The song "Một con vịt" (a duck) is a light-hearted, fun song describing the movements and sounds of a duck. It paints a cute picture of a duck flapping its wings, making noise, playing in water, and wagging its tail. It helps kids to learn about the sounds animals make and is also often used in activities to help kids develop coordination and language skills.

It is a classic Vietnamese children's song. Parents sing it to their children, who in turn pass it on. The song is catchy, playful, easy to sing, and widely taught to young children in kindergartens and elementary schools in Vietnam. For many Vietnamese, the song brings back childhood memories. It is one of the "first songs" many kids learn.
