Later it came to mean a state of governance in which there are good social relations of coexistence based on respect for differences and diversity. In such a society, all people give free rein to their talent and find their proper place to live together in harmony, order and health.

It now generally refers to the harmonious, peaceful, and amicable relationship between people, between groups, and between countries. Harmony represents the Chinese cultural value of opposing violence and conflicts and cherishing peace and order.
