Wang Yuan, the prefect of Chao-zhou Prefecture in Guang-dong memorialized: "The envoy Nai Ai-na-bei-la and others who had been sent by the country of Siam, sailed across the ocean to come to Court. Their interpreter Nai Ma-sha and others came on shore, but then their ship was driven off by the winds and waves and its present situation is unknown. Sun Yu, the commander of Chao-zhou Guard and Wei Gang, a company commander of the same guard, plotted and made off with Nai Ma-sha's gold, pearls, precious stones and other goods. It is requested that their crime be punished." The Emperor said: "The distant persons were in straitened circumstances and unable to return home. Sun Yu and so on did not look after them well and instead robbed them of their property. How are they any different from bandits!" The regional inspecting censor was ordered to arrest and punish them.
