(two) to meet and communicate with the criminal suspect, and to understand the case from the criminal suspect;
(3) Providing legal aid and acting as an agent for complaints and accusations against criminal suspects;

Article 43 When interrogating a criminal suspect for the first time or taking compulsory measures against him, the public security organ shall inform the criminal suspect that he has the right to entrust a lawyer as a defender, and inform him that if he fails to entrust a defense lawyer due to financial difficulties or other reasons, he may apply for legal aid from a legal aid institution.
