A long time ago, an imaginative king built an amphitheater, but what people saw in the arena was not a duel between people, nor a duel between people and beasts, but the fate of people. The king's daughter fell in love with a young man, but the law stipulates that civilians are not allowed to fall in love with the princess. After the romance was discovered, the king decided to let young people open the door in the arena and let fate decide the life and death of young people. Behind two doors is a beautiful woman and a tiger. The young man's choice means either marrying this beautiful woman or being torn apart by a tiger. The princess didn't want to see the bloody scene and was jealous of the beautiful woman behind the door, but the young people believed the instructions given by the princess and what kind of decision the princess would make. The story is full of suspense and the picture is very rhythmic, which is very suitable for children to read.
