Hui (回, húi) is a vague term, applied to followers of the Muslim faith all over China who have no other obvious affiliation bar Islamic dress and the absence of pork in their diets. Most Hui are descended from Middle Eastern traders who arrived in China over a thousand years ago; men can usually be distinguished by their skullcaps, women often wear headscarves or veils, while the sprouting of minarets is the most obvious sign that you’re in a Hui-populated area. While remaining Muslim, the Hui have otherwise long since integrated with Han culture; barring a few Persian or Islamic words, they speak Chinese as their mother tongue.
Ningxia is the officially designated homeland of the Hui, who today make up about 30 percent of the province’s tiny population of four million. However, most Hui do not live in Ningxia at all, but are scattered around neighbouring regions – particularly Gansu and Shaanxi – to the point where they often seem strangely absent within what is supposed to be “their” land. In Ningxia, as with all the autonomous regions of the Northwest, the central government has steadily encouraged Han immigration – or colonization – as a way of tying the area to the Chinese nation, but the situation of the Hui people is not comparable with that of the disaffected Uyghurs or Tibetans, since there is no talk whatsoever of secession.
The Hui population of Ningxia’s major cities is rather low, but to immerse yourself more fully in the culture take a trip to Guyuan, the Muslim districts in Xi’an, or the Lanzhou–Linxia route in Gansu province.
