The last three words of the poem are show, cloud and pine.

Where is such a poem? If the last words of each poem are Xiu, Yun, and Song respectively, they won’t rhyme at all. If the last words must be these three words, it is not a poem, but three sentences. For example:

The scenic beauty of West Lake

The lake reflects the clouds in the sky

The dragon's claw pine on the bank of the embankment

There is always spring in all seasons

Only adding the fourth sentence is a five-character poem.
