"The Analects of Confucius Lutz": "Gentlemen are harmonious but different, and villains are not harmonious." A gentleman can maintain a harmonious relationship with the people around him, but he must think independently in everything and never want to blindly agree with others. The villain has no opinion of his own, just wants to be consistent with others, and does not talk about principles, but he can't maintain a harmonious relationship with others. This is dealing with people. In fact, on almost all issues, the difference between "harmony without difference" and "harmony without difference" can be reflected. "Harmony without difference" shows the profound philosophy and high wisdom of Confucius' thought.
