The whole town is located on the hillside, which forms a unique hillside and stepped architectural landscape. It was prosperous in the early days due to gold mines, but once the mines were exhausted, they declined. After the 1990s, the film "City of Sadness" was filmed here, and its unique old buildings, slopes and customs attracted attention at home and abroad through the film, and it also brought vitality to this area and became a tourist attraction.
