It should be that the food is tasteless, and it is a pity to throw it away. The source is "Three Kingdoms·Wei Zhi·Wudi Ji" Pei Songzhi's annotation quoted from "Jiuzhou Spring and Autumn": "Husband's chicken ribs, it is a pity to throw them away, and there is nothing to gain from eating them. Hanzhong, I know the king wants to return." Allusion: Cao Cao and Liu Bei faced each other in Hanzhong, and the two armies were at a stalemate. Cao Cao was worried when he saw that it had been raining for days, that his food and grass were running out, and that he could not win. At this time, the soldiers came to ask for the order for the night. Cao Cao was looking blankly at the chicken ribs in the bowl, thinking about how to advance or retreat, and he casually replied: Chicken ribs! When the command "chicken ribs" was sent to the chief secretary Yang Xiu, the guy was so smart that he encouraged the soldiers to pack up and prepare to withdraw. The soldiers asked why. Yang Xiu said: It is useless to throw away chicken ribs, and it is tasteless to eat. The Prime Minister cannot win today if he advances, for fear of being laughed at, he will order his troops to retreat tomorrow. So everyone believed it. When Cao Cao found out about this, he beheaded Yang Xiu in the name of deceiving the troops. This is the allusion about tasteless food. This is from "The Romance of the Three Kingdoms". The original words should be: "What you eat has no meat, but what you throw away has flavor." Story Everyone who has read "The Romance of the Three Kingdoms" knows the causes and consequences of Yang Xiu being killed by Cao Cao. Yang Xiucai was quick in thinking, extremely intelligent, and a man of discerning tongue. He relied on his talent to be open-minded, and was appreciated and valued by Cao Cao. He became an important minister of Prime Minister Cao Cao. After the Kuo Men incident, a box of cakes, Cao Cao's murder in his dream, and Wu Zhi's incident, Cao Cao had a secret grudge against Yang Xiu and was secretly wary. Later, Yang Xiu secretly intervened in the dethronement of the crown prince, which caused great dissatisfaction among Cao Cao. and jealousy. During the Hanzhong War, Cao Cao killed Yang Xiu on the charge of "tasteless" and buried him generously. He also rewarded him with many items to express his comfort to his relatives. Yang Xiu's death was described in detail and vividly in Luo Guanzhong's "The Romance of the Three Kingdoms". It makes people unable to see the clues of Cao Cao's murder of Yang Xiu. Instead, he dealt with the "tasteless incident" impartially, killed Yang Xiu according to law, strictly enforced military discipline, and did everything right. It was seamless, and it eliminated a major hidden danger in my heart and relieved my worries. Yang Xiu, as a counselor in the feudal era, can be called a typical figure in ancient China. His talent and knowledge are outstanding. He is also quite accurate, quick and agile in speculating, analyzing, judging and predicting the psychological activities of Prime Minister Cao Cao, and he has a certain degree of foresight. It was precisely because of the accuracy of this advance prediction that Yang Xiu lost his life. Although Yang Xiu had a clear understanding of Cao Cao's conflicting and hesitant mentality before he retreated, as a staff member under Cao Cao for many years, he had enough understanding of Cao Cao's suspicious, violent and cruel character. He mistakenly believed that Cao Cao would not kill him for this, so he dared to openly say in the army that Cao Cao would withdraw his troops, and asked the soldiers to pack up, salute, and prepare to return to the court. This is a typical example of cleverness being misled by cleverness.
