What landforms cover most of Guangdong province?

The surface configuration of Guangdong province is diverse, but it is primarily characterized by hilly terrain. Smooth, low hills cover approximately 70 percent of the province’s total area.1

These hills are typically rounded and are frequently cut by various streams and rivers. In addition to these hills, the landscape features scattered, ribbonlike alluvial valleys. While level land is relatively limited, it is primarily found in the alluvial deltas formed where the province's rivers empty into the South China Sea. The most notable of these is the Pearl River Delta, which is marked by hilly outliers and a complex network of channels.12
