Changeable clouds, towering gorges and mysterious rivers, the Dulong River Valley is an isolated world hidden on the border of northwest China's Yunnan Province and Myanmar.

The Dulong River Valley in Gongshan Dulong and Nu Autonomous County, Yunnan Province is considered a natural botanical museum for its unspoiled primitive forests.

As the vast mountain ranges block the valley from the outside world, wildlife such as takins can be seen roaming freely along the river. And the ancient ethnic group, Dulong people, also live here without interference.
