One day, he said to his courtier, "it is said in the photo book that the longer a person's" middle person "under his nose, the longer his life. One inch in a person can live a hundred years. I wonder if it's true or not? " Dongfang Shuo felt that the emperor's dream of immortality was ridiculous. The emperor saw that Dongfang Shuo seemed to be sarcastic, and his face was displeased. He said, "how dare you laugh at me?" Dongfang Shuo took off his hat and said respectfully, "how dare I laugh at the emperor? I'm laughing. Peng Zu's face is so ugly. " Emperor Hanwu asked, "why do you laugh at Pengzu?" Dongfang Shuo said: "it is said that Peng Zu lived 800 years. If the Emperor just said that" people "should be eight inches long, then isn't his face as long as Zhang?" The emperor of Han also laughed. Dongfang Shuo criticized Emperor Hanwu's ignorance and satirized Emperor Hanwu's absurdity by ridiculing Peng Zu. However, Emperor Wu of the Han Dynasty accepted Dongfang Shuo's criticism.
