Meng Yizi (孟懿子) is said to have been one of two young nobles from the state of Lu who were entrusted by their father to Confucius for tutoring when he starting out as a teacher. Meng subsequently rose to become head of the Mengsun (孟孙) clan, one of the notorious Three Families that were the real power in Lu. In Chapter V of Book 2, Confucius criticizes him obliquely for holding over-elaborate ritual ceremonies that violated the conventions of the rites.
Appearances in the Analects of Confucius
Book 2, Chapter V
Meng Yizi asked Confucius about filial piety. Confucius said: “Never disobey.” While Fan Chi was driving him in his chariot, Confucius told him: “Meng Yizi asked me about filial piety and I replied: ‘Never disobey.’” Fan Chi asked: “What does that mean?” Confucius replied: “When your parents are alive, serve them according to the rites. When they die, bury them according to the rites, and make sacrifices to them according to the rites.”
