Han Jialan, 66, calls on her way to a black lung patient's home at Yuhe village, Zhong county in Chongqing municipality, May 16, 2012. Han lost her right arm at an early age but the inconvenience never stops her from helping people in need. Since 2006, she began to help the recovery of local black lung sufferers. Han said black lung disease cannot be completely cured. Patients can only relieve their pain through exercises, and that’s how she helps. She was dubbed the "armless angel" of the neighborhood.
