In early spring, the cold wind whistles on the snowy plateau. A new type of assault vehicle tactical drill is in full swing on the training ground of the "Three Tigers", a battalion of the Red Army Corps of the Xinjiang Military Region. Company commander Liu Wei led the officers and soldiers to carry out shooting during the march, and multiple targets were "destroyed". "To practice the spirit of Lei Feng, for the officers and soldiers of our combat forces, it is necessary to stay in the battle position and train their fighting skills." When they stepped down from the assault vehicle, Liu Wei said, "Only after repeated training can they forge sharp knives and sharp blades." Liu Wei is the representative of the "Three Tigers" officers and soldiers to learn from Lei Feng based on the battle position. Over the past ten years, he has grown from an ordinary soldier to a company commander. He has done his job, loved his job, specialized in his job, and excelled in his job; When the platoon leader, he participated in the "International Military Competition-2017" "Safety and Environment" project competition, and led the fleet to win the gold medal of the project as the vehicle commander; As the vice company commander, he participated in the "International Military Competition-2019" "Security and Environment" event as a coach and led the team to win the gold medal in the event again. At the beginning of Liu Wei's appointment as company commander, it coincided with the adjustment and reform of the army. He and the members of the company's party branch led the officers and soldiers to start a new charge. During that time, Liu Wei carried forward Lei Feng's "nail" spirit, led the establishment of several research teams, constantly explored and studied, thought and summarized, and gradually found out the performance of new equipment. He took the lead in improving his versatility and mastering many professional skills such as chemical defense, sniping and driving. He was recognized by the Army as the "four haves" revolutionary soldier pacesetter in the new era, and was honored as the representative of the 14th National People's Congress. On the way back to the camp after the drill, Liu Wei talked freely and learned from Lei Feng's sentiment: "On the new journey, I will always practice the oath of loyalty, dedication, strength and strength, and let Lei Feng's spirit glow with the glory of the new era."
