If the injured person has no witness and the other party refuses to admit it, the party concerned should choose to call the police in time, because the police's police records and relevant investigation records can be used as evidence in this case. If the victim fails to call the police in time after being beaten, resulting in no direct evidence, the police can help find evidence by calling the police afterwards. The victim's statement can prove the other party's criminal behavior and can also be used as evidence.
