Abstract: Special population’s most obvious symbol is their special social experience and living status. Some of them (such as the mental patients) lack competence, others have special social experience (such as a penalty). They have certain difficulties in adapting or returning to normal social life, and hence need special care and help from the society. This article focuses on the institutional obstacles, as well as their causes, for special population to return back to their normal social life, and put forwards suggestions about how to eliminate these obstacles and construct the management and service system of special population.
