Personal suggestions: First, sincerely apologize to the other party, and actively compensate for each other's understanding. It is best to let the other party issue a letter of understanding and give up the legal responsibility of your relatives. Second, if the case has not been transferred to the court, if you have completed the first step and kept the necessary contact with the public security organ or procuratorate, then it is very likely that the public security organ or procuratorate will not prosecute your relatives on the grounds that this case does not constitute a crime. Third, even if you bring a lawsuit to the court, because the other party is only slightly injured and the circumstances are relatively minor, if you can get the understanding of the other party, then your relatives are likely to be sentenced to probation.
