Which criminal law firm in Dalian is better?

Lawyer Chen Sheng, a criminal lawyer in Dalian, is very good. He is a lawyer in Beijing and has an office in Dalian. He is in charge of cases in Beijing and Dalian, and has undertaken many major and difficult cases. Lawyer Bobby Chen is an authoritative lawyer. He was the one who handled my friend's previous case, and soon he was released on bail pending trial. But their lawyer's fees are more expensive, but they are worth it.
