According to the Records of the Three Kingdoms, Xun You served as assistant minister of the Yellow Gate during the period when Blade came to power. When Dong Zhuo went to Beijing, he was imprisoned for plotting to assassinate Dong Zhuo, and then abandoned his official position and went home. After Cao Cao welcomed the emperor into Xudu, Xun You became Cao Cao's strategist. When Cao Cao conquered Lyu3 bu4, Xun You dissuaded Cao Cao from withdrawing troops, and offered his ingenious plan to flood Pi City and capture Lyu3 bu4 alive. In the battle of Guandu, Xun You made a diversion and killed Yan Liang and Wen Chou. In addition, he also sent Huang Xu to burn Yuan Shao's grain and grass, and at the same time urged Cao Cao to accept Xu You and draw a map of nesting, which made great contributions. During the period of pacifying Hebei, at once urged Cao Cao to destroy Yuan Shao's philosophers, and Cao Cao was named Hou Ting as the spiritual pivot by the court. Xun You was well thought out and kept a low profile, and was praised by Cao Cao. In the 19th year of Jian 'an (2 14), Xun You died when Cao Cao attacked Wu.
In Romance of the Three Kingdoms, Cao Cao greeted Emperor Xu and worshipped Xun You as his military adviser. Xun You begged Lu Bu to set up Hebei, Guandu and Battle of Red Cliffs, and made many ingenious plans. And establish the state of Wei, with Xun You as minister. Cao Cao was promoted to Wang Wei, and Xun You thought that Cao Cao rebelled against the Han Dynasty. Cao Cao was furious, and Xun You became angry from embarrassment and soon died, just like Yu Xun.
The History of the Three Kingdoms is a history book, and The Romance of the Three Kingdoms is a novel. It's reasonable to believe in the reflection, but the author of the reflection, Chen Shou, is wei ren, which inevitably beautifies Wei, so it's impossible to know whether Xun You's death has anything to do with Cao Cao.
Hope to adopt.
