Zheng-tong: Year 9, Month 6, Day 5
20 Jun 1444
The Jing-yuan Earl Wang Ji, Minister of War and supreme commander of Yun-nan military affairs, advised: "To the South-east Yun-nan adjoins Jiao-zhi, while to the South-west, it controls the various yi. Within it, there are many man tribes. Their nature and customs are diverse and their ways of rebellion and guile are numerous. During the recent Lu-chuan rebellion, many people took advantage of being close to the border and secretly took military equipment and various other goods and stole into Mu-bang, Ava-Burma, Che-li and Ba-bai. There they made contact with the local officials and people. They traded what they had for what they needed and even taught them how to use the weapons. They hankered after women and sometimes stayed in those places and did not return. They also leaked out secrets about our border regions. Nothing could be more serious. It is because of this that border troubles have continually occurred, leading to many years of constant conflict. The military and the people have suffered greatly. It is requested that a strict guard be mounted to prevent people entering and leaving the borders and that if there are further transgressions, that there be mandatory punishment of death, with their family members being sent to miasma-ridden areas as soldiers. Also, the provincial surveillance commission should appoint patrol officers to carry out regular surveillance and inspection. In this way, border defences will be tight and we will see not mishaps." This was approved.
