Xuan-de: Year 5, Month 6, Day 7
27 Jun 1430
In Yun-nan, the Meng-mian Chief's Office and five police offices at Dian-tan, Mu-fu, Lei-bang-ha, Qiu-long-mo and Meng-lun were established. At this time, Jing-dong Prefecture memorialized that Meng-mian and Meng-shu which were under its jurisdiction, were secluded far away and that they had been repeatedly attacked by foreign bandits. It requested that Meng-shu be merged with Meng-mian, that a chief's office be established, that the local commander Jiang Song be appointed as Chief, that the office be subordinate to Jing-dong and that it be required to provide a further 50 liang of silver in tribute annually. Also, the Cha-shan Chief's Office memorialized that the yi people under its jurisdiction all lived deep in the mountains, that Dian-tan was a strategic place between Lesser Cha-shan and Wa-gao and that, as bandits were often appearing, the people could not live in peace. It noted that the interpreter Duan Sheng was familiar with principles and capable of calming the people's hearts. It thus requested that Sheng be appointed as a police officer and that a police office be established in Dian-tan. Also, Nan Dian Subprefecture memorialized that previously, it had been attacked, that its land had been occupied by by the Lu-chuan Pacification Superintendency and that it had relied on the Court's might to recover the territory. It noted that if offices were not established to officially mark the border, it was afraid that it would not be possible to hold back further attacks. It requested that police offices be established at four places -- Mu-fu, Lei-bang-ha, Qiu-long-mo and Meng-lun -- to guard it. The Emperor ordered the Auxiliary Ministry of Personnel to appoint officials in accordance with the memorialized requests.
