Zhou Wenting travels this storied body of water and finds its most fascinating spots. Some lucky cities can boast a great body of water, like London with the river Thames and Paris with the river Seine. Shanghai is privileged enough to have two great bodies of water: Huangpu River and Suzhou Creek.Huangpu River became famous when colonists established clusters of grand buildings on its banks on what became known as the bund. Today, the bund overlooks the breathtaking skyline of Lujiazui financial district. Shanghai’s other body of water, however, Suzhou Creek, has been somewhat overshadowed. Suzhou Creek links the inland cities of Jiangsu province with Shanghai. When the British colonists, who arrived in the city after it was opened as a commercial port in 1843 found they could reach Suzhou, Jiangsu province, via the creek, they named it Suzhou Creek. Thanks to its location, a large amount of cargo and travelers were transported via the creek before rail links were established. But after a century of being utilized as a waterway to transport goo
