Couplets further exaggerate the tragic atmosphere from two aspects: sound and color. Horn blare, originally is a very sad voice; Now echoing in the bleak autumn, it is naturally more tragic. Start with the sound here. "Stuffing with fat to coagulate night purple" is a contrast in color. In the twilight, the walls with red borders are condensed in the twilight, showing a deep purple color, adding a tragic color to this tragic picture.
Original poem:
Yanmen Taishou Travel in Tang Dynasty: Li He
Enemy soldiers rolled in like dark clouds in an attempt to tear down the city wall; Our army was ready, and the sun shone on the armor, glittering with gold. (working towards the sun: working towards the moon)
In autumn, the loud bugle sounded; The soldier's blood became dark in the night. (Before filling: filling)
The red flag rolled half, and the reinforcements rushed to Xiao; The night frost is heavy and the drums are gloomy.
Just to return the king, sword and death.
Explanation:
Enemy soldiers rolled in like dark clouds, trying to destroy the city wall; The soldiers' armor shone golden in the sun.
The sound of the horn resounded through the autumn sky, and the clouds on the horizon beyond the Great Wall turned the night sky purple.
The red flag is half-rolled, and reinforcements rush to Xiao; The night is frosty and the drums are gloomy.
In order to repay the monarch's reward and love, he is willing to fight for his country to the death with a sword in his hand.
Extended data:
There are two versions about the age of this poem. One kind: This poem was written in 8 14 (Tang Xianzong Yuan and 9 years). At that time, Tang Xianzong took Zhang Xu as our time, and led the troops to quell the Yanmen rebellion. Li He improvised poems to boost morale and made this song "Wild Goose Gate". To put it another way, according to Tang Zhanggu's Advocating Leisure, Li He showed Han Yu a volume of poetry, and Han Yu appreciated it after reading it. It was in 807 AD (Yuan and two years).
One or two sentences about siege and breakthrough constitute a unit of meaning. The following eight sentences are written to pursue the victory until the enemy reaches Xiao, which is the meaning of another unit. Horn, an ancient military instrument. There is a record of "blowing the horn and withdrawing troops" in the biography of the northern history of Jiande Wang Yanzong. Looking at the context, the phrase "the horn is full of autumn colors" is based on virtual realism.
Show the magnificent scene of the enemy retreating and chasing in the reader's imagination. The word "night" in "blocking rouge and setting night purple" takes care of the word "day" in the first sentence, indicating that the breakthrough has been long, and the two sides are fighting each other.
"Put on rouge", the old explanation quoted in Notes on Ancient and Modern Times, "Qin built the Great Wall, so it was called Zisai", is generally good. It is tempting to see the blood of war by closely describing the red and purple of the earth with the sound of the horn and autumn colors. Adding a word "coagulation" before "purple" further strengthens this association.
From "day" to "night" or even "frost" in the middle of the night, the pursuers had already arrived in Yishui, and the enemy naturally arrived in Yishui first. The pursuers followed, and if the enemy wants to cross the water, it may be that the whole army will re-serve, so it can only be the last fight. At the thought of Han Xin's backwater array, I knew how severe the situation facing the pursuer was! It is a reflection of this grim situation that the drum can't afford to fight, and the Lord swears to death.
As for the result of a quick victory, let readers imagine it. Poets use special artistic techniques to express their unique artistic imagination, or use symbols, hints, or contrasts, or use virtual reality, sound visualization, and exchange parts for the whole, leaving readers with too broad imagination space, so readers' understanding varies from person to person.
