The poet's feelings are pinned on the image of the ocean. The ocean in the poem has three connotations: the first layer is the ocean in memory, that is, the hometown of the poet. There is the sea water that raised the poet like milk, the sound of the waves like a lullaby, and the white light emitted by the waves. The second is the ocean in reality. "The waves rushed back and forth, and I saw the white light on the other side far away." The poet sighs at the sea by the sea and misses home across the sea. The third kind is the ocean in the poet's mind, which is transformed from the first kind of ocean, invisible and intangible, and can only feel "rippling on my chest". A poem can accommodate the images of three oceans, which shows that this poem has a large capacity and is worthy of being a poem about the oceans.
These three oceans are like three pearls, but they are not isolated or mutually exclusive. What connects them is the golden thread woven by the poet's rich imagination and deep feelings. Belinsky said: "In poetry, imagination is an important active force, and the creative process can only be completed through imagination." This is because imagination is not dominated by whimsy, but a kind of "wandering between god and things." It must be based on real life, with a starting point, a landing point and a logical relationship of ups and downs. The second ocean in poetry, the ocean in reality, is the material basis for the poet to develop association. The poet couldn't help homesick when he saw the waves "rushing away". The image of hometown and the first ocean appeared in my mind, which fully expressed the poet's homesickness. Because of this strong and persistent yearning, the hometown in spirit likeness is naturally engraved in the poet's heart, and the second ocean has become the third ocean. The yearning for hometown has changed from a temporary memory to a permanent memory. Poetry here, the poet's homesickness has been further reflected, reaching the point of unforgettable. The poet's imagination, starting from the sea and ending at the sea, is inseparable and integrated into one, forming a world of the sea. The poet's deep affection for his hometown, his love, his yearning and his memories have all turned into the vastness, profundity and eternity of the sea.
