Answer:
First, the original poem "Seven Laws Long March"
The Red Army is not afraid of expedition.
Wanshui Qian Shan is just idle.
Five ridges winding, blue waves rippling,
Wumeng is majestic, taking mud pills.
Jinsha water pats the clouds and cliffs warm,
The beams of Dadu Bridge are cold.
I prefer the snow in Minshan,
After the three armies, everyone laughed.
Second, the use of contrast to express the heroic poems of the Red Army
Five ridges winding, blue waves rippling,
Wumeng is majestic, taking mud pills.
Jinsha water pats the clouds and cliffs warm,
The beams of Dadu Bridge are cold.
By contrasting and describing the arduous and magnificent scenes of the Long March, these poems profoundly depict the Red Army's fearless psychological state and show the heroic spirit of the Red Army.
