The early period of Cao Wei was 191-208 AD. This period of time was from Cao Cao becoming the Taishou of Dongjun to the eve of the Battle of Chibi, including the initial period and rapid development period of the development of Cao Wei Group.

But the gap between them is obvious, Xun Yu's status and influence in the Cao Wei Group can be compared with Xun You, Guo Jia, Jia Xu, and Cheng Yu combined. In addition, Jia Xu succumbed to a disadvantage because of his short time and low contribution, and the gap between Guo Jia and other strategists was also obvious.

【Xun Yu】

Xun Yu's status and influence in the Cao Cao Group are beyond the reach of others, as Cao Cao's second-in-command, his ability is also extremely outstanding, not only all but also fine, even if it is a strategy, no one in the Cao Cao Group can overpower Xun Yu at that time.

Xun Yu and Chen Gong were the first to follow Cao Cao's strategists, Xun Yu was evaluated as Wang Zuozhicai by Nanyang celebrity He Hao, after he took refuge in Cao Cao, he was considered by Cao Cao to be his own ovary, but in fact Xun Yu is not only Cao Cao's Zhang Liang, but also Cao Cao's Xiao He.

During the battle of Cao Lu Yanzhou, Xun Yu stayed in the rear, and it was he who first discovered Lu Bu's invasion plot, and made a counterattack, and later entered the camp of Yuzhou Assassin Shi Guogong, forcing back tens of thousands of troops under his command. After Tao Qian's death, Cao Cao was ready to give up Lü Bu first and seize Liu Bei's Xuzhou, but it was Xun Yu who persuaded Cao Cao, thus not giving Lü Bu a chance to turn the tables.

At that time, most of Cao Cao's subordinates did not recommend Cao Cao to welcome the Son of Heaven, thinking that the situation at that time did not allow it, and it was Xun Yu who overrode the public opinion to let Cao Cao welcome the Son of Heaven and seek the name of righteousness, and then Cao Cao got the emperor, and the power developed rapidly.

More importantly, Xun Yu also recommended many talents for Cao Cao in history, including Xun You, Zhong Xuan, Guo Jia, Xi Zhicai, Chen Qun, Du Qi, Sima Yi and others. But among them, there are also Yan Xiang and Wei Kang who failed.

Xun Yu is more excellent is his comprehensive view of the overall situation, of which "four wins and four defeats" is only one of them, and then Cao Cao was ready to withdraw at the critical moment of the Guandu confrontation, leading the enemy deeper, it was Xun Yu who wrote a letter from Xuchang to dissuade Cao Cao, and then Xun Yu was the first to stand up on the issue of first south and first north to Cao Cao to pacify the north, Cao Cao pacified the north and prepared to crusade against Jingzhou Liu Biao, and Xun Yu also offered advice to Cao Cao, and Cao Cao easily got Jingzhou.

The most rare thing is that Xun Yu himself is an outstanding talent who can stand alone, and his political talent is also the top at that time, in the more than 20 years that Xun Yu managed the rear for Cao Cao, there have been basically no major problems, it can be said that with Xun Yu, Cao Cao does not need to worry about his belly, especially the battle of Yanzhou with Lu Bu back then, without Xun Yu, Cao Cao's fate may be the same as Liu Bei's result in Xuzhou.

Unlike Guo Jia, there is no Xun Yu in history, and Cao Cao is not Cao Cao. So don't say that only in the early period of Cao Wei, even in Cao Wei and even in the entire Three Kingdoms era, Xun Yu is undoubtedly a first-class character. Few people dared to say that they had overpowered him.

【Xun Yu】

Xun Yu was Xun Yu's nephew, and after Xun Yu, he became Cao Cao's mastermind, and he was second only to his uncle Xun Yu in the ranking of the five great strategists in the early Cao Wei period. Xun You, like his uncle Xun Yu, is also a very scary guy. As early as when he was young, Xun You was already very smart, and even saw through the murder, and later participated in the assassination of Dong Zhuo by Zheng Tai, He Hao and others. After Cao Cao moved the capital to Xuchang, because Xun Yu wanted to sit in the rear, he recommended Xun Yu to replace him.

After Xun You returned to Cao Cao, he lived up to his expectations and was full of scheming, and all of them were proved to be completely correct. Xun You's first plan was to delay the army when Cao Cao crusaded against Zhang Xiu, but unfortunately Cao Cao didn't listen, and later Cao Cao returned in vain under the joint efforts of Zhang Xiu and Liu Biao, and after Cao Cao did not target Zhang Xiu, Zhang Xiu instead took refuge in Cao Cao at Jia Xu's suggestion, which proved the correctness of Xun You's original proposal.

When he was crusading against Lü Bu in Xuzhou, Cao Cao was unable to conquer for a long time and was ready to retreat, but it was Xun You and Guo Jia who dissuaded Cao Cao in time.

Xun You's most glorious time was when Cao Cao and Yuan Shao fought a decisive battle. Xun You first proposed a plan for Cao Cao to attack the east and the west, and divided his troops to lure the enemy, so that Cao Cao eliminated Yan Liang in the Battle of White Horse in one fell swoop; Later, he used the grain transportation team as a bait to successfully eliminate Wen Chou; After that, Xun You persuaded Cao Cao to attack Yuan Shao's grain and grass and break Han Xun; After Xu You came to vote, it was Xun You and Jia Xu who persuaded Cao Cao to believe that he sent troops to fight against Wuchao; Later, the surrender of Zhang He and Gao Ran was even more advocated by Xun You.

In the decisive battle between Cao Cao and Yuan Shao that was related to the fate of the world, Xun You said that his credit was second, and no one dared to say that it was the first.

Later, Cao Cao won the battle against Yuan Shao and the Yuan brothers, and was ready to turn to Liu Biao in Jingzhou, which coincided with Yuan Tan sending Xin Bi to ask for help, Cao Cao originally wanted to go south, but it was Xun You and Xin Bi who finally said that Cao Cao was moved, and Cao Cao then waved his army north, and finally succeeded in defeating the Yuan brothers and getting the four northern states.

In the twelfth year of Jian'an (207), Cao Cao talked about the reward of meritorious deeds, saying: "Being loyal and upright and good at plotting, it is Wen Ruo (Xun Yu) who appeases people inside and outside for me, and Gongda (Xun Yu) is inferior to him." "Increase the number of four hundred, and the first seven hundred, Xun You turned into a Chinese army division.

In the early stage of Cao Wei, it was said that Xun You was the second person under Cao Cao's advisors, and there was no problem.

【Guo Jia】

Guo Jia's reputation in contemporary times has been greatly enhanced, and he is even considered by many people to be above Zhuge Liang, especially for his "Ten Victories and Ten Defeats", anticipating Sun Ce's death, pacifying the north, and crusading against Wuheng.

But in fact, Guo Jia's "Ten Wins and Ten Defeats" is a copy of Xun Yu's "Four Wins and Four Defeats", and the authenticity is doubtful, and it may have been added by Fu Xuan privately. Guo Jia expected that Sun Ce's death was indeed a bit of a clever calculation, but it did not mean much to Cao Cao.

When Cao Cao pacified the north, Guo Jia was indeed very active and important, but this does not mean that Guo Jia contributed much to the pacification of the north, but the fact is the opposite. Cao Cao's crusade against Wuheng was also advocated by Guo Jia, but in fact, Guo Jia's contribution to it was limited, and his strategy may even backfire, Tian Chou was the key person in Cao Cao's victory over Wuheng.

On the whole, Guo Jia was ranked at the bottom of the five major strategists in the early stage of Cao Wei and Jia Xu, he was the only one of the five who failed to prove himself, as one of Cao Cao's core strategists, Guo Jia's contribution to Cao Wei was really limited.

At the same time, Guo Jia is also the only man among the five strategists who cannot be rated as a top strategist.
