1. Culture is a very broad and most humanized concept. Simply put, culture is the general name of human life elements in the region: clothing, crown, culture, things, food, housing and transportation. It is indeed very difficult to give an accurate or precise definition of culture. The interpretation of the concept of culture has always been controversial. However, there are similar explanations and understandings in dictionaries or encyclopedias in the East and the West: culture is the sum of material wealth and spiritual wealth created by human beings in the process of social and historical development.

2. Culture is the sum of all social phenomena and the inner spirit of the intelligent group.

3. It covers the history of intelligent groups from the past to the future, and is the content of all activities of groups based on nature. It is the whole of all material appearances and spiritual immanence of the group.

4. The specific content of human culture refers to history, geography, customs, traditional customs, tools, appendages, lifestyles, religious beliefs, literature and art, norms, laws, systems, ways of thinking, values, aesthetic tastes, spiritual totems and so on.

Although they have similarities in human culture, one essential difference is that the independent value and will of human beings are completely different from those of other intelligent groups.
