Yang Zhu, a native of Wei during the Warring States Period, was named Ziju, also known as Yang Zi. His famous doctrine is egoism, and his famous saying is: Pluck a hair to benefit the world without doing anything. But his "ignoring the small details" theory is not without merit.
Yang Zhu once said to the King of Liang: "Governing the world is easy."
Liang Wudao: "Mr. Yang, you can't manage a wife and a concubine. You have three acres of land." You are not good at this, but you say that governing the world is easy. How can I believe it?"
Liang Gong's words are very reasonable. He compared Yang Zhu's family management with his country's governance to prove that Yang Zhu's words are unreliable? .
Yang Zhu said: "Have your Majesty seen the sheep? More than a hundred sheep gathered together. The shepherd boy only followed with a long whip, but he commanded it freely. If you want the sheep to go east, go east, and if you want the sheep to go east, go east. West is west. If Yao was asked to lead a sheep and Shun was asked to carry a stick on his shoulders, the world would be in chaos. I heard that fish that are big enough to swallow a boat will not swim into shallow valleys; those that can fly high Big Bird will not rest in a dirty place. Why? It is because of its great ambition. The rhythm of Huang Zhongdalu cannot be matched with the complex rhythm. So it is very monotonous. , Don’t worry about small details; if you want to achieve great things, you can’t care about small things.”
Yang Zhu used analogical reasoning to express his view that “governing the country is easy”. Rhetorically speaking, the logic of its application ( Analogy) is persuasive, and because of this, Yang Zhu's argument has become a famous saying that has been passed down to this day.
