Why Anqing was the capital of Anhui in Qing Dynasty?

Before liberation, from a geographical point of view, Anhui was still dominated by the Yangtze River basin, and the main development object was agriculture. Anqing, as a pearl on the Yangtze River, is developed along the Yangtze River and stands shoulder to shoulder with Nanjing, Jiangsu Province. Agriculture in Anqing and Huizhou is the focus. Before or after the Qing Dynasty, Huizhou's commerce was still two brushes in the whole country. In addition, the Yangtze River is a bridge for Huizhou merchants, so Anhui used to develop by waterways and grain-producing areas. Another reason is Anqing's military position, surrounded by mountains on three sides and water on one side. Anqing is also the narrowest section of the Yangtze River. The status of military strategists is very important and has always been a battleground for military strategists.
