Be careful of falling rocks on the mountain, everyone. If the wind is too strong, it is easy to blow down the broken stones. On Mount Muztag, Sergeant Zhang Lianjie of the Taherman Border Defense Company of the Xinjiang Military Region led a patrol team through two steep cliffs. He waved his hands to signal his comrades to pass quickly while observing the surrounding environment with alertness. Zhang Lianjie has traveled over 300 times on this exceptionally difficult patrol road. Every time, he dare not take it lightly. In 2011, Jet Zhang, who had been longing for military camps since childhood, did not hesitate to join the military after graduating from high school. Quickly, Jet Zhang, who usually works very hard, got the opportunity to patrol. On a plateau with an altitude of over 5000 meters, disregarding the impact of scarce oxygen, Jet Zhang eagerly climbed up. Suddenly feeling dizzy, he leaned aside and was about to fall off the cliff. The old squad leader following him grabbed his belt and pulled him back. From then on, Jet Zhang dared not show off his abilities. There is a kind of youth that guards the border, and there is a kind of love that has no complaints or regrets. Now, Jet Zhang has spent nearly 5000 days and nights at the Taherman Border Defense Company. He, who is just in his early thirties, has a history that is not commensurate with his age. Pieces of plateau red are distributed on the dark face, and the whole person is like a rock that has been polished by time, rough and firm. The soldiers all said that the squad leader poured all his love into the border, broadcasted it on Mount Mustag, and devoted it to his comrades around him. Every time a new soldier joins a platoon, there will always be some soldiers with weaker physical fitness who are not adapted to the cold climate, resulting in the phenomenon of "new soldier legs". In order to alleviate the leg pain of new recruits, Jet Zhang specially followed different military doctors to "learn" and gradually summarized a unique set of massage techniques. The new recruits said, "With the squad leader's' unique skill 'combined with his specially designed drop medicine, our legs will soon stop hurting." However, Zhang Lianjie rarely paid attention to his injuries. Spread out his hands, the cold scars big and small told the story of Zhang Lianjie's years of hard defense. That winter, the platoon received a task to install cameras in various mountain pass passages of the border defense line under its jurisdiction. Jet Zhang volunteered and arrived at a point in the most hostile environment. The cold wind mixed with the sound of ice and snow, the piercing cold eroding Zhang Lianjie's entire body. In order to complete the task before the specified time, he gritted his teeth and took off his cold gloves. "Pay attention to safety, the wind and snow are too strong!" My comrade shouted at Jet Zhang on the escalator. "The last surveillance, it's ready soon!" The heavy snow blurred Zhang Lianjie's line of sight as he struggled to identify the device in front of him. "Lao Zhang, it was too dangerous just now, and you fought too hard." As the mission ended, watching Jet Zhang's hands turn purple from the cold, my comrades were filled with heartache. During that mission, Jet Zhang's hand fell from the root of frostbite, and his finger joints always felt a faint pain when the weather changed. Despite experiencing many difficult days that are difficult to express in words, Jet Zhang believes that all of this has helped him find value. He occasionally flipped through some old photos and often expressed a feeling of "time flies and the sea changes". Mount Mustag is very beautiful, very close to the sky. Standing here, it feels like you can reach out and touch the clouds. In the evening, Jet Zhang sat on the hillside, his deep gaze cast into the distance. The evening light falls, as if for him
