Wang [2], please print and distribute it to the Politburo comrades for study. The handling of
this case [3] may be wrong. At that time, we listened to Lin Biao’s [4] one-sided statement.
Mao Zedong
March 25, 1972

[1] On March 18, 1972, Yang Chengwu's daughter Yang Junsheng wrote to Mao Zedong and
others, saying that Yang Chengwu was loyal to Chairman Mao and that he had been
politically framed by Lin Biao, Chen Boda, and Ye Qun. She requested that Yang Chengwu be
allowed to undergo the test of class struggle.
[2] Wang refers to Wang Dongxing, who was then an alternate member of the Political
Bureau of the CPC Central Committee and Director of the General Office of the CPC Central
Committee.
[3] Refers to the "Yang, Yu, and Fu Incident."
[4] Lin Biao, formerly Vice Chairman of the CPC Central Committee and Vice Chairman of the
Central Military Commission. During the Cultural Revolution, he formed a counterrevolutionary group with Chen Boda and others, and colluded with and competed with the
Jiang Qing counter-revolutionary group to seize high-level leadership power in the Party and
the state. After his conspiracy was exposed, he fled by plane on September 13, 1971, and
died in a plane crash fleeing China. In August 1973, the Central Committee of the Communist
Party of China passed a resolution expelling Lin Biao from the Party. In 1981, a special
tribunal of the Supreme People's Court of the People's Republic of China confirmed him as
the principal offender in the counter-revolutionary group case.
