Is it the poem "Nine on the Moon"?

Not poetry. Poetry refers to China's ancient traditional poetry, represented by classical poetry, modern poetry and metrical words.

Poetry should follow strict rhythm requirements, and express social life and human spiritual world with concise language, dense composition, rich emotions and rich images.

Above the sky, the moon is old; On the stone of marriage, there is no rhythm and format required by poetry, so it is not a poem, but a sentence.
