Rebuilding the Empire

No one knows where I come from, no one knows why I came here, the reason for others to know me is that I wash away the national humiliation and regain the lost ground. When future generations of experts open the book, they will find that the Song Dynasty was so great. When people of later generations go abroad, they will discover that the Chinese are the best nation in the world and the best among people. It doesn't matter if others don't pay attention to me, because I just want the Chinese to stand in this world forever. Anyone who offends China will be punished no matter how far away I am.
