What difficulties did the Red Army encounter when crossing the grassland in the Long March?

There are many difficulties for the Red Army to cross the grassland on the Long March. The first is the problem of food, the second is the problem of travel, and the third is to keep going in the face of cold or heat. The Long March of the Red Army was really full of difficulties, and many people died for it. The Red Army's Long March across the grassland is in Zoige, northwest Sichuan, belonging to the Qinghai-Tibet Plateau, with an average elevation of more than 3,400 meters. At this altitude, ordinary people will have difficulty breathing for a while, let alone for a long time.

At that time, people's conditions were not very rich. Many people can't even eat, and the Red Army's Long March is even harder. But if they want to cross this grassland smoothly, food is definitely indispensable, but food is simply not enough. Everyone can only bring about 5-6 kilograms of food. The Long March is a long process, which is definitely not enough. So they have to think of something else. Although they want to eat weeds and chew bark, they can't survive. Some weeds are poisonous, which will cause vomiting and diarrhea, and some will even die. Therefore, food can be said to be the biggest difficulty in the Red Army's Long March.

Secondly, travel is also a problem. Long distance is by walking, and the road is particularly difficult to walk. Sometimes you meet a swamp or something. Whether it can be passed smoothly is also a big problem. There are still many traps in the grass. The Long March of the Red Army can really be said to be one step at a time. Because of the high altitude, the weather here is very extreme, either very cold or very hot. People can't stand it at all. It's probably too hot.

Although it is difficult, although many people died in the process, they still persist and never give up. I think this spirit is always worth learning.
