Qiu Huizuo (Chinese: 邱会作; Wade–Giles: Ch'iu Hui-tso; April 16, 1914 – July 18, 2002) was a lieutenant general of the People's Liberation Army (PLA), best known as one of the "four guardian warriors" of Vice Chairman Lin Biao during the Cultural Revolution.

According to Qiu's autobiography, shortly before the Communists' forced exodus from their base in Jiangxi, he was almost executed by party intelligence officials who thought he possessed too much sensitive information regarding military logistics.

[2] By the time the Communist forces arrived in northern Shaanxi, Qiu was tasked with logistical work, ensuring that the army had sufficient supplies.

[2] After the Chinese Civil War resumed between the CCP and Kuomintang in 1945, Qiu served in Manchuria as political commissar of the Eighth Column of Lin Biao's Fourth Field Army.

At the Lushan Conference in 1959, Defence Minister Peng Dehuai was purged for criticizing Mao Zedong's Great Leap Forward and replaced by Lin Biao.

The senseless mistreatment of Qiu was one of a series of events that pushed marshals Nie and Ye to voice their displeasure with the Cultural Revolution during the February Countercurrent, the last serious phase of dissent in the senior ranks of the party during the movement.

[1] At the 9th National Congress of the Chinese Communist Party in 1969, Qiu and many other PLA generals emerged as the main beneficiaries of the Cultural Revolution after the destruction of the old guard.

Of Lin Biao's inner circle, Qiu was said to have a good attitude during the proceedings, openly confessing to the charges and kneeling in front of Lt. Gen. Tang Ping's widow to seek her forgiveness.

[5][1] He was released in 1987 after serving his full sentence, and resettled in Xi'an where he reunited with his family and was afforded some basic benefits from the state as well as a living stipend of about 200 yuan a month.

[5] Qiu wrote an autobiography, released in Hong Kong in 2012, which includes details on the intrigues of the Cultural Revolution and his relationship with Lin Biao.
