The world of sports is full of competitions, although sport is a valued human practice. In recent decades, market values and nationalism have become a dominated power which influences the development of sports deeply. Therefore, conquering others is regarded as the supreme goal in contemporary sports. Under such circumstance, the world of sports becomes more and more competitive, and the ethics of sports is undermined by cheating, violence and aggression because of intense competitions. It is urgent to guard against the danger of blind subservience to competitions, and to find a way to escape from the cage. Self-transcendence is one of the best ways for sportsmen. Those who take priority to self-transcendence are usually concerned about the true meaning of life. This means that the philosophy of life will decide the attitude of sportsmen while taking part in competition. This paper aims to explore an awareness of "complete life" for sportsmen according to Taoist philosophy in ancient China. Taoist philosophy is profound and goes deeper into the way of life. From the perspective of Lao-tzu, mastering others is strength. He who conquers himself is the real strong man. Conquering others can't get the true meaning of life. If sportsmen wish to appreciate the happiness and wellbeing in competitive sports, turning to self-transcendence is the best choice.
