Danxia, Yardang and Karst landforms are the three most common terrains in China. They are the result of different types of erosion. Combined with geological structure and climate change, these landforms decorate the earth with unique landscapes. In this 7-part photo series, we will take a peek at places in China that are representative of the characteristics of the three landforms.

Karst landform is characterized by caves, sinkholes or forest of tall toothy rocks left by the water erosion. The Miao Chamber in southwest China's Guizhou Province shows one of the karst features as the second largest cave in the world. The mind-blowing cave was sculpted some 100 million years ago when water contentiously flowed through different layers of rocks.
