What is the topography of Guangxi?

Guangxi is generally a hilly basin landform, which is divided into six categories: mountains, hills, terraces, plains, rocky mountains and water surfaces. The mountainous area is mainly Zhongshan, which is more than 800 meters above sea level, followed by low mountains, accounting for about 39.7% of the total land area of Guangxi. Hills with an altitude of 200 ~ 400 meters account for10.3%; The landforms below 200 meters above sea level include valleys, valley plains, piedmont plains, deltas and low plateaus, accounting for 26.9%; The water surface only accounts for 3.4%.

Guangxi is located in the southeast edge of Yunnan-Guizhou Plateau, the second step of China's topography, and the western part of Guangdong and Guangxi hills, with high terrain in the northwest and low terrain in the southeast, showing a slope from northwest to southeast. Guangxi has a subtropical monsoon climate, spanning the four major water systems of Pearl River, Yangtze River, Red River and Binhai.
