Sanxing Township, formerly known as "Bali-Sa" (Kavalan language: Pressinowan, meaning "bamboo forest"), is located in the central part of Yilan County, Taiwan. It lies at the southwestern edge of the Lanyang Plain and connects to the Central Mountain Range. Geographically, it borders Yuanshan Township to the north, touches Wujie Township and Luodong Township to the east, neighbors Dongshan Township to the southeast, and shares its western and southwestern borders with Datong Township. With its flat terrain, fertile soil, and abundant water resources, Sanxing Township has become an important agricultural hub in Yilan County.
Sanxing is renowned for its agricultural specialties, the most iconic of which is the "Sanxing green onion"—famous throughout Taiwan for its high quality and sweet flavor. The township also produces silver willows and premium pears (commonly referred to as “Shangjiang pears”), and is known for its signature dish "burou" (deep-fried pork), which reflects the area’s integration of agriculture and culinary culture.
In addition to agriculture, Sanxing Township is also notable for its development of geothermal energy. In the 1970s, large geothermal resources were discovered in the Qingshui area, prompting the government to establish Taiwan’s first geothermal power plant—Qingshui Geothermal Power Plant—marking a significant milestone in the country’s green energy development.
Historically, the Sanxing area was once the borderland between the indigenous Kavalan and Atayal peoples. Settlements began to form in the 19th century following the stationing of Qing Dynasty troops. During Japan’s rule, the administrative reorganization of 1920 officially named the area "Sanxing" and incorporated it into Luodong District. It’s worth noting that Zhonghua Village, now part of Yuanshan Township, originally belonged to Sanxing but was reassigned in 1976 due to being geographically separated by the Lanyang River.
As for tourism, Sanxing Township offers a rich variety of natural and cultural attractions. The Annong River area serves as a major recreational space, featuring the Annong River Diversion Weir Scenic Area, river rafting, and riverside trails and bike paths—perfect for enjoying nature and outdoor activities. In the mountains, scenic spots like Longquan Hiking Trail, Quantoumu Trail, and the Naoliaokeng Ecological Education Park and Ancient Trail provide opportunities for hiking and environmental education.
In terms of lakeside scenery, Changpi Lake Scenic Area offers a tranquil lakeside environment with a surrounding walking path, making it an ideal place to relax and enjoy nature. In the cultural and religious sphere, traditional worship centers such as Caohu Yuzun Temple and Sanxing Ganquan Temple showcase the deep roots of local religious practices.
Moreover, the nostalgic Tiansongpi Railway Station, which retains architectural features from the Japanese colonial era, is a favorite photo spot for movie buffs and tourists. To promote local industry, the township also established the Sanxing Green Onion Culture Museum, which highlights the cultivation process and cultural value of green onions—serving both educational and tourism purposes.
Overall, Sanxing Township blends natural beauty, agricultural culture, historical depth, and tourist attractions, making it a dynamic and appealing area in central Yilan County. It not only reflects a strong local identity but also stands as an ideal destination for travelers seeking to explore Yilan.
