Li Ching-Yuen or Li Ching-Yun (simplified Chinese: ???; traditional Chinese: ???; pinyin: Li Qingyún) (1677 or 1736 – 6 May 1933) was a Chinese herbalist, martial artist and tactical advisor, known for his supposed extreme longevity.
He claimed to have been born in 1736, while disputed records suggest 1677, implying an age at death of 197 and 256 years, respectively.
Both far exceed the highest verified ages on record.
His true date of birth was never determined, and his claims have been dismissed by gerontologists as a myth.
While his claims have never been verified, they have been widely circulated as an Internet hoax.
