an awe-inspiring view from a high vantage point or the feeling of reaching a pinnacle where others seem small by comparison.

站在这座摩天大楼的顶层，真有一览众山小的感觉。

the final line of the poem 'Gazing at the Mountain' by Du Fu, describing the view from Mount Tai's summit where all other mountains appear small.

登上泰山之巅，方能体会到“会当凌绝顶，一览众山小”的意境。
