Sun Moon Lake is Taiwan’s freshwater lake.  In ancient times, the area surrounding Sun Moon Lake was known as “Shuishalian”, translated meaning “where water and sand meet”.

Its area covered nearly half of Nantou County, including the township of Zhushan, Lugu, Mingjian, Shuili, Jiji, Puli, Yuchih, Renai and Guoxing. Under the district of the township of Yuchih, located at the foot of Taiwan's Central Mountain Range, Sun Moon Lake is situated between the island's overlapping high mountains to the East and its plains to the West. Sun Moon Lake, Toushe, Yuchih and Puli are all basin terrain.
