Tian-shun: Year 8, Month 3, Day 7
13 Apr 1464
The envoys sent by Pan-luo Cha-quan, the king of the country of Champa, memorialized that the country of Annam had attacked their country and demanded white elephants and other goods. They requested that, as was done during the Yong-le reign (1403/24), an envoy be sent to pacify them and erect a border tablet (界牌) so as to prevent further encroachments and end the hostilities. The memorial was sent to the Ministry of War which proposed that the interpreters be instructed to instruct the envoys to return home and advise their king that he should diligently observe propriety and the law, and guard his territory, so as to defend against external annoyance and not bring disaster upon himself. This was approved.
