In this article we explore the practical conditions of ritual practices of Hui and Uyghur Muslims in China. Ceaseless conflicts among different religious ideas and elements exist, but they are integrated into religious pluralism, which meets the needs of Muslims' daily practices. Furthermore, we probe the reasons for the resulting religious harmony through investigating the historical process of the formation of religious pluralism, and showing present ritual performances in which there is a hierarchically built ritual structure functioning to make religious integration possible, though different opinions regarding diverse religious elements occur elsewhere among Hui and Uyghur Muslims. Finally, the discussion supports the related assertion that rituals can be reliable and effective ways of understanding the sociological and psychological functions of religions, or religious beliefs, and other related socio-cultural realities.
