During the Long March, the Red Army had climbed over 5000 meters of snowy mountains, including Mount Qomolangma. They also passed through a vast grassland known as the " grassland wasteland ". At that time, the Red Army had experienced a life and death test and had to constantly move and find food. During the Long March, the Red Army had gone through more than half of China for decades and finally reached northern Shaanxi to complete the Long March feat.
