Story:
During the Spring and Autumn period, Confucius took his students on an outing.
Zilu, Zeng Xi, Ran You, and Gongxi Hua accompanied Confucius while they chatted idly.
Confucius sighed and said to them, "Because I am slightly older than you, no one will employ me. You often say, 'No one understands me!' Now, if someone truly understood you and asked you to do something, what would you do?"
