An American doctor has provided free medical treatment to rural people in the Tibet Autonomous Region for the past decade.
Nancy Tsang, 47, first came to China in 1990 as a tourist, and was moved by the poor living conditions and medical services for people in remote rural areas.
She decided to establish a foundation to collect funds for treatment, and has herself lived in Tibet for 12 years now.
Every year the foundation is able to treat 100,000 people free of charge. The doctor said she was planning to stay another 10 years.
