# Project 571

Project 571 (Chinese: 五七一工程; pinyin: Wǔqīyī gōngchéng) was the code name given to an alleged plot to execute a coup d'état against Chairman Mao Zedong in 1971 by the supporters of Lin Biao, then Vice Chairman of the Chinese Communist Party. In Chinese, the numbers "5-7-1" (五七一; wǔqīyī) sound very similar to the term 'armed uprising' (武起义; wǔqǐyì). The Chinese Communist Party initially claimed that Lin Biao himself had devised Project 571, but evidence inside and outside of China has made it more likely that Lin's son, Lin Liguo, a high-ranking officer in the People's Liberation Army Air Force, instead developed the plot. Any plots that may have been planned or attempted by Lin Biao or his family ultimately failed. Lin's family attempted to flee China for the Soviet Union, but died when their plane crashed in Mongolia on September 13, 1971. A draft copy of the Project 571 outline was discovered following Lin's death, and was publicly circulated by the Chinese government as a means of explaining the event.

## Details of the plot

   Now he [Mao] has abused the trust and status given to him by the Chinese people, and has gone to the opposite direction historically. In fact, he has become the contemporary Qin Shi Huang. In order to be responsible to the Chinese people and Chinese history, our waiting and patience have limits! He was not a genuine Marxist-Leninist, but the greatest feudal tyrant in Chinese history who practiced the principles of Confucianism under the guise of Marxism-Leninism and the laws of Qin Shi Huang.
   现在他滥用中国人民给其信任和地位，历史地走向反面。 实际上他已成了当代的秦始皇，为了向中国人民负责，向中国历史负责，我们的等待和忍耐是有限度的！ 他不是一个真正的马列主义者，而是一个行孔孟之道借马列主义之皮、执秦始皇之法的中国历史上最大的封建暴君。
The outline was not written in the form of a practicable military plan, but more as a political declaration. Of the nine sections of the outline, only two deal directly with military strategy; the remaining sections either criticize the policies of the Cultural Revolution or attack the personality of Chinese leader Mao Zedong. Because the writers of the outline apparently lacked both the military knowledge and the ability to mobilize large groups of forces, Western scholars generally reject the possibility that Lin Biao could have personally planned Project 571.
Of the sections which deal with military strategy, the outline's authors mention the support of a number of disparate forces, none of which were overwhelmingly powerful. The plotters believed they were supported by the equivalent of approximately six to eight Air Force divisions: the Fourth and Fifth Air Force Corps; the Ninth, Eighteenth, and Thirty-Fourth Air Force Divisions; the Thirty-Fourth Tank Regiment; and (perhaps unusually) the Bureau of Civilian Aviation. The authors also noted that they expected the support of an "auxiliary force" composed of the Twentieth and Thirty-Eighth Armies (Lin's own elite units) and several provinces, which were only vaguely mentioned. The power of this combination of forces was not great, compared to the rest of the People's Liberation Army, and the authors of the Outline noted that "at present the preparation of our strength is still not adequate".
The military plans contained in the outline were below the standards that could have been expected from Lin, one of modern China's most successful generals. Because he was a master of maneuvering ground forces, it is unusual that he would have relied almost exclusively on the Air Force, even though his own elite forces were readily available to him. In the Chinese Civil War, Lin had become a master of delaying decisive confrontations until he knew that the chances of victory had become overwhelming, and scholars note that it would have been out of character for Lin to have staked his political career on such a poorly planned military coup, whose chances of success were slim. There is no direct evidence that suggests that either Lin or his generals were involved in the coup plot. Many scholars believe that his son, Lin Liguo, a high-ranking officer in the People's Liberation Air Force, was instead the author. Within China, the theory that Lin Liguo drafted the outline for Project 571 was corroborated by the testimony of Lin's generals in the special trials of the "Lin Biao and Jiang Qing Counter-Revolutionary Cliques", which were held in 1980.

## History of the plot

Following Lin's death in 1971, the Chinese government initially charged him with personally planning Project 571. After the testimony of Li Weixin (the only one of the alleged plotters to have survived up to 1971), and the 1980 testimony of General Huang Yongsheng (a former military chief-of-staff whose role in the plot was implied by Li's testimony), sources within China have generally come to recognize that Lin Liguo devised the plot independently of Lin Biao. Western scholars have been critical of the Chinese government's perspective since 1971, and generally state that Lin Liguo was the author of the plot. Some Western historians question whether Lin Biao was even aware of Lin Liguo's plans at all.
According to a modern standard Chinese narrative of Lin Biao's plot, he became aware that Mao no longer trusted him after the Second Plenum of the 9th National Congress of the Chinese Communist Party in 1970, and he harbored a strong desire to seize supreme power. In February 1971, Lin and his wife Ye Qun (who was then a Politburo member) began to plot Mao's assassination. In March 1971, Lin Liguo held a secret meeting with his closest followers at an Air Force base in Shanghai. At this meeting, Lin Liguo and his subordinates supposedly drafted Project 571. Later that March, the group met again to formalize the structure of command following the proposed coup. The other major plotters were high-ranking military officers, including Zhou Yuchi, Yu Xinye, and Li Weixin.
From March 23 to 24, Yu Xinye drafted the outline for Project 571, the original manuscript of which was said to have been recovered after the death of the coup plotters. In the outline, Lin Liguo's party listed a total of eight ways to eliminate Mao Zedong: among them were blowing up his train, collapsing a railway bridge as his train was crossing it, using napalm, and simply using a handgun to assassinate him.
Mao was unaware of the coup plot, but in August 1971 he scheduled a conference for September to determine the political fate of Lin Biao. On August 15, Mao left Beijing to discuss the issue with other senior political and military leaders in southern China. On September 5, Lin received reports that Mao was preparing to purge him. On September 8, Lin decided to speed up the coup and gave the order to his subordinates to proceed with Mao's assassination, under the direction of Lin Liguo and Zhang Yuchi (who was then the deputy director of the Office of the Air Force Headquarters).
Lin's subordinates planned to assassinate Mao by sabotaging his train before he returned to Beijing, but Mao unexpectedly changed his route on September 11. Mao's bodyguards foiled several subsequent attempts on his life, and Mao safely returned to Beijing in the evening of September 12. By failing to assassinate Mao, the coup attempt associated with Project 571 failed.
After realizing that their coup attempt had failed, Lin's party first considered fleeing south to their power base in Guangzhou, where they would establish an alternative power base and cooperate with the Soviet Union to attack armed forces loyal to Mao. After hearing that Prime Minister Zhou Enlai was investigating the incident, they abandoned this plan as impractical, and decided to flee to the Soviet Union instead. In the early morning of September 13, Lin Biao, Ye Qun, Lin Liguo, and most of the other major plotters attempted to flee to the Soviet Union and boarded a prearranged Trident 1-E, (a CAAC B-256) piloted by Pan Jingyin, the deputy commander of the PLAAF 34th division. But the plane crashed near Öndörkhaan in Mongolia on September 13, 1971. Everyone on board, eight men and one woman, were killed.
After September 12, a massive purge of the armed forces took place. All military officials identified as being close to Lin or his family (most of China's high military command) were purged within weeks of Lin's disappearance. Within a month of Lin's disappearance, over 1,000 senior Chinese military officials were purged. After he was confident that all of the alleged plotters were either dead or arrested, Mao Zedong had copies of the Project 571 outline widely circulated among cadres in the Chinese Communist Party (relatively senior members only: level 19 and above). The official Chinese version of events was drafted by Zhang Chunqiao and his subordinates under Mao's personal supervision.

## Codes used in the outline

## Aftermath

It is generally believed that the criticism of Mao Zedong in the "Project 571" is extremely damaging to Mao Zedong's personal image. Therefore, there are different opinions within the Politburo Standing Committee of the Chinese Communist Party on whether to issue this Project to the public. However, Mao Zedong ignored the dissuasion of Zhou Enlai and others and insisted on publishing the full text of the Project. Regardless of Mao Zedong's motives, this objectively played an enlightening role in revealing the inside story of the Cultural Revolution, and its potential impact is very far-reaching.
A few years later, language similar to the relevant words in the minutes appeared in the "April 5th" poem in Tiananmen Square in early April 1976. For example, a famous poem in Tiananmen Square at that time wrote: "China is no longer the China of the past, and the people are not stupid. The feudal society of Qin Shi Huang is gone forever. We believe in Marxism-Leninism, and what we want is the true Marxism-Leninism." This poem is obviously influenced by the Project 571 from its thinking to its text. Eventually the Cultural Revolution ended with the death of Mao Zedong and the arrest of the Gang of Four.
