What can a lawyer do during detention?

Legal subjectivity:

When a party is in criminal detention, a lawyer can visit him if his application for meeting is passed. According to the relevant provisions of China's Criminal Procedure Law, a criminal suspect has the right to entrust a defender from the day when he is interrogated for the first time by the investigation organ or takes compulsory measures. During the investigation, only lawyers can be entrusted as defenders. The defendant has the right to entrust a defender at any time.
