SANGPO, CHINA - JULY 22: Hui Muslim girls leave a graduation for an Islamic studies course during the holy month of Ramadan at a mosque on July 22, 2014 in Sangpo, Henan Province, China. As part of a tradition dating back to the late 19th century and unique to China's 10 million Hui Muslims female congregations are led by female Imams in the women's only mosques of northwest China. Though able to teach and lead prayers for women, they are forbidden from overseeing funeral rituals or washing male corpses before burial. (Photo by Kevin Frayer/Getty Images)
