Gansu Luqu staged 'Guozhuang'

In modern times the dance is only performed at festivals, ceremonies and weddings. Male and female dancers stand in a circle hand-in-hand and sing songs without musical accompaniment.

The song begins slowly and gradually speeds up. Men begin the singing and women reply in an antiphonal style. They repeat the chanting until arriving at the same upbeat rhythm.

It was honored as an intangible cultural heritage in 2006 when China issued its first nationally ranked cultural heritage sites.

The three-day event includes a bonfire party, Tibetan costume display and other activities.
