Wàn'ān

Wàn'ān was the seat of a county and military prefecture on eastern Hainan. Founded under the Tang, the county later served as the centre of Wàn'ān Military Prefecture, which also governed Língshuǐ to the south. In 1368 the Ming changed the prefecture into Wànzhōu under Qióngzhōu. The attached county was absorbed into the zhou in 1439, so that its households came directly under the regional administration. Wànzhōu remained an important centre on the island's eastern side under the Qing.
