The weather in Heihe City is Sun Wu.
Of course, I didn't expect that Liu Bei, who fought in the battlefield all his life, lost to the young Lu Xun. In this war, Liu Beijun was almost completely annihilated, and tens of thousands of people were killed. According to Fu Zi's records, Wu Jun wiped out more than 80,000 Shu-Han troops, only Liu Bei survived. In any case, the battle of Yiling was a heavy loss to Shu Han, even no less than Guan Yu's carelessness in Jingzhou. Then, the problem came. Liu Bei lost almost all his main forces in the battle of Yiling. Why didn't Soochow seize the opportunity to annex Shu Han?

First of all, after the battle of Yiling, Wu Dong did not continue to attack, so as not to expand the results. According to historical records such as the reflection, after Liu Bei fled to Yong 'an Bai Di City, generals Pan Zhang, Xu Sheng and others advocated the pursuit of 56 points of victory and expanded the results. But at this time, Liu Bei gathered his scattered forces, and Zhao Yun's rear army came to help, and the Yongan garrison was close to 20 thousand. As far as the battle of Yiling is concerned, some of Liu Bei's troops fled after being defeated. Knowing that Liu Bei is in Baidicheng, he will naturally gather in this place. Coupled with the reinforcements brought by Zhao Yun, the Shu-Han army in Yongan is close to 20,000. Although it can't be compared with Wu Dong's army, Liu Bei is now guarding the city, and the disadvantage in strength has been made up by the fortified city.

Furthermore, as far as Liu Bei's Yong 'an Bai Di City is concerned, it is located at the top of Bai Di on the north bank of the Yangtze River at the mouth of Qutang Gorge, with Kuimen in the east and Bazhen Mountain in the west, surrounded by mountains on one side and water on all sides, and backed by the Gorge. It is the gateway to the Three Gorges, so it is easy to defend but difficult to attack. As for the passage between Jingzhou and Bashu, in ancient times, there were only the Three Gorges of the Yangtze River. If Sun Quan and Soochow want to attack Shu Han, they must pass through the Three Gorges Passage of the Yangtze River.
But Liu Bei also understood this truth, so he assembled troops at the Three Gorges Pass of the Yangtze River in Baidicheng, Yong 'an, avoiding the risk of Shu Han being breached. It is worth noting that when Shu Han perished, Wu Dong wanted to seize the territory of Shu Han. However, Luo Xian, the general of Shu Han, held fast to Yong 'an with thousands of troops, leaving tens of thousands of elite soldiers in Wu Dong helpless and unable to get a slice of the broken Shu Han.

Therefore, it was Liu Bei's and Zhao Yun's troops that concentrated in Baidicheng, Yong 'an, which made Sun Quan and Lu Xun understand that if they wanted to annex Shu Han, they had to pay a heavy price. At the very least, they must mobilize Wu Dong's main force to attack Yong 'an, so that they can finally attack the Chengdu Plain of Shu Han. However, Cao Pi, who was eyeing one side, did not give Sun Quan and Lu Xun more time to think.
A month or two after the battle of Yiling, Cao Wei's army will attack Wu Dong. According to historical records such as the History of the Three Kingdoms, before the attack on Guan Yu and the capture of Jingzhou, Sun Quan got in touch with Cao Cao to avoid being caught between Scylla and Charybdis when confronting Shu Han. However, after the victory of Yiling War, the alliance between Cao Wei and Wu Dong has gradually drifted away. Therefore, in 222 AD 10, Cao Pi expressed his resolute attitude of conquering the north and seeking Sun Quan.

Finally, in the winter of AD 222, Cao Pi promised to go south, and all the soldiers went hand in hand. Cao Zhen and Cao Xiu triumphed, defeated Sun Sheng, defeated Lv Fan, set fire to Zhu Gejin, and almost captured Jiangling. When Wei Wendi Cao Pi showed his muscles, Sun Quan and Wu Dong were frightened and had no idea to annex Shu Han.
At this critical moment when Cao Pi's army was under siege, Sun Quan mobilized his main force to refuse to defend the river, and several fronts collapsed or fell. Only Huan Zhu and Xu defeated Coss all the way. But overall, Soochow is obviously at a disadvantage. Unexpectedly, however, Cao Pi suddenly encountered an epidemic disease, and the cold weather in winter was not conducive to the attack, so Cao Wei withdrew from Soochow. After that, Cao Wei's offensive pressure was still there, and Shu Han gradually recovered, making it even more impossible for Sun Quan and Soochow to have any ideas.
