Characterized by describing colors, poets write the colors of various scenes in detail, and make the colors set off each other, making them more vivid. Judging from the whole poem, the first two sentences are about writing sadness in musical scenes. When the spring is about to die, the poets who travel far have already missed their hometown. Seeing such colorful scenery more and more reflects the poet's loneliness, which is more likely to resonate with readers and enhance artistic expression.
