How to claim compensation for being hit in the head with bricks when fighting with others?

If you can ask for an injury appraisal, let the case-handling unit take you to the forensic expert appraisal. It seems that I have opened a letter of introduction, so I can go by myself. There is no point in suing. I suggest you go to the public security organ for mediation first, because you fought back because of this fight. If you want the public security organ to handle the case according to law, the other party will at least be detained in accordance with the law, then the person who made the move there will also be detained (the law is fair), and the public security organ will close the case after handling it according to law (public security detention). Regardless of the compensation, you have to file a civil lawsuit with the court yourself. According to national standards, the court will award you compensation. Therefore, it is not cost-effective for the public security organs to deal with such a thing as you. Mediation is the best policy, because mediation, the two sides negotiate on their own, as long as the other side is willing to pay to avoid trouble, they can overcharge medical expenses and other losses. Personally, it is reasonable to double the medical expenses and lost time. For example, 500 yuan for medical expenses and 500 yuan for lost time add up to 1000 yuan, and you can ask the other party to compensate you for 2000 yuan. But you can quote more at first, leaving room for bargaining. If you think the problem is not big, go to the hospital less, and let the hospital make money. No matter how much you pay for medical treatment, it is not good for you. In case the other person is too poor to pay your medical bills, it's your own bad luck. Not only will they be detained together in the end, but they will also bear the medical expenses themselves. Even if the other party loses, it is not too much medical expenses, and the amount of compensation from the other party must be too much. Mainly depends on each other's attitude and endurance.
