In criminal cases, the public security unit is the responsible party to provide evidence, so the collection and acceptance of evidence is decided by the public security itself, and the victim does not need to provide it voluntarily. However, if the public security does not act or does not file a case at all after filing a case, it can file a case supervision procedure with the procuratorate or directly apply to the court for criminal private prosecution. Once the court thinks that the case belongs to the criminal category, it will order the public security to file a case for investigation.
