‘辣手’ (là shǒu) literally combines ‘辣’ (là), meaning ‘spicy’ or ‘sharp’, and ‘手’ (shǒu), meaning ‘hand’. Figuratively, it describes something difficult to handle, manage, or resolve—like a problem so intense or complex that it ‘burns the hands’. It emphasizes the challenge or discomfort involved in dealing with it, often implying urgency, sensitivity, or high stakes.

This term is commonly used in spoken and written Mandarin when discussing tricky interpersonal situations, complicated administrative tasks, or delicate professional matters. While not formal in tone, it’s widely understood across age groups and registers. It’s rarely used for physical objects alone; instead, it modifies abstract nouns like ‘问题’ (wèntí, ‘problem’), ‘局面’ (júmiàn, ‘situation’), or ‘事情’ (shìqing, ‘matter’). The expression carries a slight nuance of warning or caution—suggesting the matter requires careful, skillful handling.
