First of all, you have to prove that you have copyright on it. In China, once a work is created, the author obtains the copyright. But in the lawsuit, the plaintiff still has to prove the existence of his copyright. The existence of copyright, in addition to the objects and rights guaranteed by the above written laws, the plaintiff must also prove that (1) the work is original. The requirements for obtaining copyright are different from patent rights, and must be novel, creative and practical. As long as the copyright is original, that is, as long as it is created independently through personal efforts rather than plagiarizing or copying other people's works.
Secondly, you have to prove that the other party has infringed, that is, infringed on several special rights of the copyright owner protected by law. Copy, exhibition, performance, distribution, etc.
