of Yan, it seems that the vassal king is in power, and there are endless troubles, but after all, Cao Fang is not Cao Rui's own son, and he is adopted, so this matter is relatively not very important at this time. What's more, although Cao Yu is Cao Cao's son, he lacks a foundation, and it is not so easy to usurp power, and Cao Fang is young, so it is best to control the power in the hands of the clan.

Among the five people selected by Cao Yu and others, only Qin Lang can only be said to be barely a foreign surname, after all, Qin Lang is Cao Cao's stepson, and he himself has no blood relationship with Cao Cao, but his mother, Mrs. Du, is married to his wife Cao. Therefore, Cao Rui's earlier selection of auxiliary ministers could be the first to ensure the absolute superiority of the clan.

However, it can also be seen from this candidate that the Cao clan has begun to decline, and the decline of Cao Wei is inevitable. Cao Wei, Cao Wei, the backbone of Wei is the Cao family, and Shu Han and Sun Wu are different, the core figures of Cao Wei have always been dominated by the Cao family and the Xiahou clan, and the two southern kingdoms have been the core of generals and ministers with foreign surnames since the Sun Ce and Liu Bei periods, so Shu Han and Sun Wu only need to control the imperial power in their hands, and Cao Wei also needs the clan to come forward to control the overall situation, Cao Pi had Xiahoudun at the beginning of his power, and Cao Rui had Cao Xiu and Cao Zhen at the beginning of his power, so Cao Rui had to leave Cao Yu, Cao Shuang and others to Cao Fang before he died.

But can Cao Yu, Cao Shuang and others compare with his ancestors, Xiahoudun, Cao Ren, Cao Zhen and others, who have been generals, are not unknown, they all have military exploits and political achievements earlier, and their qualifications are all there, and Cao Yu, Cao Shuang and others have nothing but blood, to be honest, why should they be auxiliary ministers. The reason why Cao Wei began to implement the nine-product Zhongzheng system in history is also closely related to the Cao family's practices, and if you want to take power at that time, you must first ask: "Is your surname Cao?" Is your surname Xiahou? Oh, neither, just pull aside. ”

Compared with the first-generation clan headed by Xiahoudun and Cao Ren, and the second-generation clan headed by Cao Xiu and Cao Zhen, the third-generation clan headed by Cao Shuang and others is obviously inferior to the first generation, and the quantity and quality of talents are significantly reduced. Even if Cao Yu and others succeeded in taking power in history, it could not change the fact that Cao Wei began to decline, because the practice of the Cao family in power had begun to reach a dead end.

In history, Sima's replacement of Wei's was accidental, but there are also inevitable factors in this.
