With the seasonal rise in temperature at Changbai Mountain Nature Reserve in Yanbian county, Jilin province, frozen Tianchi Lake has begun to melt.

The lake usually freezes in December and the ice finally melts in late June.

In recent days, tourists got a chance to enjoy both summer and winter scenery. As flowers have been in full bloom at the foot of the mountain, about half of Tianchi Lake, located in the volcanic cone of the Changbai Mountain's main peak, remains covered with ice.
