There is no criminal responsibility for minor injuries, only administrative responsibility (public security detention and fines) and civil liability for compensation. Public security punishment shall be handled by the local public security bureau.
For civil compensation, the victim can ask Hainan public security for mediation or bring a lawsuit to the court: the court can bring a lawsuit to the court where the defendant's household registration is located (the county court in Jilin Province where the other party's household registration is located) or to the court where the case occurred. If the defendant has been away from his hometown for more than one year, he can bring a lawsuit to the court of his permanent residence.
