How to add a category to an already used trademark

Our company’s trademark is registered for a private club, but now if we want to make food, we can add it directly with the private club trademark we are using. Category? How to do it? How long does it take for a trademark application to be completed and put into use?

Trademark categories cannot be added directly to the original registered trademark. In this case, you can file a new trademark registration application. For details, please see China Trademark Network - Trademark Application - Application Guide - How to apply for registration of a commodity trademark or service mark. The time required for trademark registration is approximately 1 to 1 and a half years.
