In 2008, Peng was interviewed by
Jennifer 8. Lee for the documentary
The Search for General Tso (2014). In the documentary, Peng recalled in 1952 he was invited by the
Republic of China Navy to be in charge of a three-day state banquet during Admiral
Arthur W. Radford's visit of Taiwan. An alternative story proposed by Taiwanese food writer Zhu Zhenfan (2009) claimed
Chiang Ching-kuo, the son of President
Chiang Kai-shek, paid a late visit to Peng's restaurant when Peng ran out of ingredients. Chiang was served an improvised dish, General Tso's chicken, by Peng. The earliest news account on Peng was on November 13, 1968, and 15-24 January 1969 under the identical news heading "彭長貴的故事", published by
Economic Daily News (經濟日報) in Taipei. It is not clear whether his stories about his invention of the Tso's chicken were featured in those 1968-1969 news report. ==Personal life==
