2. There are two versions of culture: broad sense and narrow sense. Culture is a kind of precipitation and the cornerstone of the mainstream. Creativity is something that can only be produced based on precipitation. It can lead the mainstream when it is done, but it is not mainstream in the early stage, and whether it can become mainstream in the later stage remains to be determined.

3. Culture is a combination of broad sense and narrow sense. Broadly speaking, natural culture is called culture. It embodies the characteristics of geography and has its regularity, practicality and research value. Culture in a narrow sense refers to some rules between people and things in different fields and regions, and these rules are also valuable for use and research.

4. The design culture of the kingdom of heaven-the earliest design culture of the kingdom of heaven is still the excellent aesthetics of the traditional kingdom of heaven. For example, the luxury of royal gardens, the epitome of folk customs (paper-cutting, window grilling, embroidery) and so on. At present, the design culture of heaven is in line with the world. However, since the reform in the kingdom of heaven, matter has run too fast and thoughts have run too slowly. So many designs are appearances, which have deviated from the important basic theory of design based on pragmatism.

Many design books and famous designers agree that design and creativity, especially creative design, must be based on practicality. Otherwise, it is meaningless.
