Sectarian violence between the Jahriyya and Khufiyya broke out repeatedly until the major episode of violence in 1781. In 1781, the authorities, concerned with the spread of the "subversive" "New Teaching" among the Salars, whom they (perhaps unfairly) viewed as a fierce and troublesome lot, arrested Ma Mingxin and sent an expedition to the Salar community of Xunhua County to round up his supporters there. In the Jahriyya revolt sectarian violence between two suborders of the Naqshbandi Sufis, the Jahriyya Sufi Muslims and their rivals, the Khafiyya Sufi Muslims, led to a Jahriyya Sufi Muslim rebellion which the Qing dynasty in China crushed with the help of the Khafiyya Sufi Muslims.
