When Chen Chengzi assassinated Duke Chien, Confucius cleansed himself according to ritual and went to court. He reported to Duke Ai, saying, “Chen Chengzi has killed his ruler. I encourage you to punish him.”
Duke Ai replied, “Report this to the Three Families.”
Confucius said, “It’s only because I have an official rank that I felt duty-bound to make this report. And yet Duke Ai tells me to report it to the Three Families?”
Confucius then reported the matter to the Three Families, but they refused to do anything about it.
Confucius repeated, “It’s only because I have an official rank that I felt duty-bound to make this report.”
