What trademarks did you have when you were a child?

Trademark is a sign 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 it is a well-known trademark, it will be protected by cross-category laws.
