During more than 100-year Olympic history, many Olympic concepts have been endued new definitions in order to satisfy the updating demands raised from social reformation and development at global level. In 20th century, Olympic games were considered not only as a great opportunity for spreading great Olympic spirits, sharing ideas and ideologies, but also as a showcase of national comprehensive power. As a consequence, hosting an Olympic has been treated as great honor. However, in recent two decades of 21st century, Olympic seems to become a "hot potato", for some reasons, the interest of hosting Olympic Games has been decreased. Facing with this phenomenon, the International Olympic Committee(IOC) has to take actions to guarantee the Olympic continuity without lowering host requirements.
