Yancheng is surrounded by water dikes, and many water dikes have been built along the river around Yancheng. These dikes are centered on the east bank of Xijiang River and surround Yancheng. Cross-dike residence means that residents use the space of water dike to build houses on it, thus forming a long dike. Yancheng is surrounded by dikes and lives on the west side of the river across the dikes. This distinctive lifestyle originated from the ancient fishermen in China, and first appeared in Yancheng two thousand years ago, which is a symbol of local history and culture. It fully embodies the ingenious arrangement of ancient fishermen using dikes to use houses, which not only protects water resources, but also reflects the local ecological culture.
