Hsinyi Township, which covers a third of the surface area of Nantou County, is Taiwan's second biggest township and offers visitors a magnificent landscape of rolling green hills, meandering streams, the nearby Tungpu hot springs, which are famous for their therapeutic waters, and the Yushan peaks in the distance.
丘陵起伏、青山環繞、溪流蜿蜓，遠可眺望玉山群峰；近可觀賞彩虹垂瀑，景觀壯闊，又鄰近水質優良的東埔碳酸溫泉──如此秀麗的休閒度假勝地，是面積佔南投縣三分之一、全台第二大鄉鎮的信義鄉。
