Located on the Qinghai-Tibet Plateau, the Sanjiangyuan area is home to the headwaters of the Yangtze, Yellow and Lancang rivers, which help to nurture billions of lives.

Hence it is also called China's water tower.

The stunning glaciers and snow mountains stand on the "Third Pole," and inhabitants such as snow leopards and blue sheep are tenacious. All the creatures are also vulnerable as the area is sensitive to climate change.

In Sanjiangyuan National Park, ecological protection and development of pastoral areas are carried out in a coordinated manner. Tens of thousands of public service jobs are provided for conservation and ecological restoration.
