Talking about the fierce generals around Liu Bei, people's first impression is bound to be Guan Yu and Zhang Fei, in the "Romance of the Three Kingdoms", the three people righteously married Jinlan, in the main history of the relationship between the three people is also named Junchen, actually brothers, Guan Yu and Zhang Fei are all enemies, all the way to follow Liu Bei from scratch, it can be said that loyalty is the same, but Liu Bei only arranged for Guan Yu town to guard Jingzhou after success, but did not arrange For Zhang Fei to guard Hanzhong, but let him garrison Langzhong in the non-border, is this a big deal?
For this matter, many conspiracy theorists began to open their minds again, the first point of view put forward is that Liu Bei is afraid of Zhang Feigong's high shock lord, deliberately put it in the position of Langzhong, this view is obviously untenable, although the world has been divided into three divisions at that time, but the world is uncertain, Liu Bei still needs Zhang Fei to charge forward in the future, how can it be estimated that it will be idle?
The second point of view is that Zhang Fei is a good wine and has a violent personality, which is not suitable for defending the city, generally speaking, those who put forward this point of view are bound to come up with the case of Zhang Fei's drunkenness and loss of Xuzhou, so we will take a look at the historical truth today. First of all, Zhang Fei drunkenly lost Xuzhou This is the saying in the "Romance of the Three Kingdoms", saying that Zhang Fei drunkenly played drunk and beat Lü Bu's old man Cao Bao, Cao Bao was resentful, and wrote a letter to call Lü Bu to take Xuzhou, so let's see how much credibility this matter is?
According to the Chronicle of the Three Kingdoms, "The Lower Pi Guards rebelled against Cao Bao and intermittently embraced the cloth. ”
According to the "Hero's Record", "Zhang Yide and Xia Pi Xiang Cao Leopard fought together, Yide killed the leopard, and there was chaos in the city, and he did not believe it." Danyang soldiers have a thousand people tun west baicheng north, General Wen came to the east, the size of the enthusiastic, such as resurrection. The general marched to the west gate of the city, and the Danyang army opened the door to the general."
From the historical data, Zhang Fei's loss of Xuzhou was indeed related to Cao Bao, but there is no information mentioning that Zhang Fei lost Xuzhou because he was drunk, and the real situation at that time was that Liu Bei went to fight with Yuan Shu and took most of the soldiers and horses, so the remaining defenders in Xuzhou were not many, and the people were unstable, and Cao Bao, the next Pi Xiang, fought with Zhang Fei as a ground snake, did not fight, and rebelled. This led to Zhang Fei losing Xuzhou. Zhang Fei, as a ten thousand enemies, had no less ability to defend the city than Wei Yan. Therefore, this argument is also untenable.
So why did Liu Bei let Zhang Fei, who was an enemy of thousands of enemies, go to Langzhong for seven consecutive years, and Zhang Fei had no complaints? The only answer is that there is an unseen importance in Langzhong.
First of all, langzhong's geographical location is very special, it is the throat of the river, if Hanzhong is the first barrier of Western Shu, then Langzhong is the second barrier, one is that if Hanzhong is difficult, Zhang Fei in the town guard lang can quickly send troops to support, even if Hanzhong is breached, then the enemy wants to march into Chengdu or will be blocked by Zhang Fei in the town guard Lang; second, Langzhong is not far from Chengdu, if there is a change in Chengdu, then Zhang Fei in the town guard Lang can also react quickly and return to defend Chengdu; third, if there is a change in Jingzhou, Zhang Fei could go down the river to Jiangzhou to provide support, which is also the reason why after Guan Yu's death, Liu Bei let Zhang Fei send troops from Jiangzhou, but unfortunately people are not as good as heavenly calculations, Zhang Fei died before he could succeed in his division; finally, Zhang Fei was not only defensive in Langzhong, but also could attack and harass Cao Wei's Longyou region and Wudu and Yinping, which can be said to be able to disturb the enemy, retreat can support Hanzhong and defend Chengdu, and this strategic place cannot be guarded by his henchmen.
Secondly, the cultural and economic significance of Langzhong is equally important, successive dynasties and dynasties langzhong have been highly valued, so there are thousands of years of cultural accumulation, has long become the political, economic and cultural center of northern Sichuan, it is now also one of the four ancient cities in China, with anhui Huizhou ancient city, Shanxi Pingyao ancient town, Yunnan Lijiang ancient city is equally famous, there are always people affected by the "Romance of the Three Kingdoms", saying that Zhang Fei has courage and strategy, but in fact, Zhang Fei can not only have courage, but also have strategy, Langzhong under Zhang Fei's governance, the people live and work in peace, commerce and commerce prosperity, It contributed greatly to the economy and military of the Shu state.
Therefore, compared with Hanzhong, Langzhong needs more confidants to guard, and Zhang Fei is also well aware of this truth, so he did not compete with Wei Yan for the position of Hanzhong Taishou, but personally sat in Langzhong to escort Chengdu, which is the most reflective of the mutual trust between their brothers.
