A Taoist teacher taught his students: "As long as you carefully understand a word or two of Confucius' words, you will benefit a lot throughout your life." A young student came forward and said respectfully. Li: "The student carefully copied two sentences from Confucius and understood them very kindly. He felt that his heart was broadened and his body was fat." The teacher asked which two sentences they were, and replied: "You never tire of fine food, and you never tire of fine food." "(The more beautiful the rice, the better, and the more finely cut the meat, the better.)
