1. Article 33 of the "Criminal Procedure Law" stipulates that while a criminal suspect or defendant is in custody, his or her guardian or close relative may also appoint a defender on his or her behalf. In other words, only close relatives or guardians of criminal suspects can retain lawyers.
2. To entrust a lawyer, you need: ID card, proof of relationship with the criminal suspect (police station certificate or household registration book can prove that you are a close relative), and a power of attorney issued to the lawyer.
Hope this helps
