Yángzǐ

Yángzǐ lay near the junction of the Yangtze and the canal leading north through Yángzhōu. As sand accumulated in the river, the island of Guāzhōu joined the northern bank and obstructed the old ferry approach. In 737 the official Qí Hàn cut the Yīlóu Canal across the new land, giving boats a more direct passage between the river and the canal.
