On a map, the Gaoping River and its tributaries look like blue veins on a leaf.
From its source on Yushan, the Gaoping River crosses 23 townships before finally emptying into the Taiwan Strait. Together with its five main tributaries—the Laonong, Qishan, Zhuokou, Ailiao, and Meinong rivers—it is 171 kilometers long and its basin covers an area of 3,257 square kilometers, the largest in Taiwan.
