Legal analysis: Copyright cannot be used as a trademark. Copyright and trademark belong to copyright, but there are many differences, so they can't be replaced.

legal basis: article 9 of the trademark law of the people's Republic of China applies for registration of a trademark, which shall have distinctive features and be easy to identify, and shall not conflict with the legal rights previously obtained by others. Trademark registrants have the right to indicate "registered trademarks" or registration marks.
