It is said that in the Eastern Zhou Dynasty, Su Qin of Luoyang worshipped Guiguzi as his teacher. A few years later, he sold his property and traveled around the world, explaining his political views to kings of various countries, hoping to show his political ambitions, but he was not appreciated. At this time, Su Qin was penniless and returned to Luoyang, but his family looked down on him, and Su Qin began to study hard again. He tied up his hair and hung it on the beam, and later successfully unified the six countries. This is the origin of cantilever beam [9]. Later, there was a famous sentence in the three-character classic, "The head hangs on the beam, and the awl stings the stock", which came from this.

Change from arrogance to respect: After studying hard, Su Qin began his second trip around the world. This time, it finally persuaded Qi, Chu, Yan, Han, Zhao and Wei to unite against Qin, and was sealed as a "longitudinal contract" with the national seal of the six countries. At this time, Su Qin returned home dressed in golden clothes, and his relatives changed their old attitude, all of them bowed down to give thanks, and his wife changed her attitude towards him. Su Qin can't help but sigh: "Life is alive, and status and wealth can't be ignored." . The allusion of "change from arrogance to respect" comes from this.

Paper in Luoyang is expensive: After the publication of Sandu Fu by Zuo Si, a famous writer in the Western Jin Dynasty, it became popular in Luoyang, and the price of paper in Luoyang market became expensive. "Luoyang paper is expensive" has become a famous allusion.

Pick the fat and choose the thin: Liu Xiu, Emperor Guangwu of the Eastern Han Dynasty, founded the first aristocratic university-Taixue in Luoyang. A teacher named Zhen Mingyu works in imperial academy. One year on the thirtieth day of the twelfth lunar month, Liu Xiu wrote a letter to the teachers in imperial academy, asking them to send each one a sheep. When the sheep arrived at the imperial academy compound, they found that each sheep was different in size and fat. After discussion for a long time, there was no acceptable distribution method. At this moment, Zhen Yu stood up and said, "We are all teachers, all teachers. We can't haggle over every ounce and pick and choose! " Then he picked out the smallest and thinnest one from the flock and led it. This time, everyone stopped arguing and soon finished dividing the sheep. From then on, the story of leaving the sheep spread. People in Luoyang praised Zhen Yu and nicknamed him "Dr. Thin Sheep". Since then, the idiom "picky" has spread.

Don't eat: During the attack, 800 vassals arrived, crossed the river, and fought the army in Mu Ye. Zhou Wang was defeated by the slave rebellion, and later set himself on fire in Lutai, and the Shang Dynasty perished. Boyi and Shu Qi were ashamed of eating, and lived in seclusion in shouyangshan to pick Wei to eat. A woman said, "If you don't eat it, it's also Zhou's vegetation." They died of hunger strike in shame and indignation, and were buried in shouyangshan.

Debt-ridden: Starting with the Preface to Hanshu. In the fifty-sixth year of Zhou Nanwang (the first 259 years), in order to unify Chu and Wei, he attacked Handan, the capital of Zhao, which was besieged by Qin, and borrowed money from local rich merchants. In the end, only Chu and Yan's army arrived, and the alliance failed. Later, the local rich man asked Zhou Nanwang for debts, so he had to hide in a high platform in the palace. Later, people called this platform a debt avoidance platform, so the idiom "debt is high" came into being.
