Mr. Ma, 36, an HIV carrier from Henan, invites passers-by to take "smiling" photos with him, together with university volunteers in Wuhan, central China's Hubei province, November 21. Ma said he hopes to collect 10,000 "smiles" before December 1, the World AIDS day, to appeal against discrimination against HIV carriers and patients in life and employment. He has collected nearly 8,000 photos after visiting six cities. [Photo:cnhubei.com]
