Through rearranging layouts of existing public spaces such as the squares, piers and riverside promenades, as well as implementing light renovations and other projects for relevant riverfront buildings, landscape trails, streets and stores, the district has successfully conducted several flagship night economy projects, such as a 1,640-meter-long riverside walk and the Sanjiang piers used for night tours, to form the distinctive landmark features of the so-called Old Bund area.
