On this day, 51 years ago, on September 29, 1974 (August 14, 1974, the Central Committee of the Communist Party of China restored He Long's reputation. On September 29, 1974, the Central Committee of the Communist Party of China restored He Long's reputation. After Zhou Enlai's proposal and Mao Zedong's approval, the Central Committee of the Communist Party of China issued the "Notice on Restoring the Reputation of Comrade He Long", pointing out that Lin Biao had been deliberately trying to punish He Long for a long time. As early as 1966, he proposed to the Central Committee that He Long had asked the Kuomintang reactionaries in history. Issues such as "request for inclusion" and "conspiracy to usurp the army and oppose the Party" must be reviewed. Before the September 13th incident, the review of the He Long issue was always controlled by Lin Biao, Huang Yongsheng, Wu Faxian, Ye Qun, Li Zuopeng and others. After "September 13", the central government directly reviewed He Long's issue. After verification and screening by the central government: First, the so-called "collaboration with the enemy" issue is a complete reversal of history and a deliberate frame-up. 2. After investigation, there was no such thing as the so-called "conspiracy to usurp military power" and the "usurp military power" of people who supported some units of the military. 3. The so-called "February mutiny" by He Long is purely rumored. He Long died of illness on June 9, 1969. The central government decided to rehabilitate He Long and restore his reputation. Due to the interference and destruction of Jiang Qing, Kang Sheng and others, this rehabilitation was not complete, and some formulations were wrong. On October 16, 1982, the Central Committee issued the "Decision on the Complete Rehabilitation of Comrade He Long", speaking highly of Comrade He Long's life as "a life of combat, a life of revolution, and a glorious life." At the same time, the original Zhongfa Document (1974) No. 25 and Zhongfa Document (1968) No. 71 were revoked.
