Zhèn'ān

Zhèn'ān was a hereditary native prefecture in the mountainous country of western Guangxi. It was governed by a branch of the Cén family, whose related houses held several jurisdictions across the region. In the Yuan, Cén Ālàxīn received Zhèn'ān while his brothers held Tiánzhōu, Sìchéng and Sī'ēn. The prefecture survived under the Ming and early Qing. In 1663 the Qing appointed a regular official to the district, and in 1729 reorganised Zhèn'ān as a prefecture under direct administration.
