Táoyuán
Táoyuán lay between Sùqiān and Qīnghé in the watery plain of northern Jiāngsū. The Yellow River passed close to the town, while another channel ran to its south. After the river took the Huái’s course, embankments had to protect both the settlement and the canal route on which grain was carried north. A dyke was built west of the town in 1659.
