Generally speaking, in criminal cases, there is a link of submitting evidence and cross-examination, in which the cross-examination of the parties is the main means to influence the evidence. According to Article 52 of the Criminal Procedure Law, judges, prosecutors and investigators must collect all kinds of evidence that can prove the guilt or innocence of criminal suspects and defendants and the seriousness of crimes in accordance with legal procedures. Article 61 stipulates that the testimony of a witness must be cross-examined and verified by the public prosecutor, the victim, the defendant and the defender in court before it can be used as the basis for deciding a case. If the court finds that a witness intentionally perjures or conceals criminal evidence, it shall deal with it according to law.
