Cui Xiaojuan, 40, was a lecturer at the Daqing City Police Academy. On July 22, 1999, she joined other practitioners to hold a group appeal for Falun Gong in front of the Helongjiang Province Administration Building in Harbin (the capital of the province). From there, she then directly went to Beijing to appeal for Dafa and was arrested in Tiananmen Square. Because she refused to give the police her name and address, she was detained at the Beijing Changpin Detention Center as "Unknown #1." The police physically abused her numerous times.

After she conducted a ten-day hunger strike, they even forced her to stand outside under the scorching sun at the height of the summer for three days. After she was detained there for about a month, the police from her hometown of Daqing recognized her, brought her back, and threw her into the local detention center for 15 days. After her release, because she refused to promise to give up Falun Gong, she was detained at her workplace, where she was allowed no outside contact. Her employer returned her to the detention center for another 15 days, as she still refused to give up Falun Gong. They tried to send her to the labor camp but did not get the permission to do so, so they continued to hold her illegally at her workplace. On December 30, 1999, because her father signed her name for her on a huge flag that reads "Falun Dafa is good," (which was then sent to the People's Congress to appeal for Dafa), she was sent back to the detention center again. On the way to the detention center, she was allowed to go home to pick up some clothes under police escort. She jumped from the balcony of her home on the fifth floor. She chose to give her life to protest her illegal detainment and to defend Dafa.

That was the first time that she had been allowed to go home during the past six months. Her husband (a fellow practitioner), wearing handcuffs and ankle shackles, was escorted from the local detention center to attend her funeral. According to her husband, the last time he saw Xiaojuan, her face looked so peaceful and serene. She went to a better world with a smile on her face.
