The Danxia land-form denotes to a variety of landscapes located in the southeast and southwest China that "consist of a red bed characterized by steep cliffs”. It is actually an awesome form of petrographic geomorphology located in China. Danxia land-form is formed from red-colored sandstones and conglomerates of largely Cretaceous age. The land-forms appear comparable to karst topography that forms in areas underlain by limestones, however since the rocks that form danxia are sandstones and conglomerates, they have been known as "pseudo-karst" landforms. Danxia land-forms cover several provinces in southeast China. Taining County, Fujian Province has good examples of "young" danxia land-forms in which deep, narrow valleys happen to be formed. As the land-form gets older, valleys expand then one becomes isolated towers as well as ridges. 

The Danxia land-form is termed after Mount Danxia, probably the most well-known examples of the danxia land-form. A very peculiar feature of danxia landscape is the development of numerous caves of a variety of sizes and shapes. The caves are usually shallow and isolated, in contrast to real cost terrain where caves tend to form deep, interconnecting networks.
