hot spring
♨️ 温 warm + 泉 spring (a water source) = a hot spring
温 is warm/hot; 泉 is a natural spring or fountain of water. Together they name the warm water that bubbles up from the ground — a thermal spring or bathing spa. The ♨️ glyph itself is the standard map symbol for these.
泉 — white 白 above water 水
泉 is a pictograph showing a spring: water (水) flowing out from an opening in a rock, with 白 on top representing the mouth of the spring. The original oracle bone form depicted water streaming from a hollow. Its core meaning, 'spring' or 'fountain,' has remained stable since ancient times.
