Gāo'ān
Gāo'ān is a river town of northwestern Jiāngxī west of Nánchāng, on the Jǐn River. It grew from the Hàn county of Jiànchéng and became the seat of Ruìzhōu: the Yuán made it Ruìzhōu Route and in 1369 the Míng turned it into a prefecture covering Gāo'ān, Shànggāo and Yífēng. Its scholars did well in the examinations; Zhū Shì, born here in 1665, served the Kāngxī and Yōngzhèng emperors and rose to be a grand secretary.
