Xu Fu (Hsu Fu; Chinese: 徐福 or 徐巿[1]; pinyin: Xú Fú; Wade–Giles: Hsu2 Fu2; Japanese: 徐福 Jofuku or 徐巿 Jofutsu; Korean: 서복 Seo Bok or 서불 Seo Bul) was a Chinese alchemist and explorer. He was born in 255 BC in Qi, an ancient Chinese state, and disappeared at sea in 210 BC. He served as a court sorcerer in Qin dynasty China. Later, he was sent by Qin Shi Huang to the eastern seas twice to look for the elixir of life.[2] His two journeys occurred between 219 BC and 210 BC. It was believed that the fleet included 60 barques with soldiers, ship crewmen, and 3,000 boys and 3,000 girls,[2] and craftsmen of different fields. After he embarked on a second mission in 210 BC, he never returned.[3]
