There were many touching stories about the Red Army climbing the snowy mountains. One of the stories was called " Triathlon." The triathlon meant that when the Red Army climbed the snowy mountain, everyone had to complete three tasks in order to save energy: running, swimming, and climbing. This mission was very difficult because each mission required a lot of stamina and each mission needed to be completed on different terrains. One day, the Red Army team came to a valley on a high mountain. They had to climb up the valley to continue moving forward. However, the valley was very steep and there were no roads or stairs. The Red Army troops had no choice but to start climbing. At this moment, a young soldier named Li Hua felt that he was lacking in stamina. He had tried his best to run, but he still felt very tired. He thought of his father, who had once served as a soldier in the Red Army during the Anti-Japanese War. He had once climbed countless snowy mountains. Li Hua decided to ask the other soldiers for help, hoping to get some help. When the other soldiers heard the news, they expressed their willingness to help Li Hua. Hence, they began to help Li Hua climb the hill. Li Hua was extremely grateful. He felt that he and the other soldiers had completed this mission together. Finally, the Red Army team successfully reached the top of the mountain and saw the beautiful scenery. Li Hua and the other soldiers were very excited. They felt that they had completed a great challenge. In this process, they learned to support and cooperate with each other, and they also cherished their lives more. This story tells us that we should help and support each other when we are in trouble instead of facing difficulties alone. At the same time, this story also emphasized the importance of teamwork and mutual trust.
