Guan Yu and Zhang Fei are both called "ten thousand enemies" in the main history, not only are they strong in martial arts, but also brave and good at fighting, they can stand alone, for example, Guan Yu zhen shou Jingzhou, Zhang Fei zhen shou Lang zhong. Even Zhou Yu once praised Guan Yu and Zhang Fei as "the generals of the bear and tiger", which is not good, which shows the fierceness of Guan Yu and Zhang Fei.
Guan Yu and Zhang Fei fought without ambiguity, among the five sons of Cao Wei, only two had defeated Guan Yu, one of them was Xu Huang, and who was the other?

On the battlefield, it is not a contest of martial arts, but a military battle, as the saying goes, it is useless to rely on brute force and rely on the courage of the flesh to fight a war, mainly relying on the mind.
Cao Wei's five sons, liang generals, were all brave and good at fighting, and were the five generals under Cao Cao who were the best at commanding troops, namely Zhang Liao, Le Jin, Yu Ban, Zhang Gao, and Xu Huang. These five people were able to stand alone and make great achievements for Cao Cao's southern conquest of the northern war.
Of these five people, only two people can fight Guan Yu, of course, this refers to the unified army combat, not a single head, a single head, not Guan Yu's opponent.
In the Battle of Xiangfan, Guan Yu defeated Yu Ban, the highest ranking and most powerful of the five sons, and Yu Ban was the general Zuo at that time.
In the twenty-fourth year of Jian'an (219), Yu Ban's Seventh Army rescued Fancheng Cao Ren, because of an autumn rain, the Han River flooded, drowning Yu Ban's army, Yu Ban was defeated by Guan Yu and became Guan Yu's prisoner.
After Yu Ban's defeat, Cao Cao then sent Xu Huang to rescue Fancheng, and Xu Huang went to the front line and defeated Guan Yu using the tactic of attacking the west with sound east.
Xu Huang claimed to the outside world that he wanted to besiege Guan Yu's toutun and secretly attack Sizuka, Guan Yu saw that Sizuka could not be saved, and then personally led five thousand men and horses to fight, Xu Huang attacked with all his might, Guan Yu had to retreat, Xu Huang pursued, and Guan Yu's army fell into the water and drowned countless people.
The "Biography of Xu Huang in the Chronicle of the Three Kingdoms" records that Huang Yangsheng should attack the siege of Toutun, while secretly attacking The Four Tombs. Hachimi Shizuka was desperate, and he rode five thousand to battle, swung at it, retreated, and then chased after him and entered the army, broke it, or threw himself into the water to die.
In this battle, Xu Huang fully used the tactic of attacking the east and the west to confuse Guan Yu's attention, and when Guan Yu found out, he could not change the battle situation.
Xu Huang was still very brainy in fighting, so after Yu Ban was defeated by Guan Yu, Xu Huang won back a round for Cao Cao and regained a little face.
Of course, at this time, Guan Yu, because he had been fighting for several months, was already tired of fighting, and there was no reinforcement, he suffered a loss, Xu Huang waited for work, and took advantage. Moreover, at that time, Cao Cao had already colluded with Sun Quan to sneak up on Guan Yu from behind, and Guan Yu was at a disadvantage because of the enemy's abdomen and back.
This opportunity was just caught up by Xu Huang, otherwise, Xu Huang was not Guan Yu's opponent.
Among the five sons, in addition to Xu Huang defeating Guan Yu, there was also a person who also defeated Guan Yu, and he was the right general Le Jin.
LeJin defeated Guan Yu when he was in Guan Yu's Northern Province.
After the Battle of Chibi, Cao Cao retreated north, leaving Cao Ren to defend Nan County, Zhou Yu led an army to attack Cao Ren, Cao Ren died, and Zhou Yu fought for more than a year, Cao Cao successively sent several reinforcements to rescue Cao Ren, and Guan Yu attacked, responsible for stopping these reinforcements from the north. Among them, Guan Yu fought with several reinforcements, including Man Yu, Wen Ping, Li Tong and others, including Le Jin.
During the battle, Le Jin had repelled Guan Yu.
The "Biography of the Three Kingdoms Zhile Jin" records: Later from Pingjing Prefecture, Liutun Xiangyang, Guan Yu, Sufi, etc., all went, and the barbarians of the valleys of the Nan County entered and descended.
Of course, at that time, Guan Yu was only fighting guerrillas, and the main task was to prevent Cao Cao from sending reinforcements from the north, to prevent these reinforcements from rescuing Cao Ren in Nan County, Guan Yu only symbolically obstructed it, and harassment did not achieve retreat, so Guan Yu was accompanying Le Jin to play a little, not fighting to the death, otherwise, Le Jin might not be Guan Yu's opponent.
However, Among the five sons, Lejin died very early, and if he died later, he might have a better performance.
