Log on to China Trademark Network to make an inquiry (note: it is official website, not an advertising information website), click on the comprehensive inquiry of trademarks, and enter the Chinese or English you want to inquire (note: there are pre-inclusion, fine inclusion and inclusion options, and generally choose inclusion). After clicking Query, the query result page will pop up, and you can search related categories in related directories. In this way, you can basically register after the query (note: yes, not 100%). Of course, it is more convenient to find a professional trademark registration company, but a trademark costs more than 1000 yuan. I hope you can sign up successfully! I hope to achieve something because of this trademark. If you have any questions, please feel free to ask them.
