The word 推销 is formed by combining two characters: 推 (tuī), which means "to push" or "to promote", and 销 (xiāo), which means "to sell" or "to market". Their union creates a vivid conceptual metaphor of actively "pushing sales forward", picturing the dynamic action of propelling a product or idea out into the marketplace to reach customers. It's less about a simple transaction and more about the energetic process of driving something into circulation and acceptance.
