This poem depicts the tragic and tragic battle scene with rich and mottled colors, and accurately and vividly shows the frontier fortress scenery and ever-changing war situation at a specific time and place. Li He writes poems and works hard on color setting. Lu You once said that his poems were "colorful, making people afraid to be familiar."
The enemy troops rolled in, and the sky was dark, like a dark cloud, which almost destroyed the city wall; Our army is ready to go, the sun shines on the armor, and a golden light flashes. In the cold autumn, loud trumpets shake the earth; In the cold night, the blood of the border guards condensed into deep purple. A half-rolled red flag, reinforcements rushed to Xiao; It's freezing in the cold, and the drums seem to be forced by the cold and depressed.
Generally speaking, it is not appropriate to use colorful words to describe the tragic and tragic battle scenes, and almost every sentence of this poem by Li He has bright colors, such as black, gold, rouge and purple, which are not only bright, but also rich in colors and intertwined to form a colorful picture. A poet, like a talented painter, is particularly good at coloring, expressing things with color, and touching people with color, not just sketching the outline.
