The Changbai Grand Waterfall is located in the Heavenly Lake on the border between China and the DPRK.    

There are 16 mountain peaks surrounding the Heavenly Lake. A small stream flows down the gap between the northern Tianwen Peak and Longmen Peak and speeds up on crashed pebbles, forming the Chengcuo River. After flowing 1,250 meters, the stream gushes out from the mountaintop and forms a waterfall of 68 meters high. With a rip current, the waterfall seethes and roars all year round. A huge stone named Niu Lang Du (a place where the legendary cowherd crosses the river) situated on the mouth of the waterfall, cutting it into two steams. These two streams of water column, like two jade dragons, jump on the stones sticking out of the water and rushes into the deep valley, splashing up great waves of several meters high. White water smoke surrounds the waterfall, and its roar can be heard far away. It's really a great spectacle. In the sunlight, the refraction of the dense mist becomes rainbows, adding some mysterious and hazy color to the waterfall.     

The Grand Waterfall falls into the deep valley, forming rolling rip currents, and becomes the source of the Songhua River.
