The Dungan people of Kazakhstan and Kyrgyzstan (with smaller groups living in other post-Soviet states) are the descendants of several groups of the Hui people that migrated to the region in the 1870s and the 1880s after the defeat of the Dungan revolt in Northwestern China. The Hui of Northwestern China (often referred to as "Dungans" or "Tungani" by the 19th-century western writers as well as by members of Turkic nationalities in China and Central Asia) would normally speak the same Mandarin dialect as the Han people in the same area (or in the area from which the particular Hui community had been resettled). At the same time, due to their unique history, their speech would be rich in Islamic or Islam-influenced terminology, based on loanwords from Arabic, Persian and Turkic languages, as well as translations of them into Chinese. The Hui traders in the bazaars would be able to use Arabic or Persian numbers when talking between themselves, to keep their communications secret from Han bystanders. While not constituting a separate language, these words, phrases and turns of speech, known as "Huihui hua" (, "Hui speech"), served as markers of group identity. As early 20th century travellers in Northwestern China would note, "the Mohammedan Chinese have to some extent a vocabulary and always a style and manner of speech, all their own".
