Xu Fu
The "Shiji" also records that the Qin emperor dispatched the "fangshi" Xu Fu to obtain the elixir of life from the "xian" Anqi Sheng, who lived on Mount Penglai in 219 BCE, and then sent Lu Sheng "Master Lu" in 215 BCE. The emperor subsequently dispatched three other "fangshi" expeditions to the spirit islands, but none returned to China.
