The word **巅峰** (diānfēng) is a compound noun formed by combining two characters with nearly identical meanings: **巅** refers specifically to the "summit" or "top of a mountain," and **峰** means "peak" or "mountain crest." Their combination creates a reinforced, vivid metaphor for the "absolute pinnacle" or "zenith," leveraging the imagery of the highest possible point of a mountain to symbolize the utmost height of achievement, power, or development in any abstract field.
