Phurbu T. Namgyal, a Tibetan pop star, has produced a series of short videos designed to teach Tibetan to children. Each story contains a nice moral. In fact, they are very helpful for anyone who is trying to learn colloquial Tibetan. The cartoons can be enjoyed on YouTube – click Videos. (with English subtitles!).
Phurbu T. Namgyal’s website has the lyrics in Tibetan for several of his songs as well as a section for children. Namgyel is known both for his music as well as his efforts to preserve Tibetan culture and to raise awareness about the plight of the Tibetans.
