 Investigators who investigate and collect computer data or audiovisual materials such as audio and video recordings shall require the respondent to provide the original carrier of the relevant materials. If it is really difficult to provide the original carrier, a copy can be provided. Where duplicates are provided, the investigators shall state their sources and production process in the investigation record.
 The following evidence shall not be taken as the basis for ascertaining the facts of the case alone:
 （1） Statement of the parties;
 （2） Testimony given by a person without or with limited capacity for civil conduct that is not commensurate with his age, intellectual status or mental health;
 （3） Testimony stated by witnesses who have an interest in one party or his agent;
 （4） Audiovisual materials and electronic data with doubts;
 （5） Duplicates and reproductions that cannot be checked with the original.

It was a conscious and free declaration of intention, a goodwill and necessary one, and was intended to protect the legitimate rights and interests of the parties and identify the true situation of the case.
 2. The recording evidence has good technical conditions, clear identity of the interviewee, clear content, objective truth and consistency, has not been cut or forged, and the content has not been changed. Undoubtedly, there is other evidence to support it.
