Could the small court of the Southern Song Dynasty, which was in turmoil, change history? This book recreates the contrast between history and reality. Can the unknown boy ride a thousand miles, draw his bow to full length, and shoot an arrow? Can the sun and moon be reopened? Can conquering the east and west change history? Successful and famous, I look back blankly, but I don't know where I came from. Should I stay or leave?
