Cross the river on the stone steps and walk in the scenery like a canyon. From the Qingyin Pavilion to the first line, along the west side of the Heilongjiang River, the mountain trails twisted and twisted on both sides of the river. Along the Heilongjiang River, you can see the Baiyun Gorge in the deepest part of the Shan Heavy Water Reconsideration Road. The outer gorge is open and clear, and the gorge is dangerous and cool. Entering the canyon, looking up, the cliffs on both sides of the cliff, only revealing the blue sky. The narrowest part of the canyon is only 3 meters, and only two people can pass side by side. Here is the "first line of the sky."
