On June 30, 2021, a group of wild ducks frolic and forage among lotus leaves at the Swan River scenic spot in Korla City of Bayingolin Mongol Autonomous Prefecture, northwest China's Xinjiang Uygur Autonomous Region. The picture of waterbirds roaming freely adds more fun to the summer scenery.

In recent years, Korla City has continuously strengthened the environmental protection efforts, and the number of wild birds inhabiting the river sections has continued to increase. (Correspondents: Yang Houwei, Zhang Xinhua)
