I'm looking for a positive, simple and good dance.

The Korean dance "Hope" and "Ballad of Kratom", the Tibetan "Gesang Meiduo" and "Kangding Love Song", and the Mongolian "Top Bowl Dance", "Going to School", "Grassland Daze", and "Rushing". They're all so easy, we learned them in the first semester. You can check out the videos on Tudou.com. Good luck!
