Knife wounding has been detained and the victim has not been examined. Can he settle in private? If a settlement can be reached, can the lawsuit be withdrawn and can it not be sentenced?

This kind of criminal case belongs to public prosecution, and the victim has no right to withdraw it. Whether to pursue criminal responsibility shall be decided by the judicial organs according to the case and legal provisions. If both parties reach a compensation agreement and the victim understands, they can be given a lighter punishment instead of no punishment, and there will be no result of withdrawing the lawsuit.
