There is no doubt that my pie is the best in the world. Is this sentence a literary work or a non-literary work? Why?

There are only four short sentences and thirteen words in the whole poem, which describes the poet's coming to Tennessee alone, without friends, becoming his favorite hometown school, vividly constructing a very three-dimensional "environment", expressing a lonely taste of living in a foreign country, and smelling a strong and profound homesickness, which makes people feel sad for a long time after reading it. The title of this poem is "A Man Came to Tennessee", which is a very plain language, and the words in the poem are equally simple and natural. The first sentence at the beginning of the poem is "beyond doubt". The poet's calm and firm definition makes people undoubtedly believe that her sentence is the most true and the cry of the poet's inner world. The second sentence says "I made the pie" and emphasizes "I". The poet made the pie himself (in his hometown), not bought it on the beach by the roadside. You can imagine the poet living in a foreign land and recalling the past in his hometown. The pie here already contains the whole hometown complex. The last two sentences "the best in the world/the best to eat" strengthen and deepen the theme. Because she came to a different place "alone", she had no relatives around, and no one could be her favorite hometown pie. Only she can cook this dish, which is of course "the best in the world"!

Reading this poem, we can think that in the cold winter, the poet is facing the snowflakes all over the sky in the house, making pies in his hometown, feeling homesick in the steaming heat, eating pies and deeply thinking about his loved ones. ...

The above poem profoundly illustrates this problem. When writing poetry, don't be professional, don't make up, don't impress others with flowery words, but don't be straightforward. There are deep feelings in the simple appearance, and the meaningful taste is lingering fragrance.
