Yangzhou is a prefecture-level city in central Jiangsu province, People''s Republic of China. Sitting on the northern bank of the Yangtze River, it borders the provincial capital of Nanjing to the southwest, Huai''an to the north, Yancheng to the northeast, Taizhou to the east, and Zhenjiang across the river to the south. The first settlement in the Yangzhou area, called Guangling was founded in the Spring and Autumn Period. After the defeat of Yue by King Fuchai of Wu a garrison city was built 12 m above water level on the northern bank of the Yangtze River c 485 BCE. This city in the shape of a 3×3 li square was called Hancheng. The newly created Han canal formed a moat around the south and east sides of the city. The purpose of Hancheng was to protect Suzhou from naval invasion from the Qi. In 590 AD, the city began to be called Yangzhou, which was the traditional name of what was then the entire southeastern part of China.
