China occupies an important place in the Islamic world, but Islam in China is perhaps one of the most neglected and unexplored subjects in both sinological and Islamic studies. While there is abundant literature on Islam in the Near East, India, the East Indies, and Africa, we know few authorities on the subject of Islam in China, e.g., d'Ollone, Thierssant, Broomhall, Bonin, Hartmann, etc. Even in such comprehensive works as the Encyclopaedia of religion and ethics, the Encyclopaedia of the social sciences, the Encyclopaedia of Islam, and R. Levy's Sociology of Islam, we find merely fragmentary descriptions regarding the subject.
