‘汗珠’ literally combines ‘汗’ (hàn), meaning ‘sweat’, and ‘珠’ (zhū), meaning ‘pearl’ or ‘bead’. Together, it forms a vivid, poetic noun meaning ‘bead of sweat’ — referring to small, round droplets of sweat that form on the skin, often visible on the forehead, temples, or upper lip. The character ‘珠’ adds a visual and tactile quality, emphasizing the rounded shape and glistening appearance of sweat under light or heat.

This term is commonly used in descriptive writing, storytelling, and everyday speech to convey physical exertion, nervousness, fever, or intense emotion. It’s more evocative and slightly literary than plain ‘汗’, but remains fully natural and widely understood across age groups and registers. You’ll encounter it in novels, news reports about athletes or workers in hot conditions, and even casual remarks like ‘他额头上全是汗珠’ (His forehead was covered in beads of sweat).
