Jing-tai: Year 7, Month 5, Day 21
23 Jun 1456
Previously, the chief envoy Nai Ai, the deputy envoy and others from the country of Melaka were coming to Court to offer tribute. After they arrived in Xin-hui County in Guang-dong, Nai, because he had committed rape (犯姦), killed himself. The deputy envoy Wu-sha then completed the [tribute] duties and was returning when Ma Gui, an interpreter in the Court of State Ceremonial and others memorialized on the basis of claims by Ya-mo, a fan person, that Nai had brought pearls which shone at night and cat's-eye which had not been presented in tribute. The Court believed this and sent the Vice Director Qin Yong and, together with Gui, they took Ya-mo and the others to Guang-dong with them to investigate the matter with the local officials. At this time, the Guang-dong grand defender, the regional inspector, officials of the three offices and Yong jointly memorialized that they had carried out an item-by-item examination of the baggage of Nai's sons and daughters, but that none of the previously-stated precious goods had been found. It was ordered that Gui and so on be arrested and sent to the Judicial Office, and that they be punished in accordance with the law.
