Are the trademark categories of the two enterprises the same? Because the other party is already a well-known trademark, legally speaking, they have been protected by all kinds. It will be more difficult for you to reapply for a well-known trademark, but it doesn't mean you can't get off. In addition, it depends on whether your trademark is registered before its trademark or before its well-known trademark application. If not, it will be in trouble. If your trademark is an old Chinese brand, it will be more beneficial for you to apply for fame, but I suggest you consult the local industrial and commercial department and try to solve it through negotiation!
