Jia Xu was a famous strategist at the end of the Eastern Han Dynasty and a hero of the founding of Cao Wei. However, many people do not understand why Jia Xu is called a poisoner, in fact, it is precisely because many of Jia Xu's schemes make people feel that there is no bottom line, in order to achieve the goal can be unscrupulous, so they deducted a title of "poisoner". However, Jia Xu was indeed a very powerful figure at that time, and it can be said that from the complete demise of the Eastern Han Dynasty to the formation of the situation of the Three Kingdoms, it was more or less related to Jia Xu. Jia Xu was originally a subordinate of Dong Zhuo, and after Dong Zhuo's death, he designed to let Li Yu and Guo Feng counterattack Chang'an, although the plan failed, but the regime of the Eastern Han Dynasty had fallen apart and declared complete death. After that, Jia Xu transferred to Cao Cao's command, helping Cao Cao unify the north in one fell swoop, and suggesting that Cao Cao should not abolish Chang Liyou and secretly assist Cao Pi in ascending the throne. It can be seen that the importance of Jia Xu to Cao Wei is still irreplaceable. Then this time I will tell you about the more important strategies in Jia Xu's life, and as for whether it is poisonous or not, it will be left to you to judge for yourself.
After Dong Zhuo moved into Chang'an, Jia Xu served as a lieutenant in Dong Zhuo's army, which was a period of beautiful life. However, after Dong Zhuo's death, Wang Yun began to purge Dong Zhuo's Yu Party, which had the opportunity to let Han Tianzi regain power. However, Jia Xu encouraged Li Yu and Guo Feng to kill them back to Chang'an, and instead of sitting still, it was better to take life and death into their own hands. As a result, Wang Yun and others were killed, Chang'an fell into chaos again, not to mention, the world was even more chaotic, everywhere was divided by the masses, and the people did not have a good life. It is precisely because of this plan that Jia Xu was scolded as a poisoner.
After that, Jia Xu chose to switch to Zhang Xiu's account for a short period of time, during which Jia Xu also helped Zhang Xiu to defeat Cao Cao with the strategy of defeating the soldiers. However, on the eve of the Battle of Guandu, Yuan Shao and Cao Cao began to woo Zhang Xiu, and this choice was very important for Zhang Xiu. Zhang Xiu wanted to defect to Yuan Shao, but Jia Xu chose Cao Cao, and Zhang Xiu feared that he and Cao Cao had a vendetta against him. However, Jia Xu listed Cao Cao's advantages, although Yuan Shao had many people but his heart was uneven, Cao Cao was the one with great talent and strategy, and finally proved that Jia Xu's choice was right.
After Cao Cao unified the north, he prepared to go south to take over Jingzhou, but the Battle of Chibi was defeated and could only temporarily retreat to the north. In fact, one of the reasons why Cao Cao would fail was because the combined forces of Ma Chao and Han Sui in the rear made him very jealous. If he was trapped in Jingzhou, he was afraid of a fire in the backyard, so Cao Cao was eager to take Jingzhou. This time, he came back to take the Guanzhong coalition army to open the knife first, at this time Jia Xu offered advice to provoke the relationship between Ma Chao and Han Sui, and successfully made Ma Chao suspicious of Han Sui. In the end, Cao Cao defeated the coalition forces in one fell swoop and pacified Guanzhong.
In fact, Jia Xu's influence on the Cao family was not limited to official affairs, but even affected Cao Cao's lichu incident. Cao Pi and Cao Zhi were both the most favorable candidates for the heir, but Cao Cao favored Cao Zhi more, and jia Shi took Yuan Shao and Liu Biao as examples, suggesting that Cao Cao should not abolish Chang Liyou, secretly helped Cao Pi become an heir, and finally succeeded in ascending the throne as emperor. Although Jia Xu's reputation is not very good, he is also one of the few big people who can achieve a good death in the chaotic world.
