Geological introduction: The Wuyi Mountains where the scenic spot is located mainly contains pre-Sinian and Sinian metamorphic rock systems, Mesozoic volcanic rocks, granite and clastic rocks. Strictly controlled by geological structures, deep fractured valleys and fault block ridges with steep rock walls that are dozens of kilometers long have developed in the west, resulting in winding and winding streams and Danxia landforms such as columns, cones, and cliffs, which are the first of their kind in my country. Among the landforms, it is a natural landscape area with the most beautiful mountains, the most types, the most concentrated landscapes, the best combination of mountains and rivers, the best sightlines and the highest accessibility. For this reason, it also enjoys a special status among China's famous mountains.
