Ex-hunter preserves ethnic skills in Tibet

Dawa is an ethnic Lhopa man living in the Tibet autonomous region's Manling, a county with a long history in growing medicinal plants and developing Tibetan medicinal science.

Surrounded by the snowcapped mountains of Nyingchi and with dense forests in the center - a lush, green land filled with fruit trees - the county is home to the small ethnic group of which Dawa is a part.

The Lhopas have been living in the Himalayan region since ancient times. Today it is home to more than 3,000.
