Gǎn'ēn
Gǎn'ēn was a county on the western coast of Hainan, named for the river of the same name. Established under the Sui, it remained an administrative centre through many changes of dynasty. The early Ming placed it under Dānzhōu, then transferred it to Yázhōu in 1386. In 1501 the Li leader Fú Nánshé rose in rebellion in the western interior; his forces attacked several districts and captured Gǎn'ēn before imperial troops defeated the uprising.
