Phonology
In basic structure and vocabulary, the Dungan language is not very different from Mandarin Chinese, specifically a variety of Zhongyuan Mandarin (not Lan-Yin Mandarin) spoken in the southern part of the province of Gansu and the western part of the valley of Guanzhong in the province of Shaanxi. Like other Chinese languages, Dungan is tonal. There are two main dialects, one with 4 tones, and the other, considered standard, with 3 tones in the final position in phonetic words and 4 tones in the nonfinal position.
