Jackie Chan is 70 years old now. He used to be a tough guy who could jump around and do anything. Now he is a white-haired man in his seventies, but his heart is young. He still releases works every year. He once said, "I will not retire. As long as I can move, I will do my best to the end. If I fall down, I will fall down on the stage instead of in a hospital bed. Jackie Chan's professionalism is worthy of learning for our younger generation and he is our role model.
