This video is a narration of ballad that has two different interpretations. According to one interpretation, the ballad spread during the arrival of the sixth Tali Lama, Rigzin Tshangyang Jamtsho from Tsang in Tibet, and thus called གཙང་མོ་ (Deviation of Tsang). A second interpretation claims that the ballad is sung to seek fate of one self by using a thorn, thus is called རྩང་མོ་ (Divination of twig). Ballads are sung to for boys and girls to compete in capacity and knowledge. Ballads are of different sub-genres such as antagonizing tsangmo, befriending tsangmo, laudatory tsangmo, deprecating tsangmo, joyful tsangmo and so on. People even compete with one another while working in field or grazing animals.
