During the holiday period, the 14th batch of Chinese peacekeeping engineering detachment officers and soldiers stationed in South Sudan (Wau) held their positions. In South Sudan, thousands of miles away from their motherland, they repaired their equipment, eliminated faults, and tirelessly strengthened their defense, putting in hard work and sweat in their respective positions. In a high temperature environment of 40 degrees Celsius, soldier Zhang Mengdi painted the vehicle's equipment. As a repairman, He Guangming's fingers are often covered in oil and mud, and his dark palms troubleshoot equipment malfunctions one by one. These hands are ordinary and ordinary, but they are a true witness to a soldier's struggle in his post. Corporal Lin Zhencai participated in peacekeeping missions in his third year of service, and he particularly cherished this hard-earned opportunity. As an equipment operator, he takes great care of his equipment vehicles. After rectifying and eliminating equipment malfunctions, Lin Zhencai showed a happy smile. At the same time, the security squadron closely followed the security situation in the task area and organized an emergency defense drill in the camp to strengthen the combat readiness awareness of officers and soldiers and enhance emergency capabilities.
