Zheng-tong: Year 6, Month 12, Day 28
8 Feb 1442
Imperial orders were sent to the Vice Commissioner-in-Chief and Yun-nan Regional Commander Mu Ang, the three offices of Yun-nan and the regional inspecting censor. The orders read: "Recently, Nong Lang-ju, the native-official assistant prefect of Guang-nan Prefecture memorialized that Shen Zheng, who is waiting to inherit the post of native-official magistrate of Fu Subprefecture had, without authority, appointed people to official posts and had joined forces with the rebellious bandit Wei Lang-luo. He noted that Zheng is also secretly serving Jiao-zhi and intends to borrow troops to attack and occupy the region of Guang-nan. Previously Zheng had memorialized that Lang-ju had raised troops, was following the false new king, had obstructed the roads and wished to destroy Fu Subprefecture. I have already ordered you to pacify or capture him as the situation allows. Now Lang-ju has memorialized that Zheng is engaged in rebellion. It is not know who is lying and who is telling the truth. You should conduct an investigation to find out who is in the right and who is in the wrong. Discuss the matter with the Ding-xi Earl Jiang Gui and the Minister Wang Ji. Once you have discovered the truthful one, despatch troops to capture or eliminate the other. Do not allow border troubles to erupt! If there has been falseness and deceit, it must be handled properly. Memorialize the facts."
