Because of the unfair treatments against her, An went to the Beijing Public Security Ministry to appeal on May 21, 2000. She was escorted back and detained in the Education Committee Guest House. On May 24, An was given 15 days of administrative detention. An refused to sign the paperwork for her detention, and declared that she would reserve her right to appeal. Afterwards, she was sent to the Lubei Administrative Detention Center. On May 25, the second day of her detention, An was cuffed with a special type of handcuff nicknamed "bull's nose," for refusing to copy the rules of the detention center. To protest the ill treatments against her, An began a hunger strike. On June 6, 2000, An lost consciousness. She was unable to get up, and she suffered incontinence of feces and urine. The detention center gave her an emergency infusion, which had no effect. At 10pm, An was sent to the County Hospital. At 7:30am of June 11, 2000, An left this world.
