Islam in China
A unique feature of Islam in China is the presence of female-only mosques. Among the Hui people, but not other Muslim ethnic minorities such as the Uyghurs, Quranic schools for girls evolved into woman-only mosques and women acted as imams as early as 1820. These imams are known as "nü ahong" (女阿訇), i.e. "female "akhoond"", and they guide female Muslims in worship and prayer. "Ahong" Du Shuzhen of Kaifeng became the first woman in Henan to perform the Hajj in 1992.
