On this day, 39 years ago, on August 14, 1986 (July 9, 1986, the lunar calendar), Chen Yun, Deng Xiaoping and Li Xiannian "handed over" the secret business. On August 14, 1982, Li Xiannian, Deng Xiaoping, and Chen Yun were in Beijing. In September 1986, the Sixth Plenary Session of the 12th Central Committee of the Communist Party of China decided that the 13th National Congress of the Communist Party of China would be held in October 1987. Held in Beijing. Time forbids anyone. Among the Standing Committee of the Political Bureau who presided over the Sixth Plenary Session of the 12th CPC Central Committee, Deng Xiaoping, Li Xiannian and Chen Yun are all in their 80s. The party's leadership collective must realize the replacement of the old as soon as possible. These issues have always lingered in the minds of the three elderly people... Chen Yun invited Deng Xiaoping and Li Xiannian to his home for a secret talk. Not long after the Sixth Plenary Session of the 12th Central Committee of the Communist Party of China, several old comrades who had fought with Chen Yun, Deng Xiaoping and Li Xiannian for decades passed away one after another, making them feel filled with emotion. On the morning of October 30, 1986, Deng Xiaoping and Li Xiannian came to Chen Yun's home as scheduled, and the three had a long secret conversation. It was a rare event for the three old people to meet alone, and the staff around them quickly took several photos of them. Before the people around him could finish their work, Chen Yun cleared the staff out of the office. The significance of this conversation was extraordinary. The importance of the content of the conversation can be reflected in the fragments later recalled by Chen Yun's guard Zhao Tianyuan: I had just walked to the duty room when the electric bell rang. I hurriedly turned back and opened the office door. When I saw Chairman Li standing up and walking towards the door. When I saw me coming in, the three old people all said loudly: "Cigarette, take the cigarette." I hurriedly asked Deng Xiaoping's secretary Zhang Baozhong for cigarettes... After the conversation ended, after Deng Xiaoping and Chairman Li left, I saw six filter cigarette butts in the ashtray. Deng Xiaoping smoked six cigarettes in 80 minutes. Among the three elderly people, only Deng Xiaoping smoked. The doctor had asked Deng Xiaoping to try not to smoke. However, Chen Yun and Li Xiannian were so eager to find cigarettes for Deng Xiaoping, which shows that the content of the conversation must involve major issues of the party and the country. The conversation was secret, and no one could know except the three of them, nor even the staff around him knew the inside story.
