Burials of eminent Quanzhen masters, particularly in the form of extravagant assembly-funerals, served as the initial step in the development of a Quanzhen-style ancestor worship. This ancestor worship functioned as the bedrock of a thriving Quanzhen lineage-building movement in thirteenth-century north China. Quanzhen Daoists attributed great significance to the physical remains of a lineage's founding master and commonly conducted multiple burials of the master. Each instance of reburial presented an opportunity for specific lineage members to assert their lineage identity, as well as ownership over the founding master's spiritual and material legacy. Lineage members commonly materialized their ancestor worship through a series of memorial objects established within a hosting monastery, including tombs, statues, portraits, memorial shrines, and commemorative steles. These lineage-building efforts strengthened dynamic networks of people, monasteries, and material culture, shaping regional interactions and transformations in north China under Mongol rule.
