Before her death, Ms. Pang Fengzhi, 56, was a retired high school teacher at the Number 3 High School, Hailar, Inner Mongolia. She started practicing Falun Gong in 1997. In February 2000 and February 2001, Ms. Pang went to appeal for justice for Falun Dafa in Beijing. During the second appeal, she was arrested in Beijing and sent back for over a month's detention in the local jail. On March 15, 2001, Ms. Pang was put into a brainwashing camp held by the local 610 Office, and was arrested again in a large-scale arrest around July 19 that year because the authorities found a Falun Dafa banner in her home. Later Ms. Pang was jailed for 3 months and developed esophageal cancer in prison. National Security agents Qu Shulin, Gao Feng, and others persecuted her for long time and harmed her health. She died on August 18, 2002, after being released.
