Yong's "Cao Qin Hejian Zage Ji": I heard that it was in Yao Tongqing Festival. Yao's ambition is to send messengers to Fuxi Zen as the emperor. So Xu You sighed: "A person's ambition is as indestructible as a rock. Take the mountain and drink the river, so cultivate one's morality, not for the position of Lu; Put it down and travel well, so that you are not afraid of yourself, not because you are greedy for the world. The man returned the book and played a watch to Yao. "。 Yao knew it was impossible to move, and it was gone. So Xu You took the messenger's words as a bad thing, but washed his ears by the river. Fan Jian saw Fang washing his ears and asked him,' What happened to his ears?' You said,' There is no dirt, and you smell bad words.' Jane said,' What kind of speakers?' Yu Yue; Yao hired me as the emperor. Jian said:' What's wrong with your position? Yu yue:' I aim at Qingyun, why am I not as good as commander Kyushu? So Fan Jian drank the cow, listened to his words and left, ashamed to drink it to filth. ◇ Huangfu Mi's Gao Shi Biography of Chao Fu said that Xu You told Chao Fu the location of Yao Chan. "Chao Fu said,' If it weren't for my friend, why didn't you hide the light?' Fall on leave. From disappointment to complacency, it is to wash his ears and wipe his eyes with clear water. "Gao Chuan Xu Shi Tour" says: "Yao won the world ... because he didn't want to listen, he washed his ears at Ying's seaside, and his friend Chao Fu led the calf to drink, but when he saw it, he washed his ears ... Chao Fu said,' If Zi is in a deep valley on the high shore, no one can see him, so he wants to hear his name and pollute the mouth of my calf!' Bring the calf to drink. "There are different opinions. There is no basis for saying that Chao Fu washes his ears. Qiao Zhou's Textual Research on Ancient History says that there is a saying that "the nest washes the ears" and "Chao Fu washes the ears", or it is for this reason.
