In the early Spring and Autumn Period, vassal states merged with each other. Jin, located in the Central Plains, constantly annexed and conquered small countries in this melee, and its strength rose rapidly. During the reign, he planned to annex two small countries in the south, Guo and Guo Yu. However, it is not easy for Kim to achieve this goal smoothly. Although Guo and Yu are sparsely populated and weak in national strength, they have formed an alliance with the same surname. King went to war with any country in order to compete with teachers from both countries. How to disintegrate the alliance between Guo and Yu and avoid falling into two-front operations is the first problem to be solved in the military action of annexing the two countries. Finally, Xun, the doctor of the state of Jin, came up with a brilliant plan to kill two birds with one stone: bribing with rich gifts and precious treasures, breaking up the alliance between Guo and Yu, and attacking Guo by false means, waiting to be deceived by Yu and defeated by Guo. After listening to Xun's contribution, I think this plan is very good, but I still have some concerns. First of all, some of them are unwilling to give up their treasures. Second, they are afraid that the honest minister Yugong will expose the intention of the State of Jin. In view of the indecision, Xun made a proper explanation one by one, pointing out that sending the treasure to Yuzhou is tantamount to temporarily storing it there and getting it back sooner or later; As for Gong, although he has some abilities, his opinions may not be adopted, so he is not afraid. These words dispelled the last worry of offering the public, and he decided to act according to Xun's counsel. Soon, Xun came to Yuzhou with rare treasures such as good horses and jewels. When you get there, you will be satisfied, put forward the treasure, and formally ask to attack Guo. Gong was greedy for profits and accepted a good horse and jade, but he did not dare to offend the State of Jin easily, so he promised the State of Jin to conquer the Guo family through Yuzhou and expressed his willingness to send troops to help the State of Jin fight. Gong felt wrong and tried to dissuade him, but he didn't listen at all. He just went his own way and forced himself into the golden trap. In the summer of 658 BC, the doctors of the State of Jin, Rick and Xun, led the army of the State of Jin to attack the State of Guo through the ground. Gong Yuxin kept his promise, sent troops to join forces with Xu Jinguo, and then cooperated with Xu Jinguo to launch military operations. With the active cooperation of 8 jin j, Guo Xiayang was quickly captured and the strategic position between Guo Yu was controlled in one fell swoop. Through this incident, Guo further clarified the real situation, which created conditions for the next action. Three years later, Jin Xiangong made another request to cut grass in Yuzhou. At this time, Yu Gong saw the sinister intention behind the "false road". It is pointed out that "if the country dies, the danger will die with it." Someone warned that "you can't start, you can't play." Trying to dissuade Yu from going to Jin with the benefit of "cohabitation" between Guo and Yu. However, he is greedy, so he doesn't accept any advice at all. Instead, I take Kim as my surname and use the excuse that I won't hurt myself. He agreed to the request of the state of Jin. Seeing that his country was dying, Gong led his people to flee the country. This time, Jin Xiangong personally led the army to attack Guo Si through Yuzhou, which was far more powerful than last time, so he was determined to win. 8 jin j made rapid progress, and soon arrived at the gates of Yang, besieged on all sides. Guo's country was weak and helpless, and a few months later, it was destroyed by the Jin army. Qi Huangong fled to the capital. Jin immediately returned home in triumph. When it was stationed in danger, it jumped in, launched a surprise attack, occupied Yugong, easily destroyed Yuzhou, and finally achieved the goal of annexing the two countries. 8 Jin Jun's victory lies in the ability and cleverness of "hiding if you win".

Secondly, its supreme ruler was incompetent and greedy for temporary benefits, which destroyed the strategic alliance with Guo. And whitewash peace, refuse to be taught, and finally, ask for it. Third, in connection with the above two points, after the destruction of Guo by the State of Jin, the State of Yu was unaware of the new strategic trend, so that it was too late to resist when the State of Jin launched a surprise attack and was helpless. The battle of false extinction of Taoism embodies the rich and profound art of military struggle, so it has been widely valued by military strategists in past dynasties. The famous military work "Thirty-six Plans" also defines it as a plan, which summarizes such an important law in military struggle: war instructors deliberately cover up their true intentions, take advantage of the enemy's greed and timidity, and attack the third party to infiltrate their own forces and control each other. Once the time is ripe, attack at lightning speed, destroy or subdue your opponent in one fell swoop, and achieve the goal of killing two birds with one stone. Historically, false cutting is often imitated by some people and becomes a common strategy in the process of strength and weakness, devouring small things. For example, in 963 AD, Zhao Kuangyin in the Northern Song Dynasty "forged Jinghu Lake", captured Jinghu Lake, and eliminated the separatist forces in Nanping and Wuping, which is a remarkable example. Of course, another truth reflected in this war is that the lips are dead and the teeth are cold, which also provides useful enlightenment for future generations to unite the weak countries against the strong ones.
