Where there is love, nothing is impossible, according to a 71-year-old retired teacher who has helped more than 200 addicts quit drugs, guiding them out of their dependence through the care she provides in the Guizhou provincial capital.

"I never treat the drug addicts as addicts, or criminal suspects, when I contact and talk to them," Huang Yongfu said. "On the contrary, I treat them as my own children who need my help and mother's love."

After her retirement, Huang established a volunteer association, the Association of Sunshine Mothers, and began helping addicts in local communities in Guiyang's Huaxi district.
