1. If a fight between two sides causes injuries to both sides, but the injuries are not very serious, the public security organs will generally issue letters of introduction to both sides for injury identification, and both sides will do the injury identification themselves to confirm the injury level. Only minor injuries and above will be handled by the public security organs. If they are minor injuries, they will not be handled.
2. If it is a minor injury, you can file a criminal private prosecution, civil compensation, or criminal incidental civil action. If the other party does not go to the police station and the police station finally closes the case, then if he carries out the above lawsuit, it can be based on surveillance video.
3. If it does not constitute a criminal offence, it can be settled, but it only involves the issue of compensation. If you feel trouble, negotiate compensation with the other party. If you don't want to negotiate, you can let the other party sue. Since you have also been hurt by the other party, you can also sue the other party for compensation.
