From refugees to dead soldiers, we fought bloody battles to build an iron army; until the leader of Xianbei knelt down to present the seal ribbon and asked tremblingly: "What does the general want?" I pointed the horizontal sword outside the Great Wall: "Wherever my Han flag is planted, we must speak Chinese and observe Han etiquette——" "You bastard knights will never be able to take a step forward!"
