(Clearwisdom.net) Ms. Guo Ailing, in her 40's, was a pharmacist employed by Daqing City No.2 Hospital in Heilongjiang Province. She used to have breast cancer before cultivating Falun Dafa and had an operation performed. After starting to practice Falun Dafa in 1996, she became strong and healthy and did not need chemotherapy any longer. She went to Beijing to appeal on behalf of Falun Gong in October 1999, was detained, and forced to publicly criticize herself in her work unit. From that point on, the police came to her home to harass her all the time. The stress of this harassment harmed her severely both mentally and physically. Her previous illness returned in 2001, and she died as a result of the persecution.
