Questions about the Seven Laws Long March!

Wuling makes waves, and Wumeng takes mud pills;

Wuling mountain range is so ups and downs, endless, but in the eyes of the red army, it is like a small billowing spray; Mount Wumeng is as tall and majestic, but in the eyes of the Red Army, it is like a mud ball rolling under your feet.

The Jinsha River is warm in Boyun Cliff, and the Dadu Bridge is cold in lock bar;

On the cliffs on both sides of the Jinsha River, the rushing water beats against the towering cliffs on both sides, giving people a warm feeling (suggesting the cheerful mood of the Red Army after skillfully crossing the Jinsha River); The Luding Bridge on the Dadu River spans the east and west banks, leaving only a dozen iron locks, which makes people feel a deep chill (suggesting the thrilling and tragic flight of the Red Army over the Luding Bridge).

This poem expresses the poet's brave and tenacious revolutionary heroism and revolutionary optimism.
