Zheng-tong: Year 10, Month 7, Day 19
21 Aug 1445
The Commissioner-in-chief Mu Ang, regional commander of Yun-nan, memorialized: "Bu-la-lang Ma-ha Sheng-yi-su-la, the son of the Ava-Burma Pacification Superintendent, has written a wood-leaf letter (木葉文書) agreeing that in the 10th month (Nov 1445), they will finally send the bandit leader Si Ren-fa to the Gong-zhang region. They have handed over three inscriptions, one in gold, one in silver and one in iron, as indication of good faith. They require that they be given control of the Miao-sang region of Mu-bang. Now, we are sending the originally-sent chieftain Ha-da-su (Alt: Ha-da-la) to personally take the letter to the capital." The Emperor ordered the Ministry of War and the interpreters to conduct an investigation of Ha-da-su (Alt: As above). Subsequently, Imperial orders were sent to Ang and the others, requiring them to assess the situation and act appropriately. They were required to maintain military might, so that success could be achieved. Further Imperial orders were sent to Bu-la-lang Ma-ha Sheng-yi-su-la requiring him to swiftly send Si Ren-fa to the capital, upon which he would be promoted and rewarded. Ang and the others also memorialized: "The Long-chuan Pacification Commissioner Gong Xiang has said that Tao-meng Dao Pa-nang and Dao Mu-li, remnant followers of Si Ji-fa, stole his seal and his property. However, Dao Mu-li has claimed that Gong Xiang has lost the seal himself. We then sent people to seek them, but have not yet captured them." The Emperor said: "Gong Xiang has been newly appointed as an official. I am concerned that the yi's sentiments are not constant. Ang, you and the others are to spread Imperial grace and might in soothing and instructing the yi people. There must be peace."
