Police officers and firefighters are the frontline heroes in public safety. Always ready for action, they have the dedication and diligence that brings a great sense of security to the community. In this installation, a body silhouette of an on-duty policeman stands at the street comer, showing great loyalty and commitment, which is embodied in the pair of swift upsoaring wings above. The silhouette is xtended to the ground and overlaps with another standing shilhouette, which represents a caring citizen. Let us follow him and raise our arms to salute our police and fire departments for their excellent services to the society.
