Yílún

Yílún was the seat of Dānzhōu in northwestern Hainan, near the river from which the older name Yìlún was taken. Under the Song it also governed Chānghuà Military Prefecture. The Ming restored the name Dānzhōu, with Yílún as one of its counties, but abolished the county in 1440 and placed its households directly under the zhou. In the early fifteenth century the Li chief Wáng Xiányòu helped persuade other communities to submit to the Ming and was appointed deputy prefect of Dānzhōu.
