四个现代化
Wei did not publicly voice his feelings until 1978, when he decided to take part in the newly emerging Democracy Wall movement which was then taking place in Beijing. On 5 December 1978, he posted an essay which he authored on the wall. Entitled "The Fifth Modernization," Wei's essay was a response to Paramount leader Deng Xiaoping's essay, the Four Modernizations. The basic theme of Wei's essay is that democracy should also be a modernization goal for China along with the other four modernizations which were proposed by Deng (the four modernizations were : industry, agriculture, science and technology, and national defense).
