After Ma Chao surrendered to Liu Bei, he was made a general of Pingxi, but it led to a dispute over Guan Yu preparing to enter the Sichuan tournament, what was the reason why Guan Yu, a general, had to behave in this way? If Liu Bei really allowed Guan Yu to enter the Sichuan Tournament, would Guan Yu really be able to fight horses? Where is the gap between him and Ma Chao?

【Guan Yu's Concerns】
Ma Chao is a relatively popular tiger general in the Romance of the Three Kingdoms, and he does not appear too much in martial arts, but he has two classic pre-battle competitions with Zhang Fei and Xu Chu with his outstanding martial arts. After the defeat of several generals of Cao's army at Tongguan, Cao Cao was killed and his robes were abandoned, and Ma Chao was once compared with Lü Bu. In terms of strength, Guishun Liu Bei is indeed like a tiger, Guan Yu's proposed competition does seem to have the demeanor of a general, and Guan Yu's mind is not broad enough for an instant. In fact, all this still has another intention, when Guan Yu's challenge letter arrived in Chengdu, Liu Bei instantly understood, and Zhuge Liang also explained very clearly, so Guan Yu was very happy, showing Zhuge Liang's reply to everyone around him, since then his concerns have been nothing, and he has no intention of challenging Ma Chao in Sichuan, what concerns does Guan Yu have that makes Guan Yu so troublesome?
First of all, Ma Chao's entry into Sichuan to get general Pingxi was the highest position in Liu Bei's army, higher than Guan Yu's general Lang Kou, and all this was also Liu Bei's helpless choice. Although Ma Chao was a general under Zhang Lu, but he was the son of Ma Teng, he was also a prince of Yizhen, and in terms of identity, he was of equal rank with Liu Bei, and the reason why Liu Bei did not assassinate Liu Zhang at the banquet was because he paid attention to the good name of benevolence and righteousness, and he also treated Ma Chao, a declining prince, with special courtesy, and the external feeling was that he was barely one level lower than Liu Bei, so his status was higher than Guan Yu, and Guan Yu was still only a general under Liu Bei, and his rank could not exceed Ma Chao. In addition, Ma Chao played a great role in forcing Liu Zhang to surrender, and although Ma Chao had just surrendered Liu Bei, it was natural to become Liu Bei's first general.
The most influential on the status is Guan Yu, Zhang Fei, Zhao Yun and Huang Zhong four people, Zhao Yun and Huang Zhong will not have too much to think about, although Zhang Fei is rough, but his character is to treat the low-level soldiers roughly, to treat capable middle and high-level literati and generals are very respectful, Ye Mengguan Battle He and Ma Chao have a feeling of not fighting and not knowing each other, he will not have too much to think about. However, Guan Yu is a figure who attaches great importance to his reputation, and Guan Yu, who has always been the head of the crowd, cannot tolerate the new Ma Chao being above his position.
Secondly, Guan Yu was not familiar with Ma Chao's character and had doubts, there was a precedent for the capricious Lü Bu to seize Xuzhou, although Ma Chao was not capricious, but it was also too good in front of the princes, in Guan Yu's mind, Ma Chao would at least not be as simple as Huang Zhong and Zhao Yun after he threw himself into Liu Bei's army, and it was not good to see a second Xuzhou. Zhang Fei only fought with Ma Chao into a draw and could not completely defeat Ma Chao, so Guan Yu wanted to come to Xichuan to psychologically conquer Ma Chao and not let Liu Bei, the eldest brother of Jieyi, suffer losses. This letter also indirectly reminds Liu Bei to beware, Liu Bei also understands the reason for Guan Yu's impulsiveness, and Zhuge Liang's reply also makes it very clear that the status is definitely not as good as Guan Yu, and in martial arts, it is only Zhang Fei and Zhao Yun, which are far lower than Guan Yu, and secretly also mean that Liu Bei will be wary of Ma Chao, and that general Pingxi is only a fictitious position, and wants Guan Yu not to think about it, so Guan Yu laughed and said, "The military master knows my heart."
【Guan Yu's strength】
Zhuge Liang solved Guan Yu's doubts through letters, so if Guan Yu really entered the river, could he have the strength to defeat Ma Chao? First of all, let's take a look at the characteristics of Guan Yu, at the peak of his life, Guan Yu relied on an eighty-two-pound Green Dragon Yanyue Knife, coupled with the speed, accuracy and fierceness of the sword technique, leaving no chance for the opponent, and killed the Western Liang general Hua Xiong. Later, he got Lü Bu's red rabbit horse, and after five levels and six generals, Yan Liang, Wen Ugly, and Cai Yang also fell under his sword. He also became the representative of the invincibility of the Three Kingdoms after Lü Bu.
However, Guan Yu's weakness is also obvious, first of all, his defense is particularly low, compared to his number of hit arrows is the most, from Cao Ren, Pound De to the nameless Han Fu have shot him, Huang Zhong because he can't bear to shoot to save Guan Yu from an arrow. The second is that Guan Yu's knife technique focuses on preemptive attack, relying on the courage of the early stage, that is to say, the opponent must be defeated within twenty rounds, and once it enters the endurance struggle in the middle and late stages, Guan Yu's strength will quickly weaken. Finally, Guan Yu's physical strength declined particularly quickly, and Guan Yu had just passed his peak and was less than fifty years old when he was in Changsha, and he lost his original courage. In the later period, even Pound and Xu Huang could not be defeated.
【Ma Chao with fast guns】
Ma Chao's ancestral marksmanship is very exquisite, his biggest characteristic is fast and fierce, Zhang Gao is also a major general in Cao Cao, but he lost to Ma Chao in twenty rounds, including Ma Chao's gun speed and vengeful killing heart. And Xu Chu was the first general of the Cao Army, and after hundreds of rounds, he was finally under the speed of Ma Chao's gun, and he was still slightly inferior when he abandoned the knife and carried the gun. And his dark weapon bronze hammer, although not first-class, is helpful in defeating opponents of strength. However, Ma Chao has one of the biggest shortcomings is that he is impatient, and in the big battle between Ye Mengguan and Zhang Fei, there is no mistake in strength, but because Ma Chao cannot defeat Zhang Fei and there is impatience, so there is also a way to throw a copper hammer dark weapon.
Ma Chao will not have an advantage no matter when he encounters Guan Yu at the peak, and If Ma Chao, who is more than ten years younger than Guan Yu, met Guan Yu at the peak in the early stage, he may not be luckier than Yan Liangwen, and it will be difficult for him to defeat Guan Yu at that time. However, although Guan Yu was famous at his peak, he was far inferior in physical strength and speed, and although he had bold words and wanted to cut down Pound Xu Huang, he was only weak in heart, and it was also difficult for him to defeat Ma Chao. At the peak of Ma Chao's time, not to mention that he had an advantage in marksmanship speed and dexterity, perhaps even Ma Chao's dark weapon copper hammer would also hurt Guan Yu, I believe that Ma Chao's dark weapon technique would not be inferior to Han Fu who shot Guan Yu with arrows, and at this time, Guan Yu's fast and accurate stable knife was already difficult to cause damage to Ma Chao.
