Yong-le: Year 4, Month 8, Day 26
7 Oct 1406
The eunuch Ma Bin and others were sent carrying orders with which to instruct Zhan-ba Di-lai, the king of the country of Champa. The orders read:
"Your grandson Bu Po-liang-wei-jiao-lan-de-sheng-na-mo and others whom you sent, have come to Court and offered tribute of local products. They have also said that the Li bandits of Annam have attacked and occupied your territory, driven off and seized people and livestock and been endlessly oppressive. Thus they submitted your request that troops be sent to punish Annam. The Li bandits have killed successive rulers of that country, usurped the throne, taken on a dynastic title and adopted a reign title, made things difficult for the people and produced indignation throughout the country. Chen Tian-ping, the grandson of a former king, was driven off by the Lis and placed his life in the hands of the Court. The Li bandits requested than Chen be returned to that country so that they could serve him as their lord. As I promote sincerity, I was not suspicious and I sent people to escort him back. However, en route, the bandits intercepted him and killed him. The Lis have opposed the orders of the Court and their crimes mount to Heaven. These crimes cannot be tolerated or excused. Thus, I have already sent the Cheng-guo Duke Zhu Neng, regional commander and "General for Subduing the Yi", and others to lead the Great Army in punishing their crimes. I have ordered that they mu st eliminate the Lis in order to bring peace to the people. You should strictly guard the borders and prevent the bandits' escape through strategic points. Those people from Annam who have previously gone to live in Champa will not be punished. However, no fugitives who arrive in future are to be concealed. If you apprehend the bandit Li and his son and their evil cohorts, bind them and send them to the capital. You will be amply rewarded for your efforts. You should exert yourself in this."
A silver seal plated in gold, silk gauze headwear, a gold belt, 100 liang of gold, 500 liang of silver, two sets of clothing made from patterned fine silks interwoven with gold thread as well as brocaded fine silks, silk gauzes and other goods were conferred upon him.
