Li Ching - Yuen from
China lived 256 years, born in 1677 in the town of Qi Jiang Xian in the
Szechuan province. He was a martial artist and a tactical adviser and he
died in 1933, having over 200 descendants during his life span and
surviving 23 wives.
How did he do it?
Ching-Yuen is reported to have lived off a diet of herbs and rice wine
inculding lingzhi, Goji Berries- wild ginseng, he shou wu and gotu kola.
Is there proof?
In a 1930 New York Times article, Professor Wu Chung-chieh of the
University of Chengdu found Imperial Chinese government records from
1827, congratulating Li Ching-Yuen on his 150th birthday.
Further documents later congratulate him on his 200th birthday in 1877.
