The Road Marker Tower on the Wucheng Water Highway in Yongxiu County is located at the entrance to the Wucheng Water Highway on the shore of Poyang Lake. During the high-water season, the road surface is submerged, making it appear as if vehicles are traveling on water. The tower's unique lighting design at the top guides passersby to admire this romantic spectacle.

However, its body is etched with a terrifying story. A giant LED light strip indicates the water level of Poyang Lake, and the 22-meter water level line from 1998 is strikingly prominently displayed on the tower. Looking down at the surrounding area—swamps, farmland, villages, and dikes—evokes the terrifying image of a massive flood that could engulf everything.
