The significance of the whole poem of the Seven Laws Long March

The red army is not afraid of the expedition, and Qianshan is just idle. Wuling makes waves, and Wumeng takes mud pills. Jinsha River is warmer than Yunya, Dadu Bridge is colder than the horizontal iron rope. I like the snow in Minshan Mountain. After the three services, I will hit my face.

Explain directly in words:

The Red Army is not afraid of the hardships of long-distance expeditions, although Qianshan, thousands of miles away from its destination, is nothing.

In the eyes of the Red Army, the mountains that the Long March passed through were just small waves in a small river ditch, and the famous mountains on the Yunnan-Guizhou Plateau were just mud balls at the foot of the Red Army.

The Jinsha River is full of turbid waves, patting the towering cliffs and steaming; The cross frame of the dangerous bridge on the Dadu River is shaking the iron rope hanging high in the air, and the chill bursts. All this was broken by the Red Army.

What is even more gratifying is that everyone is smiling after stepping on the snowy Minshan Mountain.

-the heroism contained in it can only be understood in detail under the background of understanding history.
