To sum up, a lawyer visiting a prisoner in a detention center needs to provide a power of attorney, an official letter issued by a law firm, the client's identification materials, and a lawyer's qualification certificate. Visiting right is a kind of pure power, which has one-dimensional characteristics and is limited to some extent.
