Located in Guixi City of Yingtan City, Zhang Tianshi, the founder of Taoist orthodox school, once practiced alchemy here. Legend has it that "Dancheng is a dragon and tiger, and the mountain is named after it" is a famous Taoist mountain with a long history. It is a beautiful mountain in the south of the Yangtze River. The peaks here stretch for tens of miles. Ninety-nine peaks have twenty-four rocks. They draw water as gently as possible. The streams around the peaks contain the masculinity of ninety-nine dragons, the green mountains and danshui, and full of spirituality. Longhu Mountain is a typical Danxia landform. The mountains are scattered and forest-like. This kind of geology is easy to weathering. Most of the mountains are smooth and have no edges and corners, so the mountains are neither high nor steep and ferocious. Elephant Trunk Hill, a famous scenic spot, seems to descend from the sky and plunge deeply into the earth. It is vivid and spiritual. It is called "the first God in the world". Half of the hillside is built with a flat trestle, which can be used to appreciate the outline of the mountain from different angles as you walk. Half way up the hill, I can see that Xianshan is green and dripping. Nature's ghosts and axes are supernatural, and the unexpected changes of the Danshi make people reverie infinitely. Here, on the blue waves of boat travel, people are in the middle of the painting, beautiful Danxia style and remote Taoist culture are intoxicating, lingering and forgetting to return. Most importantly, unlike the commercialization and bustling crowds of other scenic spots, there is still purity and tranquility that has not been fully developed.
