As a public welfare project, the biggest challenge is low budget. The bridge is like a leaf floating on the river, as the romantic poem saying Tiny boat is full of dreams and stars. The design uses soft curves to control, the middle is high and wide, and the ends are low and narrow. It outlines a slender and tensile volume, like the wings of a water bird when it takes off, full of instantaneous beauty. The downward and inward contraction of the bottom also greatly weakens the sense of heaviness caused by the wrapped water pipe, making the bridge body full of changes in every perspective.
