I happened to have applied for it before. Let me tell you about the general situation. No one should go to the Trademark Office to register a trademark. The agency will help submit the application. The application process is very fast. If you submit it on the same day, The acceptance notice will be issued within one month. Regarding the registration process and prohibitive regulations, you can search for "Bozheng Trademark Platform" on Baidu. At present, this platform should provide the most detailed and complete information... You can make your own choice.
