Located on the Taipei side of the Taibai Mountain Peak, the Grandpa Sea is 3,590 meters above sea level. It is a typical ice bucket lake with complete preservation in Taibai Mountain, forming in the ancient Quaternary glacier. The most striking landscape of the main peak of Qinling Mountain Taibai Mountain is the "Grandpa Sea" known as "Xianhu", which is 3,590 meters above sea level and is the highest alpine lake in my country.
