In 219, Guan Yu launched the Battle of Xiangfan, but because he did not receive strong support, he was attacked by Cao Cao and Sun Quan, defeated Maicheng, and then captured. Some people say that liu bei and Zhuge Liang borrowed the swords of Cao Cao and Sun Quan to get rid of Guan Yu, who could not be left behind. Is this the truth? Personally feel that this is not possible, the analysis is as follows.
First, if Guan Yu's death was Liu Bei borrowing a knife to kill someone, then the price was too high.
When Guan Yu died, not only tens of thousands of elite soldiers were buried, but also most of the rich Jingzhou. At that time, Shu Han only occupied Jingzhou, Yizhou, and Hanzhong, of which Yizhou had the largest territory and Jingzhou was the richest. Jingzhou is not only rich, but more importantly, Jingzhou's geographical location is dangerous, and it can be attacked and defended.
Zhuge Lianglongzhong especially valued Jingzhou, and he thought that one day in the future, when the world changed, he would send a general to send troops from Jingzhou, and the lord Liu Bei would attack Wei from Hanzhong, and he would be able to destroy Cao Cao by attacking in two ways. Therefore, even if Liu Bei felt that Guan Yu was not very obedient and became an independent kingdom in Jingzhou, he would not abandon Jingzhou in order to get rid of Guan Yu.
Second, Liu Bei, Guan Yu and Zhang Fei Taoyuan were righteous, and their feelings were deep and righteous, and they would not break their oaths.
At that time, Liu Bei, Guan Yu, and Zhang Fei met by chance, and the more they talked, the more speculative they became, so they married brothers with different surnames in Zhang Fei's back garden - Taoyuan. The three of them made a vow not to be born in the same month of the same year, but to die in the same month of the same year", and the three of them were tied together. Liu Bei, Guan Yu, and Zhang Fei also did the same, no matter how big the difficulties they encountered, the three of them all advanced and retreated together. The relevant descriptions in the speech are as follows:
Nian Liu Bei, Guan Yu, and Zhang Fei, although they have different surnames and are married as brothers, they work together to save the poor and help the crisis; report to the state and go down to Lishu. I do not want to be born on the same day of the same month of the same year, but only on the same day of the same month of the same year. Emperor Tianhou Earth, true to this heart, ungrateful, heaven and man fighting together!
Although Liu Guanzhang and the three are not biological brothers, they are better than biological brothers. If Liu Bei abandoned Guan Yu, it was equivalent to abandoning Zhang Fei. Because Zhang Fei is very affectionate and righteous, he cannot stand Liu Bei who is "treacherous". Therefore, Liu Bei would not use a knife to kill Guan Yu in order to eliminate the potential threat.
Third, if Liu Bei and Zhuge Liang killed Guan Yu with a knife, there would be no benefit to them.
Borrowing a knife to kill people always has to be good. However, according to the plot development in the Romance of the Three Kingdoms, since Guan Yu carelessly lost Jingzhou and lost his life, Shu Han began to decline. Their energetic and positive spirit is gone. In short, Guan Yu's death was a bunch of bad things for Liu Bei, and there was no benefit at all.
In ancient times, there were many things that killed people with knives, and they did not hesitate to pay a little price for this, but later they could get greater benefits. Now, Liu Bei lost Guan Yu and Jingzhou, and did not gain any benefits in the later period, and also lost the army of Yizhou.
Fourth, if Liu Bei and Zhuge Liang had killed Guan Yu with a knife, Liu Bei would not have launched the Battle of Yiling and a great war with Eastern Wu.
However, in fact, just after Guan Yu's death, Liu Bei wanted to launch a war against Eastern Wu, but for various reasons, it was not immediately implemented. Later, Zhang Fei was also killed by his subordinates Fan Jiang and Zhang Da because he was overly sad and drunk a lot of alcohol because he missed Guan Yu's death. Liu Bei also began planning a campaign against Eastern Wu two years later, just after he ascended the throne.
This shows that Liu Bei really cares about Guan Yu, and in order to avenge Guan Yu, he will not hesitate to lose all his belongings. In the rendition, Liu Bei was burned by Eastern Wu Luxun for 700 miles, burned to the ground, and only a few hundred people fled back to the White Emperor City, where they were devastated and died of illness a year later. The Chronicle of the Three Kingdoms chronicles the following:
The first lord was ill, and he was lonely in Cheng Xiangliang, and Shang Shu made Li Yan his deputy. In the summer of April, the first lord died in the Yong'an Palace, when he was sixty-three years old.
Summary: Guan Yu is too important for Liu Bei, and Liu Bei cannot deliberately borrow the hands of Cao Cao and Sun Quan to get rid of it because of jealousy. Liu Bei was very trusting of Guan Yu and entrusted him with such a large Jingzhou. The above four reasons fully show that Liu Bei and Zhuge Liang will not abandon Guan Yu, nor will they lose such a rich Jingzhou.
