Xu Fu
Xú Fú (Chinese: 徐福 or 徐巿 (not to be confused with the character 市), Korean:서복- Seo Bok); was born in 255 BC in Qi, and served as a court sorcerer in Qin Dynasty China. He was sent by Qin Shi Huang to the eastern seas twice to look for the elixir of life. His two journeys occurred between 219 BC and 210 BC. It was believed that the fleet included 60 barques and around 5,000 crew members, 3,000 boys and girls, and craftsmen of different fields. After he embarked on a second mission in 210 BC, he never returned. Various records suggest that he may have arrived and died in Japan.
