Hou Changling, a National People's Congress representative and a second level sergeant of a certain brigade of the Rocket Force, stands in close view of the toughest "steel" Hou Changling on the tip of the knife. Wang Yumeng formed a formation with his long sword, filled with smoke and gunpowder. In spring, a simulated launch training is being conducted intensively at a field training ground of a rocket army brigade. Hou Changling, a National People's Congress representative and a second level sergeant of a certain brigade of the Rocket Force, focused on checking parameters and measuring routes. After a series of skilled operations, the launch proceeded smoothly according to the process. In the 21 years since enlistment, Hou Changling has participated in more than 10 major training missions and thousands of operational training sessions on safety assurance. In multiple launch missions, Hou Changling served as a "soldier expert" to provide technical guidance and witnessed missile launches. "The weapon of a great country is the sharp edge of a nation. We must be the hardest 'steel' on the tip of the sword!" Hou Changling grew and refined on the front line of military training and preparation. That year, the military entered a critical period of equipment replacement. As one of the first batch of personnel to learn new equipment, Hou Changling felt honored and deeply aware of the heavy responsibility. He and his comrades first went to the manufacturer to learn how to operate new equipment, and then led a team to train special equipment drivers, almost busy every day. In order to achieve the goal of "training without equipment and fighting with equipment", Hou Changling learned how to operate and use equipment while researching the production of simulated training equipment. The manufacturer provided a large stack of professional materials and more than ten schematic diagrams, which he quickly flipped over to the edge. After several months of polishing, they developed a set of simulation training equipment, which effectively improved the quality and efficiency of training. In recent years, Hou Changling has continuously innovated training methods to shorten the distance between training and actual combat. That time, the brigade went to an unfamiliar area for training when a device suddenly malfunctioned. Hou Changling resolved the problem in just a few minutes, ensuring that the training proceeded smoothly. A few minutes of obstacle clearance, ten years of hard work behind the scenes. In order to master the professional skills of "one word clear" and "one touch accurate", Hou Changling has put forward higher requirements for himself - to master the operation of all the numbers in his unit, to write each plan as a practical exercise, to check each number as a practical launch, and to strive to complete each task with the highest standard. As the head of a class, Hou Changling deeply understands that "a single flower is not spring, and a hundred flowers bloom together to fill the garden with spring". He pays attention to doing a good job of mentoring and mentoring in his daily life. In order to cultivate urgently needed talents in the military, he explored the talent cultivation path of "master guidance, job training, task promotion, and training assistance" in daily training, and led dozens of professional and technical elite soldiers. His class was honored with collective third class merit six times. On the training ground, Hou Changling was riveted under the launcher, closely monitoring the weaknesses and weaknesses of his unit, leading the trumpeter to launch a specialized attack and hone his winning skills. During the training break, Hou Changling and his comrades sat together to chat and exchange ideas. "As a representative of the National People's Congress, I will solidly conduct research, listen to the voices of my comrades, bring everyone's suggestions to the meeting, and fulfill the sacred duty of a National People's Congress representative," Hou Changling said.
