Brand: it is people's evaluation and cognition of an enterprise and its products, after-sales service and cultural value, and it is a kind of trust. Brand is the embodiment and representative of the comprehensive quality of a commodity. When people think of a brand, it is always associated with fashion, culture and value. When the brand culture is recognized and accepted by the market, the brand will produce its market value. A brand is a symbol added to a commodity by a manufacturer or distributor. It consists of names, nouns, symbols, signs, designs or their combinations. Trademark: refers to a brand or part of a brand that has applied to the trademark registration agency according to legal procedures and has been granted the exclusive right to use a trademark after examination and approval. Trademarks are protected by law, and no one may copy or use them without the permission of the trademark registrant. It can be seen that the brand has a wider connotation. Therefore, a trademark is a brand registered to obtain the exclusive right to use a trademark and thus protected by law. Brands and trademarks are enterprise names and their symbols, which are used to identify different kinds and different quality products of different producers and operators. A trademark is not only a symbol or symbol, but also a part of a name or appellation.
