My friend happened to apply for one this year, and I asked the right person. You can only apply for a trademark through an agency. It would be too troublesome for you to go to the Trademark Office. General agencies can provide registration. You can search for "Bozheng Trademark Platform" on Baidu. This online query and online application submission speed is faster than that of an agency. Generally, the query results will be available in 10 minutes, and the acceptance number will be issued on the same day of submission... I hope it can help you
