3 March
Orders are issued for the sixth voyage and envoys from 16 countries including Hormuz are given gifts of paper and coin money, and ceremonial robes and linings[31]
Orders are issued to Zheng He to provide Hong Bao and envoys from 16 countries passage back to their countries; the treasure fleet takes its usual route to Ceylon where it splits up and heads for the Maldives, Hormuz, and the Arabian states of Djofar, Lasa, and Aden, and the two African states of Mogadishu and Barawa; Zheng He visits Ganbali[33]
Zheng He is sent on a diplomatic mission to Palembang to confer "a gauze cap, a ceremonial robe with floral gold woven into gold patterns in the silk, and a silver seal" on Shi Jinqing's son [35]
Documents of the treasure voyages are removed from the archives of the Ministry of War and destroyed by on the basis that they were "deceitful exaggerations of bizarre things far removed from the testimony of people's ears and eyes," and that "the expeditions of Sanbao to the Western Ocean wasted tens of myriads of money and grain, and moreover the people who met their deaths [on these expeditions] may be counted in the myriads. Although he returned with wonderful precious things, what benefit was it to the state? This was merely an action of bad government of which ministers should severely disapprove. Even if the old archives were still preserved they should be destroyed in order to suppress [a repetition of these things] at the root."[56]
