"Li Peng's June 4 Diary" was published by Bao Park, the son of Bao Tong, the political secretary of former CCP General Secretary Zhao Ziyang. Based on a manuscript of a diary allegedly kept by Li Peng during the June 4 Tiananmen Square incident, the book was originally scheduled to be published in Hong Kong by New Century Press on June 22, 2010. At the time of the June 4, 1989 Tiananmen Square incident, Li Peng was a member of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee (CCP Central Committee) and the Premier of the State Council. The diary covers the period from April 15, 1989 to June 24, 1989, when Li Peng was a member of the Politburo Standing Committee and Premier of the State Council. Bao Park said that, apart from converting the diary from the original simplified Chinese characters to traditional Chinese characters, "nothing will be added, nothing will be subtracted, and nothing will be changed" in the book. The book was later published in the United States.
The author of this book was a reporter for "Sing Tao Daily" and was stationed in Beijing at the end of April 1989 to cover the democracy movement. The book is divided into six main parts: Square Facts records the course of the 1989 democracy movement, from the author's visit to Beijing in April to the early morning of June 4, when she and the masses were evacuated from Tiananmen Square. The second part concerns post-hijacking memories, which are some of the author's interviews from 1989. The third part concerns the interviews. The author had interviewed 7 student leaders and intellectuals that year. The leaders told her the reasons why they devoted themselves to the student movement. The fourth part is about the rest of the author's life, from June 4 to December 1990. The author has recorded some fragments of her speeches to the secondary school students in Hong Kong. Some of them are sentimental, some of them are confessional, and all of them are sincere and heartfelt. The fifth part is "Twenty Years of Wounds," which is a reminiscence written by the author on the 20th anniversary of June Fourth. The sixth part is about the grassroots of June 4. These grassroots actors have been pretty much forgotten. The author wanted to write a biography of the grassroots of June 4 in order to fill in gaps in history.
