Ganzhou, a thousand-year-old city stands in the arms of water, with Zhangjiang, Gongjiang and Ganjiang rivers interweaving to form the urban framework of "three rivers and six banks." The three rivers brought nourish source to the ancient city, while also caused it suffered from floods for centuries.

A drainage system with open ditches, culverts and ponds was built, utilizing the terrain of the city, which is high in the southwest and low in the northeast, during the Northern Song Dynasty (960-1127), and the underground drainage network was named Fushougou Ditch because the direction of the drainage ditch resembles the ancient seal script characters for "Fu" and "Shou."

The wisdom of Fushougou Ditch has been integrated into the development of modern Ganzhou. A plot located in the core area of the city has been transformed into the city's central park, becoming a huge "sponge" for regulating urban hydrology. (Xinhua/Wan Xiang)
