The summer nomadic migration for more than 680,000 livestock is underway in Tekes County, northwest China's Xinjiang Uygur Autonomous Region. Starting Wednesday, over 5,200 local herder families will guide them through canyons, forests, and rivers on a journey of more than 70 kilometers to the summer pasture. 

The herders will move to an autumn pasture in September.

Xinjiang, home to lush pastures, is one of China's key livestock production base.
