Kang Sheng
Kang Sheng (; 1898 – 16 December 1975) was a Communist Party of China (CPC) official best known for having overseen the work of the CPC's internal security and intelligence apparatus during the early 1940s and again at the height of the Cultural Revolution in the late 1960s and early 1970s. A member of the CPC from the early 1920s, he spent time in Moscow during the early 1930s, where he learned the methods of the NKVD and became a supporter of Wang Ming for leadership of the CPC. After returning to China in the late 1930s, Kang Sheng switched his allegiance to Mao Zedong and became a close associate of Mao during the Anti-Japanese War, the Chinese Civil War and after. He remained at or near the pinnacle of power in the People's Republic of China from its establishment in 1949 until his death in 1975. After the death of Chairman Mao and the subsequent arrest of the Gang of Four, Kang Sheng was accused of sharing responsibility with the Gang for the excesses of the Cultural Revolution and in 1980 he was expelled posthumously from the CPC.
