I would like to mention the name cao xiu, everyone should not be unfamiliar, although it is not more famous than Guan Yu Lübu and others in the Three Kingdoms period, but in that era can also be regarded as a legendary figure.
At that time, the world was in chaos, and the major families returned to their hometowns. Cao Xiu lost his father in his early teens, and he temporarily buried him with a guest, and later he took his mother and crossed the river to Wu County. At that time, Taizu was fighting, Cao Xiu all the way to hide his name, all the way bumpy, just to see Taizu, kung fu did not pay off, and finally he was able to meet Taizu as he wished. Taizu treated him even more dearly than his own sons, and was very fond of him.

Cao Xiu often accompanied Taizu everywhere to conquest, and Taizu let him grasp the power of the military department. At that time, Liu Bei sent a general to garrison Xiafang, and Taizu sent Cao Hong to conquest, making him a general and participating in a major battle. Taizu said to Cao Xiu, "Although you are only allowed to participate in this battle, remember that your position is that of a great general." Cao Hong listened to this and let him do it, without any objection. Liu Bei sent Zhang Fei to garrison Gushan and tried his best to cut off Cao Xiu's rear road. Cao Xiu's men began to be in chaos at this time, and the people in the military camp were even more panicked.
Cao Xiu said: "If Liu Bei's army wants to cut off our rear road, then they will definitely arrange ambushes to attack us." Before the action had even begun, they had already released such a sentence, which only proved that it was a smoke bomb, and they must have arranged it else. We should send troops at this time, attack them first, and catch them off guard, so that the enemy will also retreat. Cao Hong listened to Cao Xiu's advice and immediately led his troops to attack Zhang Fei, and sure enough, Zhang Fei's troops were scattered before they could react, and everyone discarded their armor and fled into the wilderness.
After this, Cao Xiu's status rose sharply, and after Xiahou Huan's death, he officially grasped the power of the military department, and after this, he led the Wei forces to win large and small battles.
Emperor Wen personally enlisted Sun Quan, appointed Cao Xiu as a general, and led Zhang Liao and others to march toward Sun Quan. At Topo, he attacked Sun Quan's general and his army. Cao Xiu gradually began to gain a certain position in the State of Wu. At that time, there was a general of Eastern Wu stationed in Anhui City, who was unremitting in Cao Xiu's ability and very much wanted to challenge Cao Xiu. As a result, Cao Xiu launched a fierce attack on him, and finally killed him, and his generals surrendered to Cao Xiu with some remnants. Cao Xiu's promotion to the rank of Grand Sima in the State of Wei can be said to be a position above ten thousand people under one person.
Once, Eastern Wu's army surrendered, and Cao Xiu led his troops deep into Eastern Wu's territory, and the form at that time was very unfavorable to Cao Xiu, and Cao Xiu had to retreat to Shiting with his troops. In the middle of the night, there were some noises in the barracks, and the soldiers began to panic and began to flee in all directions, and some of the equipment was left in place. After that, he asked the emperor for his guilt. Instead of blaming him, the Emperor comforted him and told him not to feel too guilty, and he also awarded him the highest courtesy and a large reward of the highest rank, which shows how favored he was in the Emperor's place. Cao Xiu was wounded in this battle, and in the days that followed, the wound became infected, resulting in Cao Xiu's death.
In that era of war and strife, there were many heroes and good men, and the popular Guan Yu, Lü Bu and others have been passed down to this day. But there are many heroes like Cao Xiu, who are not known to many people. We should evaluate history from an objective point of view.
