Hunan Province governs 13 provincial cities and 1 Autonomous Prefecture. Hunan Province is located in Central China and the middle reaches of the Yangtze River. It is named "Hunan" because most areas are south of Dongting Lake. It is referred to as "Xiang" because the largest river in the province, Xiangjiang River, flows through the whole territory. The provincial capital is located in Changsha.
Hunan borders Jiangxi in the East, Chongqing and Guizhou in the west, Guangdong and Guangxi in the South and Hubei in the north. The land area is 211800 square kilometers, accounting for 2.2% of China's land area, ranking 10th among all provinces and urban areas.
Hunan is located in the transition zone from Yunnan Guizhou Plateau to Jiangnan hills and Nanling Mountains to Jianghan Plain. The terrain is a horseshoe landform surrounded by mountains on three sides and opening to the north. It is composed of plains, basins, hills, mountains, rivers and lakes. It crosses the two major water systems of the Yangtze River and the Pearl River. It belongs to subtropical monsoon climate.
Since ancient times, Hunan has planted Hibiscus trees. In the Five Dynasties, there was the saying of "Hibiscus country with thousands of miles of autumn wind", so it is also known as "Hibiscus country". Tan Yongzhi of the Tang Dynasty chanted it in the poem "the autumn wind is thousands of miles away, and Mao Zedong praised Hunan with" the morning light in the lotus country ".
