Friends who like the Three Kingdoms know that Cao Cao is a hero of a generation. Cao Cao eliminated a large number of warlords and made great contributions to the time.

Cao Cao has many advisers, such as Guo Jia , Guo Jia, Xun Yu , Jia Xu , Xun You , Cheng Yu , etc. However, Cao Cao's most respected adviser should be Guo Jia.
Guo Jia is like Xiang Yu 's Fan Zeng . He has made great contributions to Cao Cao. Without Guo Jia's help, it would be difficult for Cao Cao to defeat Yuan Shao, and he would not be able to unify the north, and it would be difficult for Cao Cao to develop so quickly.

At the end of the Eastern Han Dynasty, the world was in chaos, warlords were separatist, and the people were living in poverty. Cao Cao wrote a poem "White bones are exposed in the wild, and there is no rooster crowing for thousands of miles." The vivid description of the situation at that time.
When Guo Jia was young, he had lofty ambitions and liked to make friends with heroes. At that time, Yuan Shao was in power in the north and Yuan Shao was the most powerful, so Guo Jia went to surrender to Yuan Shao.
After Guo Jia defected to Yuan Shao, he found that Yuan Shao was not good. Guo Jia said that Yuan Shao "has been thinking too much but lacks the key points, likes planning but has no decisions, and wants to work with him to save the country's danger and build a great cause of becoming king and dominate the world, so Guo Jia left Yuan Shao and traveled around the world.
Cao Cao thought that his subordinates were not enough, so he asked Xun Yu to recommend his adviser, and Xun Yu recommended his friend Guo Jia to Cao Cao.

After Guo Jia defected to Cao Cao, the two had a good chat. Cao Cao said, "The person who can help me achieve great things is him." Guo Jia saw that Cao Cao loved talents and was very sincere. Guo Jia said, "This is my real master."
Everyone knows that Cao Cao is lustful, and Guo Jia is also very lustful. Because Guo Jia is too lustful and spends time drinking and drinking all day, many people reported to Cao Cao and fired Guo Jia. Cao Cao said that he is a talent, so let him play.

Let’s take a look at Guo Jia’s contribution. Guo Jia’s contribution is mainly to help Cao Cao defeat Yuan Shao, pacify the north, and greatly increase Cao Cao’s power.
Guo Jia also helped Cao Cao defeat Lu Bu . Cao Cao attacked Lu Bu, but could not defeat him for a long time. Cao Cao gave up. Guo Jia said: "If a brave but not a planner is weak and exhausted, he will soon be defeated." Cao Cao followed Guo Jia's plan, attacked Lu Bu fiercely, and finally defeated Lu Bu.
Guo Jia's contribution also saved Liu Bei , Lu Bu defeated Liu Bei, Liu Bei had no choice but to surrender to Cao Cao. The adviser Cheng Yu suggested to Cao Cao to kill Liu Bei. Cao Cao asked Guo Jia, and Guo Jia believed that Liu Bei was defeated and he should not be killed, otherwise the others would be in a hurry to move forward. How could Cao Cao find talents? After hearing Guo Jia's words, Cao Cao did not kill Liu Bei.

Yuan Shu When Yuan Shao from Beitou, Liu Bei saw that Guo Jia and Cheng Yu were not by Cao Cao's side. Liu Bei took the initiative to ask Cao Cao for him to attack Yuan Shu. Cao Cao agreed, and Liu Bei successfully left Cao Cao.
Everyone knows that Zhuge Liang When he came out of the mountain, Guo Jia was already dead. If Guo Jia had not died and Zhuge Liang met Guo Jia, what would happen to the history of the Three Kingdoms?
After Zhuge Liang came out of the mountain, he defeated Cao Cao through the heroes' meeting, through the power of Dongwu , and through the battle of Red Cliffs . Zhuge Liang took advantage of the tricks and obtained Jingzhou .

Zhuge Liang took advantage of Cao Cao's defeat and his strength was greatly reduced. Zhuge Liang entered the weak Liu Zhang , and Zhuge Liang got Yizhou again.
Whether in Jingzhou or Yizhou, Zhuge Liang used tricks and no big war broke out. Cao Cao, whether he fought Yuan Shao, Lu Bu and Yuan Shu, was a big battle.
Zhuge Liang went out of Qishan six times and returned in vain. General Wei Yan was not convinced. Wei Yan said that if he asked him to lead his troops, he would take Chang'an early. Many military experts believe that Zhuge Liang will not lead troops and do not know how to attack him. If Wei Yan said, Zhuge Liang would probably have won a long time ago.
What will happen if Guo Jia meets Zhuge Liang? After Cao Cao was defeated in Red Cliff, Cao Cao said: "If Guo Jia is here, he will not be defeated." Cao Cao is right. Guo Jia is a genius, and Cao Cao listens to Guo Jia's plans very much. Guo Jia will not be unable to see the plans of Zhou Yu and Zhuge Liang.
If Cao Cao wins the Battle of Chibi, Liu Bei will have nothing to worry about. Jingzhou must belong to Cao Cao, and Yizhou may also belong to Cao Cao. Liu Bei can only seek refuge with Sun Quan and Cao Cao.
Liu Bei had no choice but to seek refuge with Cao Cao. If Guo Jia had not died and there was no need to find a reason, he would have definitely killed Liu Bei and Zhuge Liang.

Sun Quan is also too difficult. Without Wu and Shu to jointly check and balance Cao Cao, it would be difficult for Sun Quan to fight against Cao Cao. Although Sun Quan would not be defeated, it would be more difficult.
The film and television drama "The Romance of the Three Kingdoms" deified Zhuge Liang. In fact, Zhuge Liang was not that good. In terms of strategy, he could not compare with Guo Jia, and in terms of literature, he could not compare with Cao Cao.
History should be respected. Zhuge Liang made a great contribution to Liu Bei. In terms of strategy, who is more powerful, Guo Jia or Zhuge Liang? Is Zhuge Liang stronger than Guo Jia?
