As far as China's enormous success in her economic reforms and development is concerned, Chinese rural migrant workers indeed have had their biggest share of contributions. Yet ironically in return, they have only received a disproportionate meager share of benefit rewards. These people represent a huge economically deprived group at the bottom of the social totem pole in China's metropolises. On the whole as a social group, their educational attainment is relatively low as compared to their average urban coworkers. As such being the case, their rights to access some of the cost-free cultural and educational enrichment programs in the society are limited and not always assured. Nevertheless and in general speaking, they manifest a strong and consistent desire to acquire all sorts of new and practical knowledge by means of accessing the resources and facilities of their local public libraries. It is suggested in this paper that public libraries are in a good position to give strong support to the central government's strategic planning for the development of a public culture service systema). In implementing such a government initiative with an unswerving purpose of advancing social justice and equality, public libraries should strife to provide as many as possible their library services at no cost to the public, especially to those socially deprived rural migrant workers.
