The research reveals that the traditional and natural way of spreading Wu-Yue folk sports is faced with inheritance crisis. Therefore, on the basis of protecting the "original ecology" of Wu-Yue folk sports, we should pay attention to the overall protection of Wu-Yue folk cultural ecology and innovate it from the content and function in order for it to adapt to the requirements of modern culture and to reshape the sense of cultural identity of regional culture. Such undertakings will surely result in a win-win prospect in protecting the cultural heritage of folk sports and promoting cultural construction of new countryside.
