Longda is a product of the primitive Benbo belief to worship and sacrifice for natural gods, as well as one of the main sacrificial ceremonies of Tibetan Buddhist religion. Longda has two kinds, made of paper or cloth respectively, on which patterns and scripture writings are printed. The paper Longda is set free in winds; the cloth ones are stringed together with a rope, being hanged on bridges, sacred hills and Yaze sites.

Tibetan religious believers set free Longda to pray for blessing and auspicious time. The 6-character or 8-char acter incantation is printed on Longda and said to be of boundless magic power.
