Qincheng Prison
Liu was a 28-year-old graduate when the 1989 demonstrations began. He organized the Beijing Students' Autonomous Federation and joined the movement's organizing body. As a result, he was sixth on a list of twenty-one activists whose arrests were ordered by the government. Liu went into hiding as a fugitive, but on 15 June 1989, Liu was arrested and charged with attempted subversion of the Communist Party of China. In 1991, he was convicted and sentenced to six years imprisonment at Qincheng Prison.
