反右运动
At the 16th Communist Party Congress in 2002, Li wrote an open letter to Party Secretary Hu Jintao on political reform of the Communist Party. In the letter, Li argued that constitutionalism would lead the Communist Party away from political mishaps such as the Anti-Rightist Movement, the Great Leap Forward and the Cultural Revolution. In November 2004, the party's Propaganda Department banned Li from being published in the media.
