Two disabled men, one blind, one a double amputee, have spent over ten years planting trees together in rural China.
To get to their plot, Wenqi, a double arm amputee, leads the way through a forest, guiding Haixia, his blind friend.
The elder of the two, Haixia, 54, was born blind in his left eye because of a cataract, and since a fragment of stone flew into his right eye during a factory accident in 2000, he has been totally blind.
So far they estimate they have planted ten thousand healthy trees, and three thousand more which have died. While the work may not be fast, the three-hectare site is now covered with trees and attracts nesting birds.
Haixia explains, "the whole riverbank had been bare for years and there were hardly any trees." But after a few years the trees grew, the area became greener and the villagers changed their attitude choosing now to assist the two men.
Their task is to grow as many trees as they can. It is a lengthy process which involves taking suitable cuttings from pre-existing trees, also planted by them, that have been growing over the last decade.
But if he does regain his vision, Haixia is adamant he'll carry on planting trees with Wenqi. "it doesn't matter if my eyesight comes back or not, I'm going to continue my work until my last breath," he says.
