Chonga Lham and her friends from Chungkha village of Bongo Gewog (county) in Chukha district, perform one of the old Boedra songs called "Sharcho Gunthang La" (The Eastern Gunthang Mountain). This song makes an introduction to the mountain called Gunthang which is located in eastern Bhutan. As the song describes nature and it does not have any sad lyrics, it can be performed in all kinds of occasions, celebrations and gatherings. It is most of the time performed in a circular formation with around five to twenty dancers. The origin and the composer of the song remain unknown.
