北京之春
After Mao died, the democracy movement restarted in 1978, when the brief liberalization known as Beijing Spring occurred after the Cultural Revolution. The founding document of the movement is considered to be The Fifth Modernization manifesto by Wei Jingsheng, who was sentenced to fifteen years in prison for authoring the document. In it, Wei argued that political liberalization and the empowerment of the laboring masses was essential for modernization, that the Communist Party was controlled by reactionaries and that the people must struggle to overthrow the reactionaries via a long and possibly bloody fight.
