This work from National Geographic China showcases white ducks (or geese) leisurely swimming on a tranquil water surface. The deep blue water, like a mirror, reflects the outlines of buildings or bridges, with ripples creating a dreamy blue tone. Three white waterfowl move gently in the upper left, adding vitality to the cool-toned scene. The overall atmosphere is serene and distant, capturing the harmonious blend of nature and man-made landscapes through realistic photography, conveying a rare sense of tranquility in the city. It is an entry in the 2010 National Geographic China Photography Contest, with photographer 「怡人山水」 (Yiren Shanshui) freezing this moment of tranquility with keen observation.
