Zheng-tong: Year 10, Month 3, Day 15
21 Apr 1445
Imperial orders were sent to the Commissioner-in-chief of the Left Mu Ang, regional commander of Yun-nan, and the Military Consultant and Vice Minister of the Right Yang Ning. The orders read: "I have received the wood-leaf letter (木葉書) from Bu-la-lang of Ava-Burma, which you forwarded, agreeing that when you and Han Gai-fa of Mu-bang reached Gong-zhang he would hand over the bandit leader Si Ren-fa. However, Han Gai-fa has written stating that Bu-la-lang wants to demand territory. Who is sending the bandit leader? It is not clear. When these orders arrive, if reports from Ava-Burma and Mu-bang have been received, you are to examine the situation and assess what measures to take. You are not to deploy the troops and cavalry without authority, as it is possible that the actions will result in you falling into their evil traps. If reliable reports are received, you should send a letter praising and encouraging them, ordering them to send Si Ren-fa, and noting that they will be promoted and greatly rewarded. You are senior ministers of the state and you should maintain your vigilance. The bandits' sentiments are changeable and you certainly must not treat them lightly, as thereby you will bring harm to the state's authority and orders. You must think very carefully about your arrangements and ensure security. Thereby you will be according with the importance of the task I have assigned to you."
