After Xu Shu surrendered to Cao Cao, what was the final outcome?

Xu Shu entered Cao Ying without saying a word", this is a historical allusion known to women and children. For this allusion, it comes from the literary work "Romance of the Three Kingdoms". In Luo Guanzhong's "Romance of the Three Kingdoms", there was such a plot story, that is, Xu Shu became Liu Bei's military advisor by self-recommendation, but was deceived to Cao Ying's design by Cao Cao's strategist Cheng Yu.

At that time, Cao Cao sent a large army to attack Fancheng, where Liu Bei was stationed, and at Liu Ye's suggestion, Cao Cao sent Xu Shu to Fancheng to persuade Liu Bei to surrender, but after Xu Shu arrived in Fancheng, he told Liu Bei that the army was coming, so that Liu Bei could prepare early. Liu Bei wanted to keep Xu Shu, but Xu Shu was afraid that the world would laugh at him, so he refused on the grounds that Liu Bei was assisted by Zhuge Liang, and told Liu Bei that although he was in Cao Cao's camp, he swore not to offer a plan for Cao Cao.

On this basis, after "Xu Shu entered Cao Ying" and the "Guan Yu descended to Cao" incident, it evolved into the idiom "being in Cao Ying, and the heart is in Han". Of course, this is a fictional plot in "Romance of the Three Kingdoms", and in official histories such as "Three Kingdoms", there is no saying that "Xu Shu entered Cao Ying without saying a word". Moreover, Zhuge Liang couldn't help but sigh after learning about Xu Shu's ending in Cao Wei.

So, the question is, what will be the final outcome after Xu Shu surrenders to Cao Cao? Why did Zhuge Liang sigh again and again when he knew about it?

First of all, Xu Shu's real name is Fu, and he is a son of a poor family. In the sixth year of Zhongping (189), Xu Shu avenged others, fled with his hair scattered, and was caught by officials. The official asked Xu Shu what his name was, and Xu Shu didn't say a word, so the official tied Xu Shu to a pillar to make a look of preparing for dismemberment, and beat the drum to order the people in the surrounding markets to come out and identify him, but they didn't dare to say that they knew this person.

Later, Xu Shu's henchmen came together to rescue Xu Shu (later, when Xu Shu was bigraphed in the Wei history book "Wei Luo", his real name Xu Fu was still used). Xu Shu was very grateful, so he stopped dancing with guns and sticks, and changed his usual temperament to study. As a result, for Xu Shu in his youth, he can be called a chivalrous man who is happy to take revenge.

Of course, after some setbacks, Xu Shu finally woke up and embarked on the road of studying.

In the second year of Chuping (191), after Dong Zhuo usurped the power of the Eastern Han Dynasty, it caused a crusade against Cao Cao, Yuan Shao, Yuan Shu and other princes. On this basis, the Central Plains naturally fell into war. In this regard, in order to avoid chaos, Xu Shu went south to Jingzhou with Shi Tao of the same county to live.

After arriving in Jingzhou, Xu Shu got acquainted with Zhuge Liang and had a friendly relationship.

Therefore, in the official histories such as "Romance of the Three Kingdoms", Xu Shu and Zhuge Liang have formed a relatively deep friendship. And this is also an important reason why Zhuge Liang and Xu Shu are each their masters, and the former is still investigating the news of the latter. In the sixth year of Jian'an (201), Liu Bei was defeated by Cao Cao and went south to attach himself to Liu Biao, who asked Liu Bei to be stationed in Xinye to defend against Cao Cao.

During this period, Xu Shu chose to defect to Liu Bei, who lived in Jingzhou.

After he surrendered to Cao Cao, he did not offer a single plan for Cao Cao, and finally died of illness in Cao's camp.

After Xu Shu surrendered to Cao Cao, the final outcome was to do nothing and return to the mountains and forests, and not long after Cao Cao detained Xu Shu's mother, his mother died, and Xu Shu also returned to the mountains and forests.

After Xu Shu surrendered, he did not offer a plan for Cao Cao in his life. Cao Cao also knew that he did not arrange important official positions for Xu Shu.

After Xu Shu surrendered to Cao Cao, he stayed on Cao Cao's side, but he never offered a plan for Cao Cao in his life.
