"The Act of Killing" (Indonesian: "Jagal" ) is a 2012 Danish-British-Norwegian documentary film directed by Joshua Oppenheimer, Christine Cynn, and an anonymous Indonesian co-director.
 The film explores the social significance of the Indonesian mass killings of 1965–1966 by focusing on the perpetrators and having them produce reenactments of the killings in the style of various Hollywood genres.
 The film's primary subjects had been petty criminals, but came to lead a powerful death squad during the anti-communist purge which resulted in the death of an estimated 500,000–2,000,000 suspected communists, communist sympathisers, alleged leftists, and ethnic Chinese.
 As many of the institutions and people responsible remained in power, those who carried out the killings were never held to account and continue to hold positions of power and respect.
 Oppenheimer was struck by the extent to which people not only rationalised but boasted about their participation in the killings, and used the film to explore the role the events continue to play in people's lives in the present.
 According to Oppenheimer, it is "about a regime in which genocide has, paradoxically, been effaced and celebrated – in order to keep the survivors terrified, the public brainwashed, and the perpetrators able to live with themselves."

Shanghai Orphans (Traditional Chinese: 上海孤兒;Simplified Chinese：上海孤儿； pinyin: Shàng hǎi gū ér; officially romanized to State‘s children【國家的孩子】) refers to The People's Republic of China during the Great Chinese Famine, when around 3000 Shanghai orphans were transferred to the Inner Mongolia Autonomous Region.
The Three Years of Great Chinese Famine (), referred to by the Communist Party of China as the Three Years of Natural Disasters (), the Three Years of Difficulty () or Great Leap Forward Famine, was a period in the People's Republic of China between the years 1959 and 1961 characterized by widespread famine.
 Drought, poor weather, and the policies of ruler Mao Zedong contributed to the famine, although the relative weights of the contributions are disputed due to the Great Leap Forward.
Yang Jisheng (born November 1940) is a Chinese journalist and author of "Tombstone" (墓碑; "Mubei"), a comprehensive account of the Great Chinese Famine during the Great Leap Forward.

 He promptly joined Xinhua News Agency, where he worked until his retirement in 2001.
 His loyalty to the party was destroyed by the 1989 Tiananmen Square massacre, and, although he continued working for the Xinhua News Agency, he, in fact, spent much of his time researching for "Tombstone".
 As of 2008, he was the deputy editor of the journal "Yanhuang Chunqiu" in Beijing.
 Yang Jisheng is also listed as a Fellow of China Media Project, a department under Hong Kong University.

Hungry Ghosts: Mao's Secret Famine is a book written by Jasper Becker, the Beijing bureau chief for the South China Morning Post.
 Becker argues that the American press reported the Great Chinese Famine with accuracy, but leftists and communist sympathisers such as Edgar Snow, Rewi Alley, and Anna Louise Strong, remained silent or played down its severity, when Mao Zedong's Great Leap Forward had turned into a horrible tragedy.
 Becker concludes that the tragedy could have been averted after the first year if Mao's senior advisers had dared to confront him.
The Great Leap Forward () of the People's Republic of China (PRC) was an economic and social campaign by the Communist Party of China (CPC) from 1958 to 1962.
 The campaign was led by Chairman Mao Zedong and aimed to rapidly transform the country from an agrarian economy into a socialist society through rapid industrialization and collectivization.
 However, it is widely considered to have caused the Great Chinese Famine.
Mao's Great Famine: The History of China's Most Devastating Catastrophe, 1958–62, is a 2010 book by professor and historian Frank Dikötter about the Great Chinese Famine of 1958–1962 in the People's Republic of China under Mao Zedong (1893–1976).
