King Huai of Chu was coaxed by Zhang Yi to be overjoyed, believing that he had obtained the land of Shangyu without a single soldier, and he did not blame the king of Chu Huai for being excited, because the land of Shangyu was for the Chu state, just like the sixteen states of Youyun for the Northern Song Dynasty. If King Huai of Chu could really accomplish such a feat during his term of office, he would really be glorious and mighty. This showed that the bait thrown by Zhang Yi was too fragrant, and it just hit the pain point of the Chu people, and immediately brought the King of Chu Huai into his own trap.
King Huai of Chu
King Huai of Chu did three things at the same time, one was to ask Zhang Yi to serve as the premier of the State of Chu and give him various rewards; the second was to break diplomatic relations with the State of Qi and no longer receive emissaries from the State of Qi; and the third sent a general to follow Zhang Yi to the State of Qin to handle the handover of land.
After Zhang Yi returned to the Qin Kingdom, he should have hurriedly handed over the land, but he did not, he pretended to fall off the car, fell and was injured, and rested for 3 months in a row, not going to the office of the court. It is said that after king Huai of Chu heard about it, he should be able to think that Zhang Yi was playing a rogue and that he had been deceived. However, he did not expect that King Huai of Chu was actually very cultivated in character. Things did not work well, first find the reason from myself, probably I broke off diplomatic relations with Qi Guo, the break was not thorough enough, let Zhang Yi pick the reason, right? It's like a relationship, how to break up with the ex to make the incumbent satisfied.
Simply blacking out the ex is clearly not enough. King Huai of Chu sent a warrior named Song Yi, borrowing the Song Kingdom Rune Festival, to come to King Xuan of Qi and scold him, clamoring to break up. Why send warriors instead of messengers? Because it takes too much courage to do such a thing, it is difficult to ensure that King Xuan of Qi will not commit murder on the spot. Why borrow the Song Dynasty Runes? Because the two countries had severed diplomatic relations, the emissaries of the State of Chu could not enter the gates of the State of Qi. King Xuan of Qi was scolded for no reason, his anger exploded, and he had no illusions about the State of Chu, and immediately went to establish diplomatic relations with the State of Qin.
Zhang Yi was waiting for this matter, watching the Chu State and the Qi State completely break with it, there was no longer any possibility of returning to good things. And the State of Qi is allied with the State of Qin, although the State of Qin is not good, and then move the brains of the State of Qi, but you can change the strategy and unite with the State of Qi to fight the idea of the State of Chu, the situation is better than the original expectation of the joint Chu attack on Qi. Zhang Yi was "injured" this time, went to the court office, and entertained the envoys of the Chu state and said, "Why haven't you done a good job in the land transfer procedures?" No, from here to here, 6 miles long, 6 miles wide, take it. ”
The land area has shrunk by 10,000 times in the blink of an eye, which is really a naked hooligan. Of course, the emissary did not do it, and hummed back to the country to report, this time it was the turn of the King of Chu Huai to explode, and he had to fight with the Qin State to the death.
Today, when we stand in God's perspective, of course, we will feel that King Chu Huai is stupid and arrogant, and will only drill into Zhang Yi's trap. But what can we do if we put ourselves in the shoes of whether the deal is genuine or not?
This is equivalent to the commodity trading proposal, saying that as long as one hand pays for the delivery of the goods, the money and goods are clear, it seems that it can be simply assured, but the payment and delivery may really be completed at the same time after all. If Chen Yun's opinion is taken, the Yang and Yin sides of the State of Qi are violated, and then diplomatic relations with the State of Qi are severed after receiving the land of Shangyu, then the problem is that if the State of Qin wants to make this deal with sincerity, it will also worry that the State of Chu will not be honest, and it must first see that the State of Chu has broken off diplomatic relations with the State of Qi, and then it is willing to offer land. Therefore, the Chu state side is "if you don't cut the land, I will continue to hand over", and the Qin side is "if you keep handing over, I will not cut the land", and the transaction is doomed to an impasse.
Today, it is easier for us to solve this kind of problem, because game theory gives a very classic solution to the problem, and the simple summary method is: to break the whole into zero.
Specific to the King of Chu Huai, the land of injury is 600 miles, and it is not required to be cut once, and it can be divided in stages and batches. In contrast, on the side of the Chu State and the State of Qi, the same as the severance of diplomatic relations with the State of Qi, can be divided into phases and batches, such as first raising tariffs on specific commodities imported from the State of Qi, qin and Chu so that you take one step, I take one step, you pause at which step, delay, I will pause and delay at which step accordingly, and I can also give the corresponding punishment according to the agreement.
Now you may feel that the king of Chu Huai has not learned game theory, and the way of thinking is too primitive, which is deceived by Zhang Yi, but in human history, Zhang Yi's deception has always deceived more than one King of Chu Huai. Specific to the case of King Huai of Chu, the State of Qin played hooligans without any excuses, and naked hooligans played hooligans. The State of Chu was bullied too fiercely by the State of Qin in the era of King Huai of Chu, so until Qin Shi Huang unified the Six Kingdoms, the will to resist was particularly strong, resulting in the proverb "Although Chu has three households, the death of Qin will be Chu". So if King Huai of Chu used game theory to negotiate with Zhang Yi when negotiating with Zhang Yi, what would be the difference in the outcome?
