Doctor Yin Zuluan works at a clinic in Guangsong Village, Dehong Dai and Jingpo Autonomous Prefecture, southwest China's Yunnan Province, Oct 17, 2016. Yin Zuluan's family thought she was quite stubborn as she refused to consider their repeated suggestions to quit her job as a doctor in a remote village in Yunnan Province. For 19 years, Yin has been spending most of her time in Guangsong Village, visiting her HIV-positive patients and raising the awareness of the villagers about how to control the deadly virus. The village borders the Golden Triangle, an area where Laos, Myanmar and Thailand meet, and where vast fields of poppies grow as ingredients for heroin-based drugs. [Photo/Xinhua]
