What does it mean that "Jinsha water hits the clouds and cliffs warm, and the cross rail of Dadu Bridge is cold"? What do you mean by "warm clouds and cliffs"?

Warm Cloud Cliff: Warm Cloud Cliff, the cliffs on both sides of the Jinsha River. The rushing water slaps the towering cliffs on both sides, giving people a warm feeling (suggesting the joy of the Red Army skillfully crossing the Jinsha River).

This sentence comes from Mao Zedong's Seven Laws and the Long March. The Red Army is not afraid of all the difficulties and hardships on the Long March, and regards Qian Shan as ordinary. In the eyes of the red army, the continuous five mountains are just the ups and downs of microwave waves, and the majestic Wumeng Mountain is just a mud pill.

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. What is more gratifying is that when we set foot on the snowy Minshan Mountain, everyone was smiling after the Red Army crossed it.
