Project background: Duck River, also known as Minjiang River, Guanghan City, Sichuan Province. It is named because there are tens of thousands of migratory birds (commonly known as wild ducks) from the north each winter. Yahe River Wetland is one of the most important wintering places for various waterfowls in the Chengdu Plain. Its quantity and species are abundant, and it has a unique and irreplaceable role in the protection of biodiversity and the construction of landscapes.

The project uses about 12,000 sets of wall-washing lamps, about 8,600 sets of floodlights and about 6,000 sets of corrugated lamps.
