In Chinese Buddhism, peasant families worked monastic-owned land in exchange for paying a portion of their yearly crop to the resident monks in the monastery, just as they would to a feudal landlord. In Sri Lanka and in Tibetan Buddhism, the ownership of a monastery often became vested in a single monk, who would often keep the property within the family by passing it on to a nephew ordained as a monk. In Japan, where civil authorities permitted Buddhist monks to marry, the position of head of a temple or monastery sometimes became hereditary, passed from father to son over many generations.
