面 (miàn) means 'face' or 'surface', and 貌 (mào) means 'appearance' or 'looks'. Together, 面貌 literally means 'face appearance', but it extends metaphorically to refer to the overall outward appearance, visible condition, or general aspect of something — whether a person, place, organization, or even an abstract concept like a situation or era. It emphasizes what can be observed externally, often implying a change or contrast over time.

This word is commonly used in formal, descriptive, or evaluative contexts — for instance, when discussing social progress ('the面貌 of society has changed'), urban development ('the面貌 of the old district'), or health assessment ('his facial面貌 shows signs of fatigue'). Unlike simpler words like 外表 (wàibiǎo, 'outward appearance') or 样子 (yàngzi, 'look/appearance'), 面貌 carries a slightly more comprehensive, structural, or systemic connotation — suggesting a holistic impression shaped by multiple visible features.
