Wáng Yuánlù 王圓籙 (c. 1849–1931) was the Daoist caretaker of the Mògāo 莫高 caves at Dūnhuáng who in 1900 discovered the sealed Library Cave (cave 17) and its manuscript hoard. He sold portions of the corpus to Aurel Stein (1907) and Paul Pelliot (1908); the early-20th-century dispersal of the Dunhuang manuscripts to London, Paris, St Petersburg, and elsewhere proceeds from his agency. The pseudo-Dunhuang manuscript that became the basis for KR3eh001 Fǔxíng jué zàngfǔ yòngyào fǎyào is traditionally said to have been privately retained by him from a shipment otherwise destined for Pelliot.
