Nangsa Lainchung 
Oath of Polungde 

The Oath of Polungde tells the vivid and striking stories of the evolution of an ancient big family in the Kham Tibetan region from the ancient "white wolf tribe" into a big chieftain family in the Kham Tibetan area, which happened in the course from thriving to decline. It can be regarded as a legendary history of yearning and sorrow of the wealthy and influential clan and men of Tibet.
