The local fashion shops reflect the Muslim Hui people of Ningxia. Although the Hui have adopted many features of the mainstream Han Culture their adherence to Islam influences their lives on almost all levels. They have their own dress-code, ethics, and follow Islamic dietary laws and reject the consumption of pork, the most common meat consumed in Chinese culture. They have produced a variation of Chinese cuisine known as the Chinese Islamic cuisine. Their mode of dress differs in that adult males wear white or black caps and females wear head scarves or (occasionally) veils.
