If I could give only one piece of advice to any person in history, that would be Hitler, who led the tragedy of the World War II. I would ask him not to attack France. After viewing the picture of the surfer during the World War II, I deeply sympathise the pity people and deeply hope that the world war would not have happened. If I have consoled Hitler, the people in France or even all over the world would have had a peaceful and happy life. Therefore, if I have the ability to advise someone in history, he would certainly be Hitler.
