Wangong Dike is close to the East Taihu Lake and echoes the Suzhou Bay Bridge. Looking down from the air, it presents a sharp contrast between modernity and history. Wangong Dike is named after Wan Qingxuan, a water conservancy expert in the Qing Dynasty, who built the road from Sanli Bridge to Dapu Bridge. Now this road has become a national cultural relic protection unit and one of the important heritage sites of the Grand Canal, the "Jiuli Stone Pond".
