"Chu Er Fan Er" originally meant "treat others as you would be treated yourself," originating from Mencius, King Hui of Liang, Part II: "What comes from you returns to you." Later, the meaning of the term shifted to describe a person whose words and actions are contradictory and capricious, lacking credibility. This idiom carries a strong derogatory connotation and is often used to criticize those who break promises and arbitrarily change their positions. It is commonly applied in social, commercial, or political contexts, emphasizing the importance of integrity. Culturally, it reflects the Confucian emphasis on "trustworthiness," holding that a person cannot stand without credibility. Its deeper meaning serves as a warning for people to match their words with their actions, or else they will lose the trust of others. Emotionally, it expresses condemnation and dissatisfaction toward dishonest behavior.
