Today's Three Kingdoms idiom story can be found in the Romance of the Three Kingdoms? Xun You Biography" is in the third year of Emperor Jian'an (198 AD), and the protagonist is Xun You. The original text is as follows:
At the age of the year, Taizu marched from Lü Bu to Xia Pi, Bu defeated and retreated, attacked unabated, continuous warfare, soldier fatigue, Taizu wanted to return. You and Guo Jia said: "Lü Bu is brave and unscrupulous, and now the three wars are all in the north, and his sharpness is weakened." The three armies are dominated by generals, and if the main army declines, the army has no intention. Fu Chen Palace has wisdom and late, now and bu qi has not yet recovered, the palace plot is undecided, attacking urgently, bu ke pull also. "It is the city of Yi and Si, the city of Collapse, and the cloth of raw poultry."
The gist of this record is that in this year, Cao Cao sent troops from Wancheng to attack Lü Bu, who was occupying Xuzhou. When the army advanced to the vicinity of Xia Pi, a fierce battle broke out with Lü Bu, who was defeated and had to retreat into the city to hold firm. Cao's army continued to attack the city, but it could not be attacked for a long time, and the generals were very tired, and Cao Cao planned to withdraw his army and return to Wancheng.
Xun You, together with Guo Jia, said to Cao Cao: "Although Lü Bu is brave and fierce, he has no wisdom. Now that he has lost three consecutive battles with our army, his sharpness has been exhausted. The army's combat is gradually the core, the main general's morale declines, and the subordinates are even less demoralized. Lü Bu's adviser Chen Gong, although intelligent, was slow to act. Now, taking advantage of the fact that Lü Bu's morale had not yet been restored, and Chen Gong had not yet come up with a good strategy, if our army stepped up its attack, it would certainly be able to achieve victory. Cao Cao followed Xun You's advice and poured Yishui and Surabaya water into Xia Pi City, the city walls collapsed, and a large army invaded the city and captured Lü Bu alive.
The Three Kingdoms idiom introduced in this article is "brave and unskillful" in Xun You's mouth, which means that although brave, there is no wisdom. This is also an idiom pioneered by Xun You.
What is Lü Bu's fatal weakness, many people think that it is cunning and repetitive, in fact, this is only half right. In the complicated situation at the end of the Han Dynasty, Lü Bu was not the only one who was cunning and repetitive. Lü Bu had successively turned to Ding Yuan, Dong Zhuo, and Wang Yun in his lifetime, adding up to only three people, and the corresponding Liu Bei had more people, such as Gongsun Zhan, Tao Qian, Yuan Shao, Lü Bu, Cao Cao, and so on. Why Liu Bei was able to succeed in the end but Lü Bu ended up in a different place, Xun You's words came to the point, Lü Bu had no wisdom, that is, no brains.
What is the key to Lü Bu's failure? It is because there is no wisdom and slow response. I think that when he first occupied Xuzhou, if he could submit to Cao Cao and dedicate Xuzhou to Cao Cao, he would not only be able to save his life, but perhaps also become the number one fierce general under Cao Cao. The result was that Lü Bu and Cao Cao became enemies and eventually vanished.
