In history, Liu Bei and Sun Quan, a pair of allies, eventually met each other, which is regrettable at the same time, we must also understand that "freezing three feet is by no means a day's cold".

The contradiction between Liu Bei and Sun Quan is gradually expanding, Sun Quan even married his sister to Liu Bei earlier, and after Liu Bei himself captured Yizhou, Sun Quan had already taken his sister Mrs. Sun away, and then the two almost fought each other because of the Jingzhou incident, but because Cao Cao's pressure was too great, they did not fight.

Later, Lu Su, the leader of the pro-Liu faction within the Jiangdong clique, died and was replaced by Lü Meng, who advocated the seizure of Jingzhou, and the alliance between Sun and Liu became even more shaky.

【Mrs. Sun returns to Jiangdong】

According to the "Legend of Yun Bei", after Sun Quan learned that Liu Bei had entered Shu, he sent a boat to welcome his sister back to Jiangdong, but Mrs. Sun tried to take Liu Bei's only biological son Liu Chan with him, and finally Zhao Yun and Zhang Fei intercepted the river and left Liu Chan in Jingzhou.

Historically, Madame Sun, as Sun Quan's sister and Liu Bei's wife, was supposed to be the link between the Sun-Liu Alliance, constantly deepening the ties between Liu Bei's group and Sun Quan's group, and making positive contributions to the stability of the alliance between the two.

It should have been like this, but this lady of the Sun family relied on her identity as the princess of the Sun family to be unscrupulous in Jingzhou, doing whatever she wanted, and even did not take her husband Liu Bei in her eyes, not only connived at the Jiangdong officials and soldiers under her command to do illegal things in Jingzhou, but even when Liu Bei entered the inner room, she let more than 100 maids around her, all of them guard by her side with knives, and gave Liu Bei a horse, and the two separated soon after.

Liu Bei later handed over his own son to her to take with her, but Mrs. Sun thought about how to turn Liu Chan back to Jiangdong. How did Zhuge Liang describe her afterwards: "Recently, I am afraid that Mrs. Sun will change under her elbows and armpits." This is the "good" impression that this Mrs. Sun left on Liu Bei, Zhuge Liang, Guan Yu and other Jingzhou officials.

On the contrary, Mrs. Sun did this, but because of the beautification of books, film and television materials such as "Romance of the Three Kingdoms", she gained a good name in later generations, which is really ridiculous.

In history, Liu Bei and Sun Quan finally broke up, and Mrs. Sun contributed two points even if she didn't have three points of credit.

【Matters of Yizhou and Jingzhou】

Of course, the fundamental reason for the final break between Sun Quan and Liu Bei was that it was difficult for the two sides to reconcile their interests in Yizhou and Jingzhou.

Historically, Jingzhou and Yizhou were not only the necessary targets planned by Zhuge Liang for Liu Bei in the "Longzhong Pair", but also the targets planned by Lu Su for Sun Quan in the "Couch Pair".

Eliminate Huang Zu, enter Liu Biao, the Yangtze River is extreme, according to it, and then build the emperor to map the world, this high emperor's business also. - From "The Couch Pair".

Jingzhou is based on the Han Dynasty in the north, and the South China Sea is exhausted, connecting Wuhui in the east, and Tongba and Shu in the west. Yizhou is dangerous, fertile for thousands of miles, the land of abundance, and Gaozu became an emperor because of it. Liu Zhangyan is weak, Zhang Lu is in the north, the people are rich and do not know how to save compassion, and the wise man thinks of Mingjun. ——From "Longzhong Pair"

Liu Bei wants Jingzhou and Yizhou, and Sun Quan also wants Jingzhou and Yizhou, which is naturally contradictory. After the Battle of Chibi and the Battle of Jiangling, Sun Quan's group had opened the passage to Yizhou, when Sun Quan tried to send troops to seize Yizhou at Zhou Yu's suggestion, and hoped to unite with Liu Bei, but Liu Bei wanted to swallow Yizhou by himself on the one hand, and on the other hand, he was also afraid that Sun Quan would take the opportunity to destroy himself, so he was unwilling to send troops to fight against Liu Zhang on the grounds that he was also a clan, and Sun Quan did not get Liu Bei's help, and Zhou Yu, the beloved general, died at this time, and the crusade against Yizhou was over.

As a result, it didn't take long for Liu Zhang to invite Liu Bei to Shu because Cao Cao sent Xiahou Yuan and others to crusade against Hanzhong, trying to let Liu Bei help him guard the gateway of Yizhou, Liu Bei also took the opportunity to enter Shu, after Sun Quan knew about it, Sun Quan was very angry, who said at the beginning: "Today's alliance attacks each other for no reason, and uses the pivot to make the enemy inherit its gap, which is not a long-term plan." ”

Sun Quan had already lent Nanjun to Liu Bei at that time, and he couldn't prevent him from entering Shu, so he took his sister back to Jiangdong.

After Liu Bei seized Yizhou, Sun Quan wanted to return Jingzhou on the grounds that he already had a base, of course Liu Bei didn't want to give it, how could the meat in his mouth be spit out, so he perfunctory Sun Quan said: "You must get Liangzhou, and you should use Jingzhou to get along." Sun Quan's reaction to this was "hehe", the ghost knows when you Liu Bei will be able to Liangzhou, and after you get Liangzhou, you may also say, "You must be subordinate, and you should be with Jingzhou." ”

So Sun Quan directly sent governors to the three counties of Changsha, Lingling and Guiyang under the command of Jingzhou, saying that although Jingzhou could not be taken back, at least I wanted half of it, and the result was driven out by Guan Yu.

Then, then Cao Cao came out to steal the show, Liu Bei and Sun Quan failed to fight, Liu Bei remembered the fear of being once dominated by Cao Cao, so he decisively negotiated peace with Sun Quan, the two sides divided Jingzhou equally, and demarcated in Xiangshui, Jiangxia County, Changsha County, and Guiyang County belonged to Sun Quan, and the South County, Lingling County, and Wuling County of Jingzhou belonged to Liu Bei, which was equivalent to Liu Bei Liu Bei handing over Changsha County, Guiyang County and part of Jiangxia County to Sun Quan, and the matter of Jingzhou was over.

But this does not mean the end of the matter, the relationship between Sun Quan and Liu Bei in the Xiangshui demarcation has only been temporarily eased, and has not been fundamentally improved, Liu Bei originally did not have much good feelings for Sun Quan and others because of Mrs. Sun's affairs, and then Sun Quan seized the land of the three counties, and after Liu Bei's power expanded, he gradually stopped taking Sun Quan in his eyes, and no longer valued the alliance with Sun Quan, but there was no further action under the pressure of Cao Cao.

And after Sun Quan recaptured the three counties, he was actually not satisfied, coupled with Liu Bei's change of attitude towards Sun Quan, Sun Quan also began to reconsider the relationship with Liu Bei, Liu Bei's continuous expansion of power had caused the fear of Sun Quan as an ally at that time, at this time, Lu Su, who was pro-Liu faction, died, and the voice of Liu Bei within Sun Quan's group was low.

After Lu Su's death, Sun Quan was originally ready to send Yan Jian to replace him, but Yan Jian thought that he was not capable enough, so Sun Quan turned to Lu Meng to replace him.

Lü Meng used to be Zhou Yu's subordinate, and in history, he and Zhou Yu had the same view of Liu Bei's group, both wanted to take Jingzhou as their own, and under Lü Meng's instigation, Sun Quan launched a new round of offensive against Jingzhou.
