The word 崩溃 is formed through the combination of two characters, each contributing a vivid image of structural failure that together create a powerful metaphor. 崩 (bēng) depicts the sudden, catastrophic collapse of something solid and towering, like a mountain or cliff crumbling. 溃 (kuì) conveys the image of a breach or dissolution, as when a dam bursts or an army disintegrates. Fused into one term, the progression is from the initial, dramatic fracture (崩) to the subsequent, complete and unstoppable breakdown (溃), ultimately representing the total collapse of any system, structure, or state of mind.
