Mongolian dance steps are not based on T-step, and the hind feet move backwards. On the basis of T-step, the knees are close together, and the hind foot is extended and flexed, which can be divided into two types: extended foot and semi-hooked foot. Witches of ancient shamanism danced in white robes and held white silk towels. Until 1950s, Diane (also called Chagan Elie), an ancient dance form, was still popular among Mongolians.
