I. Xu Tian in the Romance of the Three Kingdoms
In the Romance of the Three Kingdoms, the Xu Tian Siege Incident was an open contest between Cao Cao and Emperor Xian of Han, which directly led to the "Yidai Zhao Incident".
The cause was that after Cao Cao destroyed Lü Bu, he brought Liu Bei to see Emperor Xian of Han. Emperor Xian of Han was very excited, it turned out that he still had such a cattle uncle, and it seemed that there was hope for overthrowing Cao Cao and regaining power. Therefore, Emperor Xian of Han openly recognized Liu Bei as an uncle and also set up a family banquet.
At this moment, it aroused the vigilance of Cao Cao's clique, which all thought it was not a good thing and demanded that Liu Bei be removed quickly. Cao Cao objected, believing that Liu Bei was not worried enough now and should first deal with the lieutenant Yang Biao. Therefore, Cao Cao sent people to frame Yang Biao for colluding with Yuan Shu and depose Yang Biao.
Cheng Yu saw Cao Cao's intentions and suggested to Cao Cao: "Now that the Ming Dynasty is becoming more and more famous, why not take advantage of this time to do the things of kingship?" ”

This means that now we have suppressed the forces of the loyal Han Dynasty almost completely, and even the Tai wei Yang Biao has been eliminated. Boss, you should be able to claim the king's hegemony, and you don't have to worry too much about The Emperor of Han. Cao Cao was very cunning, thinking that he should still try it, lure the snake out of the hole, and lure out all the forces that were loyal to the Han Room, even if he couldn't catch it all, he had a score in his heart.
Xu Tian's siege occurred in this context. Cao Cao borrowed the bow and arrow of Emperor Xian of Han and shot a prey, and the people only said that Tianzi shot it, and they all enthusiastically shouted to the emperor, "Long live". Cao Cao rode straight out and hid before the Son of Heaven to receive it. Everyone is lost.
Cao Cao's rebellious move, angry with Guan Yu, thought of killing Cao Cao in the past, Liu Bei hurriedly "shook his hand to send eyes, Guan Gong saw his brother like this, he did not dare to move", Liu Bei took the opportunity to shoot Cao Cao's ass, even if it was not exposed.
The above is the general process of Xu Tian's siege in the "Romance of the Three Kingdoms". So has there been such a thing in history? Of course there is, but it is a different look.
Second, the historical truth of Xu Tian's siege
According to the Chronicle of the Three Kingdoms, in the early years (after Cao Cao killed Lü Bu), Liu Bei hunted with Cao Gong (Cao Cao) in Xu (Du). During the hunt, the crowd dispersed, (Guan) Yu persuaded (Liu) to kill Gong (Cao Cao), and (Liu) did not obey.
The translation is: When Liu Bei was hunting with Cao Cao, Guan Yu persuaded Liu Bei to take the opportunity to kill Cao Cao, and Liu Bei said that he could not do so. Then, there was no more.
Compared with the "Romance of the Three Kingdoms", it is obvious that the truth of "Xu Tian Fighting the Siege" is a private play activity, and there is nothing to do with the Han Xian Emperor, and it has nothing to do with the struggle between Cao Cao and the Han Xian Emperor. Cao Cao also admired Liu Bei and regarded him as a guest of honor or a buddy.
The only thing that was the same was Guan Yu's move, he was riveted enough to kill Cao Cao. Why? Just because of a woman!
When Cao Cao attacked Lü Bu and besieged Xia Pi City, Guan Yu found Cao Cao and said: My wife has not yet given birth to a son for me, and there is a Lady Du in Xia Pi City, and her husband Qin Yilu does not want her, and marries another Han woman in Yuan Shu. Therefore, after breaking through Pi City, can you give Lady Du to me as a wife?
Cao Cao agreed. But Guan Yu knew who Cao Cao was, and reminded him many times. What happened to backfire, why did Guan Yu miss Lady Du so much? As a result, after attacking Picheng, Cao Cao found Lady Du for the first time, and she was indeed very beautiful. Cao Cao didn't say anything about what he wanted, so angry that Guan Yu couldn't do anything.
Therefore, in the "Romance of the Three Kingdoms", Guan Yu persuaded Liu Bei to kill Cao Cao while hunting with cao Cao. Of course, Liu Bei refused, and even most likely, reprimanded Guan Yu.
What would happen if Guan Yu really killed Cao Cao?
Although history does not allow for assumptions, in fact, it is a good way to deduce the results through assumptions, which has always been a good way to "read history wisely". Now let's assume that if Guan Yu really killed Cao Cao, what would be the consequences?
First of all, "Romance of the Three Kingdoms", when "Cao Cao went straight out on horseback, hiding before the Son of Heaven", if Guan Yu was angry at this moment and rushed forward desperately, whether he could kill Cao Cao was absolutely unknown.
One is that Xu Tian's siege is a well-planned plan set up by Cao Cao to lure the snake out of the hole. For this reason, Cao Cao was willing to take risks, which was also doomed, and there would be someone secretly protecting Cao Cao. If Guan Yu moved, the people who protected Cao Cao would definitely follow. And from the distance point of view, it is bound to be able to intercept Guan Yu.
It's a fight. We still assume that Ma Teng, Prince Fu, etc. (cloaked and commanded personnel), seeing Guan Yu's actions, also followed them to kill Cao Cao, then this turned into a big scuffle.
But the question is, what was the purpose of killing Cao Cao? Let Emperor Xian of Han regain power! Now that Cao Cao was closest to Emperor Xian of Han, how could he give Emperor Xian of Han any freedom? Therefore, as long as Guan Yu moved, Cao Cao's first action must be to draw out his sword and shout "protect the emperor" to come to The Han Xiandi. So Emperor Xian of Han became a hostage, and Guan Yu and others became assassins!
With Emperor Xian of Han as a hostage, even if Guan Yu and others can win the battle? Can he kill Cao Cao? The probability is too small. Not to mention, you can't win at all.
Therefore, in the "Romance of the Three Kingdoms", Liu Bei's words hid the truth, and afterwards Guan Yu asked Liu Bei why he stopped himself, and Liu Bei said: "Throwing rats and rats." and the emperor are only one horse's head, and his confidants, Zhou Hui, supports him; if my brother is angry for a moment, he acts lightly, and if things do not succeed, he will hurt the Son of Heaven, and the sin will sit on me and so on. ”
Killing Cao Cao is impossible.
And even if Guan Yu really killed Cao Cao, would Emperor Xian of Han be able to regain his freedom and take power? It was nothing more than another more violent civil unrest. Whether it was Cao Cao's forces or other forces, they would definitely come to compete for Emperor Xian of Han. Even if Liu Bei succeeded and held Emperor Xian of Han in his hands, with Liu Bei's ability and power at that time, it was absolutely impossible to keep Emperor Xian of Han.
It should be noted that at that time, Yuan Shao, Yuan Shu, Liu Biao, Sun Ce, etc. were still alive, which was the fuel saving lamp? Therefore, Cao Cao could not be killed. Liu Bei was very sober and realized that no one could afford the consequences of killing Cao Cao.
Speaking of the Romance of the Three Kingdoms, at that time, the relationship between Cao Cao and Emperor Xian of Han was still in the honeymoon period, and at most they began to be jealous of each other. And it is not so much that There was a contradiction between Cao Cao and Emperor Xian of Han, but rather a contradiction between Cao Cao and Dong Cheng. It can even be believed that Emperor Xiandi of Han deliberately let Cao Cao and Dong Zhuo fight, and he wanted to take advantage of the opportunity to reap the benefits and regain power.
In this case, there is still no reason to kill Cao Cao? Because Cao Cao is still a positive image.
Liu Beiruo really agreed with Guan Yu's opinion, or Guan Yu killed Cao Cao without Liu Bei's consent. The biggest probability is that Guan Yu is regarded as an outcast, and Liu Bei cannot keep it, so he will make the necessary division. Indication: Guan Yu was angry for a little Lady Du, which was really a death sentence.
Fourth, the general analysis
Therefore, Xu Tian's siege and Guan Yu's attempt to kill Cao Cao was a completely reckless and irresponsible move.
Although the Romance of the Three Kingdoms wanted to blacken Cao Cao in this way. However, after a circle of deduction, it was found that even if Cao Cao was blackened, he was still the most important force to ensure the continued existence of the Han Room - Cao Cao could not die!
Although Guan Yu changed his concept through the "Romance of the Three Kingdoms" and rose from a personal vendetta to a "national hatred", he still did not get rid of the shortcomings of "short-sightedness", which was a model with which he later scolded Sun Quan that "the tiger girl can marry a dog".
Liu Beixian was the beneficiary of Xu Tian's siege, and neither exposed, guan Yu's actions were looked at by Dong Cheng, Ma Teng, and others, and eventually Made Liu Bei a "personnel with a belt". Having the grip of "wearing the belt commandment", this is why later when Liu Bei counterattacked Cao Cao, he rightly and boldly said that he "bought the thief by the edict", in order to oppose Cao Cao's "blackmail of the heavenly son to order the princes".
This is actually the key to why xu tian is so handled in the "Romance of the Three Kingdoms", although it is an open contest between Cao Cao and Emperor Xian of Han, but the real beneficiary has secretly become Liu Bei! Therefore, I have to admire that Luo Guanzhong's changes are really wonderful and have far-reaching intentions.
