Trademark registration in China is based on the principle of "first registration, first acquisition", and only when applying at the same time will it be based on the principle of "first use, first acquisition". So whoever applies for a trademark first can, of course, sue the trademark infringer and ask for a name change or compensation for economic losses, but only if the trademark you apply for is flawless. You must have the subject qualification, that is, you must have the qualification to apply, and then there is no problem with the trademark you apply for, such as the common name of the product, and the place name above the county level cannot be used as a trademark.
