Li Ching-Yuen or Li Ching-Yun (simplified Chinese: 李清云; traditional Chinese: 李清雲; pinyin: Lǐ Qīngyún; died May 6, 1933) was a Chinese herbalist who supposedly lived to be over 256 years old. He claimed to be born in 1736, while disputed records suggest 1677. Both alleged lifespans of 197 and 256 years far exceed the longest confirmed lifespan of 122 years and 164 days of the French woman Jeanne Calment. His true date of birth was never determined. He was reported to be a martial artist, herbalist and tactical advisor.
Wu Chung-chieh claims that Li Ching-Yuen was born in 1677 in Qijiang County, Sichuan province. According to a 1930 New York Times article, Wu Chung-chieh, a professor of the Chengdu University, discovered Imperial Chinese government records from 1827 congratulating Li Ching-Yuen on his 150th birthday, and further documents later congratulating him on his 200th birthday in 1877. In 1928, a New York Times correspondent wrote that many of the old men in Li’s neighborhood asserted that their grandfathers knew him when they were boys, and that he at that time was a grown man.
