What is the first correct service that a lawyer hired by a family member should provide after a party is detained in criminal detention?

This has happened to my friend before. At that time, my family and I finally invited a lawyer Zhu after consulting a lawyer. He is a very professional lawyer, knowledgeable and experienced. After the entrustment procedure was completed, he did a lot of work, which moved even my friends. A friend said that lawyer Zhu went to the public security bureau and went to the detention center many times. In short, communication with family members is better and the case is handled smoothly. Later, other friends had something to do, and I also took them to see lawyer Zhu. He works at 908, the ninth floor of the Information Building, 200 meters west of the North Third Ring Road intersection of Huayuan Road. Whoever has an accident is in a hurry. If you can find a good lawyer to guide you, it will really save you a lot of trouble.
