"The way to the post is blocked by the heavy snow. We can't get on! We are still contacting the municipal department." At the end of the phone is an officer of a border brigade of the army, who is decisive. "There must be a way. Our medical team has been on this line for decades, and we haven't seen anything!" At the end of the phone, Jiang Wansong, president of the 963 Hospital of the Joint Service Support Force, spoke in a low voice and a serious tone. "That is an isolated post, with only one squad stationed there." The officer changed his words and tried to persuade Jiang Wansong. "Even if there is only one sentry, we will go." Jiang Wansong hung up the phone. One day, the temperature was minus 40 degrees Celsius. When the medical team boarded the car, the sun was dazzling, and the air was sucked in, pressing the chest. Yang Qingyu, director of the Respiratory and Digestive Department, finished his breakfast early and had been waiting downstairs for a while. Countless times, Lao Yang took his bag and medicine chest and said to go. Before being transferred to the hospital, he was the platoon leader of the border defense company. The platoon leader can also see people, which is rare. Who wants to be short of both cadres and doctors at that time! There is no way. Lao Yang, who is a medical professional, works as a platoon leader and medical assistant after enlistment. For more than 20 years, Lao Yang has never been left behind in the annual inspection tour. The young military doctor asked him what he felt about the patrol. He said that the road is too far, and thousands of kilometers of border lines often take five or six hours to sit on the bus. I am not afraid of the long journey, even if there is an accident on the road. In summer, the swollen river will flood the roads into the mountains. In winter, the roads will be buried again by the snow. One winter, the car sped past a ditch. After a violent jolt, the rear windshield was unexpectedly broken. On the way to the visit, the cold wind was pouring into the car, and everyone was shivering with cold. This time on the road, everything seemed smooth and safe, but Lao Yang's heart was more and more tense. As soon as you enter the mountain area, the overlapping mountains are reflected in front of you, the white land is covered with dense forests, and the vast snowfield is endless. The first stop of the medical team is the company headquarters. The company is stationed in a deep mountain forest, next to the frozen Heilongjiang. Huge ice cream, densely embedded on the ice surface, like a protruding sharp blade guarding the boundary river. Although the road conditions leading to the border guard company have improved a lot in recent years, and the municipal department will timely clear the snow in winter, some isolated outposts will occasionally be blocked in three or nine days. One by one, the driver was an experienced teacher specially found by the hospital. Although the road conditions are good, he dare not take it lightly. But even if the speed was not fast, the car almost had an accident when it was going downhill for five or six kilometers in a row. It was a curve, with rutting marks crisscrossed on the hard snow. The tyres creaked as the car passed. After turning the corner, a steep slope suddenly appeared, with large pieces of residual ice on the shady road. When the car was walking on it, it immediately refused to obey, and it shook left and right and then rushed down. The driver immediately put into the first gear, firmly held the steering wheel, slowly stepped on the brake, and finally stopped in front of a curve not far away... The car went along the snow
