Late Song Dynasty

The sun sets over the long river and the lonely smoke spreads across the desert. I have something to do with it. Why did I come to this ghost place inexplicably? The Southern Song Dynasty is about to fall. Who can stop the iron hoof of the descendants of Genghis Khan and endure the seizure of China and foreign barbarians? It will be very sad to look back on the world. What can I do? God, why am I here? You are fucking kidding me!
