The original ethnic dance has been developed for a long history, which is the living material for us to learn our ancestor's culture. By comparing the ancient and modern culture, we may find out the trend of cultural development and changes. The original ethnic dances are very valuable to minority peoples. On one hand, it brings mental happiness and strengths cohesion within their groups. On the other hand, it is a good way to pass on ethnic minority's culture to offspring. In ancient society, dances couldn't be separated with the religious activities and sacrificial ceremonies. For example, the drum dance was used to present in the history, when someone died.
The original ethnic dance is the living fossil of ancient culture. In our research, we find that it is dying out. We can just recognize our ancestors' life from other cultural relics. It has become a serious problem for us to consider how to protect ethnic culture.
