This mountain is more than 4500 meters above sea level and is covered with snow all year round. During the period from sunset to sunrise, the evil wind roared everywhere, and the snow was flying all over the sky, which was extremely cold. The mountain is so high and steep that birds cannot fly over it. The snow-capped mountains are so high that even Kuomintang planes can't fly. Red Army soldiers at the top of Jin Jia once saw planes hovering under their feet.
In addition to the cold, there is also lack of oxygen in the mountains. You must have enough winter clothes to climb the snow-capped mountains, and it is best to have shochu to keep out the cold. Unfortunately, the Red Army lacks both. There are few people at the foot of the mountain, so it is impossible to find cotton-padded clothes for 20 thousand people, and there are few shochu.
At that time, the officers and men of the army were not only in rags, but also mostly from Hunan, Fujian, Jiangxi, Guangdong and other places. They have never seen such a high snow-capped mountain, nor have they experienced the biting cold. The weather became colder and colder when the Red Army wearing a single coat crossed the snow-capped mountains. The commanders and fighters had to open the quilt in their backpacks, chew peppers and climb the mountain with strong political mobilization.
In the face of severe cold and extreme hypoxia, officers and men have to rely on the heat generated by their own exercise to drive away the cold. At this time, the red pepper has become a life-saving fruit for the Red Army to climb over the snow-capped mountains.
