What is "kyunglung"

Kyunglung or Khyunglung is a village in the Tibet Autonomous Region of China. Kyunglung Ngüka "Silver Palace of Garuda Valley", located southwest of Mount Kailash , identified with palaces found in the upper Sutlej Valley, was the capital city of the ancient kingdom of Zhangzhung. Many Tibetologists and theorists suggest that Kyunglung was perhaps what the Zhangzhung people called Tagzig Olmo Lung Ring.
