[Photo/Xinhua] On the evening of July 10, 2016, a mortar shell hit an armored vehicle amid a fierce exchange of fire between government and opposition forces in Juba, the capital city of South Sudan. Inside the vehicle were two Chinese peacekeepers on duty to protect some 9,000 civilians in downtown Juba and surrounding villages. Li Lei, a young soldier who had just celebrated his 22nd birthday, was killed alongside Sergeant Yang Shupeng, father of a 5-year-old 5,000 miles away from home. The two were awarded the United Nations' Dag Hammarskjöld medal for their sacrifice.
