A similar facility is known as dargah in a number of Islamic countries. Between 1958 and 1966, many Sufi tombs in Ningxia Hui Autonomous Region, and throughout northwestern China in general, were destroyed, viewed by the authorities as relics of the old "feudal" order and symbols of the criticized religion, as well as for practical reasons ("wasting valuable farmland"). Once the freedom of religion became recognized once again in the 1980s, and much of the land reverted to the control of individual farmers, destroyed gongbeis were often rebuilt once again.
