The unity of theory and practice. Confucius's humanistic ethics is essentially a science of education. The so-called education, first of all, pays attention to the rational understanding of ethics and morals. Therefore, Confucius's ethical thoughts emphasize the importance of "knowledge", such as knowing etiquette, knowing benevolence, knowing life, knowing prescriptions, knowing virtues, knowing people, knowing destiny, etc. But on the other hand, he also pays attention to practice, so he said, "Those who know are not as good as those who are good at it, and those who are good at it are not as good as those who are happy." More importantly, for ethics and morality, actions and actions are connected and inseparable, and they are unified in the process of practicing etiquette.
