I just saw this question and I would like to give you my suggestions. The registration of trademarks is managed by the State Trademark Administration, and the authorized filing agency assists applicants. The platform for online trademark registration can be found on Baidu Look for "Bozheng Trademark Platform", which is an online service platform of the Intellectual Property Alliance, providing online instant search and online application services. At the same time, there is a lot of policy trademark law information that can be searched on it. I hope my answer is helpful. Help you
