Qīnghé
Qīnghé lies in the low country where the Huái River and the Grand Canal meet. In 1415 the Míng commander Chén Xuān cut a channel west of Huái’ān, leading water from Guǎnjiā Lake to the Huái. Called Qīngjiāngpǔ, the new waterway became part of the route used to carry grain northward, and a busy settlement grew along it.
