[6] During the Boluan Fanzheng period after the Cultural Revolution (1966–1976), Beijing received a large number of visitors from Guangxi who arrived to report large-scale massacres and massive cannibalism, claims that were initially denied by the Guangxi Zhuang Autonomous Regional Committee of the Chinese Communist Party.
[3][6][7][9][10] The investigation teams were led by Li Rui, Zhou Yifeng (周一峰) and other senior officials from the CCP central leadership.
[7][8][9][10] In a span of approximately five years, the Guangxi CCP Regional Committee was re-organized and over 100,000 local officials were tasked with investigating and resolving the remaining issues from the Cultural Revolution.
[6][13] A research team led by Chinese historian Song Yongyi subsequently started to organize and compile the copies, eventually publishing them with Guoshi Press in the United States, as the Secret Archives about the Cultural Revolution in Guangxi, Classified Documents in 2016 followed by the Supplement in 2017.
[3][6][8][13] It took six years of effort by Song to secure each volume from a network of archivists, collectors and high-ranking Chinese officials who smuggled out documents.
