Puzhuang Castle 

Jincheng village and Longmen village are within the Puzhuang Castle of Pucheng community in Mazhan Town. Outside of the castle, the ancient road goes through Zhejiang and Fujian provinces and the sea road starts from the Xiguan port.

The villagers from these two villages are the descendants of the soldiers who fought against the enemies to protect this ancient castle in the Ming Dynasty(1368-1644). The Puzhuang Castle had been established for three years (1384-1387), for defence against the enemies. In 1996, Longmen and Jincheng villages were listed as the important cultural relics units under the state-level protection by the State Council.
