How does elevation change from eastern Guizhou to western Guizhou?

The elevation of Guizhou province follows a continuously ascending profile from east to west, forming part of the broader Yunnan-Guizhou Plateau.1

The terrain rises from an elevation of approximately 2,300 feet (700 meters) in the eastern regions to about 6,600 feet (2,000 meters) in the west. Because of this gradient, the province's overall topography slopes at a steep angle from the center toward the east, as well as toward the north and south.1
