What design creates is the second nature which is more perfect and harmonious than the real nature. It also represents the spiritual world of human beings. It is to describe a new nature subjectively and qualitatively with its own language, side, technique and form. In conclusion, design can be expressed in a flexible and arbitrary way. With the emerging of more and more new processes, new technologies and new media, design contains more and more extensive meanings. Design is not subject to media. On the contrary, it is used to explore the essence of media. In the industrial age or information age, designers' ideas should always stay ahead of social development with no loss of their national features. Designers need to address core issues so that they can build a more balanced relationship with society than ever before.
