Hardship and exhaustion did not make Lei Yaoming retreat, but instead stimulated his persistence and stubbornness in character. In the following days, he devoted himself to studying construction techniques on the construction site, and in his second year of service, he acquired the ability to independently carry out construction operations. After selecting Sergeant Jin, he became the class monitor and began to lead the homework. Once, the company formed an assault team to carry out a dangerous and important task. After receiving the order from the platoon leader to take a step forward as a party member, Lei Yaoming, who was not yet a party member at the time, took the initiative to step out. The platoon leader asked Lei Yaoming to return to the queue, and his chest puffed up. "I am the squad leader, and I should charge ahead for urgent, difficult, dangerous, and heavy tasks." The task was completed smoothly, and after returning to the team, Lei Yaoming submitted his application to join the party as soon as possible. Construction sites are battlefields, and construction is battles. ”This is Lei Yaoming's catchphrase. His comrades told reporters that no matter how complex or dangerous the work environment is, Lei Yaoming always sticks to the "most needed places". A certain construction task is in the critical stage, and there are frequent rockfall hazards on site. No matter how difficult or risky it is, we still need to tackle this tough nut and ensure timely completion. "With years of experience, Lei Yaoming carefully analyzed the on-site situation and organized the operation while observing. He didn't leave the scene for a single step in 13 hours. Dare to charge and fight, you also need to have strong skills. When Lei Yaoming first came into contact with the spraying operation on the construction site, the spraying pipes on the site were prone to blockage, which was a problem that troubled the officers and soldiers. To solve this problem, Lei Yaoming brought in books and devoted himself wholeheartedly to studying the principle of spraying. Half a month later, he proposed to the class monitor to spray ordinary mortar to lubricate the pipeline first, and then spray concrete slurry. After following Lei Yaoming's method of construction, the problem of blockage was effectively resolved. One year, after a mechanical equipment in the unit malfunctioned, it needed to be sent hundreds of kilometers away for repair due to a lack of maintenance personnel. Time is tight, tasks are heavy, and repairs come and go. How much progress will be delayed? Lei Yaoming decided to conduct his own research. During that time, he held the instruction manual and pondered over each component one by one, searching for the cause of the malfunction through comparison. Hard work pays off. He can not only eliminate major and minor faults, but also bring out two key maintenance personnel. Lei Yaoming's willingness to endure hardship and love for research has greatly impressed his comrades. First level Sergeant Zhang Junqiang said, "After coming down from the construction site, sometimes my comrades are so tired that they don't even want to eat and are all taking a break. However, Captain Lei has relied on his extraordinary perseverance to study new construction techniques and refine equipment maintenance skills
