Yong-le: Year 1, Month 10, Day 12
27 Oct 1403
Lang-xun-jian, who had been sent by his leader, the Ava-Burmese chieftain Na-luo-ta, offered tribute of local products. Formerly, the Xi-ping Marquis Mu Sheng had sent the judge Deng Bo-tong and others to go and instruct Na-luo-ta. At this time, Lang-xun-jian transmitted Na-luo-ta's words, saying:
"The people of Burma (緬人), although situated on a distant border, have heard that the Sage Emperor has ascended the throne and all wish to become his subjects. However, our road passes through Mu-bang and Meng-yang and there are many obstacles. It is requested that you issue orders conferring upon me the headwear, robes and seal of office, so that I can rely on Heaven's majesty and yearly can offer tribute. Thereby I will be able to avoid insults and oppression."
The Emperor approved his request. The Ministry of War established the Ava-Burma Pacification Superintendency with Na-luo-ta as the pacification superintendent. Headwear, robes and a seal were conferred upon him.
