as to avoid high and unnecessary expenses on both sides. They further violated longstanding Confucian principles. They were only made possible by (and therefore continued to represent) a triumph of the Ming's eunuch faction over the administration's scholar-bureaucrats. Upon Zheng He's death and his faction's fall from power, his successors sought to minimize him in official accounts, along with continuing attempts to destroy all records related to the Jianwen Emperor or the manhunt to find him. Although unmentioned in the official dynastic histories, Zheng He probably died during the treasure fleet's last voyage. Although he has a tomb in China, it is empty since he was buried at sea. Zheng He led seven expeditions to the "Western" or Indian Ocean. Zheng He brought back to China many trophies and envoys from more than thirty kingdoms, including King Vira Alakeshwara of Ceylon, who came to China as a captive to apologize to the Emperor for offenses against his mission. Zheng He wrote of his travels: We have traversed more than 100,000 li of immense water spaces and have beheld in the ocean huge waves like mountains rising in the sky, and we have set eyes on barbarian regions far away hidden in a blue transparency of light vapors, while our sails, loftily unfurled like clouds day and night, continued their course [as rapidly] as a star, traversing those savage waves as if we were treading a public thoroughfare.... Sailing charts Zheng He's sailing charts, the Mao Kun map, were published in a book entitled the Wubei Zhi (A Treatise on Armament Technology) written in 1621 and published in 1628 but traced back to Zheng He's and earlier voyages. It was originally a strip map 20.5 cm by 560 cm that could be rolled up, but was divided into 40 pages which vary in scale from 7 miles/inch in the Nanjing area to 215 miles/inch in parts of the African coast. Investigation into folios 19V to 20R of the Mao Kun Map which covers the Indian Ocean including South India, Sri Lanka, the Maldives, and East Africa suggests that it is a composite of four maps, one for Sri Lanka, one for South India one for the Maldives and one for around 400 km of the East African coast, no further south than 6 degrees south of the Equator. Each of these maps is positioned at a different orientation to fit with
