They are known as "living fossils" and "living steles" for studying ancient Chinese calligraphy art ", but many stone carvings are gradually disappearing

According to the experts of Wuyi Scenic Area Management Committee, Wuyi Mountain belongs to Danxia landform. The rock mass is composed of sandstone, and the cement is carbonate and clay, which is brittle and low hardness. In addition, Wuyi Mountain has a mid subtropical climate, which is warm, rainy and humid all the year round, providing an excellent environment for the growth and reproduction of vegetation, mantle vine, moss, etc., in addition to a wide range of uses.
