Xuan-de: Year 2, Month 11, Day 7
25 Nov 1427
A courier reported that the An-yuan Marquis Liu Sheng and others had been killed by bandits. The Emperor said: "As Sheng had previously been in Jiao-zhi and was knowledgeable of the land and people, I allowed him to again be employed there. However, I was worried that he might, through his bravery, become conceited, and thus strongly warned him to be controlled and careful. I also said that the bandits were unmatched in their skills and that they set ambushes and used false surrenders to entice their opponents. Sheng must not have heeded my words and it has resulted in this loss. Sheng failed me in this." The Emperor sighed and greived long about this.
