The lake of Puma Yumco, located in Lhoka, Xizang, is known as the "Tears of the Fairy" and the "Baikal Lake of China". Every winter, the lake freezes over, and the ice surface becomes transparent enough to reveal the "blue" lakebed under the sunlight.
Yomzhong, at the age of 26, runs his own homestay beside Tangra Yumco Lake.
