1. Scenery description: Use the writing technique of combining movement and stillness, virtuality and reality.
The real scene description of the whole poem is in the first four sentences, including: Jieshi Mountain, calm sea water, small island in the sea, trees on the island, flowers and plants on the island, and waves blown by the wind. The characteristic of real scene description is from near to far, from stillness to movement. Such descriptive characteristics better highlight the poet's infinite imagination in the last four sentences of the poem, giving readers a more shocking ideological impact. The virtual scene described by the author is the sun and moon swallowed up by the sea and the stars like the Milky Way. The journey of the sun and the moon is like going out of it. The stars are as brilliant as if they came out of it. The movements of the sun and the moon seem to appear and disappear in the embrace of the sea, and the brilliant stars of the Milky Way seem to be contained in the mother's womb of the sea. It fully expresses the spirit of the sea and the mind of the sea.
2. Lyrical: Use exaggeration and association writing techniques.
The last sentence: "The journey of the sun and the moon is as if it is out of it; the stars are brilliant as if they are out of it." The poet unfolds his rich imagination here, using the ever-changing turbulent waves on the sea surface and the countless reflections on the water surface. There are thousands of dazzling light spots like the Milky Way, the sun and the moon seem to move in and out of the embrace of the sea, and the brilliant Milky Way stars seem to be contained in the mother's womb of the sea. Here, the majestic spirit and broad mind of the sea swallowing up the sun and moon, and containing stars and men are expressed in an exaggerated way. It makes us seem to see Cao Cao's great ambition and broad mind in forging ahead and determined to unify the country, and touch the flow of thoughts and feelings of Cao Cao as a poet, politician, and military strategist in a typical environment. The whole poem has simple language, rich imagination, majestic momentum, desolation and solemnity, which has been appreciated by readers of all ages. Shen Deqian commented in "The Source of Ancient Poetry" that this poem "has the atmosphere of swallowing up the universe". This is very precise.
