Judging from the whole process of the battle of Xiangfan, Guan Yu seems to have completely controlled the Hanjiang waterway from the south of Xiangyang to hundreds of miles north of Jing. It seems that Zhuge Liang's administration of Jingzhou was quite successful before. Therefore, after Liu Bei and Zhuge Liang went to Shu to reinforce Jingzhou twice, Guan Yu was able to form an overwhelming advantage over Cao Wei's war zone in the north of Beijing. He not only surrounded Xiangyang and Fancheng, but also killed Pound and dealt a heavy blow to the Seventh Army who came to reinforce. After the news came out, people in Cao Tong area near the north of Beijing were shocked and responded to Guan Yu in succession, rising up against Wei. South of Xuchang, a fire broke out. Even Yecheng, Cao Cao's stronghold, was rebelled, and the children of Jingzhou officials under Liu Biao who surrendered to Cao Cao in large numbers were also involved. Cao Pi, who stayed in Yecheng, killed thousands of people. We should know that the clan relations of these thousands of people are all in Xiangfan area. After this incident, Cao Wei's reputation in the north of Beijing was completely lost, and it was only a matter of time before Guan Yu won it.
However, the pass could not be delayed any longer, because Cao Cao's reinforcements had arrived from all directions, and Guan Yu had to win Xiangfan as soon as possible in order to maintain the situation of winning with a strong city. And he relied on the public security to guard Jiangling, and Sun Quan couldn't pull it out any day (note 1), so he simply transferred most of the troops behind Jiangling to the front line in northern Beijing, trying to get Coss who were at the end of the road as soon as possible, which finally gave Lv Meng a chance.
Note 1: According to Shui Jing Zhu and Yuanhe County Records, Guan Yu once built Jiangling City on a large scale, while according to the biography of the Three Kingdoms Dong Zhaochuan, Dong Zhao said to Cao Cao, "Yu is a girder. If you rely on two cities to defend, you will not retreat quickly."
It turned out that the dispute between the three counties in the south of Jingzhou and the death of Lu Su, an important promoter of the alliance, made the alliance relationship between Sun and Liu face a crisis. At this time, Sun Quan was still sober. He proposed to marry Guan Yu, hoping to marry Guan Yu's daughter to Prince Sun Deng. If this is successful, Guan Yu's daughter may become the queen or even the empress dowager of Dongwu in the future, and the Guan family will also be important officials and consorts of Dongwu, and become a link between the two countries. However, Guan Yu was arrogant, flatly refused, and his words were rude, which not only humiliated Sun Quan, but also caused a major rift in the relations between the two countries. So Lu Su's successor put forward a complete plan to attack Jingzhou to Sun Quan, and finally realized it through a series of tactical means such as diplomatic confusion, secretly uniting Cao, crossing the river and buying people's hearts.

Then, something that shocked everyone happened, as if the war had gone downhill overnight. In August, Guan Yunchang was also the top gun of Changfeng Wan Li, and the Seventh Army was full of sublime China, but it was not good either. In October, Jiangling was successfully captured by Lv Meng (note 2), and then Cao Cao's reinforcements arrived one after another. Guan Yu hesitated a little, and the route to the three northeastern counties was blocked. Guan Yu still has a chance to go south to recapture Jiangling. However, Wu Jun's progress is too fast. 1 1 month, while Lv Meng pacified Nanjun, Sun Quan sent Pan Zhuo, commander-in-chief of Shu Han, to attack Wuling County, defeated Wuling to make Fan Xuan, cut it, pacified Wuling County, and then moved to Lingling County, defeated a captain in the north of Lingling County, and also cut it (see Old Biography of Xiangyang).
Although Shu Han still had a strong force in Zigui area, local generals and local tyrants such as Zhan Yan, Chen Feng, Wenbu and Deng Kai also fought to the death, but after all, they were not the main force and were easily defeated by Lu Xun. Fu Deng, the satrap of Fangling in Shu and Han Dynasties, and Guo Mu, the satrap of Nanxiang, led troops from Fangling to the south of Shennongjia, trying to get through the Three Gorges Passage, but they were all defeated by Lu Xun. In just one month, tens of thousands of Shu-Han troops were beheaded and captured by Lu Xun. Guan Yu's troops saw that reinforcements were hard to come by, and the tide was gone, and they fled in succession. Guan Yu defeated Maicheng, leaving only ten riders in the end. They tried to climb mountains and flee to Shu Han, but they were chased and intercepted by Wu Dong army. In December, Guan Yu was captured and refused to surrender, and was finally killed by Sun Quan.
