They believe that the breakwater's unique design, improved through Chinese technology, provides an ideal surface for coral attachment. Its stepped structure creates varying water depths, allowing corals to thrive under suitable conditions of depth and light.

The flow of water can draw in nutrients and oxygen, preventing the long-term accumulation of pollutants at high concentrations.
