"Poetry" represents the aesthetic feeling and emotional expression of literature and art, while "distance" symbolizes the unknown world, the possibility of the future and dreams and longings beyond reality. This word can be traced back to a sentence in the poem "Facing the sea, spring blossoms" by the modern poet Haizi: "I have a house facing the sea, and spring blossoms." Later, this sentence was widely spread and quoted, and gradually evolved into such a poetic and imaginative concept as "poetry and distance".
