The signature of the conversation feeling must be signed by the interviewee.

According to the rules of conversation, conversation record should have his signature. After the interviewee confirms the authenticity of conversation record's content, he should first show that conversation record's content is true and effective, and then sign it.

Heart-to-heart talk with conversation record is usually more formal and true, because heart-to-heart talk does not require the parties to sign after interrogation, so it should be written down.
