Qiao Shi
Unlike his peers, most notably Jiang Zemin and Li Peng, Qiao Shi did not attend even the most important events on the Chinese political calendar after he retired, including the successive party congresses, National People's Congresses, the opening ceremonies of the Beijing Olympics, or various anniversaries of historical events. In 2012, he published the book "Qiao Shi On Democracy and Rule of Law", which received significant attention from both domestic and international media. That Qiao Shi, a normally low-profile figure content with retirement, would publish such a work in his old age led to speculation that the book was a veiled criticism against the perceived deterioration of the legal and security portfolio under security chief Zhou Yongkang. In 2014, Qiao Shi donated 11 million yuan to the China Legal Exchange Foundation, whose goal was to promote justice and the rule of law.
