Be harmonious but different, get along harmoniously, but do not agree casually. From "The Analects of Confucius·Zilu": "Gentlemen are harmonious but not in harmony; villains are in harmony but not in harmony." Same, just agree with each other

He means harmony; Tong means agree with each other. Get along harmoniously, but don't go along easily. [1]

Confucius, the founder of Confucianism, has a famous saying: "Gentlemen are harmonious but not in harmony; villains are in harmony but not in harmony." It means that in terms of how to behave in the world, the correct way should be to refuse to agree and to argue with each other. Consciousness is achieved in the defense. In ancient China, "harmony without difference" was also an important principle in dealing with the relationship between different academic schools of thought and different cultures. It was the driving force, approach and basic law for the development of academic culture.

Example: He is human but rude, and this one is harmonious but different.
