You can check whether a trademark has been registered on the China Trademark Search Network.

To use the China Trademark Network query, you must first determine the elements contained in the trademark: text, graphics, or letters. Each element is queried separately. Once an element cannot be registered, the registration certificate will not be issued for the entire trademark. In addition to basic inquiries (for example, the national emblem cannot be registered), the element cannot be registered as a trademark (these situations are explained on the China Trademark Online) and whether it has been registered before. It has been registered by other companies, and similar elements are not acceptable.

If you find it troublesome, I suggest you go to an agency and ask them to check it for you. It can be done in a minute, and most importantly, it’s free. I haven’t given you the address after talking for a long time. Just search it on Baidu. "Zhiyi.com National Trademark Registration Center" allows you to see a professional trademark registration consultation website, where you can conduct trademark registration consultation and free trademark inquiries.
