Just a few of the things I've added to the timeline recently, or at least relatively recently:

Zhou Enlai's activities, travels, and writings from the beginning of the May Fourth Movement (1919) until his return to China from Europe in September 1924, from the Biographical Chronology of Zhou Enlai, 1898–1976 周恩来年谱 (1898–1976) by the Central Institute of Party History and Literature 中央文献研究室.

The activities, travels, speeches, and reports of Mikhail Borodin (鲍罗廷) in China from 1923 to 1927 during the first period of KMT–CCP cooperation, and of M. N. Roy (罗易) in 1927 during the first KMT–CCP split.

Some important dates and texts in the transition to simplified characters in 1955 and 1956.

References to D. N. Aidit in the Biographical Chronology of Mao Zedong, 1949–1976 毛泽东年谱 (1949–1976) by the Central Institute of Party History and Literature 中央文献研究室.

Speeches by Jiang Qing and others during the Cultural Revolution, from Jiang Qing 江青, The Essential Selected Speeches of Comrade Jiang Qing 江青同志讲话精选集 (Twenty-first Century Cultural Revolution Press 21世纪文化革命出版社, 2024).

For the last few months, in my spare time, I've been puttering away on a day-by-day timeline of the Chinese revolution. I've just crossed the 100,000 words threshold and I feel like I've barely started. One discovers all kinds of interesting things proceeding in this way. I'll present it in a more comprehensive way once I figure out a good way to do that. As far as I know, nothing like it currently exists in English.

The story of Robert F. and Mabel Williams' trip to China is fairly well known among people who study the international dimensions of the black liberation struggle in the US. They arrived in China in late September 1963 and first met Mao in the afternoon before the National Day parade in Beijing on October 1. Guo Moruo was also at that meeting. (Mao's "Statement Calling on the People of the World to Unite Against the Racial Discrimination of US Imperialism and to Support the Struggle of American Negroes Against Racial Discrimination," published on August 9, 1963, was written in response to a request from Robert.)

The evening before (so, September 30), Mao, Liu Shaoqi, Zhou Enlai, Deng Xiaoping, and other senior leaders held a reception for representatives from Indonesia, Cuba, and Algeria, where they chatted with D. N. Aidit, General Secretary of the Communist Party of Indonesia. It wasn't the first time Mao met Aidit and it wasn't the last. Earlier that day, Aidit had delivered a report on "The Indonesian Revolution and the Immediate Tasks of the PKI" to the Higher Party School of the CPC Central Committee. Exactly two years later, the September 30 Movement, for which Aidit's PKI was blamed, triggered the mass killings in Indonesia in 1965–66.

Two meetings with Mao, then, that have been covered entirely separately by scholars working in very different fields of history happened on consecutive days. I knew before that Mao had met all of these people, but I hadn't realized that he saw one of them at a reception one evening, went to bed, got up the next morning, and met the others.
