Legal analysis: Within three months from the date of announcement, if the prior obligee or interested party thinks that there is a violation of the relevant provisions of China's Trademark Law, they may raise an objection to the Trademark Office. There are also two ways for dissidents to apply for trademark opposition by themselves: 1. Go directly to the trademark registration hall of the Trademark Office; 2. Handling by mail.

Legal basis: Article 3 of the Trademark Law of the People's Republic of China

Where a trademark applied for registration does not conform to the relevant provisions of this Law or is the same as or similar to a trademark registered or preliminarily approved by others on the same or similar goods, the Trademark Office will reject the application and refuse to report it.

article 31 where two or more applicants for trademark registration apply for registration with the same or similar trademarks on the same commodity or similar commodities, the trademark that applied earlier shall be preliminarily examined and approved and announced; If the application is made on the same day, the earlier trademark shall be preliminarily examined and announced, and the application of others shall be rejected without announcement.

article 32 an application for trademark registration shall not damage the existing prior rights of others, nor shall it preempt the registration of a trademark that has been used by others and has certain influence by unfair means.
