Story:
During the Spring and Autumn period, Confucius traveled with his students through various states to give lectures. When they arrived at Ye邑 in the state of Chu, Duke Ye (Shen Zhuliang) hosted him.
Duke Ye, not knowing much about Confucius, quietly asked Zilu about him. Zilu was momentarily at a loss for how to respond.
Later, when Confucius learned of this, he told Zilu that next time he should say: "He is a person who works so hard that he forgets to eat, finds joy in forgetting his worries, and does not realize old age is approaching."
