Legal basis: Article 120 of the "Criminal Procedure Law of the People's Republic of China" should be checked by the criminal suspect and read to him if he is illiterate. If there are omissions or errors in the records, the criminal suspect can submit supplements or corrections. After the criminal suspect admits that the transcript is correct, he shall sign or seal it. The investigator should also sign the record. If a criminal suspect requests to write a confession, he shall be allowed to do so. When necessary, investigators may also require criminal suspects to write a confession in person.
