what is a trademark?

a trademark is a mark used to distinguish one operator's brand or service from other operators' goods or services. China's trademark law stipulates that trademarks approved and registered by the Trademark Office, including commodity trademarks, service trademarks, collective trademarks and certification trademarks, enjoy the exclusive right to use trademarks and are protected by law. If they are well-known trademarks, they will be protected by cross-category laws.

to sum up, it can be considered as trademark infringement by judging that the actor subjectively intentionally infringes the rights related to a registered trademark, objectively uses or sells it without authorization, or provides assistance and convenience for the infringement, resulting in damage results, and the damage results are causal with the above-mentioned behaviors.
