Chen Yun (simplified Chinese: 陈云; traditional Chinese: 陳雲; pinyin: Chén Yún, pronounced [ʈʂʰə̌n y̌n]; 13 June 1905 – 10 April 1995) was one of the most influential leaders of the People's Republic of China during the 1980s and 90's. He was also known as Liao Chengyun (廖程雲); it is unclear whether this was his original name or a pseudonym he used during his underground work in Shanghai. He was one of the major political leaders of China both during and after the Chinese Civil War along with Mao Zedong, Liu Shaoqi, Zhou Enlai, Zhu De and Ren Bishi and was later considered to be one of the Eight Elders of the Communist Party of China.
A native of Qingpu (now part of Shanghai), Chen was one of the few Communist Party organizers from an urban working-class background; he worked underground as a union organizer in the late 1920s, participated in the Long March, and served on the Central Committee from 1931 to 1987. He was active throughout his career in the field of economics, despite receiving no formal education after elementary school.
