"January 3, 1889, Turin. Frederick Nietzsche stopped in front of door number 6 of the Via Carlo Alport Hotel. His eyes were attracted by a carriage outside the hotel. Not far away, there was a small carriage. The coachman encountered a stubborn horse. No matter how the coachman shouted, the horse had no intention of moving. Finally, the coachman lost his patience, picked up the whip and hit the horse. Seeing this, Nietzsche squeezed into the crowd, rushed to the horse, stopped the coachman, hugged the horse's neck and cried bitterly. The owner of the hotel came and took Nietzsche away. Nietzsche returned to the hotel and lay quietly and motionlessly on the sofa for two days. Then he whispered a few words. Next, Nietzsche was insane and crazy for ten years, and was taken care of by his sister and mother. No one knows what happened in Turin, on the horse, and in Nietzsche's mind."
