Wang Dongxing (Chinese: 汪东兴; pinyin: Wāng Dōngxìng; Wade–Giles: Wang¹ Tung¹-hsing⁴; 9 January 1916 – 21 August 2015) was a Chinese military commander and politician, famous for being the chief of Mao Zedong's personal bodyguard force, the 9th Bureau of the Ministry of Public Security (which included the 8341 Special Regiment). Wang held many important positions, both in the Chinese Communist Party (CCP) and the government; he was Deputy Minister of Public Security in 1955–1958 and again in 1960–1970 and notably served as CCP Vice Chairman from 1977 to 1980, under Chairman Hua Guofeng.

Wang and his trusted security force played a very significant role in ending the Cultural Revolution by arresting the Gang of Four; however, Wang opposed Deng Xiaoping's proposed changes in economic policy, remaining loyal to Hua Guofeng and the continuation of the Maoist political line. As a result, when Deng consolidated power, he removed Wang from his government and Party posts, but did not harm him any further.

Wang was born to a peasant family in Yiyang County, Jiangxi on 9 January 1916. He joined the Communist Youth League of China in 1932, and the Chinese Red Army (the predecessor of the People's Liberation Army) in 1933, at the age of 17. He received military and political training at the Pengyang Infantry School and later at the Anti-Japanese Military and Political University. In 1934-35 he took part in the Long March, accompanying Mao to Yan'an. He later fought as an infantry officer in the war against Japan, and, after the defeat of the Japanese, in the Chinese Civil War, which led to the establishment of the People's Republic of China in 1949.

With the creation of the new Communist government, Wang Dongxing was named deputy director of the General Office of the Chinese Communist Party (an important bureaucratic position dealing with administration and personnel) and, crucially, Director of the 9th Bureau of the Ministry of Public Security, in charge of Mao Zedong's personal security detail, and also of protecting Zhongnanhai, the seat of government power. The 9th Bureau included the 8341 Special Regiment. Wang and his men were the only ones allowed to carry weapons inside Zhongnanhai. Mao trusted Wang, and made him responsible for checking the background of all staff serving in Zhongnanhai (not only bodyguards, but also waiters, cooks, secretaries etc.)^{[citation needed]}

Mao's continued trust and support led to Wang becoming, in 1955, Deputy Minister of Public Security, under Minister Luo Ruiqing. For "his efforts in public security work", Wang was awarded the rank of Major General of the Chinese People's Liberation Army, also in 1955.

In June 1958 Mao suddenly demoted Wang, sending him to Jiangxi as Director of the Provincial Land Reclamation Department. From February 1959 to August 1960, Wang served as member of the Standing Committee of the Communist Party Jiangxi Provincial Committee, and as vice president and Party Secretary of the Communist Labor University of Jiangxi.

However, in August 1960, Mao decided to recall Wang back to Beijing, and named him, again, chief of his bodyguards and Deputy Minister of Public Security, under Minister Xie Fuzhi (Xie was also very loyal to Mao). Throughout the chaos and instability of the Cultural Revolution, Wang remained a loyal and effective associate of Mao, although he couldn't prevent the Red Guards from denouncing and attacking many security officers of the Ministry of Public Security (Minister Xie explicitly allowed and even encouraged his favored Red Guard factions to attack security officials loyal to his predecessor Luo Ruiqing).

In 1966, at the start of the Cultural Revolution, Wang Dongxing was often seen in the great Red Guard rallies, sitting next to Mao's chauffeur in the open-top car from which Mao reviewed his supporters.
