Located in the west of Lanyang Plain, Sanxing Township is the junction between the Lanyang Plain and the hills and the highest point of the plain. Since ancient times, Sanxing Township was the place where the aboriginals of the hills and the residents of the plain trade with each other and an important place of ethnic and cultural conflicts and exchange. Sanxing Township has been a place of conflicts of multiple ethnic groups, including the many people that came here to cultivate the land after World War II times and traces of cultural integration could be seen anywhere.

Geographically, Sanxing Township is located at the junction of the hills, plain and rivers of Yilan. With such natural topography and environment, Sanxing Township used to be flooded by the rivers in the early days, the whole region was covered by the Lanyang River that flows in every directions like a web, forming a large "river land", characterized by frequent flood hazards. People that came to Sanxing Township in the early days to cultivate the wasteland diverted water for irrigation and grew rice, peanuts and sugarcanes on the land from through accumulation of sand in the river channels that flow like a web. Due to its geographic conditions, Sanxing Township is unique in Yilan for such characteristics as multiple ethnic groups and frequent flood hazards.

In the Qhing Dynasty, the immigrants that came to Yilan to cultivate the native land referred to Sanxing as "Pa Li Sha Nan". Sanxing was one of the places in the Yilan Plain that was developed late. Due to late development, Sanxing was not included when Lu Zhi Heng, Deputy Governor of Kavalan divided the Yilan Plain into 7 Baos to facilitate the counting of households in 1823 and was part of the Xi Zhou Bao until the number of Baos was increased from 7 to 12 in l835. The lands of Sanxing are sand bars in the Lanyang River and this is the unique of Sanxing due to the geographic environment in the early days. During the several decades following World War II, many people left Sanxing, leaving mostly the elderly people and children in the villages because Sanxing Township is located in the west of the Yilan Plain and socio-economic development remains stagnant there although it is no longer frequently flooded and the Barbarian invasion has long disappeared. However, during the recent one to two decades, with the hard work and efforts of people with vision, the production of onion, garlic, silver willow in Sanxing, especially the watery and sweet "Shangjiang Pear" have made Sanxing well-known and increased the income of local people as well as helped improve the economy.
