Using unauthorized well-known brands for marketing is an infringement and illegal act, and there is no reasonable way to reduce the risk of legal sanctions. This behavior seriously damages the legitimate rights and interests of brand owners and will trigger a series of legal consequences, including but not limited to civil compensation, administrative penalties and even criminal penalties. Respecting intellectual property rights and abiding by laws and regulations are basic principles of business activities. Enterprises and individuals should conduct marketing in a legal and compliant manner, such as creating their own unique brands, establishing a good image through innovation and high-quality services, etc., in order to establish a sustainable business development model, rather than trying to take shortcuts through infringement. Any illegal and irregular behavior may ultimately lead to serious legal liability and reputation loss, which is not conducive to long-term development.
