There is an idiom in the textbooks that students learn now called "self-recommendation", and the meaning of this idiom is to recommend yourself bravely and confidently, and to recommend yourself to take a job.
Mao Sui in the idiom story was originally just a very ordinary doorman under the hands of the Zhao State Plain King during the Warring States period, and was not favored among many doormen. However, he understood his own ability, had the courage and witty conversation skills that others did not have, so he recommended himself to take on the heavy responsibility of diplomacy with the Chu state. The final outcome was a perfect agreement between the two countries, and Mao Sui was also famous for this matter, which also made a rope for the friendly relations between the Later Chu State and the Zhao State, and finally the cooperation between the two countries won a good ending.

It was precisely because of this mission that Mao Sui later received praise from others, saying that he had such praise as "three inches of uncorrupted tongue, stronger than a million masters". Later, when he returned to the Zhao Kingdom, Pingyuan Jun remembered that Pingyuan Jun, who had previously looked down on Mao Sui, had always looked down on Mao Sui and regretted what he had done, because he did not expect Mao Sui's diplomatic ability to be so strong.
Later, Pingyuan Jun called Mao Sui Mr. and had various respects for him, which showed that Mao Sui's position in Pingyuan Jun's heart was extraordinary. According to general, Mao Sui's later fate should be like a fish, but his final ending was unexpected, because Mao Sui actually committed suicide by swinging his sword in the second year after the success of his self-recommendation.
In the second year after Mao Sui's successful self-nomination, when the State of Yan took advantage of the fact that the State of Zhao had just experienced a great war and suffered a lot of losses, so it needed to rest and rest, so it took advantage of the danger of the people and sent an army to attack the State of Zhao. Because there was no preparation, Zhao Guo panicked for a while, and all the people did not know how to deal with this sudden battle, and who would lead the army to meet the battle.
At this time, Pingyuan Jun thought of Mao Sui, who was socially successful at that time, and Mao Sui was heroic and cool, and Ping Yuanjun also felt as if he saw hope, and felt that Mao Sui could definitely rescue Zhao Guo in danger again like a year ago. So he confidently promoted Mao Sui to the position of general and led the troops out on the expedition.
However, Mao Sui only possessed very strong diplomatic capabilities, did not have a very in-depth study of the military aspect, and did not have the ability to lead troops to fight. And Mao Sui himself did not seem to know this, and he did not resign from Ping Yuanjun's arrangement, and walked to the battlefield with the same confidence as before. He had thought that with his own wisdom, leading troops to war must be as simple as diplomacy. However, fighting a war is not the dead knowledge in books, the situation faced on the battlefield is changeable, and many generals become generals because they have experienced hundreds of battles, not only their minds and temperament, but actual combat experience is actually more important than everything.
Therefore, in the Battle of Qamdo, the Zhao army lost in a very tragic way, and Mao Sui, as the leader of the army, saw such a tragic situation on the battlefield for a while and felt that he had no face to go back to face Pingyuan Jun, so he directly swung his sword and killed himself to apologize.
Only a year had passed, and Mao Sui, who had been praised by everyone for his outstanding diplomatic ability, fell into the abyss in an instant, and it was really regrettable that he had lost his life because of this matter.
Mao Sui's story is more to tell us that a person should clearly understand himself, and it is good to have self-confidence, but he should put himself in the right position and understand what he is suitable for and what is not suitable for what he is not suitable for. It is not that if you do a successful thing, it means that you are all-powerful, after all, everyone is not perfect, and there are areas that are good at and areas that are not good at.
The so-called face to face themselves, you need to understand both what you are good at, but also to understand what you are not good at, this is a science and a thought, many people may have to spend a lifetime can not learn.
And Mao Sui may have suddenly understood this truth before he died, but he really did not have the confidence to go back and bear the next consequences, so he simply died for liberation.
Self-recommendation has always been used as a positive word, which is a symbol of self-confidence and understanding of one's own abilities. However, in the end, the end of Mao Sui is lamentable, but it is precisely caused by the incomplete examination of his own ability. If he had the courage to introduce himself at that time, he had pushed off Ping Yuanjun's recommendation and explained the reason, perhaps the final ending would be rewritten, and Zhao Guo's fate would not stop there.
After all, each tool has its own uses, just like a kitchen knife is used to cut vegetables but cannot be used to wash clothes, and the mallet cannot be used to cut vegetables for cooking, but to hammer clothes. If Mao Sui had not died, and then continued to do things with his diplomatic ability, he would have made a lot of contributions to the Zhao State.
