Abstract: There was a large and continuous influx of population flowing west into the Xinjiang from inland China after the area of the Tianshan Mountains was reunified in the mid-Qianlong period． A large and important part of this migration were Hui people who lived in the Shaanxi-Gansu area． These migrants made a significant impact on the later composition of the Xinjiang population composition and local society． However，the existence of these Hui migrants has been ignored in academic studies． This paper discusses the opportunities and trends of Hui migration to the west; how the Hui made a living in Xinjiang and built migrant communities; and further shows the patterns and characteristics of the inland Muslim migrant groups． This research is based on a large number of examples in the Manchu and Han archives housed in Beijing and Taipei.
