There were rumours that the Jianwen Emperor managed to escape from Nanjing by disguising as a Buddhist monk. Some records reported that one year after he became emperor, the Yongle Emperor sent Zheng He and Hu Ying () to search for the Jianwen Emperor. In 1423, Hu returned and reported to the Yongle Emperor about his findings in a private conversation. The Yongle Emperor subsequently promoted Hu.
