One sixth of the area in Jiangsu is covered by water. As a province grows with and thrives on water, the system of river chiefs originated here from the treatment of Taihu Lake. At present, there are more than 57,000 river chiefs at province, city, county, township and village levels in Jiangsu, which has made a full coverage of the water body.
