We fought four years ago and both sides were slightly injured. Now the other party is suing the right to health dispute. How should we deal with it?

We fought four years ago and both sides were slightly injured. Now the other party is suing the right to health dispute. You have to respond to this: First, the statute of limitations is three years. If it exceeds three years, the limitation of action will be lost, and the other party will lose the right to win the case. Secondly, if the limitation of action has not expired, you should collect evidence of your own injury and treatment, file a counterclaim, and offset the other party's claim.
