What's the difference between civil litigation and criminal litigation? What kind of contradictions between neighbors belong to?

Conflicts between neighbors belong to civil cases.

Civil cases are mainly civil disputes, which are aimed at civil relations between equal civil subjects and disputes caused by property relations and personal relations. For civil cases, the court adheres to the principle of not suing and ignoring, and the state public power organs will not take the initiative to intervene, and only the parties will handle it.

A criminal case is a violation of criminal law, which has serious social harm and should be punished according to law. All cases handled, except those told, are prosecuted by public prosecution organs, that is, people's procuratorates. This reflects the public power of the country, punishes crimes regardless of the will of the parties, and maintains social order and the long-term stability of the country and the well-being of the people.
