Life is like chess, if one piece falls wrong, the whole game is lost. Whether he is a traitor or a hero, he is just a fallen chess piece. You have no regrets when you make a move. You only know your regrets after you see your success or failure. See how Emperor Yang Guang of the Sui Dynasty and the scumbag father Yu Wenhua reversed the chess game and redeemed their past regrets.
