According to the provisions of the Trademark Law of People's Republic of China (PRC), a trademark is a distinctive sign used by producers and operators of goods on the goods they produce, manufacture, process, select and distribute or by service providers to distinguish the sources of goods or services, including words, graphics, letters, numbers, three-dimensional signs, color combinations, sounds and combinations of the above elements. "Living well" belongs to language and conforms to the provisions of trademark law, so trademarks belong to the distinctive features that distinguish the sources of goods or services.
