Wang Dongxing
Mao died in Beijing on September 9, 1976, and his mausoleum in Tiananmen Square was completed one year later. Less than one month after his death on October 7, 1976, the Gang of Four was arrested in Zhongnanhai by Mao's former security chief, Wang Dongxing, in a bloodless coup supported by Mao's anointed successor Hua Guofeng and military chief Ye Jianying. The arrests ended the Cultural Revolution. Deng Xiaoping was rehabilitated and then wrested power away from Hua. At the Third Plenary Session of the 11th CPC Central Committee held in December 1978, the Party, under Deng's leadership, rehabilitated the victims of Cultural Revolution, reversed the verdict of the April Fifth Incident, and adopted a policy course of economic reforms. College entrance exams were restored in 1977 and most of the rusticated youth returned to the city.
