The Court Fangshi Who Was Sent to Find Immortality Itself

The historian Sima Qian's Records of the Grand Historian preserves one of the best known fangshi episodes: Qin Shi Huang, the first emperor of a unified China, obsessed with prolonging his own life, dispatched the fangshi Xu Fu around 219 BCE with a large expedition and instructions to find the mythical islands of the immortals and bring back their elixir, an expedition from which, according to the traditional account, Xu Fu never returned to report, later legend in China, Korea and Japan elaborating the story into claims that he settled and founded a lineage overseas, claims historians treat as folklore rather than established fact.

Fangshi of this kind operated as court advisors specifically because early Chinese emperors themselves funded and encouraged the search for immortality and occult knowledge, a royal patronage documented across several early dynasties that gave the fangshi both resources and influence considerably beyond what an isolated village diviner or healer could command, and it is this same court-level ambition, the systematic pursuit of longevity and transcendence rather than only everyday divination, that later organised Daoism inherited most directly from the fangshi tradition.
