Xuan-de: Year 5, Month 6, Day 13
3 Jul 1430
In Yun-nan, the Gan-yai Chief's Office, which was formerly under the Jin-chi Military and Civilian Command, was placed under the Yun-nan Regional Military Commission. At this time, the chief Dao Nong-meng had memorialized, requesting that, in accordance with the precedent provided by the Da-hou Chief's Office, Gan-yai also be raised to a subprefecture. He also memorialized that his territory was close to the Yun-nan Regional Military Commission, but that it had to pay its annual silver in lieu of labour to the Jin-chi Guard, which was far away. He thus requested that his office be placed under the Yun-nan Regional Military Commission as it would be more convenient to transport the silver to the provincial administration commission. The Emperor asked the Auxiliary Ministry of Personnel why Da-hou had been raised to a subprefecture. The reply was that it was raised because it provided a great amount of silver annually in lieu of labour. The Emperor said: "The offices established by my ancestors are fixed and cannot be changed. However, this office can, as a convenience, be transferred to the jurisdiction of the Yun-nan Regional Military Commission and instructed to pay its silver in lieu of labour to the provincial administration commission."
