Shān quán (mountain spring) is a compound noun formed by combining 山 (shān), meaning 'mountain', and 泉 (quán), meaning 'spring' or 'natural fountain'. Literally, it refers to water that emerges naturally from the ground in mountainous areas—often clear, cold, and unpolluted. These springs are culturally valued in China for their purity and are frequently associated with tranquility, natural beauty, and traditional poetry or landscape painting.

In everyday usage, 山泉 appears in descriptions of scenery, travel writing, environmental discussions, and product branding—especially bottled water marketed as 'natural mountain spring water'. It carries positive connotations of freshness and authenticity. While not a technical hydrological term, it’s widely understood and evokes imagery of serene highland environments, often contrasted with urban or industrial settings.
