In real life, Zheng probably looked very different. My school textbook mentioned only that he was a Hui minority (Muslim Chinese). In fact, the admiral was a descendent of a powerful Persian family. Records discovered in 1913 trace his lineage to Sayyid Ajall, who was sent by Kublai Khan to conquer Yunnan and became its first governor. In 2014, Chinese scientists at Fudan University in Shanghai put the theory to test. They examined DNA samples collected from descendents of the admiral’s close kin and found they originated from Persia, modern-day Iran. In addition to Zheng He, most senior officers of the storied Ming armada were also Muslims.
