Sa: Metaphorical difficulties.
Mountain climbing: a metaphor of hard struggle
This poem expresses a belief and a philosophy. Poets take mountains and the sea as images, the sea as ideals, mountains as difficulties and climbing mountains as metaphors of hard struggle, with magnificent images and rich meanings. A word "mountain" can refer to either a mountain or countless mountains. From an artistic conception to a new artistic conception, poetry advances in ups and downs, and feelings are also ups and downs, which gives people profound enlightenment.
On the surface, the discovery of "beyond the mountain or beyond the mountain" is nothing more than the disillusionment of such naive illusions as "beyond the mountain is the sea". However, the "mountain" in poetry is a barrier that prevents the poet from reaching the "sea" he yearns for, and it is a realistic existence that prevents his dream from realizing. Therefore, this sense of frustration also indicates all the pains and failures in the poet's life, transcending the specific life experience and becoming a symbol of universal emotional experience.
Correspondingly, the "sea" symbolizes the tempting desire that always calls us to start: "On the other side of the mountain, it is the sea/the sea that embodies faith"; The snow-white tide comes every night/wets my dry heart again and again. The poet believes that "you will eventually reach the top of this mountain/and on the other side of this mountain is the sea"; This "sea", "is a brand-new world/brightens your eyes in an instant"!
