Xuan-de: Year 7, Month 10, Day 26
18 Nov 1432
The persons sent by Dao Zhao-san, the native-official pacification superintendent of Ba-bai/Da-dian offered tribute of local products and memorialized: "Bo-le regularly employs the troops of the native chieftains and Tu-ya (Alt: native lords?) to come and attack, killing people and carrying off property. It is requested that troops be despatched to punish them." The Emperor spoke to the accompanying ministers, saying: "I have heard that it is more than 5,000 li from Ba-bai/Da-dian to Yun-nan. It is a distant border region. Neither the native chieftains of Bo-le nor Tu-ya have ever given their allegiance. How can I trouble the people of China to go and do military service for distant yi. Further, the yi are barbarous and ferocious. It is certain that both sides share the blame. How can the transgressions be entirely due to Bo-le! We should issue Imperial orders of soothing and instruction, requiring them to maintain good relations with their neighbours, protect their territory and keep the people in peace. If the attacks do not cease, they are to memorialize again."
