In March 2006, Ms. Zhang went to her aunt's house to do some business, but was arrested by waiting police. The police from Tongdong Street Station in Tiefeng District detained her in Qiqihar City First Detention Center. When officials from the City 610 Office, City Police Department, and Teifeng District Department were visiting the Detention Center, Ms. Zhang shouted "Falun Dafa is great!" The guards got angry, hitting her mouth with a mop very hard, causing it to bleed. At the end of October 2006, Ms. Zhang went on a hunger strike to protest. She was later taken to the Hepingchang City Hospital in a deep coma. She had difficulty breathing, was incontinent, and vomited blood in large quantities before her death. A female guard said, "She would be fine even if she vomits half a pan of blood." At around 1:00 a.m. on December 4, 2006, Ms. Zhang died as the result of the tortures in the Hepingchang  Hospital.
