Is it Cao Cao's original intention that Yang Xiu said "one mouthful and one crisp" in the "one crisp" incident?
If it is Cao Cao's original intention, it is because Cao Cao often likes to do something inexplicable to show his extraordinary intelligence. For example, write a word "live" on the door, indicating that the door is too wide; For example, first declare that you want to kill someone in your dream, and then deliberately kill the chamberlain to prove this point. The above two things are similar to the "crisp bite" incident, so this "crisp bite" incident may be caused by Cao Cao on purpose.
The reason why Cao Cao did these things is to let everyone guess his thoughts and be more awed by him. Is Yang Xiu really the only one who can read Cao Cao's mind? I don't think so. There are still many smart people under Cao Cao. The reason why everyone kept silent was because they obviously understood Cao Cao's mind and didn't expose it. However, Yang Xiu must jump out and expose this matter, forget to repair the door and eat crispy food. Exposing the murder in the dream has violated Cao Cao's taboo and said, "The Prime Minister is not in the dream, you are in the dream." This is simply a challenge to Cao Cao's endurance limit, and it is clearly a death wish.
If it is not Cao Cao's intention, it makes sense. Speaking of the door repair incident, Cao Cao was very happy to see that the back door was small, and asked who really understood his mind; In the "Bite Crisp" incident, Cao Cao only asked Yang Xiu why he shared this shortcake, but didn't ask who guessed his idea. Moreover, in the event of repairing the door, Yang Xiu also secretly helped Cao Cao, so Cao Cao was just "jealous" and jealous of Yang Xiu's cleverness; In the "crisp" incident, Cao Cao listened to Yang Xiu's explanation, but he hated him. This shows that Cao Cao probably wrote these three words unintentionally, and Yang Xiu's explanation, in Cao Cao's view, is likely to be sophistry. Moreover, Cao Cao, as the prime minister, will not be so bored because of his busy schedule. He specially wrote three words to test his IQ.
In fact, Yang Xiu tried his best to show his intelligence in Cao Cao's position. For example, in order to cope with Cao Cao's questions, he often thinks about what Cao Cao will ask in advance, and then prepares the answers and waits for Cao Cao's questions. Once he prepared the answers to several questions in advance and then went out. When Cao Cao asked questions, his men handed in the answers. It happened that a gust of wind blew over and messed up the answer sheets. As a result, the order of the answers was completely wrong and was discovered by Cao Cao. Cao Cao called Yang Xiu to ask, only to know that this kind of thing has happened many times. Yang Xiu may still be complacent, but what will Cao Cao think? As a subordinate, Yang Xiu can guess the thoughts of his superiors, and you can guess them every time. What do you want? Even a magnanimous monarch under the imperial power will certainly feel uncomfortable, not to mention the treacherous Cao Cao. In doing so, Yang Xiu is really challenging the limits and digging his own grave.
Moreover, Yang Xiu not only showed off his cleverness, but also got involved in the struggle between Xelloss and Cao Zhi, and stood on Cao Zhi's side. As mentioned above, Yang Xiu prepared his own answer for Cao Cao, and he also taught this method to Cao Zhi. Later, it was exposed by Cao Pi. Of course, Cao Cao was furious and didn't even like Cao Zhi. He also reported to Cao Cao that Cao Pi secretly knew Wu, because what Cao Cao hated most was the collusion between his son and his ministers. As a result, Wu's trick bankrupt his plan. In Cao Cao's view, it was Yang Xiu who helped Cao Zhi plot against Cao Pi, and the alliance between Yang Xiu and Cao Zhi was also a plot to seize power. For Cao Cao, who has a particularly strong desire for power, the most taboo is that his men make a fuss about power. It can be said that Cao Cao had already had the idea of killing Yang Xiu.
By the time Liu Bei was at loggerheads in Hanzhong, Cao Cao had decided to make xelloss his successor, and had long wanted to kill Yang Xiu, the "backbone" of the "Cao Zhi Group", paving the way for xelloss's smooth succession. Just as Yang Xiu jumped out to show off his cleverness, he said "chicken ribs" was an order to withdraw troops. Maybe Cao Cao was in a dilemma at that time, but Yang exposed him, so he had to bite the bullet and continue to fight with Liu Beidou. At the same time, Cao Cao also found a reasonable excuse to kill Yang Xiu: interfering in military action. Therefore, Yang Xiu can't run away this time, and he will die if he dies.
In the final analysis, Yang Xiuzhi's death was really because he was full of cleverness, not great wisdom. He doesn't know how to get along with such a treacherous man as Cao Cao. He doesn't know that blindly showing off his knowledge is stimulating Cao Cao, and being involved in the battle for official positions is accelerating his approach to the gate of hell. Look at Jia Xu. Wisdom is not under Yang Xiu at all, but it is all great wisdom. He only gives advice when Cao Cao needs it. He usually stays indoors and doesn't associate with anyone. Only in this way can Cao Cai rest assured, so Jia Xu finally came to a good end.
