In 1667, Jiangsu was established because of the east-and-west separation of Jiangnan Administration Commission. The name of the province is the abbreviation of the “Provincial Administration Commission that administrates Jiangnan covering Jiangning, Huaian, Yangzhou, Xuzhou, Haizhou and Tongzhou” and the “Provincial Administration Commission that administrates Jiangnan covering Suzhou, Songjiang, Changshu, Zhenjiang and Taicang”.
