Introduction to Yujiang Spring: Yujiang Spring is located on the west slope of Changbai Mountain beside Tianchi, east of Yuzhu Peak, about 350 meters away from Tianchi. The spring water gushes out from the cracks in the rocks, gurgling, and soon disappears into the cracks of the rocks, becoming a hidden spring. It emerges from the ground about 20 meters away from Tianchi, and gurglingly flows into Tianchi.
