How to complain about broken glass in Guangzhou hotel?

I suggest that you can complain to the industrial and commercial office, market supervision bureau and consumer association department where the merchant is located first. If it can't be solved, it can be solved through litigation.

The principle of presumption of fault is applicable to the personal injury liability of some special torts. The principle of presumption of fault refers to the principle of imputation that the actor is at fault from the fact of damage itself and determines the responsibility of the actor for causing damage to others. The so-called presumption refers to the result that the law or the judge infers the unknown facts according to the known facts. In fact, it is to infer and identify unknown facts based on known facts. Presumption of fault, also known as presumption of fault, refers to that in tort law, if the victim can prove the three elements of damage fact, illegal act and causality in litigation, and if the injurer cannot prove that he is not at fault for the occurrence of damage, then the defendant is presumed to be at fault in the act that caused the damage from the damage fact itself, and shall be liable for compensation.

It depends on the specific situation.
