Xuan-de: Year 5, Month 6, Day 28
18 Jul 1430
As Han Men-fa, the pacification superintendent of Mu-bang, Si Ren-fa, the pacification superintendent of Lu-chuan/Ping-mian and Mang De-la, the pacification superintendent of Ava-Burma had all sent tribute of elephants, horses and local products, the eunuch official Yun Xian and others were sent to take Imperial orders to them and to confer upon them headwear, belts and variegated silks. At this time, Si Ren-fa and Mang De-la had memorialized that Han Men-fa had invaded their land and carried off people and livestock. Imperial orders were also sent to the Qian-guo Duke and Regional Commander Mu Sheng and the three offices, saying: "Both Lu-chuan and Ava-Burma say that Mu-bang has invaded their land and carried off their people. You, Sheng, should send an official who, together with a senior official from each of the the three offices, shall proceed together with Yun Xian to issue the instructions. If what has been said is found to be true, order that everything be returned, and that all look to their own affairs, guard their own territories and not attack the others. If they do not heed the orders, memorialize so that arrangements can be made."
