Give an example to show that Yao is a "discerning person"

Emperor Yao's visit to Xi 'an is the first story recorded in ancient books. Xu You of Chao Fu was a celebrity at that time. He advocates natural inaction, is not greedy for fame and fortune, insists on self-reliance, lives simply and has no desire for the world. When he learned that Emperor Yao was coming to visit him, he hid. I happened to meet Xiaogan and asked him where he was going. He said, "To escape from Emperor Yao". "Why?" Nie asked. Yao is a man of righteousness. I am afraid that he will be laughed at by the whole world and that someone will eat people in the future. " Ordinary people? It is not difficult to win them over. Love them and they will be close to you; Give them benefits and they will be attracted to you; Praise them and they will be diligent. Do what they hate, and they will run away. Caring for and benefiting the people is based on benevolence and righteousness, and those who sincerely practice benevolence and righteousness benefit more. This kind of benevolent behavior can not only be implemented, but also become a tool of hypocrisy. This kind of thing that wants to make the world profitable with one person's decision is just one size fits all. Yao only knows that sages can benefit the world, but he doesn't know that sages can harm the world. Only people who don't value sages know this truth. After a while, Emperor Yao visited Xu You and worshipped Xu You in Peize. Yao said to him, "When the sun came out, the torch was still there. Isn't it unnecessary to let it shine in the sunlight that illuminates the universe? Isn't it futile to water the garden after the heavy rain? As the son of heaven, I am ashamed that it is inappropriate to occupy the throne. Please allow me to entrust the world to Yu Xiansheng and the world will be peaceful. " Xu You said to Emperor Yao, "You have ruled the world for a long time. Now that the world has been ruled, let me be the ready-made son of heaven instead of you. Do I want to be famous? "The name is a real subordinate, and I'm not interested in that fake name. Even if the wren nests in the deep forest, it only takes one; Even if the mole ran to the Yellow River to drink water, it would be enough to drink into his stomach. Go home. The son of heaven is useless to me. Who's the chef? Sacrifice will not replace cooking without sacrifice. " So Xu You went to Mount Ji, where he plowed and ate. He is very happy and never covets the pity of life. Legend has it that Yao gave up his position in the world and thought it was shameful. He went to the river to wash his ears, and later he was named ear washing river. Someone took a cow to the river to drink water. When Xu You washed his ears, he asked why, and said, "You washed your ears and made the water here dirty. I don't want my cows to drink this sewage. " Take the cows to the upper reaches of the river to drink water. Emperor Yao once visited a man named Zizhou Magistrate. After consulting him, he felt that this man could support the world and let Zizhou support his father. Zizhou's father replied, "It's okay to give me the world, but it's a pity that I'm suffering from depression and I'm preparing to treat it well. This is unacceptable." Emperor Yao is reluctant, but he respects him very much.
