Firstly, two concepts are clarified: private prosecution: minor criminal cases are brought by the injured party to the court, which is applicable to minor injuries. Public prosecution: public prosecution, that is, criminal proceedings in which the police station takes evidence and the procuratorate is the plaintiff (prosecutor), is applicable to minor injuries and serious injuries.
1. First of all, you should have a forensic "injury identification" (divided into minor injuries, minor injuries and serious injuries, not counting "disability identification"). The injured party was slightly injured, with a sentence of less than 3 years and a serious injury of more than 3 years.
I suggest that whether you are slightly injured or seriously injured, you'd better write a "complaint" to the police station and take the road of public prosecution, so that you can rest assured, because you can't provide a lot of evidence personally. Civil compensation can only be filed according to the arrangement of the procuratorate.
2. The amount of compensation depends on your disability level. You can issue a power of attorney from the police station and law firm to the municipal disability appraisal committee for disability level appraisal (10). I estimate that you are around 7 or 8. If it's Grade 8, the spiritual consolation money 1.5 million, the disability compensation for 20 years × the per capita net income of your occupation (local province) in the previous year× 30% (Grade 7 disability and so on, 40%), the living expenses of the dependents (per capita consumption expenditure in the province where your occupation is located× the number of years of the dependents 18 years old, and the elderly are under 60%)
