I am in a restaurant to help others, whether the restaurant is liable for compensation

Your request and ideas are not exaggerated at all, they are completely reasonable and legal and should be, let's not say whether you want your colleague to bear anything, since the place where you were injured was in a public place, and your actions were in the nature of righteousness and courage, and the reason for your injury was because some of the facilities in this place did not meet the safety regulations or posted obvious warning words in or near the place where the injury may be caused to remind everyone, so that the rescuer was also injured when the child was injured. And you also mentioned that you asked the store to shut down the equipment (power outage request) and the store didn't take this action, then obviously there is"Inaction"The existence of the facts is a serious negligent act. The two negligences of the store (the safety of the company and the gross negligence of omission) are fully responsible for the injuries you have suffered, and you should also pay compensation for the injured child (this compensation should be brought by the legal guardian of the deceased).

Judging from the several compensation claims you have made, they are all reasonable, and except for the moral damages you have raised, the amount of compensation can be determined by both parties through negotiation, and the other parts should be compensated in full. If you fail to reach a conclusion through negotiation, you can file a lawsuit with the court and resolve them through law.
