NVDA meaning in Governmental ?

Chushi Gangdruk (Tibetan: ཆུ་བཞི་སྒང་དྲུག་, Wylie: Chu bzhi sgang drug, lit. 'Four Rivers, Six Ranges') was a Khampa Tibetan guerrilla group. Formally organized on 16 June 1958, the Chushi Gangdruk guerrilla fighters fought the forces of the People's Republic of China (PRC) in Tibet from 1956 to 1974.

The Dokham Chushi Gangdruk organization, a charity set up in New York City and India with chapters in other countries, now supports survivors of the Chushi Gangdruk resistance currently living in India. Chushi Gangdruk also led the 14th Dalai Lama out of Lhasa, where he had lived, soon after the start of the Chinese invasion. During that time, a group of Chushi Gangdruk guerillas was led by Kunga Samten, who is now deceased. Because the United States was prepared to recognize People's Republic of China in the early 1970s, CIA Tibetan Program, which funded the Chushi Gangdruk army, was ended in 1974.
