The validity period should be marked next to the qualification.

A trademark is actually a brand, which is a sign that a commodity/service is different from other commodities or services. Simply put, a trademark is the name given to its own goods/services by the providers of goods/services, but not all marks are trademarks. Trademarks must be distinctive, conform to social public order and good customs, and be registered by the State Trademark Office. Only when it is recognized can it be called a trademark.
