Liu Huibo, the first level sergeant of a certain technical team of the Navy in the Northern Theater Command, has been in the military for 28 years. The theme word for a veteran's unwavering sincerity is "pure". The Xinhua Dictionary explains it as "pure" and "not mixed with other elements." When it comes to the "pure" of a soldier, it is easy to think of four words: main responsibility and main business. The main responsibility of soldiers is to prepare for war. Specifically for each individual, it is the wholehearted dedication to their job position, the pursuit of excellence in professional skills, the exploration and exploration of unknown fields, and the infinite pursuit of winning and winning... Only with purity can one be determined, and only with determination can one know the importance. A "pure" soldier, without the need to whip himself, is solely focused on building a strong army. After crossing mountains and mountains, I don't know how many turns I have taken, but the car finally stopped on the empty ground in front of a technical team's warehouse in the Northern Theater Command Navy. As soon as I got off the car, I couldn't wait to find the interviewee for this interview - First Class Sergeant Liu Huibo. Looking around, I saw several soldiers squatting in front of the gate painting, but I couldn't see Liu Huibo. "Excuse me, where is Liu Huibo?" the author asked loudly. "I'm here!" A figure suddenly stood up and wiped the paint stains on his face with his hand as he walked. As Liu Huibo gradually approached, the author couldn't help but be surprised: a first-class sergeant who had been in the military for 28 years still did such miscellaneous things? "Come on, come in and sit down!" After a brief greeting, Liu Huibo greeted us as we walked into the cave, just like greeting a visiting guest at home. Before interviewing Liu Huibo, the author heard from the cadres and soldiers of this technical team that he is easy-going and friendly to people, "without any airs of a first-class sergeant.". New recruit Zheng Zhekai added, "Every time he sees us, squad leader Liu warmly greets us." However, the approachable "squad leader Liu" in daily life, once he enters the working state, is like a different person. "Liu Huibo treats soldiers very purely. In his work, he is serious and calm, without rubbing sand in his eyes, and only wants to do the things at hand well in his heart." Team leader Li Shupeng said that an incident that happened last year left a deep impression on him. At that time, Liu Huibo was selected by his superiors to support a certain task. In the preparation stage, a certain type of equipment suddenly malfunctioned. After inspection by the technical personnel sent by the manufacturer, they concluded that "it needs to be returned to the factory for repair." The leaders present frowned upon hearing this: the task is imminent, and there is no time for the equipment to be returned to the factory for repair! "Let me take a look." A voice came from behind everyone, and Liu Huibo walked out of the crowd with a serious expression on his face. Without saying a word, he began to inspect his equipment. A few minutes later, Liu Huibo came to the conclusion: "It's a small problem." Immediately, he started troubleshooting and the equipment quickly returned to normal. Afterwards, some comrades reminded him to pay attention to his speaking skills and propriety, and to consider the feelings of the manufacturer's technical personnel. Liu Huibo shook his head and said, "One code is one code. Don't complicate simple problems. Why do you think so much?" It was heard that Liu Huibo overturned the judgment of the manufacturer's technical personnel on the spot, accurately found the fault point, and successfully eliminated it. Wang Qingwei, the second level sergeant of the team, was not surprised at all. He was a disciple personally brought out by Liu Huibo, and the two fought side by side for 24 years. "He has a clear understanding of the five organs, six viscera, and eight meridians of the equipment," said Wang Qingwei. "In the technical team, who encounters professional problems?",
