In addition, he was banished to Lung-chʻang in modern Kuei-chou, which was then inhabited by the barbarian Miao tribes, to become an insignificant executive in a dispatch station, whose duty it was to provide horses for rapid transportation. He started the journey in the spring of 1507 and arrived a year later, stopping over on the way to visit his father. Liu's agents pursued him and he escaped assassination only by throwing his clothing away by the Chʻien-tʻang River near Hangchow, thus suggesting suicide. Some accounts, to make the event more dramatic, have him escape by sea from Hangchow to Fukien and thence to Kuei-chou. More reliable chronicles, however, have recorded his trip overland from Hangchow to Kuei-chou. In Kuei-chou he taught the Miao aboriginals to build houses and live in them.

The Chʻü-tʻang was a hazardous gorge along the Yangtze River near the remote city of Kuei-chou (Guizhou); the dangerous Yen-yü Rock lies in the midst of the river in the gorge.
