This poem seems to be about horses, but in fact it is lyrical. The poet sighed because he was eager to make great achievements for his country, but he was not appreciated. This article writes that a good horse is famous for its vast border, so it can go forward bravely and only know its name. The word "he dang" expresses hope. In the era when Li He lived, there were frequent wars in the buffer regions. The author uses a famous horse as an analogy, saying that although he is born with talent, he also has a place to use, but he still needs to cherish his talent. This is the basic intention of Li Hema's poems. In his short life, Li He has always cherished the heart of making contributions. To this end, he even preferred to join the army. But this ideal can never be realized, so there is always an air of sadness and indignation in his poems. Generally speaking, the expression of Ma Shi's 23 poems belongs to metaphor. However, this poem has unique significance in the use of metaphor. The first sentence and the second sentence show the unique frontier battlefield scenery. At first glance, it is the application of fu method: on the continuous Yanshan mountains, a bright moon is in the sky; Wan Li in Pingsha looks like a layer of white frost and snow in the moonlight. This ordinary person may only feel sad and cold battlefield scene, which has unusual attraction for those who are determined to serve the country. The Moon in Yanshan Mountain is Like a Hook, and Xiao Yue hangs a jade bow as a curtain (the sixth in Nanyuan). "Hook" is a machete, and both are weapons. It is associated with the image of weapons from the bright crescent moon, which means thinking about fighting. Zhenyuan, Yuanhe period, where the author lived, was a period when the buffer region was extremely domineering, and the Jimen area in Youzhou implied by "Yanshan Mountain" was the zone where the buffer region ravaged for the longest time and caused the most disasters, so the poems were quite realistic. Thinking about war is also targeted. Sha Xue's flat battlefield is chilly, but it is a place where heroes can play. So these two sentences are lyrical and tangible. Three or four sentences: when can I put on a mighty saddle and gallop on the battlefield in the crisp autumn to establish meritorious deeds? "Ma Shi" says: "The dragon's back is tied with iron, and the silver hoof is covered with smoke. No one tapestry, who is the golden whip? " The lament of "no one has brocade" and "what should I do" To express the same meaning is to hope that a good horse can be used as a good horse. "Golden brain", "brocade" and "golden whip" all belong to precious saddles, symbolizing the importance of horses. This is the cry of the author who is eager to make achievements but is not appreciated. This poem and "South Garden (Why Men Don't Take Wu Gou)" are the same desire to join the army, pacify the provinces and make contributions to the country. But South Garden is a direct expression of the soul, and this poem belongs to allegorical or figurative style. It is more exciting to express one's mind directly; And with contrast, you will feel elegant and intriguing. In one or two sentences of the poem, it is also a comparison to use snow as a metaphor for sand and hook as a metaphor for the moon; It is also fun to write from a characteristic scenery and lead to lyricism. In a short span of twenty crosses, we can see the interest in comparison, and there is a ratio in interest, which greatly enriches the expressive force of poetry. Syntactically, the last two sentences are completed in one go, starting with the question "What should I do", which strongly conveys infinite expectations and has a sigh; The word "Step in the Clear Autumn" is full of vigor and novel collocation. It is covered with "clear autumn" grass and yellow horse fertilizer, and it is only driven by the word "go quickly". The image implies the graceful charm of the horse, which is just right: "Nothing wants and nothing wants, it is really worth life and death." Xiao Teng has this kind of behavior, and ten thousand run amok "(Du Fu's Fang Bing Cao Huma). Therefore, the practice of choosing words and making sentences is also a successful factor that can not be ignored in the artistic expression of this poem. Main idea of the poem: In the Yanshan desert (intertextuality here), the moon is like a silver hook, and under the moonlight, the dust is like snowflakes. When can I ride my armored fast horse and gallop freely in the clear autumn?
