Photo exhibition focuses on cotton fields

Wang Zilin won the first prize for his photos called Field of Hope.

He pictures show a cotton grower in the Xinjiang Uygur autonomous region whose family rely on a 13-hectares cotton field for their liveilihood.

"They pin their hopes on the harvest each autumn, and this inspired me to record their battle with the nature," says Wang.

He says photography is the same as growing cotton. "How much you gain depends on the amount of pain you can endure."
