The Trademark Law has clearly stipulated that the post-registered name cannot conflict with the registered name. The Trademark Office wants to negotiate with you. Only if you agree to change your name or cancel it can the other party name. Letting you change your name should compensate you.

The trademark law is attached below for your reference:

Article 4 If a natural person, legal person or other organization needs to obtain the exclusive right to use a trademark for its goods or services in production and business activities, it shall apply to the Trademark Office for trademark registration. The provisions of this Law on commodity trademarks shall apply to service trademarks.

Article 13 Trademark holders who are well-known to the relevant public think that their rights have been infringed may request the protection of the well-known trademark in accordance with the provisions of this Law. A trademark applied for registration on the same or similar goods is a well-known trademark copied, imitated or translated by others, which is not registered in China. It is easy to cause confusion, so it is not registered and prohibited to be used. Where a trademark applied for registration on different or dissimilar goods is a well-known trademark registered by others in China, misleading the public and possibly harming the interests of the registrant of the well-known trademark, it shall not be registered and its use shall be prohibited.

Article 15 If an agent or representative registers the principal or the trademark of the principal in his own name without authorization, and the principal or the principal objects to it, it shall not be registered and the use thereof shall be prohibited. Where the trademark applied for registration on the same or similar goods is the same as or similar to the unregistered trademark previously used by others, and the applicant has a contract, business relationship or other relationship with others other than those specified in the preceding paragraph, knowing that the trademark of others exists, and others raise objections, registration shall not be granted.

Article 45 Where a registered trademark violates the provisions of Article 13, paragraphs 2 and 3, Article 15, Article 16, paragraph 1, Article 30, Article 31 and Article 32 of this Law, within five years from the date of trademark registration, the prior obligee or interested party may request the Trademark Review and Adjudication Board to declare the registered trademark invalid. For malicious registration, the owner of a well-known trademark is not limited by five years.
