History of Wenshan
In 1894, the local gentry changed the name from “Fist Mountain” (拳山) to the more elegant “Fort Wenshan” (文山堡, from 文山秀氣). The greater Wenshan area (大文山區) is roughly the area of Bunsan District (文山郡), Taihoku Prefecture from the Japanese era. It included modern Wenshan district as well as Xindian, Shenkeng, Shiding, Pinglin, and Wulai.
