Guizhou has high terrain in the west and low terrain in the east. It slopes from the center to the north, east and south. Guizhou's landforms can be divided into four basic types: plateaus, mountains, hills and basins. The plateau is mostly mountainous. It is called "eight mountains, one water, one field", and it is the only province in the country that is not supported by a plain.
