The western plateau has less than half the oxygen content of the plain. In this' forbidden zone of life ', the antenna of a high-altitude radar station of the Western Theater Command Air Force rotates day and night, and a group of young officers and soldiers watch over the sky of their motherland with their youth. Not long ago, the wind and snow almost isolated this place into an island. However, waves of warm currents surging from all directions across thousands of mountains and rivers, let the frozen battlefield feel the abundant "spring atmosphere" in advance. That day, the transport vehicle was parked at the entrance of the camp. Second level Sergeant Meng Mingtao has been stomping his feet and waiting in the cold wind for a long time. The car door opened and his wife Huang Xin wrapped herself tightly and jumped down. Traveling from my hometown in Guangxi for 4 days, covering thousands of kilometers. As the altitude increases, Huang Xin experiences motion sickness, headaches, difficulty eating, and even difficulty breathing. Whenever Meng Mingtao calls, she just says, "I'm fine, don't worry." Walking into the dormitory, Huang Xin ignores her altitude sickness and quickly unties the woven bag she has been carrying all the way: "Your favorite fragrant pig, hemp, and oily fish made by our mom..." Soon, the table is filled with delicious food from home and town. Looking at the red mark on his wife's hand, Meng Mingtao, a man who never blinks in the face of complex emotions, his eyes instantly heat up. At the reunion dinner, the fragrant pig was sliced thinly, crystal clear; The oily fish was placed in the center of the dining table. Huang Xin walked into the kitchen and personally cooked one specialty dish after another. Meng Mingtao smiled happily at his wife. He knew that the fresh fragrance on his tongue was the "taste of home" prepared by his wife for him. At the Spring Festival event, Meng Mingtao performed magic on stage. He flipped his palm and a heart-shaped stone from the Karakoram Mountains appeared in his hand. He solemnly handed the stone to his wife, saying, "This stone has gone through wind and rain, just like my original intention of guarding. Today, I am giving it to you, please continue to support my work, I will guard our country, and you will guard our home..." The deep affection of home and country echoes in the plateau, and the love from afar is never absent. Not long ago, the "hot pot gift package" specially customized by the Air Force of the Western Theater Command arrived at the radar station in the face of wind and snow. At dinner, Sichuan soldier Zhang Wenjie smelled the aroma of spicy hotpot and danced with joy. Shandong class monitor Zheng Jiapeng originally didn't eat spicy food, but this time he was sweating profusely: "In this hotpot, I tasted a sense of being cared for." The warmth of hotpot has not dissipated, and new concerns have arrived. In the cultural and sports activity room, several cardboard boxes sent from Shanxi contain unexpected surprises. At the moment of opening the box, Private Li Honghao let out a cry of surprise. Besides Shanxi specialties, what moved the young men the most in the box was the stack of letters pressed at the bottom of the box. The signature on the letterhead is "Third Grade of Jincheng Third Primary School". The children's handwriting is very immature, and some even carry pinyin: "Uncle of the People's Liberation Army, Mom said you are guarding the blue sky of our country on the snow capped mountains. I want to send warm babies, but the post office says it can't be sent..." The soldiers sat in circles, some reading aloud, while others listened quietly. At the end of the reading, no one spoke anymore, only the wind outside the window was whistling. Second level Sergeant Fu Haibo carefully smoothed the creases on the letter and whispered, "My daughter is also in third grade. Seeing this letter is like hearing her talking to me." In order to send a blessing to the children, the officers and soldiers decided to take a family photo. The instructor pressed the shutter button, and after a few minutes, the photo slowly came out of the printer. Li Honghao held a photo with a slight warmth and smiled like a child. A stack of group photos passed through the hands of the soldiers, with sincere blessings written on the back of each one. Third level sergeant Li Zhanbo wrote, "Although the plateau is difficult, the mission is even heavier. We do not have to work hard to stand guard for our motherland
