The appropriate offices were ordered to arrange funeral matters and to have his body escorted back to the capital. Neng (zi Shi-hong) had his origins in Huai-yuan County, Feng-yang....In the second year of the Yong-le reign (1404/05), he was promoted to concurrent Grand Mentor of the Heir Apparent.
