Tibetan folk dance has preserved alongside with the development of Tibetan religious culture. When religious rituals are held, these dances are often performed with high art. For example, during the Grand Summons Ceremony in Lhasa, monks from some monasteries perform for leading figures, monks and laymen. Picture shows the monks from the Gonggar Monastery in Shannan Prefectures performing a big drum dance. Dancers jump around while using an arc-shaped drumstick to beat a big drum on their back. The dancers' movements and postures are bold, unconstrained and easy (1957)
