Jīntán

Jintan was a county of the Zhenjiang region whose administrative identity reached back to 688. In 1356 it came under Zhu Yuanzhang's forces during the collapse of Yuan power, and it remained subordinate to Zhenjiang prefecture under the Ming and Qing. Its county seat was rebuilt during the Zhengde reign of the early sixteenth century, continuing a much older history of walls and local administration.

The county also belonged to the scholarly networks of Jiangnan. Duan Yucai, born outside Jintan's western gate in 1735, passed the provincial examination in 1759 and studied with Dai Zhen. Service as a magistrate took him to Guizhou and Sichuan, but scholarship continued alongside official work. After retiring he eventually lived in Suzhou, where he completed his influential commentary on the Shuowen dictionary, printed in 1815. His career connected a Jintan family and local education with the examination system, provincial office and the wider Qing study of ancient language and texts.
