Introduction to Dujuan Gorge: It was named because of the lush azaleas on both sides of the gorge. It was originally called Shixiahao. The mountains on both sides here shrink to this point, and the narrowest point is a stone gap that can only allow one person to pass. If one person is in charge, no one can open it. The majestic artificial waterfall landscape of Dujuan Lake Dam is built on this terrain.
