Sanzhi did not develop into a Han society until early 20th century. However, the local residents have performed well continuously and made it an admirable district, especially in culture and humanities.
In Shimen, there used to be a traditional Katagalan village with a long history, named "Alilo," meaning "The Land by the Sea." There were semi-pit stone houses of about only two meters in height.
Jinshan is the place on the northern coast with the earliest human developments. Jinbaoli, the earlier name of Jinshan and meaning "harvest," had been a well-developed tribal village of the Pingpu people by the 17th century. And in the 18th century, streets were formed in the place which is now the bustling area of Jinshan.
The Masu River in Wanli flows through an area over a fault. The left side, where there are platforms suitable for farming, is the area where most of the residents of the district live. And the right side is a place of sedimentary rock with many coal mines.
The delta formed at the estuary of Tamsui River on the Bali side provided a good place for Dapengkeng and Shisanhang cultures to develop. However, with limited hinterlands, this place developed into a transfer point between the sea and the Taipei Basin for the early settlers. Lingyun Temple is the religious center of this area.
