Drone images show Kaidu River in northwest China's Xinjiang Uygur Autonomous Region embracing autumn as the trees on its banks turn yellow.

The yellow belts of trees, the green river and the city view create a picturesque scene. 

Kaidu, a major river in Xinjiang, and the wetlands nearby have become an important sanctuary for migratory birds like swans.
