Anhui and Jiangsu are "twin provinces" of China, which have deep historical origins. Anhui and Jiangsu were formerly jiangnan province in the Ming and Qing Dynasties. This province covered the vast fertile soil on the four banks of the Yangtze River and Huaihe River, and was one of the richest and most important provinces at that time. In the 6th year of Emperor Kangxi of Qing Dynasty (1667), jiangnan province was divided into Anhui Province and Jiangsu Province, and there are still many political, economic and cultural ties between the two modern provinces.
