Sixty-two-year-old Ma Sanxiao, a former recon scout with no feet, looks at a newly planted tree in  Shixing, Hebei province on April 26, 2011. Ma has spent 10 years planting more than 3,000 trees in the remote mountainous area where a waste land has taken its greenery. His story inspired many people when he was spotted by a photographer who uploaded a video clip about him on Internet. [Photo/Xinhua]
