Zheng-tong: Year 5, Month 9, Day 3
28 Sep 1440
Imperial orders were sent to the Yun-nan Regional Commander and Vice Commissioner-in-Chief Mu Ang and so on. The orders read: "In the past, as Lu-chuan and Mu-bang were repeatedly feuding and killing each other's people, I ordered you to pacify and instruct them not to cause trouble. You did not respect my orders and instead repeatedly requested troops to proceed on expedition to punish them. Fang Zheng, rashly courageous, took the lead in the fighting. You did not provide any assistance, with the result that Zheng died at the hands of the bandits. You were cowardly and thoughtless in planning. You wasted troops and resources without achieving success. If the bandit does not send an envoy to admit guilt this winter, then in the coming year, troops will have to be despatched. You must make thorough plans in respect of in which month to advance the troops, how many routes they should advance by, how many government troops and how many native troops will be needed, which places the troops should be deployed in, which areas grain should be sent to and which people should be employed in leading the troops and in transporting grain. Detail these plans and advise."
