Literary works are primarily distinguishable from other pieces of writing by their creative or artistic content.

文学作品与其他作品的主要区别在于其创作或艺术内容。

So literary writing, having creative and artistic content, is more carefully structured and uses words for the rhetorical effect of their flow, their sound, and their emotive and descriptive qualities.

因此，具有创造性和艺术性内容的文学作品，其结构更为严谨，用词的修辞效果在于其流动性、声音性、情感性和描写性。
