The essence of brand is that the products, services or other advantages of brand owners over competitors can bring the same or higher value to the target audience. Values include functional interest and emotional interest.

In a broad sense, "brand" is an intangible asset with economic value, and its differences are expressed through abstract, unique and recognizable mental concepts, thus occupying a certain position in people's consciousness as a comprehensive reflection. Brand building is long-term.

In a narrow sense, "brand" is a kind of "standard" or "rule" with both internal and external characteristics. It is the general name of an identification system that makes it unique, valuable, long-term and cognitive by standardizing the concept, behavior, vision and hearing. This system is also called CIS (Enterprise Identification System) system.
