Why didn't the suspect even see his lawyer during his detention?

According to Article 96 of the Criminal Procedure Law, a criminal suspect may hire a lawyer to provide him with legal advice, subrogation appeal and accusation after being interrogated for the first time by the investigation organ or from the date when compulsory measures are taken. If the suspect is arrested, the lawyer hired can apply for bail pending trial. When a criminal suspect hires a lawyer, it shall be approved by the investigation organ. The so-called case involving state secrets means that the case and the nature of the case involve state secrets, and it cannot be identified as a case involving state secrets because the relevant materials and handling opinions of criminal cases need to be kept confidential in the investigation process. In this case, the public security organ, as an investigation organ, cannot refuse the criminal suspect to meet the lawyer unless the case itself involves state secrets. If you refuse, you can report the situation to its superior public security organ. If the superior does not agree, it may bring an administrative lawsuit against the superior public security organ.
