The Chinese word **氛围** (fēnwéi), meaning "atmosphere" or "ambience," is a compound formed by combining two semantic characters. The first character **氛** (fēn) historically refers to an ethereal or vaporous aura, often with an auspicious or meteorological connotation. The second character **围** (wéi) means "to encircle," "to surround," or "a perimeter." Together, they create a metaphorical concept where **氛** (the intangible quality or mood) is perceived as being enclosed or pervading within the **围** (the surrounding space or environment), thus perfectly encapsulating the idea of an all-encompassing ambient mood.
