Karst landform is distributed in places like Guangxi, Guizhou and Chongqing. Guangxi is the place with the most widely distributed karst topography. KARST, refers to the geological process that water acts on soluble rocks mainly with chemical dissolution, supplemented by mechanical actions such as water erosion, subsurface erosion and collapse. Guilin landscape is a typical manifestation of karst terrain. Geographical landscapes like karst caves and sinkholes are formed by erosion. Dashiwei sinkholes in Leye County are the largest sinkhole group in the world, which is acclaimed as the "World’s Sinkhole Museum". The Yunhaitianzhou project is designed to experience such large-scale geographical wonders. The typical cases of viewing the large-scale geographical landscape of the canyon are as follows: The viewing platform of the Grand Canyon in Colorado, Arizona, the United States, and the suspended doughnut shape combines the soaring feeling of buildings with the tourism dynamic lines. Also, the buildings of the Shanxi Hanging Temple are integrated with the cliff wall, which is the representation of the Chinese landscape painting. The link between the cliff wall of Dashiwei sinkholes and the top of the mountain is covered with plants. So, tourists have to approach or exceed the cliff wall to experience the soaring feeling of the sinkholes. If the doughnut shape is adopted, huge support is needed at the rear to balance the front weight.
