Yong-le: Year 1, Month 4, Day 15
5 May 1403
The Messenger Yang Bo and others were sent to carry Imperial orders and take them to instruct the attendant officials and elders of Annam. The orders read: "I have received Hu Di's memorial which says that the ruling Chen family line was broken and that Di, a son of a woman from the Chen family, had been pushed forward by the people to temporarily manage state affairs and preside over the sacrifices. He wishes to be enfeoffed with a title and to rule the region as king. As Annam is distant I am unable to immediately place trust in what has been said. I am especially sending a Court messenger to go and make enquiries of you as to whether there are any remaining members of the Chen family line who could inherit the throne and whether Hu Di's claim about being pushed forward to the throne is true or false. You are to present a factual memorial about all of this with no deceit and nothing hidden." Those people who had been sent by Di to offer tribute were rewarded and sent home.
