As night fell, the barracks of a certain brigade of the 77th Group Army remained silent. Some time ago, the peloton moved to the field training ground, and the busy camp in the past was much more deserted. As a sergeant who was about to expire his service, Corporal Zhang Haitao was not included in the company's list for field training, but was arranged to stay in the camp. This is also a common practice of many companies: the natural environment of the field training ground is poor, and the execution of tasks is heavy. The company will arrange for the injured and sick, as well as the retiring officers and soldiers, to be responsible for the remaining work. Zhang Haitao originally thought that the task of staying on duty was to stand guard on duty. However, this year's stay on duty was somewhat different - in terms of management, morning exercises, gatherings, and roll calls were also quite different; Engaging in training, maintaining physical fitness, professionalism, and tactics; In addition to being on duty, as a backbone of the water and electrical engineering profession, Zhang Haitao was also assigned the task of pipeline maintenance in the camp by the temporary left behind company... Although he was busy every day, Zhang Haitao felt very fulfilled and his originally lost mood was also lifted up. What are you busy with every day? "Zeng Cheng, the class monitor stationed outside the training center, called. Zhang Haitao smiled and said," Class monitor, this year's stay is different, and I won't be free at all. "Soon after, a notice was sent to the training center, and Zeng Cheng was also aware of what Zhang Haitao had done. A few days ago, the main water supply pipeline in the camp broke, and Zhang Haitao and his comrades soaked in mud overnight and repaired the pipeline. After research by the Party branch of the temporary left behind company, it has been decided to give Zhang Haitao a commendation once. Upon receiving this notification, Zeng Cheng excitedly said, "Our class's soldiers are just different. If we stay behind, we will still receive rewards!" In the early morning of a temporary left behind company's daily work, as the last transport vehicle drove away from a certain battalion area of the 77th Group Army, a left behind officer and soldier packed their backpacks and gathered from various points to the same barracks. In the coming period, these officers and soldiers will start collective life in the temporary left behind platoon, responsible for maintaining barracks facilities and carrying out duty tasks at various points in the camp. He Chaolin, an engineer from a certain battalion of the brigade, served as the temporary left behind company instructor. Before taking office, the leader of the brigade said to him in a long and focused manner, "This training mission is heavy, and it is impossible for the battalion commander to stay behind. You should consider staying behind as a rare practical opportunity." The words of the leader of the brigade made He Chaolin feel even more pressure. Not long after the establishment of the temporary left behind company, He Chaolin encountered some difficulties - the left behind officers and soldiers came from various companies and were not familiar with each other. When the duty officer Zhang Yi called the sentry to wake up and change his guard, he couldn't help but make a mistake: "The patrol list says that the next sentry is Qi Haining, but there are more than 10 beds in a class. Which bed is sleeping on Qi Haining?" Helplessly, the upright Zhang Yi had to turn on a flashlight and wake up his comrades one by one. Being disturbed by the good dream, several soldiers lost their temper on the spot. Coincidentally. The next morning at breakfast, a soldier had a dispute over the order of meals: some believed that the canteen duty officer had called the remaining officers and soldiers of their company to have meals first. How could these problems possibly occur in the old company? "After dealing with the sudden situation one after another, He Chaolin began to think," How should the temporary left behind company be managed? "The personnel roster often changes, and what should be done in daily management. Before the end of the day, He Chaolin continued to pick up the roster and do his homework seriously - sure enough,
