History

Jintan, known as Jinshan (金山) in ancient times, was a township of Yanling commandery since the reign of the Emperor Yuan of Jin. Then it was promoted by its inhabitants as Jinshan county to strengthen the local vigilance in the late Sui dynasty, without permission. As a densely populated area, the county was reestablished in about 688 under the Tang dynasty, but since there was a namesake in present-day Jinhua, Zhejiang, it was named after Jintan, a hill of Mao Mountain.[1][2]

  2. The name of Jintan supposedly derives from a huge altar inside a cave on Mao Mountain. According to one account, the altar was golden, thus it was designated "Golden Altar". In another account, the altar was named after a hill nearby, Jijin(積金山), and abbreviated to Jintan. See 茅山志 [Gazetteer of Mao Mountain]. 6.
