The origin of "Hu Xuan Dance" can be traced back to the Han Dynasty, and it was introduced into China from the Western Regions and the Central Plains via the Silk Road.

After the Anshi Rebellion, musicians from Hexi, Longyou, Hedong and other places fled to Chang 'an, bringing all kinds of western music and dances.

In "Three Wan Li in Chang 'an", the performance form of "Hu Xuan Dance" is mainly women's solo dance or duet dance. The dancers wear light clothes, hold ribbons or wave sleeves, and rotate, jump and move quickly. With the change of music rhythm, the dance posture also changes.
