Abstract: Localization is an important proposition of professional social work practice and development.Although professional social work has entered the Chinese mainland for twenty years, yet it is not fully launched.Most Scholars' opinion focused on the integration of social work's "helping people to help themselves" philosophy with Chinese traditional culture.In fact, the difference of social structure is the greatest difficulty on professional social work's localization, especially the "family culture" feelings.To realize the localization of social work, it must improve the integration of western social work concept and "family culture" feelings, and build the substantive relevance of cultural identity to professional social work.
