Zheng He was a Chinese admiral and diplomat from the early Ming dynasty. His extensive explorations along the Indian Ocean led to a major increase in China's political and commercial influence. He was born into a Muslim family as Ma He and later adopted the surname Zheng conferred onto him by the Yongle Emperor. He is also widely known in Chinese culture by the alias San Bao (三宝/三保), also spelled Sam Po, which in names of Southeast Asian temples can refer either to him or to the Three Jewels of Buddhism. 1371 – 1435; died at about 64. Alive at the same time as Joan of Arc, Johannes Gutenberg, Geoffrey Chaucer, Jan Hus, and Jan van Eyck. Wiki link
