If you would fain command a thousand miles in view,
To a higher storey you are expected to go.
Comment
This poem shows what the poet sees and feels about as he ascends the high Tower. In the first two lines, he turns his eyes from the setting sun beyond the high mountains in the distance to the Yellow River at his feet, which flows out of sight eastward into the sea. What a sublime, panoramic picture of the vast land! Then he comes up with the masterful line "If you would fain command a thousand miles in view, To a higher storey you are expected to go" ,so its allegorical meaning is blended by landscape, emotion and philosophical thinking .
