Liu Bei was originally a low-level peddler, but this person was very benevolent and heavy on feelings, so he gained a group of brothers who were loyal to him to help him fight the world. However, many people still sigh when they mention Liu Bei.
In his early years, Liu Bei met the first two brothers in his life, not so much brothers as nobles, these two were Guan Yu and Zhang Fei. After the worship, the three embarked on the road of uprising. Both of his younger brothers were warriors who could fight one hundred times. Liu Bei was very accurate in seeing people, and the two of them could not only protect him, but also kill the enemy bravely on the battlefield, and most importantly, they were loyal people without small calculations.
Later, they defected to Yuan Shao together, and Guan Yu helped Yuan Shao "wen wine and cut Huaxiong", which shocked the world. In the Battle of Tiger Prison Pass, Lü Bu was unstoppable, and even beheaded many of Yuan Shao's generals, and it was also their three brothers who stood up and fought with Lü Bu, although in the end they were not able to capture Lü Bu, but they repelled Lü Bu and greatly increased the morale of the rebel army. However, it is not enough to have loyal warriors, no matter how powerful a warrior can fight a hundred enemies, but in the end it is only one person, and his strength is limited. The reality is that Liu Bei ran around after leaving home yuan shao's account, and basically did not fight a single victorious battle.
At this time, Xu Shu recommended a world wizard to Liu Bei, saying that he knew the heavens and the earth, and he would be able to help Liu Bei "revive the Han Room", and the facts also proved that Xu Shu was right. The man he recommended was called Zhuge Liang, and Liu Bei did not hesitate to visit Zhuge Liang three times before inviting him out of the mountain to assist himself. After Zhuge Liang became Liu Bei's adviser, he helped him take Jingzhou, took Yizhou, joined Forces with Sun Wu in the east, repelled the Cao army at the Battle of Chibi, and later planned the Battle of Hanzhong... Until the deaths of Guan Yuhe and Zhang Fei, the strength of Liu Bei's army was on the rise under Zhuge Liang's planning. Unfortunately, Guan Yu was killed by Sun Wu's ambush because of his arrogance, and Zhang Fei was arbitrarily whipped by his subordinates due to his tyrannical temperament, and was finally killed by his own people.
After the death of the two younger brothers, Liu Bei was bent on revenge, completely disregarding Zhuge Liang's persuasion, and led his own troops to attack Wu, only to be defeated, from this time on, the Shu state went downhill, and Liu Bei was seriously ill shortly after the defeat of Liu Bei, he knew that his time was short, so he planned to entrust all the aftermath of Shu Han to Zhuge Liang. As we said earlier, Liu Bei has always been very accurate in looking at people, he has taken a fancy to Guan Yu and Zhang Fei's martial courage, and he has also taken a fancy to Zhuge Liang's wisdom, which is the basis for his ability to establish the foundation of Shu Han, and Zhuge Liang has always been very convinced of Liu Bei's standards. However, before Liu Bei died, zhuge Liang did not approve of the person who recommended him.
This person was Wei Yan, Wei Yan was a general, and when Zhuge Liang was still in Jingzhou, he wanted to get rid of him, thinking that he was not in the right mind, and if he was allowed to be a general in the Shu kingdom, in the near future, he was likely to rebel. However, Liu Bei did not think so, and Liu Bei still used him very much after Wei Yan surrendered to the Shu state, and after taking Hanzhong, the appointment of Wei Yan as the Taishou of Hanzhong was the best example. However, it turned out that Liu Bei did look away, and although Wei Yan was a man with outstanding ability, his heart was not on the side of the Shu Kingdom, and he could not be as dedicated to Shu as Guan Yu and Zhang Fei.
Although Zhuge Liang did not approve of Liu Bei's approach, he was a courtier after all, and he was a loyal courtier. After Liu Bei's death, Shu Han also had almost no available generals, so he had to rely on Wei Yan, but Zhuge Liang, because he was defensive against him, would never give Wei Yan real military power. In 234 AD, as soon as Zhuge Liang died, as he expected, Wei Yan rebelled against Shu, bringing a heavy blow to the Shu state. Of course, Liu Bei looked away at a person, and Zhuge Liang also looked at a person who had lost his eyes. Before Liu Bei's death, in addition to explaining that Zhuge Liang could use Wei Yan, he was also reminded not to reuse Ma Chen. This time Liu Bei was right, but Zhuge Liang still did not agree, Ma Mo and he have always been good friends, the two often discuss military together, what do not understand will also come to Zhuge Liang in time, equivalent to Zhuge Liang half of the apprentice, so Zhuge Liang attaches great importance to him.
The reason given by Liu Bei was that although Ma Mo was the leader of the military, he could not really lead the troops to fight. Sure enough, in 228 AD, Zhuge Liang's first Northern Expedition, all the way north, almost succeeded, but lost in the hands of a person, this person is not a General of the Wei Army, it is his Ma Mo. He sent Ma Mo to guard the main grain and grass road of the street pavilion, but Ma Mo did not know how to use troops flexibly, and set up camp on the mountain, which eventually led to the Shu army being besieged by the Wei army and then defeated. The supply of grain and grass in the rear was insufficient, and the soldiers on the front line still had the strength to fight, which eventually led directly to the failure of the Northern Expedition. Zhuge Liang also beheaded Ma Mo with military law, but it was also too late to regret it! It can be seen that in excellent people, mistakes can also be made. It just so happened that Zhuge Liang looked at the wrong person, Liu Bei looked at the wrong person, and these two people brought great damage to the national power of the Shu state!
