Not by blood. Can you help your friend find a lawyer?

No, Article 33 of the Criminal Procedure Law has strict restrictions on entrusting lawyers: if a criminal suspect or defendant is in custody, his guardian or close relatives may entrust a defender.

Only my close relatives and I can entrust, but friends can't.

According to Item (6) of Paragraph 1 of Article 106 of China's Criminal Procedure Law, close relatives in criminal proceedings include husbands, wives, fathers, mothers, sons, daughters, brothers and sisters.
