P. Coubertin advocated the spirit of modern Olympic which came from acient Olympic spirit, and its purpose was that all the sportmen around the world should be united to come true world peace. The spirit contributed to the growth of world peace and unity around the world until 100th anniversary of Olympic game. But the Ideal of Olympic spirit faded as times passed away, especially because the effect of commercialism on Olympic went to extremes. Each country considered the Olympic games as a means of instilling patriotism and showing off its power. It was also used ways of accummulation of wealth. Besider people focused on not the process of the Olympic games itself but the results of the games, and some players abused durgs to medals. As a result we lost the purd ideal of Olympic games. Now it ` s time we have to reconsider the spirit of Olympic. It will be grateful to make new Olympic history reborned with sound sportsmanship and ancient Olympic spirit.
