In 2006, the Qinghai Tibet Plateau, known as the "roof of the world", ushered in a new road, the Qinghai Tibet railway, which was opened to traffic, connecting the desolate snow area with the prosperous inland. (special combat team members use parachutes for armed long-range penetration.) Two years later, the predecessor unit of the third squadron of the Naqu detachment of the Tibet Armed Police Corps was formally established. Since then, the officers and men of the squadron have been stationed in Tanggula Mountain, which is more than 5000 meters above sea level, and have been guarding this transportation line connecting happiness against the wind, snow and cold. Staff sergeant Tan Tingxing, who has been in the army for nearly 10 years, is now the oldest soldier in the squadron. He could not remember how many trains he had seen flying by on the patrol road. In order to ensure the safe return of trains, Tan Tingxing has been guarding this frozen plateau year after year. The siren sounds like a day for ten years. In the 138 kilometer "no man's land" from andor to Tanggula, the officers and men of the third squadron on duty patrol along the railway track again and again. In the past 10 years, the total patrol mileage was more than 1 million kilometers, equivalent to 35 and a half circles around the earth. As time goes by, the Qinghai Tibet railway has been operating safely for more than 5000 days. The superposition of each day reflects the fighting years of the officers and men of the squadron. Beside the railway, they witnessed the train speeding, the happy smiles of passengers and the rapid development of the times. The railway under the foot is the poem and the distant jade. Su Pu Ali ablimiti once again set foot on the familiar patrol road. The patrol car rocked violently on the rough road. This Uygur private soldier from Xinjiang was sitting in the car and was bumped like a rabbit. It is more than 5000 meters above sea level and 138 kilometers long. This is the railway line guarded by the third squadron of the Naqu detachment of the Tibet Armed Police Corps for 14 years. Although he had walked many times, Yu Su Pu Ai Li could not help but look out of the window of the car curiously. The mountains that could be seen everywhere seemed like continuous city walls, full of grotesque stones; From time to time, groundhogs come out of the ground and watch around with caution; Not far from the railway, a group of wild donkeys roamed freely in the wilderness looking for food. The scenery along the way is as far away as usual. Yu Su Pu Ai Li looked at the picture passing by the window and suddenly recalled his first trip to Tanggula Mountain a year ago. "When I first arrived at the squadron, I was excited and fresh because I had never seen so many mountains. I was curious and happy about everything in the squadron." Yu Su Pu Ai Li said, "unfortunately, this happiness did not last for a few days." During the first few days of patrol, my mother couldn't help asking him: "balangzi, what's wrong with your face?" "I was hit by the wind and snow in Tanggula!" Yu Su Pu Ai Li pointed to the skin on his face and replied humorously. That time, Yu Su Pu Ai Li and his comrades in arms went to the top of the mountain to check the communication base station. The mountain path is rugged, and the thickness of snow in some places reaches tens of centimeters. If you step on it, the heavy snow suddenly reaches your knees. The strong cold wind poured relentlessly into his mouth and nose, and Yu Su Pu Ai Li could not even speak. Around them, the endless snow reflected the dazzling light. On the clean snow surface, the light reflectivity can reach 95%, and the brightness is almost close to the sunlight. "My face was reddened and swollen by the intense ultraviolet rays, as if I had been beaten
