The phrase "另一方面" is formed through a vivid spatial and metaphorical construction. It conceptually begins with a single, acknowledged aspect or "face" (面) of a situation, visualized as one side of an object. The character "另" (meaning 'another' or 'separate') then explicitly directs attention away from that initial side. The inclusion of "一" (one) and "个" (a general measure word) completes the image, formally specifying "one other face" or "one other side", thereby constructing the idea of shifting to a distinct, alternative perspective or dimension of the same subject matter.
