Yong-le: Year 9, Month 3, Day 13
5 Apr 1411
The chieftain Dao Pa-leng and others who had been sent by Nang Guang, the native-official magistrate of Zhen-kang Subprefecture, came to Court. Previously, the Eunuch Xu Liang and other had been sent as envoys to the yi in the South-west. Their route passed through Zhen-kang and there they were obstructed by Nang Guang, who seized the goods they were taking to confer on others. When the events were advised, an envoy was sent with Imperial orders of instruction and castigation. Nang Guang was frightened and thus he sent persons to the Court to request forgiveness for his crime. The Supervising Secretary Zhou Rang and the Messenger Fang Jun were sent to caution and instruct him.
